Overview
• Goal of the Presentation:• This presentation attempts to layout the standard RRU and BBU configurations for the markets. Each
configuration is a “per sector” view.
•The choice of RRU & BBU configurations depends on:• The required number of 1900 MHz Carriers (CDMA + EVDO)• Software release 2.0 timeline
• Diplexers are to be avoided• Exceptions when Two 1900 MHz RRUs required and only 1 antenna possible (example Flag Pole)
• If Towers can not support RRUs, then Ground Based alternative can be considered
•.

BBU2 Needs:• 1 UAMA card (LTE control)• 1 L9CA card (for 2 5MHz carrier LTE)
BBU Configuration: For CDMA/EVDO Carriers = 1 to 6 (up to Five 1900 MHz + One 800 MHz)
BBU1 Needs:• 1 CIMA cards (CDMA control)• 3 CICA-A or CICA-D cards (CDMA & EVDO traffic)• Note, one of the CICA cards will have 800 MHz CDMA

BBU3 Needs:• 1 CIMA cards (CDMA control)• 3 CICA-A or CICA-D cards (CDMA & EVDO traffic)Note – 800 MHz CDMA is set on one of the CICA cards
BBU Configuration: For CDMA/EVDO Carriers = 8 to 12(up to Eleven 1900 MHz + One 800 MHz)
Note: For Sites with only 7 & 8 1900 MHz carriers (after SR 2.0) the 2nd 1900 MHz RRU can be avoided if all carriers are powered down 1dB(**RF Approval required)

CICA-D cards• Can only do 1 EVDO carrier• And, can do 1 Voice carrier (either 800 or 1900 mHz)
CICA –A cards• Can do 2 Voice Carriers (either carrier can be 1900 MHz or you can change
one to 800 MHz)
1 BBU can support 3 traffic cards (or 6 carriers)• But, 4 EVDO’s will trigger 2nd BBU• 1 RRU can handle 1 CDMA BBU + 1 LTE BBU
• a second CDMA BBU would require a 2nd RRU
Attached is the formulas to calculate The correct number of CICA-A & CICA-D cards
