    Lol, CDMA is gonna be around for awhile yet, but it does explain the reluctance of embedding WiFi in the some of the handsets being released imo.

    Just a fyi, somewhere in Atlanta a a carrier is running a test of the WiMax network, the phone models are unknown and the carrier is being kept secret too, on my limited access to this info I know there is at least one blackberry involved, note that this is totally different to the wimax article published in BGR and Engadget recently.



    Now a question for you network gurus, if we now what's the equivalent to 3G in us carriers, what's the equivalent to 3.5G???

    Or even better what the hell is 3.5G then?
    The reason I'm asking is because in my country there is a carrier that offers 3G and one that offers 3.5, both GSM.
    And the CDMA is 2G.

    I will comment then of course let cruz fix my mistakes 3.5G will be what AT&T is rolling out and the end of the summer which is their 7.2MB network. This is something that the iPhone will be access once AT&T turns the switch one. I believe that is called HSPDA.

    One of the reasons for the 3G standards war was the requirement to pay American company Qualcomm royalties on patents for several techniques necessary for a mobile CDMA system. LTE is not CDMA, so those royalties are avoided… but it turns out that Qualcomm filed or has purchased many patents that underpin LTE. Additionally, since LTE phones will have to be backwards-compatible with 3G CDMA networks, Qualcomm sees “no impact” on patent royalty revenue for the first ten years of LTE development according to COO Sanjay Jha.

    The 3GPP Technical Report 25.913 contains the detailed requirements specification for LTE. The system architecture, in Technical Specifications 36.300 and 36.401, is simplified to two principal network elements: evolved Network Base stations (eNBs) and Evolved Packet Cores (EPCs). eNBs communicate with EPCs, with each other and with user equipment.

    LTE is slated to become part of IMT-2000, the 3G “standard”, so in a strict standards committee environment, LTE would be called a 3G technology. An updated version, 3GPP release 10, which might be called LTE-Advanced, is expected to be submitted to the IMT-Advanced standards committee, which would cause those standards committee members to declare it officially a 4G standard. Everyone else will refer to LTE as 4G from the start.

    Clearwire launched in Atlanta June 16, 2009 Looks like they will be starting with the mobile VoIP handsets, then move on from there. The only WiMax device I know of at the moment, would be the Samsung Mondi.

    I'll rely on Cruz to confirm, but in my opinion for CDMA Rev A is 3.5, since it was the only released (phonewise) upgrade to EVDO, and HSPA is for GSM, since its a speed increase from HSPDA.
    No matter where you go, there you are

    If your not already, you'll soon be seeing advertisments for 3.5G, 3.7G modems and routers. Looks to be more of a marketing ploy than an actual technology. 3.5G is a beefed up variant of 3G network technology capable of delivering downlink speeds of up to a theoretical maximum of 7.2Mbps. Typical speeds achieved are between 800Kbps and 3Mbps.

    Yeah I googled HSPDA and HSPA to find out what the diff was and the HSPA sites all mentioned that 7.2 mbps, and recommended it over HSPDA.

    Yes, It all looks good in theory, the stars and planets will have to be aligned just right to hit 7.2 on a downlink. Expect, on a good day 3.6mbps. I wouldnt rush out and buy a new device that boast of faster downloads. The lowered latency will be the most notable difference.

    Wow, Cruz, thanks for the info! Mmmm, makes me want to stay month-to-month if indeed this may happen possibly late 2010. I was thinking maybe going with the Storm 2 or Tour, but don't want to be locked into a contract. As long as BBC keeps the hybrids rollin, I think I will wait it out to see what actually happens.

    No problem Crickee, you have the right idea, just hang tight and let the carriers deploy the 3.5, 3.7 and 4G. I wouldnt be suprised to see 3.75 3.8 being advertised before all is said and done.
