RadioFrame System Method of Procedure GSM/802.11b
Pre-Installation
20 RadioFrame Networks, Inc.
3.2.1.2 Remote ACUs
Remote ACUs are located in Telco rooms or other closets throughout the building. Any
such location must be free of dust, wind, salt and liquids. All other operating environment
specifications that apply to an ACU in the main rack also apply to a remote ACU.
Remote ACUs must be mounted in a 19” EIA-standard compliant rack or equivalent. The
racks for remote ACUs must be either floor or wall mounted. Any other mounting method
is not approved, and could void the warranty on the product and other components in the
RFS.
The number of RFUs required to provide coverage for the GSM/802.11b/g RFS
determines the number and location of remote ACUs.
3.2.1.3 RFUs
The RadioFrame System is designed to simplify site planning. The capacity requirements
of the site determine the number of GSM RadioBlades and 802.11b/g iRAPs that will be
required. RFUs are mounted so that the antennas of the installed GSM RadioBlades and
802.11b/g iRAPs point to the ground. This orientation of the antennas must not be
changed.
The number and exact location of RFUs is determined by capacity and coverage
requirements, as well as site considerations, such as mounting considerations, interior
structures, and interference from macro systems.
3.2.1.4 LAN
Connecting the RFS to the customer LAN requires only a single Ethernet cable from the
BCU in the main rack to the customer’s LAN equipment (gateway, switch, router etc.). No
other site considerations are required.
3.3 Main Rack and Supporting Hardware
Most communications equipment is mounted into standard 19” EIA racks or enclosed
cabinets. Follow the rack and/or equipment manufacturer's instructions when installing
equipment into racks or cabinets.
For example:
• All supplied bracing hardware shall be properly utilized.
• Proper hardware shall be used to secure equipment.
• Convected heat transfer from one piece of equipment rack to another shall be
considered. Heat baffles may be required.
3.3.1 Mounting
The front panels of the BCU and ACUs are 19” wide to allow for installation into 19” wide
cabinets. For rack installation instructions for the BCU and ACU, see Appendix C BCU
and ACU Main Rack Installation.
