Introduction
ACRS 1.0 is the first generation Adaptrum cognitive radio system covering spectrum bands from
400 MHz to 1 GHz. Although capable to operate in other spectrum bands below 1 GHz, Adaptrum ACRS
1.0 is specifically designed to operate in the UHF TV Band (470 MHz – 698 MHz), as TV Band Devices
compliant to the rules specified in CFR 47 Part 15 Subpart H. To be rules-compliant, ACRS 1.0 systems
must operate as Fixed TV Band Devices and must be professionally installed. ACRS 1.0 system
specifications are shown in the following table.
