Catatan ini berasal dari Asoka Wardhana dari ITMN.co.id.
- svn ulang ke source codenya, karena kalo pakai svn up langsung dia minta merge config2 , jadi ragu saya pilih download ulang aja.
- Sebelum compile openbts nya, compile dulu a53 yang ada di folder OpenBTS/a53
make make install
setelah itu baru compile openbts yang ada di folder OpenBTS/openbts/trunk
- Config GPRS :
- masuk ke OpenBTSCLI
- Jalankan :
config GPRS.Enable 1
- Yang bagian ini masih perlu di uji kebenarannya apakah menaikan kualitas link GPRS dan bandiwdthnya atau tidak, tapi setelah kita
jalankan config ini terasa lebih baik bandwidthnya :
devconfig GPRS.ChannelCodingControl.RSSI -22 devconfig GSM.Radio.RSSITarget -32
Nilai -22 didapat dari nilai GSM.Radio.RSSITarget +10 , misal nilai GSM.Radio.RSSITarget nya adalah -40 maka GPRS.ChannelCodingControl.RSSI nya harus -30
- Supaya throughput agak bagus, ada baiknya menaikan slot Download, misalnya,
devconfig GPRS.Multislot.Max.Downlink 4 devconfig GPRS.Multislot.Max.Uplink 1
4. Konfigurasi iptables atau enable NAT di linux
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward
eth0 = interface yang terkoneksi ke internet
5. Pastikan /etc/resolv.conf ke IP DNS luar, misalnya
nameserver 8.8.8.8
- Pastikan setelah menjalankan OpenBTS dan GPRS.Enable 1, ketikan ifconfig dan harus ada interface baru yaitu sgsntun
sgsntun Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

- Pada handset GSM Phonenya pastikan data roaming enable/on
