Summary and Ideas

Main goal is testing the 3g network based on free open source software from osmocom-project and a nano3G femotcell from ip.access with different test devices (TD)
  • TD1: Acer Liquid M330, Dual-SIM Windows Phone E3336 with Windows10 Mobile
  • TD2: LG G3 LG-D855 android Phone with Android 7.1.1 (LineageOS 14.1 nightly build)
  • TD3: Samsung Galaxy Tab2 10.1 GT-P5100 with Android 4.4.4 (CyanogenMod 11 nightly build)
  • TD4: Huawei HSPA+ USB stick E1823 (used mainly with debian8)

Another aim is to extend the documentation to help users with little or no experiences with UMTS-networks.

Journal

2017-03-08 The nano3G femotcell arrived.

2017-03-13 Software is running. First successful registration of TD2 and TD3

2017-03-19 Successfully tested voice-calls and sending SMS between TD1, TD2, TD3

2017-03-26 TD1, TD2 and TD3 have internet-connection via HSDPA.
Results of browser-based internet speedtests of devices connected to the nano3G with an internet connection of 250 Mbit/s down and 20 MBit/s upstream:
  • TD1: 5852 kbit/s downstream and 488 kbit/s upstream
  • TD2: 6430 kbit/s down- and 481 kbit/s upstream.

2017-03-31 First tests with TD4 and wvdial/pppd: Connection worked, but Modem hangup after CHAP-authentification

2017-04-01 Using the latest sources from git with TD4 the pppd now gets an IP-address.

2017-04-08 After changing the wvdial.conf to force the TD4 to register on the UMTS-network, with "AT+CREG"-command, the IP-connection via pppd is working now.
Results of browser-based internet speedtests of devices connected to the nano3G with an internet connection of 250 Mbit/s down and 20 MBit/s upstream:
  • TD4: 6871 kbit/s downstream and 438 kbit/s upstream

FAQ

Problems, issues, topics which came up during the setup of the nano3G, configuration of the software and running the 3G-network.

SIM / USIM

Q: Is it possible to use a USIM-card from a commercial provider?
A: No, you need to know the Ki-key which cannot be read from the USIM-card.

Q: Is it possible to use a SIM-card?
A: No, only USIM-cards work with the 3G-network.

HLR

Q: How to create the HLR?
A: Use the hlr.sql included in osmo-hlr software and create the HLR with: cat hlr.sql | sqlite3 hlr.sqlite3
