Access to the rooftop or tower and equipment room must be available day or night, 24 hours each
day for emergency repair or configuration.
Arranging access with the appropriate partner (facility security personnel, or the building/tower
owner or lease-holder) is the responsibility of the wireless equipment owner.
Access to telecommunications services
Where access to telecommunications services or to back-bone network attachments are required
by network design, permission to route fiber or cable to the equipment room must be arranged by
the wireless equipment owner.
Rooftop/tower requirements
The following rooftop/tower requirements apply.
Rooftop/tower modification
Depending on international, national, territorial, regional or municipal regulations, rooftop/tower
equipment may be affected by one or more of the following:
• allowable maximum height of mounting poles allowed on the rooftop or tower,
• color of exposed outdoor equipment and cable,
• aircraft glide slope (as governed by ICAO/IATA standards),
• equipment wind loading and structural impact of equipment added to a rooftop or tower.
These issues must be considered, and resolved with appropriate national, territorial, regional or
municipal authorities, as well as with the owner and lease-holder of the property.
Safety
Equipment must be installed in such a way that installers and maintenance personnel are not at
risk. Elevated installations must have accessible places for the proper connection of safety straps,
to prevent accidental injury due to falls.
Equipment must be installed in such a way that public safety is not at risk due to falling equipment
or tools during installation and long term operation.
Third-party equipment
Rooftops may contain third-party equipment that interferes with the RF or line-of-sight require-
ments of the system. If such conditions exist, this information must be provided to network design
staff for contingency planning or alternate site selection.
Rooftop or tower access
Rooftop or tower access should be limited to authorized personnel only. All entry points to the roof-
top or tower must be clearly marked with RF hazard signs.
Equipment room requirements
The following equipment room requirements apply.
Proximity to the X-Pol RBS Tx and X-Pol RBS Rx radios
The equipment room should be located in an area that is central to each sector pair of X-Pol RBS
Txs and X-Pol RBS Rxs, to provide convenient cable access. The equipment room should be lo-
cated as close to the rooftop level as possible, to reduce cable length requirements.
Shelf space
Each equipment rack requires 0.652 m
2
(7.02 ft2), in accordance with Bellcore GR-63-CORE.
This space requirement includes wiring and maintenance space.
