The document, issued by the Telecommunication Engineering Centre (TEC) of India under the MTCTE certification scheme, establishes the mandatory technical requirements for the approval and use of point-to-point digital radio relay systems operating in the E band (71–76 GHz and 81–86 GHz).

It is designed to ensure that this equipment meets parameters of electromagnetic compatibility, electrical safety, transmission quality, and efficient spectrum use, in accordance with national (TEC, DoT/WPC) and international (ETSI, IEEE, IEC) standards.

The document covers two product variants:

• E-band Full Outdoor Microwave System, which integrates transmission and reception functions in a single device.

• E-band Outdoor + Indoor System, which combines an outdoor unit (ODU) with an indoor unit (IDU) and supports a wider variety of interfaces.

WHOM DOES IT IMPACT?

The direct impact is on mobile and fixed network operators, manufacturers, importers, and suppliers of E-band equipment, and regulators.

CONCLUSION:

It establishes mandatory requirements for the certification of E-band fixed radio link systems in India, ensuring electromagnetic compatibility, security, spectral efficiency, and reliability in critical networks. Compliance is essential for manufacturers and operators seeking to deploy high-capacity links essential for 5G expansion and next-generation connectivity.
