@ Washington, we can afford anything :-) we went to Maranda you know ;-) @ aki, all those HSXXX technologies are some mutation of 3G. The air interface remains the same, you do not change the node b, or the spectrum or the multiplexing technique. I'm not really a radio guy so I unfortunately don't know the details on how they achieve this, but I know if Safcom or Airtel or Orange wished to do 42 Mbps today, they could certainly achieve it with some parameter and license changes on the existing 3G networks. Now 2Gis different from 3G and is different fro 4G. You need some serious upgrades to transition from one to the other. Either on the core or on the radio network/air interface. Maybe someone can shed some light on how the various rates are achieved.... On Wed, Feb 29, 2012 at 11:42 PM, aki <aki275@gmail.com> wrote:
@John Doe, some comments from me, slightly off-topic. IMHO :-)
I tend to disagree with you that all 3g networks are the same because newer technologies means better usage of the frequency spectrums and multiplexing techniques. However, unfortunately at the moment I do not have the time to do further research into the various HSXXX technologies, else I'd have done a write up on it.
I'd like to invite Telco or Mobile network engineers on all networks to be part of this discussion on the HSXXX standards. I believe on Skunks its not an issue of who you are or where you work ( so there is no need for the disclaimers such as "this is my personal view and does not represent the view of my employer etc etc)", as long as you are a technologist and can comment to improve knowledge and discussions, we will go a long way. Technologists need to take a leaf from PS Dr Ndemo. Does anyone ever ask Dr Ndemo about anything thats going on in e.g the OP or govt sectors?
Similarly, when I communicate onlist with people whom I read are with e.g. Safaricom, it would be pretty childish and immature of me to ask them about internal Safaricom affairs.They are technologists like many on this list, and should not be denied the right to openly communicate just because they work or are associated somewhere. If we are denying technologists the chance to communicate because of their professional commitments, this amounts to discrimination as an open forum.
I believe the floor is open to technologists to debate the HSXXX technologies and give their views.
Over and out for now.
Rgds.

Actually, Safcom, Orange and Airtel can all do 42 Mbps if they so wished. But would users afford the modem?:-)
Its all marketing on Airtel's part.
