Ultra BTS can support max. of 12 TRx (trancievers), while
Flexi can support max. of 24 TRx.
Ultrea has drawback that it has all Pin connections on back
side, if any of the Pin of a particular slot is damaged
then that slot is useless, while in flexi all connections
are on front side so it is easy to install every equipment.
As an operator wants to cover maximum area he will use
flexi.
you can say ultra a bts of old times.
so, it is the difference.
however, one TRx card supports 8 time slots i.e. max of 8
users, but not practically. It will support max. of 7
callers. Capacity in terms of users can be increased using
Half rate, i.e. A TRx will support approximately 14-15
users at half rate transmission, half rate is used during
bysy hours, i.e. on one time slot 2 user will send their
data/speech, with a half rate of 5.6 kbps, but at half rate
voice quality is not very good. Simply one time slot will
be assigned to two users in Half rate. So both of them
(Ultra & Flexi) support equal no. of users if having equal
no. of TRx.

Answer / asad

Flexi have very low power consumption, i.e approximately 60%
less than ultra BTS. Secondly Flexi is weather friendly is
can sustain upto 55^C temperature range.
Flexi cover less area than Ultra, Due to small size no extra
civil work is normally required to expansion.
Flexi one physical TRX support two TRXs logically that is
why it is easy to expand.
