‘Wi-Fi Ready’ ruse snuffed out by ACCC | The Age

My Comments

I have given a fair bit of space in HomeNetworking01.info to the issue of “Wi-Fi Ready”, including writing an article dedicated to this issue. This is where consumer electronics that are marked as “Wi-Fi Ready” can work directly with a Wi-Fi segment only if they are equipped with a dongle or module that the manufacturer sells at an exorbitant price.

In some cases, these dongles or modules don’t perform as they should and is something I had observed with a TiVo that being demonstrated at a consumer-electronics show a few years ago. Here, the PVR was being connected to a 3G Wi-Fi router via the official USB dongle that was to be used with this device but the unit, which was in a metal AV rack as part of a large-screen demonstration, threw up “out-of-range” error messages even though the router was in the stand opposite the demonstration space.

I even though of the issue where a manufacturer could have equipment not able to connect to a home network via Ethernet or Wi-Fi unless the customer purchases extra accessories through them. This is although most of these “Wi-Fi ready” TVs, Blu-Ray players and other consumer-electronics equipment, like the Sony BDP-S380 that I previously reviewed, have an Ethernet socket so you can connect them to an Ethernet (or HomePlug AV powerline) segment.

Other situations that could come of this include customers having to order the modules through the manufacturer or distributor rather than picking them up from their favourite retail outlet. Or a requirement that a technician has to fit the module to the TV or other device, requiring either a service call or the equipment sent to a workshop for this to happen, which also entails extra cost to the consumer.

Now the Australian Competition and Consumer Commission have taken steps in tackling this issue. Here, they have required the main consumer-electronics brands to qualify this statement in their promotional material that they provide to consumers and retailers about these products. This means they have to mention in the brochures that the customer has to buy the module to enable this feature.

Previously, whenever the European TV manufacturers provided the ability for customers to have add-on modules installed in to their TVs to enable functions like teletext, stereo audio reception or picture-in-picture, they would emphasise in the promotional material that these were options for the sets concerned. This put in to the customers’ minds that you didn’t necessarily get the feature with the set.

The European Union could tackle this issue using a directive; and other consumer-protection agencies could make sure that this issue is raised concerning “Wi-Fi ready” consumer electronics.

But what was never looked at was the continued availability of the extra-cost accessories that enable these functions. This can definitely affect TV sets that typically serve more than 10 years with older units being “pushed down” to secondary areas like bedrooms.

What can typically happen is that, as part of superseding a model, a manufacturer could cease to supply the accessories available for that model and design similar-function accessories for the newer model so they don’t work with the product in question. When the consumer-protection departments look in to this issue, they should raise the issue of having customers able to use newer accessories to enable prior models using the lessons learnt from computer design.

Similarly newer standards concerning the network interface will arrive and customers could be limited in to using accessories that only support the older standards. This can happen as the Wi-Fi wireless-network standard evolves to faster technologies or is able to use newer frequencies.

These issues such as disclosing whether extra-cost accessories are needed or whether such accessories are available beyond the equipment’s lifecycle need to be looked at to encourage a consumer-friendly experience when buying network-capable consumer electronics.

thinkbroadband :: FTTC Etherway, cheaper access to business grade broadband

My Comments

Most small businesses typically head for a consumer-based Internet-access setup which has a reduced upload rate. This can be a limitation for these businesses if they dabble with cloud-based computing, IP-based telephony or IP-based video-surveillance.

If they do want this improved upload speed, the business would have to go for an Ethernet-based service that uses the high-throughput Ethernet protocols. Such services are primarily offered as “Metro Ethernet” copper services or FTTP fibre-optic prices at a price that fewer small businesses can afford.

But BT Openreach are offering a wholesale fibre-copper service that provides Ethernet-type connectivity rather than DSL-type connectivity that is pitched at households. This is mainly for the Etherway fibre-copper setups pitched at small business and professional setups and provides the high reliability that would be expected for this kind of computing.

A question that I would have is whether the copper run is Ethernet-based DSL or Metro Ethernet which uses Category-5 twisted-pair copper cabling similar to that used in Ethernet LANs. It would encompass this ability as well as the cost-effectiveness of these fibre-copper next-generation broadband setups.

Integrated HomePlug AV Ethernet switch with power outlet

Homeplug AV socket by Power Ethernet offers slimline speedy home networking – Recombu

From the horse’s mouth

Product page

My Comments

There is another way that the HomePlug technology is being taken further in the UK. Here, this device resembles a regular UK double power outlet and is installed in a regular double-gang wall bracket.

But you have a single 13-amp UK power outlet plus a 4-port 10/100 managed Ethernet switch. It then connects to a HomePlug AV 200Mbps powerline network segment that rides on the existing ring-main wiring. Business users who value functionality like VLANs can benefit from the Ethernet switch being a managed type.

The Website pitched this unit as being a network on-ramp or off-ramp for a HomePlug AV segment and cited applications like historic buildings where modifications to power outlet locations may be against the heritage-protection rules for these buildings.

Personally, I would recommend this kind of outlet to be compliant to HomePlug AV2 and would be best suited to projects where you are reorganising power outlets in a room or building. In the home, it would be more applicable for locations where a cluster of computing or audio-video equipment would exist. I would also value it as being useful for caravans or temporary buildings or, for that matter, any outbuilding application.

Similarly, the “Power Ethernet” unit could be made available with an integrated 802.11n Wi-Fi access point for “infill use” in covering wireless-network black spots but it is easy to think of this device as being something that can provide HomePlug in a semi-permanent manner.

Improvements taking shape for better public wireless Internet access

Wi-Fi Alliance Begins Certification For Automatic Hotspot Connection – SmallNetBuilder

My Comments

The Wi-Fi Alliance are taking proper steps to make the user experience for wireless-hotspot services more user friendly and secure. This is based on the “Passpoint” standard which covers logging in and a secure usage session.

It has been driven by wireless-broadband providers who want to use these hotspots and their wired-broadband backhauls as a data offload in busy areas. One key improvement is to implement WPA-Enterprise security with session-unique security parameters rather than the common WPA-PSK security which uses a common password.

The login experience has also been tackled through the provision of a consistent experience that isn’t depending on a Web-based form. Here, the credentials could be a username/password combination that is presented by the device’s native user interface, or credentials held on the device or in a SIM card.

This may open up hotspot access to headless or limited-display devices like digital cameras, car infotainment systems or handheld games consoles. But a question that could be raised is whether it could be feasible to have a group of devices seen as a logical network that can exist through the hotspot’s space. This issue may play in to setups like multiplayer multi-machine gaming amongst a group of teenagers or young adults in the same cafe or bar.

Another question worth raising about Passpoint is whether a venue is able to have control over its Wi-Fi access? This would be of concern with anyone in the food-beverage-hospitality industry who would rather that patrons who use the venue’s Wi-Fi are the ones who are buying food and drink or renting a room.

This function has also been extended beyond just logging in to the network and Internet service. A Passpoint setup has also had the ability to factor in application-level authentication needs like content access. An example of this application is the in-room movies service offered by nearly every hotel. Here they could allow a person to stream a movie to a tablet or laptop and view this anywhere around the premises such as the lobby lounge.

One risk that I see for Passpoint or any other “easy-setup” standard promoted by the Wi-Fi Alliance is that the same old situation will repeat itself. This is where Apple won’t implement the standard in their products or platforms even though they consider themselves the “super-cool” IT brand. I have seen this for myself with WPS where just about everything except a MacBook Pro or an iPhone will enroll with a Wi-Fi segment using this “push-button” setup routine.

These standards could be implemented not just with an operating system but also in a software form which is based around a program that can be loaded on to a device by its user and that such software is available through device platform’s app store without any need for the device to be jailbroken.

Understanding WiFi DIrect

29/06/2012 Wireless Networking No Comments

There has been the desire to see IEEE 802.11-based Wi-Fi wireless networking work as one of the many  way of interlinking computer devices without wires.

The standard and preferred practice with this technology is to implement an access point which all data in the wireless-network segment, which is typically connected to an established wired network or the Internet.

But there is a desire to link these devices in a safe and secure way without using a hardware access point or router as an interlinking device. This would lead to a “wireless personal area network” for devices like cameras, printers, network media players and smartphones.

What is Wi-Fi Direct

Kingston Wi-Drive and Android smartphone

The Kingston Wi-Drive in this setting is an example of what Wi-Fi Direct is all about

A Wi-Fi Direct setup requires software in a client device like a computer or smartphone to make it work as an access point using its software. This can be made obvious through a smartphone running a “Wi-Fi tether” mode where it works as a Wi-Fi router using its wireless-broadband service as a WAN.  Similarly, a mobile-NAS device like the Kingston Wi-Drive is effectively supporting this function through the use of its own Wi-Fi access point. Another example is a laptop computer running Inte’s “My Wi-Fi” software to bridge its connection that it has with a public wireless hotspot to an Internet radio in order to allow it to pick up an Internet broadcast stream.

The setup would require that the network be secured using a WPA2-PSK security protocol and is able to be set up using WPS “push-push” or PIN setup methods. They also use UPnP and/or Bonjour to set themselves up for their functionality at higher levels of the protocol stack. This can allow a user to find devices that have particular functions like file transfer, media streaming or printing and is exploited in smartphone applications as a means of rapidly transferring large file clusters.

A Wi-Fi Direct device can host current Wi-Fi-based client devices like most consumer network printers as well as other Wi-Fi Direct devices. As well a cluster of devices hosted by a Wi-Fi Direct device is considered as a Wi-Fi Direct Group. This can represent a one-to-one relationship or a one-to-many relationship with the Wi-Fi Direct.

Some devices like laptops running Intel MyWiFi can be set up to support a concurrent link to a Wi-Fi network such as a home / small-business network or a wireless hotspot while being able to maintain a Wi-Fi Direct cluster.

How to go about using Wi-Fi Direct

Wi-Fi Personal-Area Network concept diagram

If you intend to set up a Wi-Fi Direct group, determine the main computing device that is in the group. This could be a laptop, a tablet or a smartphone that has this functionality. On the other hand, you could use a DLNA-enabled network-attached-storage that supports Wi-Fi Direct as the main device if you are, for example, playing tunes held on the NAS to something like the Sony CMT-MX750Ni music system.

Then enable the Wi-Fi Direct functionality on this device and connect the other devices using WPS or a pre-determined WPA-PSK password key.

The range of this network will be determined by the radio range that the Wi-Fi Direct “master” device can provide; and this may be small for a lot of battery-powered devices like handheld games. Some devices that use a non-Wi-Fi connection like Ethernet or HomePlug may break off this connection if they are working as a Wi-Fi direct “master” device.

Increasing the relevance of Wi-Fi Direct

Wi-Fi Direct can be used in digital cameras as a way of uploading photos to a Wi-Fi NAS or a laptop or simply using a laptop’s Internet connection for providing photos to a social network. It can also work well as an alternative to Bluetooth for printing or media playout; as well as a wireless link to desktop peripherals like keyboards and mice.

The Wi-Fi Direct technology can then come in to its own with local multiplayer multi-machine gaming whether this involves laptops, smartphones, tablets or handheld gaming consoles. A game publisher could write a game to support a multiplayer mode over a local network as well as an online environment. This then allows one to “verse” an opponent in a game wherever they are without it costing money in data charges or dealing with the login requirements that a hotspot may throw at the potential competitors.

Similarly, if a device does support Wi-Fi Direct as well as a wired connection, it could support an “extended-service-set” function so as to cater for environments where there is a problem with Wi-Fi coverage in certain areas.

Conclusion

Once you know what you are doing, you can make Wi-Fi Direct devices work properly for creating “as-needed” Wi-Fi networks for differing applications.

WPS-capable access points and multi-access-point networks

13/05/2012 Network Management, Wireless Networking No Comments

Just about every wireless router or access point targeted at the consumer or, in some cases, SOHO/small-business market is equipped with Wi-Fi Protected Setup, commonly known as WPS. The obvious part of this feature is a button on the router that instigates a quick and easy enrolment routine for suitably-equipped wireless network client devices.

Here, you would instigate the WPS setup routine on the client device, which may be as simple as starting Wi-Fi network setup. In all versions of Microsoft Windows since Windows 7, you would have your computer searching for wireless networks through the “Add Wireless Networks” routine.  But you may find that you have to select the target network you want to connect to in newer versions of Windows and click or tap “Connect” where Windows will prompt for the passphrase but will tell you that you can use the WPS button on your router if the network supports this. Then you would press the WPS button which begins to securely transfer the network credentials to the client device. In some cases, if you unpack a new router and plug it in to the wall, you may be determining a new WPA-PSK passkey for that router.

But you may be wondering how this will affect those wireless networks that have two or more access points that have this feature yet are set up to extend a wireless network’s coverage.

Last Saturday, I had an opportunity to set up such a network by repurposing a broadband router with this feature as an access point to extend a wireless network past a corrugated-iron wall to the back of a newly-extended house. Luckily the house was wired for Ethernet as part of the renovation, so the wired backbone of this “extended-service-set” was the Cat5 Ethernet cabling. But most of you may simply use a HomePlug AV powerline network as your backbone for a similar network.

Both the network’s main ADSL modem-router and the broadband router, which was floating around as a spare, were recent-issue units equipped with WPS. They were configured with different channels but the same ESSID, wireless-technology and security parameters and the broadband router was set up as an access point with its DHCP server turned off and itself existing on a fixed IP address that was part of the network.

I had discovered a problem with this broadband router where it reset the wireless-network parameters after a WPS wireless-network-setup cycle. But you need to check that the settings stay by going to “Advanced”, “Wireless Setup” or “WPS” options in your router’s / access point’s management Web page and making sure that options to keep wireless-network settings are selected after you configure the device with your network’s SSID and security parameters.

This means that WPS-equipped access points and routers are capable of working in the “extended-service-set” arrangement. It then means that you can enrol new Wi-Fi client devices like Windows 7 laptops, Android smartphones or Internet radios to your wireless-network segment using that idiot-proof WPS “push-push” method at the nearest access point to where you are setting them up at. Yet the multiple-access-point network still does the job of extending wireless coverage in to the dark spot while allowing you to move the laptop, tablet or smartphone between the access-points’ coverage areas without reconfiguring anything.

Note: I have updated the article originally published on May 2012 to added some extra notes about the WPS setup experience for versions of the Microsoft Windows regular-computer operating system released since this article was originally published.

Customer-supplied line-filters to give VDSL2 setups the same promise of self-install as ADSL2

09/05/2012 Network Management, Next-generation broadband service No Comments

Article

thinkbroadband :: Openreach in technical trial to test micro-filters with FTTC service

My comments

Previously ADSL required a truck-roll to the customer’s premises to provide the service. Here, the technician installs a DSL line splitter at the line’s entry point and a socket for the ADSL modem. Now installs don’t need a technician to visit unless they are difficult or sophisticated setups like dealing with business phone systems or monitored security systems.

Typically, the customer installs a micro-filter or ADSL line splitter on each phone device and connects the ADSL modem-router to a socket that doesn’t have a micro-filter attached to it or connects the modem to the ADSL or DATA port of the line splitter. In most cases, we tend to use DSL line splitters rather than line filters at each phone socket. This can allow us to move the ADSL modem-router around as needed to suit different living arrangements or simply to relocate the wireless router for best performance.

Most fibre-copper next-generation broadband setups such as FTTC, FTTN or FTTB typically will implement VDSL2 but this is a different kettle of fish when it comes to provision. Here, a technician still visits the premises to put in a VDSL2 central splitter and run Ethernet-grade cable to where the VDSL2 modem-router would be installed.

BT Openreach are trialing the use of selected line filters and splitters as a way of providing self-installation of VDSL2-based fibre-copper setups. They are assessing these for radio and audio interference and degradation of data throughput with the commonly-used line filters attached to existing phone equipment.

Initially, the tests will be based around professionally-installed setups, but they will move towards self-install setups. It could also then give the same level of flexibility that we have enjoyed with ADSL2 equipment.

These tests could be observed by other countries and companies interesting in deploying fibre-copper next-generation broadband that uses VDSL2 technology; but can also be used as a way of justifying these setups over fibre-to-the-premises setups.

Making sure your small business is ready for IPv6

HP Blogs – 6 steps for SMBs to become IPv6-ready – The HP Blog Hub

My Comments

There is all the talk of us running out of IPv4 public IP addresses for the Internet, and an increased awareness of IPv6 Internet technology. One major driver for the IPv6 technology is the rolling out of next-generation broadband services; where this feature will be seen as being part of the “next generation” mould.

In the near time, the typical IPv6 network will operate as a “dual-stack” setup where there is an IPv6 network and an IPv4 network operating over the same network space. A device such as an IPv6-ready router will typically bridge the gap between the dual-stack devices and the IPv4-only devices by assisting in the discovery of the devices and transferring data between the two different network stacks.

Outside IT contractors

If you do regularly engage outside contractors for your IT needs such as your POS / property-management technology, it would pay to ask whether the technical staff know about IPv6 and how to deploy it. Most of these contractors may think that small business doesn’t need IPv6 but as the Internet moves to this technology, it pays to be future-proof.

ISPs and Webhosts

It is worth making sure that your business’s ISP and Internet hosted services such as your Webhost are ready for IPv6 or have intentions to roll out a customer-facing IPv6 service.

Most ISPs and Webhosts are likely to have the backend of their services working on IPv6 technology but their customer-facing services like the Web services or Internet service may not be ready. This may be due to the presumption that most customer setups will fail when confronted with IPv6. The exception may be the ISPs that serve a “switched-on” audience that knows their way around the Internet technology; or ISPs and Webhosts that offer customer-facing IPv6 service as a limited-user beta test and they may offer a “dual-stack” setup.

It also pays to check that your domain host supports domain records that are compatible with IPv6 setups. This includes having AAAAA-form DNS records that can resolve your domain name to IPv6 addresses.

Hardware

Computers that run Windows Vista or 7, MacOS X Lion or recent Linux distributions will be ready for IPv6; with Windows XP having support through a downloadable module from Microsoft’s Web site. Relatively-recent computer equipment can be upgraded from prior operating systems to the newer IPv6-compliant operating systems. For the mobile platforms, the IOS (iPhone / iPad / iPod Touch), Android, Symbian and Windows Phone 7 platforms do support IPv6. They will typically operate on a “dual-stack” arrangement by being able to service an IPv4 network and an IPv6 network at the same time through the same network interface,

Similarly, most network printers pitched at the business end of the market that were released over the last few years would have support for IPv6 in a dual-stack setup.

As for routers, managed switches, access points and other network hardware, I would suggest that you check for firmware that supports IPv6 for your existing equipment. Keep an eye on the manufacturer’s Website for newer firmware updates that support IPv6.  If you are purchasing or specifying newer network equipment, make sure that it does support IPv6 or has future support for this in a planned firmware update. Most unmanaged switches, HomePlug-Ethernet bridges and devices that don’t use a Web or SMNP user interface would not need to be compliant with IPv6. This is because these devices work at levels below the IP stacks.

In the case of routers, the device should work as a “dual-stack” unit with support for routing between the two different IP network types. It should also be able to cope with working with a dual-stack Internet service especially as the business Internet services that provide IPv6 will do so in a dual-stack manner.

When I review any network hardware including printers, I will identify those pieces of equipment that are IPv6-ready so as to help you know whether the equipment will be future-proof.

Software

As for software on these computers, any desktop firewall software or other network-utility software that you run would need to support IPv6 operation. This is something that recent versions of this software would cater for, but you should make sure of this when you specify new software. It also holds true for any other network-management programs that need to work on an IP level.

The application software that serves office functionality or line-of-business needs wouldn’t be of concern in relation to IPv6 because the operating system would be handling the network-resource requests for these programs.

Conclusion

The key issue with assuring IPv6 compatibility for your small business network is to make sure that your computer equipment works on dual-stack IPv4/IPv6 software and / or there is a router that works as n IPv4/IPv6 bridge on both sides of the network-Internet “edge”. As well, the IT contractors and services that you engage would need to be knowledgeable about IPv6 and the impending rollout for your business.

Security issues concerning field-updatable device software raised in HP lawsuit

13/12/2011 Data security, Network Management, Network Security No Comments

Article

HP sued over security flaw in printers | Security – CNET News

My comments

An increasing trend that I have covered on this site and have noticed with equipment that I have reviewed is for the equipment to be updated with new firmware after it is sold to the customer.

Field-updating practices

Previously, this practice involved the device’s user using a regular computer as part of the update process. In a lot of cases, the user would download the update package to their computer and run a special program to deploy the update to the connected device. If the device, like a router, was connected via the network, the user uploaded the update package to the network-connected device via its management Web page or other network-file-transfer methods.

Now it is becoming more common for one to update the software in their device without the need to use a regular computer. This would be done using the setup options on the device’s control surface to check for and, if available, load newer firmware. 

It also includes the device automatically polling a server for new firmware updates and inviting the user to perform an update procedure or simply updating itself during off-hours for example; in a similar vein to the software-update mechanisms in Windows and MacOS.

As well, an increasing number of devices are becoming able to acquire new functionality through the use of “app stores” or the installation of add-on peripherals.

The HP lawsuit concerning printer firmware

Just last week, there has been a lawsuit filed against HP in San Jose District Court, California, USA concerning weaknesses in the firmware in some of their printers allowing for them to accept software of questionable origin. Issues that were raised were the ability to load modified software that could facilitate espionage or sabotage. This was discovered through lab-controlled experiments that were performed on some of the affected printers.

As all of us know, the firmware or apps are typically held on servers that can be easily compromised if one isn’t careful. This has been made more real with the recent Sony PlayStation Network break-ins, although data pertaining to users was stolen this time. But it could be feasible for a device to look for new firmware at a known server and find compromised software instead of the real thing.

They even raised the question not just about the software that is delivered and installed using a computer or network but the ability to install ROM or similar hardware chips in to the device to alter its functionality. I would also see this including the ability to pass in code through “debug” or “console” ports on these devices that are used to connect computers to the devices as part of the software-development process.

This could have implications as equipment like home appliances, HVAC / domestic-hot-water equipment and building security equipment become field-programmable and join the network all in the name of “smart energy” and building automation. Issues that can be raised include heaters, ovens or clothes dryers being allowed to run too hot and cause a fire or building alarm systems that betray security-critical information to the Social Web without the users knowing.

Further ramifications of this lawsuit

Device manufacturers will have to look at the firmware that governs their products in a similar vein to the software that runs regular and mobile computing equipment. This includes implementing authenticated software delivery, software rollback options and the requirement to keep customers in the loop about official software versions and change-logs (differences between software versions).

In some cases, business computing equipment like laser printers will have firmware delivered in a similar manner to how computer software is rolled out to regular computers in larger businesses. This includes software that enables centralised firmware deployment and the ability to implement trial-deployment scenarios when new firmware or add-on software is released.

Devices that have proper-operation requirements critical to data security or personnel / building safety and security may require highly-interactive firmware delivery augmented with digital-signature verification and direct software-update notification to the customer.

Similarly, security-software vendors may push for a system of integrating software solutions, including “edge-based” hardware firewall appliances in the process of software delivery to other devices.

Conclusion

What I would like to see out of this case if it is allowed to go “all the way” is that it becomes a platform where issues concerning the authenticity, veracity and safety of field-updatable firmware for specific-purpose devices are examined.

What is this private cloud functionality being touted with NAS devices?

22/11/2011 Network Management, Network Media Devices No Comments
Netgear ReadyNAS - the heart of the personal cloud

The NAS as the heart of the personal cloud

I am seeing increasing reference to the “cloud” concept in marketing literature for consumer and small-business network-attached storage devices by their vendors. It is typically talked of in the concept of a “personal cloud” surrounding the NAS device and is used across the product range.

Examples of this include Western Digital’s My Book Live NAS, PogoPlug USB file servers and Iomega’s “Cloud Edition” NAS range.

What it is about

This feature is primarily about an easy-to-establish remote-access system for the NAS device so you can gain access to the files on this device from the Internet. The manufacturers tout this as an alternative to storing data on public-cloud file-storage services like Dropbox, iCloud, Windows SkyDrive or setting up private FTP or HTTP access to the data-storage facility your ISP or Web host may provide.

It is based on the NAS having vendor-supplied software to link with a cloud-based service that makes it easy to locate on the Internet even if you use a regular dynamic-IP Internet service. The vendor may supply desktop and mobile software to facilitate this discovery and / or establish a user-subdomain or directory name that is part of their “remote-access” service domain.

Of course, your data still resides on the NAS with the vendor’s service cloud being the Internet-side discovery link for the device. As well, all of these personal clouds use encryption of a similar standard to what is used to secure your Internet-banking session.

This idea has been existing for over the last few years with vendors providing their simplified remote-access solutions for their NAS products but they are using the current emphasis on cloud-computing technology as a marketing tool for this functionality. This is in a similar vein to how online services have been marketed using the cloud term even though they use this concept.

How can it be taken further

Currently this cloud concept is being exploited further with smartphones and tablets by the NAS vendors providing free data-access apps on their platforms’ app stores. Here the apps allow the users to use the mobile device’s user interface to transfer the desired data between the NAS and the device’s local storage. Some of us would see it as a way to offload picture data from the smartphone to the DLNA-enabled NAS or pull down important data to the smartphone or tablet.

Netgear is even working with Skifta to provide remote access to media content on its ReadyNAS units and allow a PC or Android phone to share the content from the remote ReadyMAS device with DLNA-compliant AV equipment.

The Iomega solution is implementing the Personal Cloud concept as a backup and peer-to-peer replication setup; as well as a remote-access method. But as more manufacturers get on the bandwagon, there may be the issue of providing a vendor-independent “personal cloud” in order to encourage competition and innovation.

What should my network have

The network has to have a router that is set up for UPnP IGD functionality at its network-Internet “edge” for the cloud-based remote access to run properly. This will apply to most retail and ISP-supplied routers, but you may have to make sure this function is properly enabled.

You don’t need to have a fixed IP address or a “DynDNS” program running on your equipment to have this personal cloud operate because the vendor-supplied software on the NAS takes care of the location and access function. But it should have a reliable Internet connection and you may want to put the NAS and network-Internet “edge” equipment on a uninterruptable power supply to assure high availability even with rough power supply conditions. It may be worth reading this article that I wrote about keeping “sanity” on your home network during periods of power unreliability if you want to keep that personal cloud alive.

But avoid the temptation to use a Wi-Fi wireless connection to connect a NAS to your router, even if the NAS does have Wi-Fi connectivity. Instead, connect it to your router with an Ethernet cable, so you have reliable operation.

Conclusion

In the context of the consumer or small-business network-attached storage system, the “cloud” feature is simply being used as a way to describe a simplified remote-access environment for these devices.
