level buildings, efficiency suggests stacking telecom rooms to minimize the distance and labor in making
connections among them.
Telecommunications rooms should be established to support the ANSI/TIA–568B requirements that no end
device is located more than 90 meters from a telecom room to provide adequate coverage for both planned
and future applications. This is important to note when the routing of cabling cannot be done in a direct
Telecommunications pathways and spaces are also addressed in ANSI/TIA-569A.
The size and the placement of the telecom room should be planned in accordance with BICSI guidelines
where possible, should provide sufficient working space for maintenance personnel, and provide enough
room to accommodate all reasonable future expansion requirements. This should include panel space for
cable terminations, switches and relays, remote field panels, remote diagnostic and management computer
stations, and power service with redundancy and/or emergency back-up capability.
It is also important to note the guidelines when coordinating with other building design disciplines such as
Mechanical and Plumbing since there are limitations as to what can and cannot pass through, over or around
Special consideration should be given to providing adequate clearances and space for access to the
equipment, HVAC equipment to support typical heat loads generated by communications equipment, and
local UPS to power equipment in the event of a power failure. Work space should be allocated for
infrastructure operating staff and system administrators, and a small maintenance and spare equipment
storage area also should be included.
Telecom rooms that require tenant access should clearly define the area which may be accessed by each
tenant and such access should be physically isolated from airport and other tenant spaces where possible,
or include the presence of an authorizing agent of the airport where such physical separation is not possible.
Physical control of a tenant area can be accomplished by using a secured rack configuration that limits
accessibility, or by locating tenant equipment in a caged enclosure, or by other appropriately isolation and
Access to all telecom spaces should be controlled by the facility access control system and be considered
as among the access control pans highest security portals. Telecommunications spaces should include
exterior and interior CCTV monitoring to protect from internal security threats caused by employee’s or
unauthorized access to the communications network.
If third party equipment is installed in telecommunications rooms, the airport’s network equipment should
be isolated by floor-to-ceiling cages of steel chain link mesh and so should the equipment of each third
party. Access card readers should be provided for each area, with only airport security and airport IT
personnel having access to third party cages.
Wireless Networks and Devices
The ISSA system designer may apply wireless communications methods to extend the network coverage
to areas that are difficult or cost prohibitive with conventional communications methods. Wireless
technologies selected may be one of the following:
Wireless radio LANs (WLANs).
