This is going to be the year of the Femtocell. At least that’s the message that the industry is putting forward. Next month at the Mobile Congress in Barcelona, the industry is likely to be united in singing off that particular hymn sheet. However, an RFQ from a network operator that was put out just before Christmas suggests that opinion might not be as solid as the industry hype portrays. Rather than looking for femtocells, this particular operator was contemplating the deployment of small 802.11 access points around the home, connected together and to the broadband line using HomePlug. The implication is that instead of providing a personal 3G cell in the home to compensate for their lack of indoor coverage, they’d prefer to flood it with Wi-Fi. It’s an interesting approach…
This year will see the arrival of a new short range wireless standard that is set to revolutionise the way that devices are made. That’s not a new claim – I recall it being made for Bluetooth, Wi-Fi, ZigBee, Home-RF and DECT, amongst others. Some succeeded massively, some struggled on and some failed. This year sees another technology join the fold and I’m confident that it will make a bigger change that any that has preceded it.
The technology I’m talking about is called Bluetooth low energy. Don’t be fooled by thinking it’s a variant of Bluetooth – that would be a mistake. Although it’s part of the Bluetooth family of standards, and designed to coexist within an existing Bluetooth chip, it’s a totally new standard, designed from the bottom up to fulfil a new set of requirements.
Those requirements are to enable a new generation of products that can connect to mobile phones. It covers everything from fashion accessories, watches, fitness and medical devices to office and security products. The essential thing is that they can be low power, low cost devices that only need to send small amounts of data. That allows them to be run off batteries that don’t need regular charging. In fact most of them will run for years on single coin cells.
As well as connecting to your phone as accessories, they’ll also be able to use the phone to send their data over your mobile network to a remote web service. That’s where Bluetooth low energy becomes really powerful, as it allows your mobile phone to act as a gateway.
