    Five Things You Need to Know About LTE

    1. It really is fast. TeliaSonera, the Swedish carrier that in 2009 launched the first major commercial long-term
    evolution (LTE) service, delivered an average downstream speed of 33.4Mbps in informal tests last year. Verizon
    Wireless, which is using narrower spectrum bands, estimates that even on a fully loaded network, individual subscribers
    will get between 5Mbps and 12Mbps downstream and about 2Mbps to 5Mbps upstream.

    2. It has less delay. LTE networks have lower latency than earlier cellular systems, so packets are less delayed. This
    makes a difference when timing is important, such as when using voice over IP, streaming video or working on a virtual
    desktop. Verizon claims LTE cuts latency in half compared with its 3G network, and says LTE subscribers are seeing
    latency of about 30 milliseconds.

    You slept in again Rod!
    Did you bring a late note?

    Nope, YOU slept in and I commented on your post as soon as I saw it.

    There were other posts from me well before that one commenting on your post in here alone.
    Dont need one.
    This is no laughing matter, and dont you forget it.

    i.e. somewhat less than ADSL2 in the real world. Thats great if you are
    out and about with a laptop or iPad, but a bit light on for serious work.

    Theres nothing in this article that defines what a fully loaded
    network is .
    How many customers per Basestation.
    Wireless is a shared medium and the thruput is ultimately limited by
    customers per base station. and in reality , maximum thruput isnt
    limited by the technology, but by tower congestion.
    ie Carriers oversubscribing their networks.
    Ultimately, its economics that dictates maximum thruput, not the
    technology.

    Can you be more specific?
     
  11. I'm kinda shocked you're the only one who mentioned this.

    Under test conditions, anyone can make any product go like it shines
    out of god's arse.

    Under real-life conditions, where it's deployed to many people, it's
    paid for out of a limited budget, and is used with sometimes entirely
    unpredictable conditions, environments, equipment AND end users, all
    bets are off.

    Yeah, I used the Optus speed test from here (Germany) to the
    Sydney server on two occasions. Once I got a download speed
    of 6 Mbits/s, the second time it was only 550 kbits/s.

    Don's article did.
    Nope, its easy enought to test that too.
     
  14. But that's part of the problem. They're selling this to us and quoting
    figures before it's even been installed.

    OS installations are a better guide as to how it's going to go, though
    from what I remember, the early tests were touted as brilliant to
    everyone except the few end users who were testing it.

    Thats a lie. There is plenty of LTE installed world wide.
    Yes, just because they arent in this country is irrelevant.
    Irrelevant to how it actually performs with many using it at once.

    Only if you know all the conditions. Some countries have comms that make
    ours seem absolutely magnificant and that includes many places in the USA.
