Hi;
I am interested in tips on litterature on mathematical models on e.g. this:
I have estimates for TIS & TRP respectively for some different environments for two different phone models. I know network performance for one of the phones, and want to calculate network performance for the second phone model. How does a lower TIS & TRP (sensitivity and transmitted power) in a cell phone affect the performance in a network environoment, e.g. more dropped calls, decreased setup call success etc.Any tips on relevant books etc are highly appreciated.
it depends :
do you have a good overlap with neighbor cells or not ? if you’re in a city, with high gsm coverage, having a phone with low TIS/TRP will probably not impact the KPI.
if you’re in a rural area, designed in such a way that at the cell border you’re having “critical” radio conditions (just before making HO to neighbor), then the impact of TIS and TRP is high.
You’ll measure : more call drop rate, less ho success rate, more emergency ho rate (on low dl signal strentgh, or low ul sign str.), less tch traffic in the cell, and also :
more sdcch assign failure rate
lower average RXLEV in the cell
less power control adaptation (the average BTS power attenuation and MS power attenuation will be a bit less than before)that’s about it…
