Architecture
MA 850A1 consists of the following main
functional modules:
•
Interface:
Provides interface to the 802.11b/g AP ports.
•
Gain control mechanism:
Gain control to adjust 802.11b/g signals to specific site
•
Combining and separating mechanism:
On the downlink, combines the amplified
802.11b/g signals with the 802.11a AP signals and those of mobile services. On the
uplink, separates the signals and routes them to the corresponding ports.
•
Monitoring and control:
Support for WEB monitoring, SNMP MIBs displayed via a
standard Web browser and local RS232 and service options.

1.3 Installation
Configurations
The MA 850A1 can be installed as a standalone unit or integrated with MA 1000/2000 systems
and its signals converged with the mobile services to be distributed through the MA 850A1
antenna connections.
MA 850A1 can be installed in the following configurations:
•
Standalone – to provide coverage only for 802.11a/b/g services
•
Add-on to a MobileAccess 1000 series RHU (with and without MA 1200 add-on)
•
Add-on to MobileAccess 2000 system
NOTE:
In all installation types, all the signals are converged via the MA 850A1 and distributed
via the antennas connected to the MA 850A1 antenna ports.
