Mobile Network Cell-edge Simulation

Some time back, I had simulated the aspect of cell-edge scheduling in a wireless cellular network. The snapshot is embedded. I used Qt based library for the visualization and itpp library for the back-end to simulate the signal processing, schedulers, CDMA base-station, receivers.

The GUI uses a dynamic webkit to present Google Map, with labels and other locations. Above the Map layout, there are graphical elements in different colors. The centre of circle, with three sectors in each cell. The different shades (other than BLUE) represents the SINR of the UEs.  Due to the wrap-around model one may notice that a UE at one of the cell  is being scheduled with a base-station too far from that cell.

Small cell deployments in next generation wireless technology

In my opinion, this is going to drive the new deployment strategy. LTE is purely a data aimed technology. Compared to earlier wireless technology 3G,GSM, cdma2000 which primarily was focused on providing voice.

Think of voice, which consumed the a good and reliable amount of wireless resource (time (GSM slots) or codes (cdma/wcdma long codes)) for short duration of time. While when one is talking about packet services. One does not want to "dial-up" a data session. Its an always on connectivity when you are connected to through a 4G-MOBILE terminal. The "dongle" based access is a different case.

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.

Old players of mobiles phones like nokia, samsung, blackberry have been enjoying their good share of market since iphone got released. Especially, touchphone only had meant "stylus" based touch. So there was no attempt in designing UI for mobile apps that were capable to handle "finger" touch. Apple demonstrated made it real with itouch.

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
