Hi dear osmocom folks,
I have been doing some bitrate throughput tests from different MS (i.e. phones
models) connected to a working osmo-nitb/sgsn/ggsn configuration (with a nanoBTS
DCS1800) and i get 15kbits/s maximum (tcp/udp transfer) with the gprs subnet
nat-ed to a 100baseT
lan connected to a 2Mbits/s dsl line
The channel configuration is as follow in the osmo-nitb configuration file :
<file /etc/osmocom/bsc.conf>
(...)
nominal power 23
max_power_red 0
rsl e1 tei 0
timeslot 0
phys_chan_config CCCH+SDCCH4
! hopping enabled 0
timeslot 1
phys_chan_config TCH/F
! hopping enabled 0
timeslot 2
phys_chan_config TCH/F
! hopping enabled 0
timeslot 3
phys_chan_config TCH/F
! hopping enabled 0
timeslot 4
phys_chan_config TCH/F
! hopping enabled 0
timeslot 5
phys_chan_config TCH/F
! hopping enabled 0
timeslot 6
phys_chan_config TCH/F
! hopping enabled 0
timeslot 7
phys_chan_config PDCH
</file>
Should i change the channel configuration to get more bitrate ?
Should add more cells (bts?) to add more channels ?
my best, cheers.
Xavier.
