My comments

It is so easy for land and building developers to hawk the possibilities of new technology like fibre-optic communications when they sell their properties. This was increasingly done through the 1970s to the 1990s as a way of stating that the development was “ready for the future” and is still practised today with some residential-commercial developments. In a lot of these cases, there really isn’t a way of benchmarking the quality and capacity of the fibre-optic technology that goes in to these locations and knowing whether they really live up to the expectations.

The French government have taken a step in the right direction with the “Zone d’Activité Très Haut Débit” (Very High Bandwidth Business Zone) where there is a particular logo for fully-qualified developments.

Here, they required the following standards of the infrastructure for the development to be “logo-compliant”:

• Next-generation broadband to be delivered by optical fibre to every property
• A minimum service bandwidth of 100Mbps symmetric “to the door” 
• Provision for the competitive delivery of next-generation broadband by several retail providers.

This was to be supervised by SETICS in order to assure throughput and competitive-service compliance.

The current shortcomings that I find with this project is that it doesn’t qualify residential developments or the provision of next-generation broadband to the tenancy units (offices, shops, apartments) in a multiple-tenancy building like an office block, shopping centre or block of flats. These kind of developments are where there is the likelihood of hyping-up broadband infrastructure that falls short of the mark.

What needs to happen with this is to extend the logo standards to residential developments and multiple-tenancy buildings owned or managed by a particular entity. As well, local government should be involved in the promotion of the minimum-standard next generation broadband service so that if they have a logo like the “ZA THD” logo, they can become attractive to the “switched on” residents and businesses.

My Comments

I was sent an email about this article at InternetServiceProviders.Org which is a new “at-a-glance” Internet-service directory for the USA. It outlines the common terms that will bamboozle people when they buy Internet service; especially as they read, listen to or watch the advertising that the ISPs will run.

But I have always and will always advise Internet customers to consider multi-service deals which encompass regular or mobile telephony, and / or multi-channel pay TV as well as the broadband Internet. This is especially more so if you already have an ongoing telephone or pay-TV service and you want to start purchasing Internet service.

One thing that I would like to see from this site is a continual news feed about situations that will affect retail Internet service in the US. This includes service-provider behaviour like recent Comcast issues; the provisioning of improved Internet service such as fibre-optic Internet or efforts to bring broadband to rural areas.

Introduction

I am reviewing WiFi Analyzer which is an elementary wireless-network site-survey tool for the Android platform. This program is free-to-download but is ad-supported with ads that can be suppressed for a few weeks at a time through a user option. There is also the ability for users to donate via PayPal to keep the program being developed.

Like all other WiFi site-survey tools, this program relies on the “beacon” information sent out by wireless networks at regular information and a low-traffic wireless network may occasionally show up on the program’s radar whereas a regularly-used network will exist on the program’s radar.

Data views

This program has a few different methods of visualising the wireless-network space that your Android device as listed below.

There is a Channel graph which, like inSSIDer, can show the relative strength of each SSID on the Y axis and channel positioning on the X axis. This can be useful for determining whether a wireless network is being swamped out by other networks or determining where to tune the wireless access point’s operating channel to.

Wi-Fi Analyzer Channel Graph

There is also a time graph which shows relative signal strength of access points over a time period. This can be useful for determining what happens when a certain network comes on line for example.

There is also an access-point list which lists each access point that the Android phone can pick up. Here, you are provided with the ESSID, BSSID, channel number and security type (including WPS capability) of each access point and can have this sorted by ESSID, channel,signal strength or security type (“openness”). This list can be grouped by ESSID and security type so you can identify multi-access-point networks. This view may not be accurate if you have multiple wireless routers in an area set to default SSIDs like “linksys” or “dlink” but working on different WEP keys or WPA passphrases.

Wi-Fi Analyzer Network List by ESSID

There is a Channel-rating bar graph which measures channel useability by the number of stars where the more stars that exist, the better the channel is for your network. You can also “set” an access point to this graph so you can compare channels to the one it is tuned to at the moment. Again, this would come in handy for tuning the access point for best operation.

Lastly, there is a Signal strength meter which allows you to measure the signal strength of an access point. This can be useful for locating rogue or interfering access points or simply to determine the coverage of an access point.

Wi-Fi Analyzer signal strength meter

There is the ability for one to connect to a network if the user installs the “WiFi Connector Library” either through the application or by visiting the Android Market. This can allow the user to “lock-on” to a network while monitoring other wireless access points.

It works well as a basic handheld tool for setting up a new wireless router or access point or keeping a small wireless network operating at its best. For businesses who run public wireless hotspots, this program allows them to assess their hotspot’s performance or find rogue access points (fake hotspots / evil-twins).

Usage tests

I had put the program to some usage tests with different wireless networks including my own and a wireless hotspot, This hotspot was a complementary-use service run by a small independently-run cafe whom I have been helping out with concerning its performance and keeping it “business-safe”. Here, I used the signal-strength meter to check that there was proper signal coverage over the public dining room and terrace area of that cafe. I also used the channel-graph view to determine if there are other access points or ad-hoc wireless networks able to be picked up in the cafe. Both of these functions worked well with assessing the hotspot’s coverage and quality-of-service.

As well, I used it in two shopping strips to assess how it and the Samsung Galaxy S Android handset that I was running it on could handle many wireless networks. It is able to identify each SSID and plot it properly on the graph and could cope with me walking into and out of particular access-point coverage ranges.

Limitations and Points of Improvement

For this application, the program could support “whitelisting” of BSSIDs against an ESSID so that one can easily know if the access point that is using your ESSID is really your network. This would work well with managing public networks like wireless hotspots by identifying rogue access points like the aforementioned “fake hotspots”. It can also work well with managing multiple-access-point wireless networks.

A “Pro” version, which would be sold for at an extra cost and wouldn’t have in-app advertising, could provide various extra functions like SSID whitelist management for use in optimising or managing wireless-network activity in particular sites or GPS support for “plotting” network coverage maps or the ability to keep standard log files for use with desktop software.

It is worth noting that this program is restricted to the frequency bands that the smartphone or tablet can cover and this is typically the 2.4GHz platform. At the moment, there aren’t any Android devices that can cover the 5GHz spectrum using their own hardware.

Conclusion

At last this is a program that answers my need for a cost-effective easy-to-use handheld network-survey tool in a popular smartphone platform. It can therefore be a good companion program to the inSSIDer program that I had previously reviewed on this site.

Introduction

I am reviewing the HP OfficeJet Pro 8500a Plus, which is the high-end model in Hewlett-Packard’s business inkjet printers. It is snapping at the heels of the previously reviewed LaserJet Pro CM1415 and its peers as a general-office colour workhorse printer and I will explain further why it is doing so.

Prices

Printer

Recommended Retail Price AUD$449

Optional Extras:

Optional high-capacity paper tray

There is no need to pay any additional fees to use the HP ePrint service.

Inks

The printer itself

Front-loading ink cartridges

This high-end printer has the ink cartridges installed up front in a similar manner to the Brother inkjet printers. It therefore avoids the need for users to lift a heavy lid when they need to install new cartridges in this unit; and there isn’t much effort needed to make sure the cartridges are in place; both of which I also find very important when this printer is used by older users or those with limited dexterity.  As well, this arrange also allows HP to use cartridges that have a page yield similar to that of their LaserJet printers.

Touchscreen control panel

Like the LaserJet CM1415 printer that I previously reviewed, this printer uses a touchscreen as its control panel. This provides for access to the common functions as well as the HP ePrint Apps; and can provide for a more intuitive usage experience. As well, it uses this display to show animations concerning maintenance and repair procedures like ink replacement, paper loading or paper-jam rectification when these procedures needed to be done thus reducing the need to have others train new users in these procedures.

It connects to the network via Ethernet or 802.11n WPA2 WPS Wi-Fi and has automatic wireless override if it is connected to an Ethernet or HomePlug network. A feature that I am pleased about and is becoming very relevant nowadays is that the OfficeJet can now work properly on an IPv6 network as well as a current-generation IPv4 network.

Walk-up functions

This unit has a very capable copy function that would satisfy most business requirements including ID-copy functionality where you can copy both sides of a small document like an ID card on to one side of one sheet of paper; a function I had first come across with the LaserJet CM1415.

But the feature that most impressed me with this printer was the quick duplex-copy function where it could copy both sides of a document on to both sides of a sheet of paper. I ran this printer on a duplex-copy “race” against my regular HP Photosmart Premium Fax C309a and found that this can copy both sides of an A4 page much quicker than the Photosmart could. This is more so due to the printer being pitched at the small office where throughput is considered very important.

This printer works with the HP ePrint cloud-based printing functions and is able to perform as the “network printing appliance of the office”. This functionality was able to work as expected especially with “email-to-print” and the print apps.

Computer functions

The driver installation can be a pain especially if a software desktop firewall takes too long to respond but, after I suspended the McAfee firewall software, it installed very quickly.

After that, it worked as expected for printing via the network. Windows 7 users will benefit from the tightly-integrated “Device Stage” presentation which has the “branded look” but without the excess baggage of the typical device driver / print monitor package.

You can scan to the PC but can also set the printer to scan directly to a folder anywhere on the network, which can be useful if you don’t want to have a computer running a troublesome scan monitor program in order to provide control-panel-started “scan-to-computer” abilities. You still have to use the HP software or the printer’s Web interface to determine the path where you want scanned-document images to end up at and this will work with the standard network file-transfer protocols.

Print Quality

As I have said before, this printer is intended to “snap at the heels” of an economy colour laser multifunction printer. This is demonstrated more so with documents that look just as sharp as those emerging from the HP Colour LaserJet Pro CM1415fnw which is a “general office” colour laser printer that I am measuring this up against. It doesn’t have the “laser shine” that is part of a laser printer’s output and may not be considered “up to snuff” for some business users.

The auto-duplex print mechanism is very accurate with the registration but still requires the blank top and bottom margins for it to work properly. Thankfully these are slightly smaller than on previous auto-duplex HP printers that I have reviewed before.

When this printer prints photos, the images look sharp and very defined but the colours don’t have the saturation that one would expect. It is similar to the picture quality that a laser printer would yield for a photograph; and may be good enough for quick hard-copy requirements. This may be a problem with printers that are “pitched” at business users because manufacturers don’t see don’t see mainstream business users printing out many photographs even though they may take pictures as part of their business life.

Limitations and Points Of Improvements

There are still a few shortcomings with this printer that HP could improve on.

Firstly, the printer could benefit from T.37 email-fax and T.38 real-time-fax endpoint functionality in order to make it relevant with other IP-fax solutions. This could be implemented either as an HP ePrint gateway service or as a local facility that uses “wizard-based” setup. I have raised this in relation to having this machine support a full-functioned fax service because of the impending arrival of packet-based telephony networks in most countries.

As well, I would like to see the implementation of flash memory functionality in a manner similar to the Colour LaserJet Pro’s fax functionality in this printer. Here, it could permit a proper “fax-vault” functionality for handling confidential faxes or permit improved fax archiving. This function could be taken further to provide fail-safe printing and improved fail-safe ePrint functionality.

The printer could Improve on photo-printing quality especially with the saturation. If they don’t feel it is appropriate to create an OfficeJet business inkjet printer with the high-quality photo-printing abilities of a Photosmart printer, HP could market-test and create a “bridge” printer lineup with the high-quality photo output, quick document output and cost-effect consumables.

Conclusion and Placement Notes

This printer is one that can put you in to a quandery whether to buy a printer like the HP Colour LaserJet Pro CM1415fnw laser or this model for use as a colour workhorse printer even though this printer is relatively cheaper to buy and run; and has some more functionality and media flexibility than the LaserJet.

If you simply want a highly-flexible general-purpose “workhorse” printer for that office, professional practice or shop; I would recommend this machine. On the other hand, if you are needing the speed and exact output capabilities of the colour laser printer, head for the Colour LaserJet CM1415fnw as a “general office” printer.

Articles

These French-language articles are both from France, which is one of the few countries which can boast a lively competitive ADSL2 or fibre-optic powered  “triple-play” Internet-service market. Here, these services are based around each service provider providing an Internet gateway device known as a Freebox, Neufbox, Box SFR or something similar, which I refer to as an “n-box”. These are connected up to an IPTV set-top box that is connected to the TV set and they are known as a Freebox Décodeur or Décodeur SFR or something similar.

My comments

The HomePlug that is a power supply unit

Previously I have been observing the developments concerning HomePlug powerline networking and have seen some HomePlug devices in an interesting form-factor. This form-factor is in the form of a single-box combination device which works as a power supply for a piece of equipment as well as a HomePlug-Ethernet bridge for that device.

These devices would have three cables

1. AC-voltage cable to plug into the AC outlet
2. Low-voltage cable to plug in to the device in order to supply power to that device
3. Ethernet cable to transmit data to and from the device and the HomePlug-Ethernet bridge in this box

A few companies like Netgear had tried these as “on-ramp” accessories for their routers but Free and SFR are taking off in their own right to use this as part of their “triple-play” environment where the TV set-top box and the modem are effectively part and parcel of each other in the home network. This is also achieved as a way of “idiot-proofing” these setups and avoiding unnecessary service calls.

Why not take this further

Bringing network printers to the HomePlug network

Quite a few network-capable inkjet printers that I have used or reviewed are using an external power supply rather than having the power-supply in the unit.

This is typically in the form of a power-supply “lump” similar to the typical charger unit that comes with a laptop. On the other hand, Lexmark and Dell use a power-supply module that plugs in to the printer and the AC cord plugs in to this module.

These setups could be used to provide HomePlug powerline networking capability to a printer as long as the printer has an Ethernet socket. This would provide a logical alternative to Wi-Fi wireless networking which is known to be unreliable at times.It is due to the fact that Wi-Fi it is based on radio technology which can be affected by metal furnishings, walls that are made of dense-material construction like double-brick or stone walls; or building insulation or double-glazing that uses metal foil to improve its insulation qualities.

On the other hand, manufacturers could simply integrate HomePlug powerline networking in to a SOHO printer design like the HP Envy 100 which has an integrated AC power supply without the need to create an extra socket for the Ethernet connection.

802.3af and 802.3at Power-Over-Ethernet – a perfect marriage with HomePlug

The 802.3af Power-Over-Ethernet standard and 802.3at high-power version of this standard uses the same Category 5 cable to provide power to a device as well as convey data between the device and the network. This is typically implemented with wireless access points, security cameras and IP telephones to provide a robust yet simple power-supply setup for these devices in business networks.

Here, a HomePlug-AV-Ethernet bridge could be integrated in to an 802.3af / 802.3at compliant power-supply module to provide a “one-cord” solution for connecting a device to a home network as well as powering that device from the AC power. The device would have to have an Ethernet socket capable of taking the Power-Over-Ethernet power; and this could appeal to a wide range of device classes like Internet radios, IPTV set-top boxes and electronic picture frames as well as the usual suspects like desktop IP telephones, Wi-Fi access points. Ethernet switches and security cameras.

Conclusion

This demonstrates that the use of power-supply integration can bring the reliable no-new-wires network that is HomePlug AV to more devices in a cost-effective design-friendly manner.

Telekom startet FTTH-Ausbau für VDSL in Potsdam – VDSL.de (Germany – German language)

My comments

The fat pipe is becoming fatter in Germany

Deutsche Telekom are intending to roll out FTTH (fibre-to-the-home) next-generation broadband into Potsdam, Germany. This is although there is a great penetration of VDSL-driven FTTC (fibre-to-the-curb / fibre-to-the-cabinet) setups in most of Germany, including this capital city of Berlin-Brandenburg.

They intend to have this fibre infrastructure pass at least 21,000 households in the southern and western areas of this city. Building owners will need to give Deutsche Telekom a permit to give the “go-ahead” for the fibre-optic installation work to start in their building, as would be required for most telecommunications works in these buildings; but this could be simply a formality as they realise the benefits of this technology for their tenants.

The deployment pricing will be similar to what has been called for Australia’s National Broadband Network where the installation will be free when the service is rolled out to the area but will cost more for installations commenced after the rollout.

As well, Deutsche Telekom do have a long-term intent to roll out FTTH next-generation broadband to Germany’s major cities.

Moving from FTTC to FTTH

What has interested me about this work is that it is an example of being able to move from an FTTC or FTTN setup with a copper run from a street box to the customer’s door; to an FTTH / FTTP setup which has fibre-optic all the way to the customer’s door. Thi is done while reusing existing fibre-optic cabling infrastructure rather than laying down new infrastructure.

Some of the FTTC or FTTN setups like a few of the deployments occurring in rural Britain are being designed with support for migration to the all-fibre layouts. So anyone who does want to advocate for a part-fibre part-copper setup for a next-generation broadband rollout would need to factor in a future-proof arrangement for FTTH/FTTP all-fibre setups down the track. As well, this approach can cater for environments where some buildings like offices or educational facilities could have an all-fibre rune but as needs change, other buildings could have the all-fibre run. Similarly, it can allow reuse of existing head-end equipment used for the copper deployment like DSLAMs on newer extensions of the part-copper part-fibre setup such as entry to new neighbourhoods for example.

So this setup means that even a part-copper part-fibre setup like an FTTC setup could benefit from higher throughput speeds by moving towards an all-fibre setup while retaining the existing fibre-optic backbone infrastructure.

Customers please note with these conversions

When these networks switch over from a VDSL2-based part-copper part-fibre network to an all-fibre network, you will have to move from a DSL modem router to a broadband router with an Ethernet WAN (Internet) port.

Some high-end modem routers will have a dual-WAN setup which uses an Ethernet port as a secondary WAN port and this may be in the form of a LAN port that can become a WAN port or as a dedicated WAN port. It is worth checking if your modem-router has this setup by referring to its instruction manual or manufacturer’s Website.
