ICM(idle mode Measurement) band troubleshooting..

check for Co-BCCH, adjucent-bcch, Connectors, jumper and vswr test will help to identify what is the cause of Interferences..

Hi Devendra,,
Normally we are facing ICM band high in Combine DAS (IBS),
Reason:
1. due to connector not done in proper manor.
2.which you used accessories for DAS that accessories not meeting PIM value.
3.Fq interface in from the BTS end
4.if we have DAS connectivity in Inside the BTS room then you need to reduce the BTS room radiation.

Diffrent B/W MIMO & SISO: in single word we can say,MIMO means multi input multi output ,,,SISO single input single output

Regards,
Daya

how to resolve ICM value is high for IBS site? pls help me.

kitururu - 24th June 2016  (08:23 GMT)

High ICM band ( 2 and up) means there is interference on TCH and SD channels on Idle mode. do frequency scanning on the area to identify the cause of inter fences and check for hardware issues (jumper, connectors ) on antenna system installation

ankit.singhal85@yahoo.com - 8th April 2015  (05:35 GMT)

how we define the interference band for the GSM. specify the 3GPP TS for that.

shen - 5th February 2015  (11:08 GMT)

Previously when the site had just GSM 900 ICM band was ok but after carrying out expansion with GSM 1800 in second carrier ICM band raided and traffic reduced. Is there any relevance and how can I solve it?

What are the reasons for HIGH ICM band?
