BNN is a wireless services providing organization, offering Turnkey Services for the past 20 years for RF and Transmission Planning for GSM,CDMA & Wimax Network, Radio Interference, Band Clearing Services, Network Planning & Optimization (Fixed / Mobile), EMF Measurement and Compliance, Interference, Spectrum scanning etc

BNN has also set up several SAR (Specific Absorption Rate) laboratories in both in India and Abroad and also operates a state of the art SAR laboratory in Delhi/NCR by the name of BNNSPEAG. As part of this activity, BNN has also undertaken Shielding Effectiveness measurements for few customers including Department of Telecom (DoT)/Telecom Engineering Centre (TEC)


Compulsory India Laboratory testing has started a sudden expansion in the EMC/EMI labs as well as associated activities. There is a requirement of an NABL accredited testing of Shielded Chambers so far being undertaken by foreign vendors.

BNNEMR has acquired all necessary test equipment required to undertake this activity and offers measurement/testing of Shielding Effectiveness of shielded enclosures, rooms between 9 KHz to 40 GHz. The onsite testing and measurement of Shielding Enclosures is carried out as per following scope:-

  • IEEE 299: 2006.
  • Enclosures and boxes having all dimensions between 0.75m to 2m as per IEEE 299.1: 2013.
  • Appendix A of MIL Std. 188-125.2: 3 Mar 1999.
