Getting set for WiMax

THE FIRST WIDELY AVAILABLE WiMax service should hit South Africa's streets in August if Wireless Business Solutions (WBS) has its way. Last week WBS announced it was going to start trials with a WiMax service in Gauteng, Cape Town and Durban.

"Those would be a guaranteed bandwidth link with either 128Kbps or 256Kbps, or a slightly faster, non-guaranteed service at 256Kbps and 512Kbps,".....

128Kbps or 256Kbps !! Am I missing something?

WiMax is envisioned as:
The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformance and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL"

This guy is clearly missing the VISION of what WiMax is set to achieve....!!!!
KEY WORDS
wireless broadband (at thise time and age anything below 512 can not be considered BROADBAND, in 2001 perhaps not today)
alternative to cable and DSL (Alternative means it does very similar to as the other option)

@DblD : my opinion (and some industry knowledge) is that they do not have sufficient backhaul / transmission bandwidth to sustain bandwidth greater than 256Kbps for each basestation. Not yet anyway. Once vodacom's fibre rings are up and running, I am sure they will start to offer quicker services. Our tests have concluded that a basestation can do at least 45mbps.

ditto

And my criticism is aimed at the sensationalism brought forward with reference to technology that implies an service offering as it was intended... not some bastardized implementation due to restrictions of the back haul....

It is like a anticlimax to release a BIG news of WiMax offering with restrictions, whilst the lacking back haul capacity (the Vodacom fiber rings if i understood you correctly) are announced to go live in a week?!


I put this question to the fore,
What is the purpose of implementing WiMax when the back haul is simply capable of sustaining ISDN load?

You guys are forgetting that iburst only have 14mhz to work with.
That could be why they can't offer anything above 1mbs

I believe they got an extra MHz, to allow for 3 x 5MHz sectors per BS configurations. As you say, not much you can do with 5 MHz per sector, current max without MIMO ~ 13Mbps per sector.
 
Some might have missed the "guaranteed" bit in the WBS offering. All wireless services currently available are best-effort (Neotel, Telkom, VC, MTN, Sentech, etc.).

According to the engineers I've spoken to this is not only a world first but added a fair amount of complexity into the network to be able to run a 'diginet-like' service over wireless.
 
Well WiMax is bound to fail in SA should WBS / iBurst be involved... (Think they will soon be following the Sentech route, if one is consider their current service delivery.)

They have made such a mess of HC-SDMA service with more and more users giving up on the orange bubble.

After operating for more than three years, they still seem unable to successfully provide a stable and efficient service.

Either backhaul capacity is not available, towers are overloaded or incorrectly configured that the access resembles dial-up connectivity instead of broadband.

I would think twice signing up with this company, if you have a look at their service record and the amount of complaints lodged against them.

The only hope is that Vodacom will have a controlling stake in the configuration and maintenance of the network. If this is not the case, the service that is to be provided by them is doomed for failure...

"iBurst will act as a service provider for its WiMax service, along with Vodacom Service Provider, at least for the trial period."

What the use if they use iBurst & Vodacom. Just gonna be another type of package with the same prices or even more expensive. If i remeber correctly WiMAx is supposed to be a cheaper way of delivering the data to the client.
