WiMAX Preamble Planning

Hi All, I am going through the technical literature for WiMAX Preamble planning using Planet. I am confused with the following:Questions:1. Preamble is used for the channel estimation at the subscriber, this means the BS has some channel information on the basis of which initial channel estimation is done. Otherwise the CPE sends channel estimation in CQICH. Kindly clarify this. 2. The WiMAX standard defines a total of 114 preamble indexes each consisting of an integer between 0 and 113. Each…See More

"Hi, at the moment I'm more related with LTE strategy and spectrum studies. I'm already forgetting all the bits of the WiMAX physical layer. anyway I can try to provide little help, just post your question"

Hi Hassan,

I see you are seeking info on WiMAX network optimisation tools. We at ProVision Communications have developed advanced software algorithms around our ProPhecy prediction engine that has been specifically developed for WiMAX network optimisation. Our optimisation tools can also work with third party prediction data.

The ProPhecy optimisation tool selects the optimum number and locations of BS sites from a user supplied list of obtainable sites. The optimisation takes into account the distribution and traffic demands (including QoS) of various types of users, the costs associated with obtaining and running each BS site, the desired coverage and capacity targets, charging schemes (for revenue optimisation), radio resource allocation parameters, load balancing, and several other factors. Predictions for each potential site are obtained from the ProPhecy prediction engine, but can also be obtained from other third party tools and/or measurements. Optimisation considers traffic flow in both uplink and downlink, and determines the required backhaul capacity. The optimisation produces a ranked list of solutions, with ranking based on a choice of metrics e.g. total coverage, total aggregate throughput, total network cost, total projected revenue, amongst others.

Hope this is of help to you and if you require more info then you can reach me at:

george.green@provision-comm.com

Best regards, George Green

Hi Hassan,

how are you?
Tell me your email address so that I can send you some QoS documents.
Regards.

Thanks Hassan. I'm always glad to help when I can.

Are you building in Urban or Ruralareas? Fixed or Mobile? What kind of capacity do you plan on offering?

Wassup Hassan??

Hi Hassan,

sorry for the delay...
Actually I don't have much experience in the RF field, but if you want some help with the MAC layer or QoS mechanisms I will be glad to help you.
Regards.

Hi Hassan :) If you are going to build the wimax network in Georgia as well, we'll definitely compete :)

Sorry, I can tell you nothing about this until we launch our services :)

Okay, we'll see who is going to rule :) we'll be number 1 :)
