• A thought: HSPA/LTE in unlicenced spectrum? Ideal for femtos?
• 2 days ago
• There's about a zillion frequency bands for 3GPP technologies these days - 700MHz, 850, 900, 1800, 2100, 2600, AWS, various Japanese ones, upcoming UHF bands and so on.
  
  But there's some notable absences - unlicenced 2.4GHz and 5GHz bands. The ones that WiFi and Bluetooth and a million other gadgets use.
  
  Sure, its unmanaged, congested, interference-prone.... but for short rang ...

• Mobile Web 2.0 and Power Management
• 3 days ago
• I've been playing around with some Web 2.0 services (Widsets, Yahoo Go etc) on a Nokia E71, and one thing I've noticed is that they kill the battery, as they keep going online looking for new stuff to pull down. Given that the device has a huge 1500MAh battery, the fact it can be depleted in a day (and gets pretty warm to the touch too) indicates to me that we've got a problem here.

I was inquiring about the new SonyEricsson C902 phone, and so asked them which networks it was available on. They replied that it was supplied in with either O2 or Orange contracts. (Interestingly, the CPW website also mentions T-Mobile, and it should be noted that the company no longer resells Vodafone).< ...

• Carnival of Mobilists on LBS

• While I'm turning into a big believer about location-based capabilities in mobile phones (GPS, maps etc), I'm much less convinced by the argument for monetisable location services.
  
  I can quite imagine buying a Nokia device which comes with 4GB of global maps built in, plus GPS. I can quite imagine continuing to use Google Maps on mobile, with its clever autolocation capability.
