External AC/DC power converter (optional)
The figures below displays a typical setup (using BSDU) of the MicroMAX(s) mounted outdoors on a
pole (with an integrated antenna).
Power
The SDA-4S is a switch providing the MicroMAX BSR with -48 VDC power supply, and
10/100BaseT interface with the subscriber's PCs/network.
The BSDU is also responsible for providing BSRs with -48 VDC power supply and for
synchronizing BSDUs, BSRs and Base Stations (when a GPS is implemented).
An external AC/DC power converter (optional) is available in the event -48 VDC is not
available at BS site. Contact your Airspan supplier
Models
The MicroMAX is available in the following basic physical designs:
MicroMAX with a built-in (integral), internal antenna
MicroMAX with an N-type type RF connector for connecting an optional third-party external
antenna
Note: A MicroMAX with an N-type port for attaching a third-party external antenna does
not provide a built-in antenna.
