NODE B Dimensioning

Hi all,

Can you share me a discussion or reference about Node B Dimensioning. Equipment is Huawei DBS3900

Thanks in advance!

For 3900, a few things to consider
1. Cards:What kind of card WBBP B or D card(256 vs 384 CE) capacity
2. CE capacity: how many for UL and DL
3. HSDSCH codes: how many HSPA carriers(each carrier 15 codes)

i want to discuss this topic cause i have some questions since my hardware background is weak .

what is the difference between RRU & WRFU ?
are the used together in the same site ?

RRU is an outdoor/seperate equipment equipment from the BBU unit. They are connected by optical cable and dc cable. Unlike the WRFU its a plug in unit and usually collocated with the BBU in one cabinet (BTS3900). You may refer to my attached file for you reference.
