ARM introduces new 32bit CPU
ARM is known for it's big processors that are licensed to all and sundry for inclusion in products like the newly announced Apple iPad3 which uses an A5X CPU (dual core CPU cores running at 1GHz with a 4 core GPU) and many other licensees including Qualcomm for their Snapdragon range etc.
ARM are also big into micro controllers that sit in the myriad of deices that require some form of control (toys, white goods, dumb phones etc), these also tend to be very low power devices. ARM's latest version is the Cortex-M0+ or Flycatcher which uses 9uA/MHz on a very cheap to fabricate 90nm process (Intel's latest CPUs are all on 22nm substrates) and use around 1/3 of the power required by existing 8 and 16bit CPU architectures.
The Cortex-M0+ is software backwards compatible with the older Cortex-M0 range of processors so all existing software can be used.
This is a potentially huge market and Ericcson estimate that there will be 50bn units with these types of processor in them by 2020 - which will make up the internet of things.
ARM will also offer low power Bluetooth and other connectivity products which can be paired with the processors.

Low power GSM goes live
Mapesbury Communications also known as MCOM today made their first GSM call. Last year they won a GSM Guard Band license (1 of 12 licensees).
The set-up used a pico-cell BTS (basestations) connected to a soft-BSC (basestation controller) which in turn was connected to a soft-MSC (mobile system controller) and then used SIP to their VOIP servers which connected to the telephony network.
It all seemed to work rather well.
The Mobile Network Operators (MNOs) do not seem to be keen to allow them to interconnect with them, one even refusing to switch their Ofcom allocated number ranges as they're "not a real mobile network". Ofcom may not be too happy about it. In the meantime though they can offer private GSM services, just without roaming to the existing MNOs.
It seems plans will be to allow "free" calls to other MCOM users and any SIP users. Since connection to the PSTN isn't free, any PSTN calls will be charged for. This will also be true for calls to MCOM mobiles.
MCOM may set-up GSM "bubbles" or clouds, like current WiFi zones.
Low power GSM licensees could change the way people think about mobile pricing which is probably why the current MNO's are worried.
