Modelling cellular system

on Tuesday, December 7
In my previous post, I uploaded a snap shot of GUI version of my simulator. Am interested in developing a professional multi-cell deployment simulator tool with the following features. The targeted end-user client would be an cellular operator, vendor, network deployment study team or non-profit organization for generating whitepapers.

Deployment trends in cellular communication will take a new paradigm shift. Unlike the sectorized deployment of narrowband systems like GSM, the broadband systems like LTE, WiMAX will do frequence reuse deployment. The primary service on these networks are packet data service. The goal would be to provide any-time UP kind of data-pipe, similar to a dedicated broadband DSL connection. Whether the packet data is short time (like Social Network, Messenger updates, or Push POP notifications) or long session connections like watching streaming video (iptv, youtube, widevine ) or uploading live video ( justin TV, ustream). And a reliable connection on-the-go (Dont want a banking transaction query or link to break).  This requires to have sufficient coverage to provide a minimal reliable throughput link. 

Mobile Broadband in India

"A comment that I had written on a discussion regarding mobile broadband in India on BWA spectrum"


Personally, I believe there is first need to drive the need for BROADBAND for common man. Probably the operator will have enough time to study the market after the 3G deployment. India has wide range of user-base. Dongles are not the business for common man. Who needs "data" and what goes on "data" will be drive the mode of deployment of BROADBAND.

Few comments on the technical flaw in the article

The first statement itself is technically incorrect!! "Wimax-LTE (Long Term Evolution, the fourth-generation mobile technology invented by Qualcomm Inc of the US"

Author of the article should consult some wireless technology person..

a) Wimax-LTE are two different technologies..

b) Qualcomm did not invent LTE!!

LTE is colloborative standard developed by the 3GPP (considered to be leaded by EUROPEAN countries)

c)LTE is based on OFDM not (CDMA for what Qualcomm is better known for)

d) OFDM has been more than 40-50 years and 802.11 is based on OFDM techniques

Telecom India: So much rubbish on LTE/WiMAX in Media

Check out the recent blog of a friend on the "mis-leading" information of the media on the wireless spectrum auction and the technology itself.
