Re: Universal phones

said by podstolom:

Nope, the Nexus isn't there yet. A WCDMA Band I, IV phone (TMobile USA/Europe) is still different from a Band I, II, V (ATT/Europe) and still different from a CDMA phone (Verizon/Sprint).

They should start bundling Radios and SIM cards into modules that can be swapped out by carrier or else build one big multi-band multi-protocol monolithic radio for universal connectivity.

Incidentally the WCDMA (UMTS/HSPA) standard has 16 bands. And CDMA has at least 4, and Cox is putting out 1700 MHz CDMA soon (that's Band IV/AWS) and there's 700 MHz for LTE, and 2.3, 2.5, 3.5 GHz for WiMax, and.....oh yeah, unlicensed WiFi stuck in the middle at 2.4 Ghz.
The fact that VZW and Sprint chose to use a technology different than the rest of the developed world isn't Google's fault.

While I only count 14 UMTS bands, a relatively capable worldphone "only" needs 5 of them for worldwide 2g/3g support. 850, 900, 1700, 1900, 2100.
