When do you think we will have high speed Internet

  1. Sep 24, 2004 #1
    When do you think we will have high speed Internet (>10MB download rate) everywhere (even on top of mount Everest, the artic/antartic)? Another 20 years?

    What is the roadmap for internet in the next 10 years? :cool:

    Personally, I think physical cables will phase out. I like wireless, everyone else does, and it's just as secure as a standard physical network (perhaps even more secure given the intrinsic encryption features it possesses). Another reason I think wireless will dominate is the simple fact it's easier to build and maintain a wireless network. Would you want to run a CAT5 cable up Mount Everest? I don't think so.

    I would want to run CAT5 if it was still quicker
    Its all about speed
    once they get to the point where people can dl full dvd in less than 10 seconds with wireless than people will go wireless... and cable will still be around if its is faster

    speed is the name of the game

    Tom, the fastest wireless connection is currently at 54mbs. That's not bad considering standard CAT5 runs at 100mbs (gigabit isn't bad, either). Transferring a DVD in 10 seconds, as you said, is pretty relative. It depends on a number of things, such as whether you're transferring over a local network (in that case, a CAT5 cable would be much faster) and over the internet (which in such case it wouldn't make a difference).

    By the way, not even gigabit ethernet can transfer a DVD (~ 4.3gb) in 10 seconds.

    Edit: To add to the discussion, you'd be fine playing a DVD over a wireless internet connection. Considering every second of playback and the total DVD (the whole DVD wouldn't be ~ 4.3gb, anyways, remember the extra features that usually come with movies), around 54mbs would be plenty to watch a DVD.

    We can already route traffic at ridiculus rates, the fiber backbone running throughout the world are all over Gigabit rates ( http://www.ams-ix.net/about/stats/index.html Amsterdam Internet exchange)... The problem lies with the "last mile technology" we use to access ISP's.... As the protocols we use for the last mile mature and the algorithms used to put the data on the wire become more efficent, you will see last mile technologies become fatser and faster...

    Cisco have already produced the "BFR" which can route traffic at over 92Tb/sec ( http://www.cisco.com/en/US/products/ps5763/index.html )... There "vision" is that Data and PSTN will merge as VoIP becomes more prominate, thus the "Internet" will become used for Voice and data thus more data will traverse, and end users like me and you will demand far greater speeds from our lastmile technologies....

    In Northen Europe, it is not untypically to have xDSL at over 10Mb already... So the technology is there....

    As for FWA (Fixed wireless access, which is not the same as WLAN) it is no where near as secure as wired access... thus if you use this for the last mile technolgy you should use IPSec or some other encryption protocol...

    The "Roadmap" for the internet in IMHO is that Data and voice will merge (if sprint etc allow this to happen :-) Lucent has already jumed on the bandwaggon with the IP voice solutions under the name of avya), last mile technology will increase in speeds through exsiting copper and co-ax tenologies....

    On Everest you can already download at high rates (via sattalite)...

    My 2 pence :-)

    OFDM 360 Mb/s wireless communication

    OFDM the furture of wirless communication

    http://www.siemens-mobile.com/cds/frontdoor/0,2241,hq_en_0_67687_rArNrNrNrN_2%3A3,00.html

    "At the “Mobile Internet 2010” forum held by the German Ministry of Education and Research on September 14 and 15, Siemens presented the latest results from its mobile communication research for the first time to the general public. On a test system, videos and music as well as a Microsoft NetMeeting conference were transmitted in wireless mode at data rates of up to 360 megabits per second (Mbps)."


    How it works:
