Evertac 400 MHz Radio Repeater Among the First Type-Approved Under China's New Rules

Evertac optical repeater units

Evertac's 400 MHz repeater for private two-way radio networks (model DRFT-BDA UHF) has received radio transmission equipment type approval from China's national radio regulator.

New rules for repeaters

In early 2025, China's State Radio Regulation Office issued new rules for the use of the 150 MHz and 400 MHz bands by two-way radios. Among other changes, repeaters used in these bands now need type approval before they can be produced, sold or used. The new approval rules have applied since 1 March 2025.

Among the first to comply

The DRFT-BDA UHF is one of the first two 400 MHz private-radio repeaters in China to be approved under the new rules — and both of them are Evertac products. The approval can be checked on the website of the Ministry of Industry and Information Technology.

Why repeaters matter

In private radio networks, repeaters fill coverage gaps and extend the signal of a base station:

  • inside supertall buildings, basements and shielded equipment rooms;
  • across airports, rail systems, tunnels and chemical parks, out to every work area;
  • across large campuses and multiple buildings, using fiber links for continuous coverage.

Because repeaters directly affect coverage quality and frequency order in critical sites, the new rules set clearer requirements for frequency use, emissions and spurious control. Evertac started upgrading the product as soon as the rules were published.
