amitHi Amit,
I do not have answers for you but have a question instead! What is this RBS-2111 ? I heard it is based on remote radios (RRU). Can you tell me what this is and how different it is from RBS-2108.
Thanks,
RK
dear amit,
check ur rx optical cable,check vswr,n swap ur feeder cabletrong luong, cac chi tiet cua tu RBS 2111, 3206,
i have need a descrption of RBS 2111 if possible send me a doc
there is problem in rru jumpers.check it by swaping or change it.
I NEED SOME DIFFERENCE BETWEEN 2111 AND 2108
RBS 2308 have jumper and feeder cables beetween base station and antennas.
RBS 2311 have optical cables beetween MU (main unit) and RRU (radio remote unit). So MU can be on the ground, and RRU can be on the top of the pole together with antennas. So the line is MU—optical cabel—RRU—jumper cable—antennas.
RBS 2311 is practical when you can not apply feeder cablesregards
2111 is a macro cabinet having RRU which can be connected in remote location using OFC cable connected to the Main Unit.
My questions to u are:
u have mentioned 3 sectors with 3 cabinets. there has to be 3 RRU’s and one MU interconnected with OFC cable. Is this done?
The maximum configuration possible with one MU is 2+2+2. wats ur present config. One RRU=2 TRX. Hence 3 RRU with 3 sectors is 2+2+2 max. Else there is also possibility to connect 2 RRU n combine which will give u 4 TRX combined.
Dear Friends, Where i can to download intermdiate/advanced documentation to RBS 2111, tankyou in advance.
I NEED TO DO THE CONFIGURATION 4+2+4 USING TWO MU AND 5 RRU, MY QUESTION IT S OBLIGATORY TO USE THE SYNCROSITION CABLE BETWEEN TWO MU?
NOTA I USE TWO MU IN CASCADE MODEANY INFO PLEASE
U can always cascade. U can have ESB cable for the same. N there is ESB dummy too for the same.
Please PRABEEN,
I have not too well understood your answer, thank you for me better expland
do I rest my question it is obligatory to use the ESB cable to make this configuration?
if you have a document that can help me prayer to send it to mei want to know about E1 cable punching colour coding scheme in rbs 2111.
i want no mor about ericson RBS . Were am i going to laern it?
