[Openbts-discuss] handover between USRP1 and N200

[Dmitri S. <dm...@ma...>]

Hi!

I'm testing handover between USRP1 and N200.
when handover takes place between timeslots of the same site, HandoverAccess is observed at the desired logical channel.
when handover is targeted at another ARFCN, access busrt (with handover access) appears at a random timeslot

Below there are 3 sequential measurement outputs, http://thre.at/kalibrate :

dmisol@tosh:~/kal-v0.4.1$ src/kal -s 1800
kal: Scanning for DCS-1800 base stations.
DCS-1800:
    chan: 708 (1844.4MHz - 31.694kHz)    power: 3413.88
    chan: 714 (1845.6MHz - 27.053kHz)    power: 455.22
    chan: 878 (1878.4MHz + 32.263kHz)    power: 746.14

dmisol@tosh:~/kal-v0.4.1$ src/kal -s 1800

DCS-1800:
    chan: 710 (1844.8MHz + 4.514kHz)    power: 3342.11
    chan: 714 (1845.6MHz - 4.087kHz)    power: 451.43
dmisol@tosh:~/kal-v0.4.1$ 

N200 (ARFCN 826) is transmitting 20 sm south-west at the same table, not detected at all..

Q1. can it be the source of problems?
Q2. what is the easiest way to solve it?
Q3. any other ideas?

Thanks,
Dmitri
