SPECIFICATIONS
AX1255 Network Hub
Transceiver
Wireless Channels
Downstream: 20, 6.0 MHz Channels
Upstream: 14, 3.2 MHz Channels
7, 6.4 MHz Channels
Wireless Frequency Range (TX) 5.725 to 5.850 GHz; (RX) 5.250 to 5.350 GHz
Maximum Transmit Output Power High: +19 dBm (Note: The “High” power setting is for
use with the AX1255-SM-90 and AX1255-VM-90
Network Hubs. Use of the “High” power setting with the
AX1255-SM-25 cancels the FCC certification and voids
the user’s authority to operate the unit in the 5.8 GHz
band.)
