tower or airave (weird)

[balagyi]

Hi All,
my phone has been connecting to the tower from tower right our street corner. The reason I say tower is that I can see that building has lots of cell towers on the roof.
and recently my phone is showing it's connected to apartment next door.
I assume it's not tower and it must be Airave.
is there a way to tell I am connecting to Airave or Tower? and how can i tell phone to connect to Tower? this is because eversince I connected to next door, my 3g speed become really bad.

my phone spec:
ReRFS Format Stock ROM EC05 with bonsai master key
modem: EC05
software i use to check: Open Signal Maps

as always... thanks in advance
