FREMONT, Calif. – SureCall, the performance leading cell phone signal booster manufacturer, today introduced GuardianA, a 2 watt public safety band booster for large buildings. The GuardianA amplifies in-building coverage for critical communication channels, delivering a consistent signal for first responders and safety officials.

SureCall’s most powerful public safety band booster, GuardianA, is a class A bi-directional amplifier supporting both the 700 and 800 MHz public safety frequency bands. Large newly constructed buildings or expansions to existing structures are generally required to have a -95dBm minimum signal strength in designated areas in order to receive a certificate of occupancy.

GuardianA is the most affordable class A booster on the market and meets the code requirements for NFPA 72/1221 and IFC 510, including a NEMA-4 rated amplifier housing.

“When we create products to help support emergency responders, we understand that public safety can depend on us getting every single detail right,” said Frankie Smith, vice president of sales for SureCall. “The GuardianA is the class A booster building managers can trust to help provide secure communication for first responders in the case of an emergency.”

Additional safety features and benefits of the GuardianA include:

  • 32 independently controlled channels per band, including automatic gain control for each channel
  • Supports P25 P1/P2 digital and conventional analog communications simultaneously
  • Channelized Auto Gain Control (AGC) / Channelized uplink squelch
  • Built-in mandatory isolation test to prevent BDA oscillation
  • Ethernet port with built-in SureCall Sentry™ remote monitoring hardware
  • UPS port for external battery backup
  • Energy-saving operation allows bands to remain dormant when not in use
  • Industry leading 3-year warranty, with a five-year extended warranty available

SureCall offers free training and design services for building managers who need to boost public band signals.
