What that means the (interference band 1 to 5 ) in NSN
hi experts
in orther to localte the cells with interference, i got a report (Average number of full rate TCH in interference band) with those paramaters :
AVE IDLE F TCH 1 (c2006) |
AVE IDLE F TCH 2 (c2008) |
AVE IDLE F TCH 3 (c2010) |
AVE IDLE F TCH 4 (c2012) |

Hi,
I haven't yet worked with NSN 2G equipment but this is pretty universal:
BTS measures interference in every IDLE timeslot (BTS knows when it's idle so there should not be any useful transmissions in this timeslot at that particular moment so everything that it's receiving is noise).
Measured noise is mapped to counters: for every timeslot there are 5 counters. Each counter is a threshold that you probably can configure:
For example:
Counter 1: all samples that are below -110dBm
Counter 2: samples between -105 -110dBm
Counter 3: -100 -105
Counter 4: -95 -100
Counter 5: all samples above -95dBm

These interference band threshold are atleast tunable in huawei, not sure about other vendors.

Interference band is tunable for E******* and NSN - Thanks for the correction komitko

That is definetly not true for NSN, pitoyco. They are tunable (on BTS level, if I remember correctly).
