6.3.5 Antenna Separation

Caution There can be no co-location of MC-SCDMA with Mobile WiMAX basestations. If 2 or more BSs are

co-located on the same structure, they must run the same technology or be upgraded in the same

maintenance window. Use frequency separation to minimize interference between a MC-SCDMA and

Mobile WiMAX basestation. A reasonable frequency separation is 15 MHz for BSs that are 2 kilometers

apart. The exact frequency separation may differ on a case-by-case basis. Therefore, 15 MHz with 2

kilometers between basestations may not provide enough separation. Refer to the BWX Mobile WiMAX

Migration Planning Guide for more information on distance requirements.

Caution All BSs in a network must have the same DL/UL symbol ratio. The default recommended ratio is 32/15.

Cisco does not support basestations that use different DL/UL symbol ratios in the same area because they

will interfere with each other. Please refer to the BWX EMS Configuration Guide for more information

on parameter settings.
