Rocket M Titanium
AirSync Capabilities
Many situations require the use of multiple AirMax M series
devices on the same tower. For example, the addition of an AirMax
basestation on an existing tower to service a new area or increase
the capacity of an existing network by using multiple basestations
with narrow coverage areas instead of one basestation with a wide
coverage area.
If the devices are using the same RF-band (e.g. 5 GHz or 2.4 GHz),
even if they are configured on separate frequencies, the devices
would interfere with each other. Additionally some RF bands like
900 MHz and 3.65 GHz have only 1 20 MHz channel requiring all
the basestations to use the same frequency. This interference
will cause Receive (Rx) errors on the basestation when it receives
packets from associated stations that are typically miles away.
With AirSync, the basestations make use of a common clock
source using the built-in GPS receiver. One device is configured as
the synchronization master and the others are configured in Slave
Mode and provided with the MAC Address of the Master.
Once this is done, the Master and Slave devices synchronize their
transmit and receive cycles so that they transmit at the same time
and receive at the same time. This resolves the interference issues.
