Can I define random maio for cell in eric system.
eg 666 site
Cell A 0,11,2,13,4
Cell B 5,1,7,3,9
Cell C 10,6,12,8,14
I know that there are too many hits in this maio plan… but I have only 15 freq,,, hence this is the max. I can d.
Please reply soon..

you have 15 MA frequencies to put on a site which contains 15 SFH TRX’s ? This is mad !! There is going to be a terrible call drop rate, due to adjacent channel interference (probably uplink, mostly)
you should remove 7 TRX’s if you want good QoS 🙂18th July 2008 at 19:49 #53150AlexGuest
I think it is possible to have 10 TRXs per cell.
3 TRXs just carry BCCH in the separated Channel Group number 0 without hopping and 7 TRXs can be shared between 3 sectors with SFH e.g. configuration can be 3+4+3.
Please note to this formula:
“number of frequencies in the HFS” >= 2*(number of TRXs in the CHGR)

alex, yes, i was talking about SFH TRX, hence not taking into account the “bcch” trx.
the actual rule, in SFH 1×1, is to have nb of “tch” TRX < 12% * nb of MA frequencies. otherwise the soft blocking is going to be over the top ! in "MAIO"'s situation, i strongly recommend a BBH solution, not SFH.29th August 2008 at 15:29 #53152ali abbasGuest
how the priority of MAIO is decided.Where is SFH and Baseband are used.8th September 2008 at 20:46 #53153VictorGuest
I think it´s possible to have 15-Freq MAL for 15 SFH-TRXs, but your must create a MAL with non-consecutive ARFCNs to avoid collisions.. (if you have enough #channels, obviously).
