**4 WATTS (36 dBm) POWER AVAILABLE FOR cnReach N500 RADIOS RUNNING AT 900 MHz FREQUENCY for MAS band**

All new cnReach (900 MHz MAS band) N500 radios shipped after March 2018 will have the capability of having the maximum power transmission available to reach 4 Watts = 36dBm.

For legacy cnReach 900 MHz N500 radios that the GUI only allows configuration of up to 3 Watt transmission power configuration for MAS band, patch “xw.set-900-4W\_patch” should be applied to the OS update to support 4 Watt transmission power. No hardware change is required. This patch works with both 5.2.15 and 5.2.16 software releases.

Please contact Cambium Networks support by opening a ticket for requesting the patch to maximize the cnReach N500 transmit output power to 4 Watts for MAS 900 MHz band radios. Cambium Networks support team can be contacted at the following website:
