cannuck, re bluetooth Not so fast. Ericcson, IBM, Intel, Nokia and Toshiba were the five founders. Microsoft, 3Com, Motorola and Lucent all came on-board after. Problem is, by using Bluetooth, you are bound by the requirements of the SIG. In addition, Bluetooth operates on 2.4 GHz, which is the same frequency that the French military uses. Big boo-boo. The French military came first. although France is but one location, Bluetooth's ultimate applications due to its spectrum repositioning has been a problem. however, now you can piggyback some bluetooth applications utilizing 3g spectrum as long as a 3g compliant interface is present. SIG's rules were supported by all to prevent interference bw carriers. anyway, the ITU developed TDD as an all encompasing air interface technology which can incorporate Bluetooth functions within its stack, with its own robust format and plentiful spectrum. TDD is bimodal with FDD (FDD is DS-CDMA or WCDMA and MS-CDMA or CDMA2000 3g interface). Bluetooth may not ultimately last; but TDD will - the UK carriers, ALL five of them that spent $35 billion on 3g spectrum, just signed up for 5mghz each of unparied (TDD) spectrum. So, "it's use it for TDD or lose it" (British law). TDD technology is principally owned by Nokia, Siemens, and IDCC; there's a few other SDRs too. Handhelds are great for Japanese and probably other densely populated countries. Why? Because space and privacy are at a premium. There are far more handhelds in Japan per capita than North America, not because of "high traffic corridors" or "densely travelled geographies", but because of the make-up of social dynamics. You can punch in a message on a handheld while riding a crowded subway train in Japan, and no-one will know what you have typed. Pull out a laptop, and you won't even find enough physical space to open the thing up. this represents some of the reasons why Japan is moving quickly to 3g because their current 2g spectrum is tapped out. i beleive the reasons for NorthAmerica moving to 3g, however, will differ from those in Japan. Europe's reasoning for 3g is mainly revenue based. the falling Euro is actually helping spur the Europeans toward 3g, not away from it. MichaelDell also wants to attack 3g upgrade properties (GPRS) as quickly as possible with product applications for the laptop. The applications are enormous
