France’s Free Mobile service to have free femtocells

Article

Iliad aims to boost Free Mobile service with free femtocells – FierceWireless:Europe

My Comments

In France, Illiad’s “Free” telecommunications brand is to use femtocells as a way of increasing its effective coverage. These are devices that provide  mobile telephony coverage within small premises, typically one’s house, but use the Internet service as the backbone to the mobile telephone network.

SFR offers a similar service for their “Neufbox Evolution” customers but this requires that they pay EUR99 per month for this service. Instead Free are offering it as a complimentary service to their “Freebox Revolution” customers. Both of the triple-play platforms will have the functionality integrated in their “n-boxes” which combine a network-Internet “edge” device (router) along with a VoIP analogue telephony adaptor.

For France, this will be seen as relevant for the mobile carriers in that country as they face an uphill battle against a strong NIMBY (Not In My Backyard) culture when it comes to deploying mobile-phone towers. This is more exacerbated as the junk science and fears concerning the side-effects of electromagnetic radiation are held as gospel in some French communities.

Issues that can affect current femto implementations

A limitation I have observed with these “femto” implementations is that they will be designed to serve up to four or five handsets, which may be enough for a household. But for a country that has the cafes and brasseries at its heart, there needs to be reference designs for femtocells that can work in a similar manner to a Wi-Fi hotspot service. Here, the device could support around 10 to 15 concurrent users. The service could support multiple-carrier traffic and provide the host carrier or even the business’s owner with a service bounty for customer’s voice minutes that pass through the femtocell.

Similarly, there can be the issue of assuring coverage across the property for a femtocell setup. It may be of concern with larger properties in areas of poor mobile coverage or properties that have radio obstacles like thick brick walls for example. This could be rectified by establishing a mechanism for “multi-femto” arrangements where the same backbone can serve two or more femtocells with proper seamless handover.

Other technologies

Of course there are other technology setups that may work instead of the femtocell. The classic example may be the use of Wi-Fi technology with EAP-SIM authentication and VoIP call-provisioning systems to provide “indoor” mobile-call service. This will typically require the phone to have integrated Wi-Fi functionality which most smartphones do have; but support seamless handover, quality-of-service and accounting between cellular and Wi-Fi networks.

Another issue that will affect this setup is current-generation Wi-Fi transceivers that are integrated in smartphones is energy use when in full activity. Here this will affect the mobile phone’s battery runtime and typically cause the phone to require charging more frequently. Most likely this will be rectified in the upcoming generations of Wi-Fi transceivers available for these devices.

Conclusion

The French femtocell services offered by Free and SFR are worth examining as far as private femtocell and “quad-play” (TV, telephone, mobile telephone and Internet) services go. Here, it would be worth examining the technology and its relevance for mobile-telephony service goes especially where the NIMBY culture thrives; and identify the real problems where it can run into when using it to augment these service in the public and private realms.

HomePlug now integrated in the power supplies for “triple-play” equipment

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.
