(08 February 2023 – Milpitas, CA) – Comba Telecom, Inc. (Subsidiary of Comba Telecom Network Systems), a global leading wireless solutions provider, today announced their next generation 700/800MHz public safety bi-directional amplifiers (BDA) and battery backup Unit (BBU) platform, named CriticalPoint NG (NextGen).

The new CriticalPoint NG BDAs supports 700/800MHz public safety networks and will be available in either 0.5 Watt or 2 Watt models providing wireless coverage of up to 300,000 square feet.  Similar to our award-winning first generation CriticalPoint BDAs, the NG platform will also come in Class A or Class B and will be software configurable.  What sets the NG platform apart from the previous generation:


  • Greatly improved noise factors
  • Faster ALC (automatic level control) response time that supports P25 phase 2 per timeslot
  • Up to 64 channels per band on single band models; up to 96 channels shared across bands on dual band models (maximum of 64 on individual band) (Class A)
  • Fully FCC compliant (<9dB Noise Figure) low gain mode
  • A more powerful GUI and tools for commissioning, updating and maintaining the ERCES system

Additionally, the NG system includes a new battery backup unit (BBU), sold separately.  The BBU will be offered in either a 30AH, 60AH or 100AH capacity to satisfy a wide range of requirements of local ordinances. The new BBU is powered by the same Lithium iron phosphate batteries (LiFePO4) found in our current Version 2 BBU, however the chassis is 30% smaller and 20% lighter.  Lithium Iron Phosphate batteries are extremely stable and have been a proven technology for decades.  They are lighter in weight, have 3 times the service life of lead acid batteries, and provide better performance than typical lead acid batteries, making installation easier and needing less maintenance trips between battery replacements.  The NG BBUs accomplish the reduction in size, weight, and cost by containing only the batteries; the charger and supporting controller boards are located in the NG BDA.

“We are happy to announce our next generation of BDA and BBU to the ERCES market,” says Steven Cheng, Comba Telecom’s Product Manager. “These new products demonstrate Comba Telecom’s commitment to providing state of the art, excellent performing solutions that support the in building communications of our nation’s First Responders”.

Comba’s CriticalPoint NB BDA and Battery Backup Unit will be shipping on or before February 28th, 2023. For more information visit:
