Uh, the only way you can do this is with a hardcore constellation of VLEO sats with stupid large antennas, something similar to the proposed sat design by Tethers Unlimited which builds it's antenna in space.

Neptune - Expect Change
Make the phone core be the bracelet, and the display a secondary wireless screen. Splits the power consumption roughly in half, does allow the possibility of using other larger touchscreens. Wonder if it ends up being a miracast style device?

ESD CryptoPhone
High security Android smartphone with what they call a baseband firewall, allegedly a retooled Samsung S3 selling for $3500. But the "baseband firewall" feature's biggest point, is a feature old Nokia 2G dumbphones had standard. Which was to show a closed lock icon if GSM encryption is active, and an unlock icon if it was disabled. Kinda sad that current android phones (and iPhones) don't warn you if the baseband is running in unencrypted mode.

Has some sort of mechanical docking mechanism built into the pocket/sleeve inside to connect and charge your phone (apparently device specific so you have to buy the right purse). The purse bag itself charges its battery via inductive charging (Qi?) it seems.

China mobile OS takes aim at smartphone giants | News | PC Pro
Alibaba's take on the hybrid hetereogenous cluster model for cell phones, offloading the heavy work to the server. They seem to want to push almost everything to the server, but until cellphone network coverage is good enough to cover no/low bandwidth zones, I don't think that's viable since that approaches a full thin client model. NTT's hybrid thin client model with synced low/high power android OS pairs keeps a viable local OS and apps while still pushing the big work to the cloud.

Naratte, Inc.
Neat trick of using mobile phone mics/speakers to transmit ultrasonic tones containing data tokens for poximity payment or security token exchanges for pairing. Almost zero new hardware on the phone (compared to NFC), since it is just reusing the audio features. Implementing on the POS is just a mic/speaker combo, rather than a full energizing NFC reader terminal so there are cost savings there too. Probably most POS systems already have the necessary underlying audio codec hardware in their SoC's anyways, such the cost there is adding the mic/speaker.

Vodafone truck can recharge 2,000 devices at once, is coming to an Isle of Wight near you -- Engadget
This is pure marketing genius for large outdoor festivals. The only way to make it better would be to integrate a picocell/femtocell station into the truck to lower transmit requirements for phones near the truck (thus reducing power consumption), but connecting to the phone network backhaul would be nontrivial (WiMAX? Microwave? Shotgun modem setup to aggregate/trunk calls to the next nearest base station with a directional antenna?)

Fujitsu to Launch Mobile Service for Diabetic Patients -- Tech-On!
Almost there. Dedicated cable is dumb, but understandable since the bluetooth health device profile stuff is not ideal, and this is marketed towards elderly diabetics, who are likely to already use these "Rakuraku" simplified feature phones and need something simple. Now if that bloodless glucose monitoring sensor technology finally comes together, and linked with a bluetooth radio, diabetics can avoid the hardest part about glucose monitoring; that stabbing the finger business to draw blood that really hurts.

Constant connection
Interesting research about cellphone movement path prediction to optimize network connection handoff and connection power control, using the mobile unit (in this case a cellphone with GPS) to advertise to the base station its location so that a base station/cell network that is multi tower location aware and proactively handoff signals to other towers. This would be good in travel corridors such as public transit and highways where people are moving a lot. This would go hand in hand with that recent hardware announcement of base station tower hardware that offloads baseband calculations to a central datacenter, turning the entire cell network into a managed distributed antenna array, which by design will be at least location aware of its towers for cooperative forced handoff for load leveling in multi tower visible LoS situations. Sniffing the location information of endpoint devices, which is currently government mandated, to enhance the overall network capabilities is a logical step.
