Hardware Installation Guide Safety Guidelines
2.4. Cabling
Warning: The maximum cable length between the radio transmitters (i.e., BSR
and SPR) and terminating equipment is 100 meters.
Warning: Cables with exposed ends (i.e., not yet crimped) should be covered
with protective polythene bags during external cable installation processes.
Note: Prior to the commencement of any installation, commissioning work at
‘live’ sites it is the responsibility of the Airspan engineer to advise the
customers representative before any activity commences. If in doubt assume
equipment is ‘live’.
Warning: Disturbance of cables on an In-Service exchange can cause loss o
f
service. Extreme care must be taken when installing cables at any customer o
r
subscriber premises.
2.4.1. Considerations
The following issues should be considered during cabling at the WipLL Base Station
and customer premises:
 Cable routes are to be defined in the site-specific documentation.
Note: A minimum separation of 200 mm should exist between power and data
cables. However, it is permissible to allow these cables to cross each other at
right angles.


Observe recommended minimum bend radii when installing copper cables.
Wherever a cable changes direction, ensure that it does so in a smooth curve
with a radius of at least 50 mm to prevent damage.
Plastic ties and wraps are to be used to secure cables at regular intervals to trays,
guides, and mounting pole/bracket. Ensure all trimmed ends are disposed of
safely and at regular intervals.
