Free Wi-Fi networks in SF, San Jose join hands through Hotspot 2.0 | PC World

My Comments

The Wi-Fi Passpoint or Hotspot 2.0 technologies have been made available to allow those of us with mobile devices to benefit from public-access Wi-Fi without having to deal with Web-based sign-in routines every time we want to use these facilities. But they have been pitched primarily at mobile phone operators and ISPs who want to offer Wi-Fi service for their subscribers.

But San Francisco and San Diego have implemented this technology as part of their free public-access Wi-Fi setup, which I see as being a first for this class of public-access Wi-Fi. Typically these services implement a Web-based login routine which occurs at the start of each session and this may be provided in order to assent to the service’s terms and conditions. With these setups, it becomes impossible to continue a usage session even if you move out of the network’s scope temporarily and it also becomes impossible to roam between the different locations ran by the service without having to log in again.

What they have done is to prove that the Wi-Fi Passpoint or Hotspot 2.0 technology can work well with single-location or multi-location public-access Wi-Fi setups whether free-to-access or pay-to-access. For example, a chain of restaurants, a public-transit system or a community Wi-Fi setup can benefit from this by allowing the users to move between locations without a need to log in again.

The next question that may be raised is to simplify the provisioning experience, especially when it comes to provisioning the same service across multiple devices owned by the same user. This may range from setups where you simply assent to terms and conditions through services where you establish a session-based account like most docket-based hotspot setups to the services offered by WISPs and telcos which are based on an existing customer account.

Who knows, this could be the trend for easy-to-use secure public-access Wi-Fi as different scenarios are being tested.

WiFi and Satellite Equipped Tractors to Follow Yorkshire’s Tour de France | ISP Review

My Comments

The Tour De France 2014 is starting off in Yorkshire UK and is an event that moves from location to location depending on where the péléton are cycling in this race. As I have seen for myself when I have watched this cycle race on SBS TV, it attracts huge crowds with various locations of flat land near the race route resembling caravan parks due to the many motorhomes showing up at each point because people hire these so they can follow the race by vehicle.

This time, the National Farmer’s Union in the UK have answered to the needs of the connected spectator by setting up mobile Wi-Fi hotspots. But how have they done this even though access to decent broadband in rural areas is non-existent? They have equipped two tractors with a public-access Wi-Fi hotspot consisting of a Wi-Fi hotspot router connected to a satellite-broadband modem provided by Avonline Satellite Broadband (now Bigblu Broadband). This means that each tractor has its own satellite bandwidth which is distributed by Wi-Fi over a range of 500 metres from where it is parked.

Locations

One question that has been raised is whether the mobile hotspots and their satellite backhauls would cope under the pressure of many spectators tendering the images and video they take to multiple social networks using these networks. This is similar to situations that hoteliers would encounter when their guest-access Internet services are at capacity as all of the guests download multimedia content at the same time.

As well, it is an example of using network equipment powered from motor vehicles i.e. the Massey-Ferguson tractors to provide Internet access and making sure that the equipment does survive the distance with uneven power-supply conditions that this entails. I see this also appealing to other rural districts like France’s rural districts who want to cater to the connected visitor who attends a special event like a fair, rally or a cycle road race like the Tour De France.

Update (15 June 2018)

Due to corporate restructuring affecting Avonline Broadband, the satellite ISP mentioned in this article, which has led to it being rebranded to Bigblu Broadband, I have readjusted the Web link for this ISP and references to the name to reflect these changes.

VPNs and remote access in the home and small-business space – a lot of unanswered questions

From the horse’s mouth

Linksys

Product Page (LRT-224)

My Comments

I was skimming through a SmallNetBuilder review of the Linksys LRT-224 VPN endpoint router and came across a feature that could appeal to those of us who are creating “box-to-box” VPNs between networks.

This feature is called “Easylink VPN” and requires the creation of an account username and password on the destination router and the user to supply to the origin router  the outside (WAN) IP address, account username and password for the destination router to establish a “box-to-box” VPN.

I do see some limitations with this concept as it is applied nowadays. One is that it is set up to work onliy with VPNs that have the Linksys LRT-2×4 series VPN routers at each end which doesn’t bode well for the goal of an interoperable easy-to-set-up VPN.

Similarly, there isn’t a way of identifying whether an IP-address conflict could occur once the VPN is established. As well, there isn’t support for dynamic-DNS setups which can make things easier for people who implement most residential and small-business Internet services that are “DHCP-only” rather than having the option to create an IP address.

But what I see of this is an attempt to allow home-office-plus-shopfront business operators and similar users to create a “box-to-box” VPN between locations without creating extra room for mistakes during the setup and provisioning phase/ It could also work well with the UPnP RemoteAccess and ContentSync profiles as part of the goal of a multiple-device personal “cloud”.

AVM Fritzbox 3490 to be able to update itself like your Windows or Mac computer

One of the big holes in data security that has been recently identified is the typical Internet gateway device sold to most households and small businesses as the “edge” between their home network and Internet connection.

This hole has been identified because most of the devices, especially those sold through most retail, value-added reseller and most service-provider channels, work simply on the firmware installed in them when they left the factory. As we all know, a lot of this firmware can be full of bugs and software exploits that place the home network and the computer equipment on it at risk of security breaches.

Most regular and mobile computer equipment and some set-top boxes benefit from a continual update process with the ability to have the critical updates delivered by the software vendor automatically without any user intervention. But this doesn’t hold true for the typical consumer router, which requires the customer to install updated firmware manually. In a lot of cases, the user may either have to run a firmware-installation tool on their regular computer or download a special firmware-package file from the manufacturer’s Website and subsequently upload the firmware to the device via its Web-based management interface.

A few devices may allow you to deploy updated firmware by causing the device to download and install the latest firmware from the manufacturer’s Web site by clicking on an “Update” button. These devices make the job easier but you have to regularly visit that user interface to check for new updates and start the update process.

These tasks can be considered very difficult for anyone to do unless they have had a lot of computer experience and expertise and is something commonly performed by the computer expert in the family or community.

AVM, a German company who makes premium-grade routers and networking gear for consumers and small business, have answered this need with the latest firmware for the Fritzbox 7490 Internet gateway device. This firmware offers automatic updating for firmware patches to enhance the device’s security.and reliability.

You would have to visit the AVM site to download and install the latest firmware in to the Fritzbox 7490 but this would be the last time you would need to do this because the Fritzbox could simply “look after itself” when it comes to the updates. There is a question remaining about whether AVM will roll this feature out to other Fritzbox routers and network devices so as to keep them secure.

At least AVM are setting a good example for all Internet-gateway-device manufacturers and resellers to follow by putting up the idea of self-updating equipment in to the consciousness. This could even extend to other devices like smart TV and devices that constitute the “Internet Of Everything” as we think of the smart home.

UPnP+ links non-IP devices to wide-area networks | EETasia

My Comments

The recent extension of the UPnP Device Architecture specifications, known as UPnP+ is being worked on at the moment by the UPnP Forum. This is to extend the reach of the UPnP Device Architecture specification sets to satisfy certain new realities.

One key reality is to make UPnP work properly with the “Internet Of Everything” concept. This is where devices are able to interlink with each other and share their information in a manner not dissimilar to the concept associated with the Internet.

It will be achieved with native support for IPv6 across IP networks. This takes advantage of the huge number of addresses this standard offers compared to the legacy IPv4 which most of the Internet works on at the moment.

As well, a SensorBridge Device Class will be defined. This caters for the “bridge” device that links sensors and similar devices that work on non-IP networks with IP-based networks. The article talked of the non-IP wireless-sensor networks as being Zigbee, Z-Wave and ANT which take advantage of low-power low-overhead operation suited for those fields. These devices could be represented by “black-box” devices that stand between an Ethernet or Wi-Fi-based home network and the sensors or controllers such as the Honeywell Evohome Mobile Access Kit, but could also be represented as software integrated in either a router that also has a Zigbee or Z-Wave interface or a smartphone, tablet or laptop with Bluetooth 4.0 Smart interface.

There will also be inherent support for cloud-based “hosted” services to be part of the UPnP ecosystem. Of course, I find that the term “cloud” alludes a lot to services hosted by other parties away from the main home network, typically to provide remote access from smartphones, tablets and other computers connected via the Internet. In the context of “Internet Of Everything”, it could extend to service providers like utilities or monitored-alarm companies using this data to participate in the “Smart home” concept.

I would see this come in to its own with home and other networks that are operating along the line of “Internet Of Everything” and this could be supported with newer devices that have newer UPnP+ firmware in place.

Freebox Révolution to be a VPN endpoint

Free.fr have been adding some extra functionality to their Freebox Révolution and Freebox Crystal “n-box” Internet-gateway devices. This is being delivered through a free firmware update (version 2.1.0) as in the nature of the highly-competitive French Internet-service market and users can download and implement them in these devices.

VPN Endpoint Router

One key product is the ability for a Freebox Révolution or Freebox Crystal Internet-gateway to become a fully-fledged small-business-grade VPN router. Here, you could set these devices to work as an endpoint for a client-to-box VPN or, perhaps, a box-to-box VPN joining two small networks via the Internet backbone. For example, you could set up a secure-browsing or secure-file-transfer link to your home or small-business network in Paris or even buy a Draytek VPN router for your home network in the UK and a Freebox  Révolution for that chic French “bolthole” and establish a “box-to-box” VPN for backing up data between both locations, including making the same media available at both locations.

This is made feasible with hardware or software endpoints that work to PPTP or OpenVPN technology, which would suit software endpoints available on all the main desktop and mobile platforms as well as most other VPN endpoint routers.

Even the “seedbox” BitTorrent client integrated in these devices has been updated to be able to take advantage of the VPN functionality for user privacy.

Wi-Fi network improvements

The Freebox Révolution has been able to benefit from a software-based 802.11ac implementation which opens it up to high-speed data transfer with 802.11ac clients. Typically this would have required one to replace or add hardware to upgrade to the newer 802.11ac standard.

Similarly, the firmware has mad it easier for a Freebox user to optimise their Wi-Fi network performance by changing the channel the Wi-Fi access point is working on. It also includes a “site-survey” function which lists what Wi-Fi networks are operating on what channels at what strengths so you can choose the right channel to work on. This can be important in a neighbourhood where everyone is running a home network and could make things also easier for Free’s technical-support staff.

There is even the ability to turn Wi-FI functionality on or off according to a schedule which can be of importance for people who are sensitive to RF emissions or need to keep a lid on out-of-hours access to the Wi-Fi network.

Conclusion

You just never know what Free or other French ISPs have in store to increase the real value that they offer to their customers in that highly-competitive market.

The home network to eventually be part of the car

Article

How To Network-Enable A Bus | Lifehacker Australia

My Comments

This article talked about implementing a 3G / Wi-Fi network in a Sydney transit bus to facilitate the Opal “touch-on touch-off” smartcard ticketing system in these buses. But it may also apply to other realities such as Internet access in the car or the car being part of the home network. This is being taken further with the desire for access to online or hard-disk-based infotainment systems that are likely to become the norm for today’s vehicles whether as a factory-supplied option or something installed after the fact.

Moving between different areas

Even pleasure-boats will be considered as part of the networked world

One major issue is that the vehicle will be required to move between its primary network which could be your Wi-Fi network in your home or a marina’s Wi-Fi network to an Internet service provided by a mobile-broadband service. Here, this will require effectively a smooth switchover between these different services in order to provide a smooth Internet connection to network-connected devices such as an online-capable infotainment system and / or a small Wi-Fi network within the vehicle or boat.

The uneven power situation in vehicles

Another challenge is the power issue. Here, if the vehicle’s or boat’s engine isn’t running, the car battery is supplying the power from a finite resource and there also has to be a sufficient amount of current left in the battery to start the vehicle. But when you are starting the vehicle, there is a significant current dip that occurs while the starter motor is in operation. This is something you may notice where your car’s interior light will dim as you are starting the engine and you have one of the vehicle’s doors open. Once the engine has just started to run, there will be a surge of current which is typically limited by various regulator circuits in all of the vehicle’s equipment.

How was this worked around?

The installation was based around a customised Netcomm router that worked between a particular Wi-Fi network at the depot or Telstra’s 3G mobile broadband when on the road. This router was shoehorned to cope with the abovementioned power issue encountered in vehicles and boats most likely with a significant amount of extra circuitry so that it draws the minimum amount of current when the ignition is off but draws its normal amount while the engine is running. This extra circuitry also is about the provision of a regulator to allow it to cope with the current dip / surge that occurs when the bus driver turns the key to start the engine.

Vehicle builders like BMW, Chrysler, Ford and GM who have worked on the “online vehicle” have developed in-vehicle network equipment from the ground up when developing prototype or production in-vehicle routers for these projects. Typically these would have a mobile broadband setup as the primary setup and have perhaps a WI-Fi LAN for use with tablets and similar devices as well as a specialised Ethernet setup for the online infotainment setups.

In the context of the online personal vehicle or boat, it will mean that if the vehicle is at home, it can connect to the home network and do an update process for maps, AV content and similar material. Then when you are on the road, you could gain access to Internet-hosted content like traffic information, current “open/shut” status reports of nearby businesses, the location of cheapest fuel prices, and audio content from online services like Spotify or Internet radio.

This issue will be faced further as the in-vehicle network becomes as much a must have for vehicle enthusiasts as the souped-up car sound system. It will mean the availability of aftermarket routers that are designed for in-vehicle use along with connection standards for aftermarket infotainment setups that work online whether with a smartphone or their own network / Internet access.
