  1. 100Mbps over copper

    Posted 23 Jan 2008

    Saw this article in this week's Business Express. Neat stuff.

    Extra-wide broadband technology for Vision 2020

    Quote

    Cooper Ramp Technologies under the management of telecommunications expert and scientist Dr. Boysie Goolcharan has come up with a revolutionary technology called "extra-wide broadband" which the company says will take Trinidad and Tobago to Vision 2020 in the field of technology.

    Dr Goolcharan and Pranesh Maharaj, executive chairman/CEO, JP Parker Limited (public relations and project management consultants for Copper Ramp Technologies) sat down with Business Express last week to discuss the dynamic of this cutting edge technology that was patented by Goolcharan in the United States to be applied globally.


    This is the really interesting bit right here:

    Maharaj explained that the future of high-speed data transmission is available in Trinidad and Tobago today with 100 megabits per second upload and download speeds already available.

    The patented technology enables TV quality, full motion video, audio and data in real time on unshielded twisted pairs (UTP) quality copper cables.


    I guess they'll have to pull the copper out of the cold, dead hands of TSTT. ;)

    It still seems to require a fiber backbone though (shouldn't be that big a problem in TSTT ever decides to implement it). The bigger deal might be getting bandwidth into the country, via more numerous/upgraded submarine cables.

    Quote

    He explained that CRT's extra-wide broadband allows for high-speed data transmission in both directions (up load speed = download speed) on regular copper telephone cables. It is viewed as the ideal last mile solution, because it allows ultra-high speeds using the twisted-pairs copper telephone wires.

    "If the telephone backbone is upgraded to fibre optics, the bulk of the data can be carried on fibre-optic cables, up to the junction box on the curb; CRT's extra-wide broadband will interface with fibre-optic cables and carry the signals to the user on the wires," Goolcharan added.


    Good read.

  2. Switching DNS Servers?

    Posted 19 Oct 2007

    Hi guys! I've been having some issues where my connection just seems to 'drop off', but not completely. Some sites would work fine (stuff I had just visited), but it refuses to load any new sites (instead, the browser throws up the nifty "server not found" message). Indeed, even email works, but not new webpages.

    So, that sounds like a DNS problem, right?

    ----
    Anyway, let me get straight to it:

    1. Has anyone else had experiences like this? Does changing the preferred DNS server from default (TSTT's) make the connection more reliable?

    2. Is there any downside to using the OpenDNS.com servers (208.67.222.222 and 208.67.220.220)? I notice the servers are pretty far away from us, so wouldn't that incur some speed loss vs TSTT's local servers?

    3. Where should I change the settings? In Windows/OSX, the router (linksys wireless :( ) or my speedstream modem?

    4. Other than OpenDNS.com, are there any other alternative DNS servers I should check out?

    [I'm using TSTT's non-blink DSL, of course].

    Thanks in advance y'all.
