1. UmSITE

The UmSITE is an IP-backhaul GSM Base Station, seamlessly integrating functionality that is usually provided by GSM components such as BSC, MSC, VLR, HLR and SMSC. Its software-centric design enables unprecedented flexibility, supporting remote configuration, maintenance and upgrade, and covering everything from transmit power control to end user features.

2. Installation

NOTE: Base station comes with already installed and configured software, just attach GPS antenna, GSM antennas and power supply.

Steps:

  • Place the UmSite on the mast directly, with connectors down.
  • Attach GSM antennas. We recommend having at least 10 feet (3m) between them.
  • Attach GPS antenna. Good antenna visibility to the sky is required.
  • Turn on Base station.
  • NOTE: GSM antennas are not included in a standard package. We do not recommend to operating the base station without antennas.

    2.1 Antennas installation

    Each of the antennas complement each other. The second antenna must have the same position as the first antenna on a mast, as well as the same direction and incline angle to the ground.

    For the GPS antenna, there are no strict requirements, only good antenna visibility to the sky


    For the mast at least of 100 feet (30m) in height, antennas can be mounted upright within the 10 foot (3m) distance between each other.

    NOTE: Every cell is configured with a BCCH carrier. Generally, the TRX ID of BCCH is fixed to be the smallest TRX ID in the cell.

    Therefore, TRX1 antenna has to be situated below the TRX2 antenna. For example, if the connection would be established when the TRX1 antenna is higher and then it has been assigned to a timeslot of the lower antenna TRX2, call connection could be lost.

    The antenna attached to the TRX1 should not have an advantage by height in that particular case.

    2.2 Getting started

    1. • Connect to the power source and turn it on. LED on the front panel will begin flashing in one to two minutes after being turned on.

    2. • Make sure that the Ethernet cable is connected.

    NOTE: We strongly recommend not putting UmSITE on a public network. Connect it to your local network where there is access to the Internet through NAT or Firewall. Keep UDP port 1195 open on your server for Fairwaves VPN in case of technical support

    Take any GSM phone with any SIM card and try to search the network. The network might have a different name, such as Fairwaves, 1011, Test, etc.

    2.3 Test call

    Searching for the Network

    1. Launch the Settings from the menu system.

    2. 1. Select More

    3. 2. Select Mobile networks

    4. 3. Select Network operators

    5. 4. Select Search networks

    Options:

    • • 1002 - echo call (listen yourself)

    • • *#100# - to figure out the number that was assigned to your phone.

    2.4 Log in

    In order to configure UmSITE, you have to login into device remotely over SSH. The Interface configured to obtain IP address via DHCP and also has a static 192.168.50.100

    Connect laptop to the UmSITE via Ethernet cable.

    NOTE: Make sure your interface in the same subnet as the UmSITE and has IP like 192.168.50.101

    1. 1. Run PuTTY
    2. 2. Type IP address: 192.168.50.100
    3. Login: fairwaves
    4. Password: fairwaves

    You may use a defferent client software for remote access, but we recommend PuTTY (you can download it at www.putty.org ). PuTTY is an open source SSH and telnet client, for the Windows platform.

    Login over Serial cable (Only for UmSITE)

    Serial connection allows you to choose boot options and log into the system if network connection is not available.

    You'll get options like:

    1. 1. Advanced options for Ubuntu
    2. 2. Test RAM memory

    First of all, you have to use USB Serial Adapter for the connection (which is not included in a standard UmSITE package).

    For the Windows user putty

    You can find a number of the COM port at the Desktop manager.

    For the Linux user minicom

    shell> minicom -D/dev/ttyUSB0 -b38400 -o
    

    2.5 IP and network configuration

    eth0 - 192.168.10.10 This is internal interface linked to the UmTRX. Do not edit this

    eth1 - Configured to obtain IP address through DHCP. In case of recovery, it also has a static IP 192.168.50.100

    Edit eth1 in /etc/network/interfaces.d/ In order to change network configuration

    Shell> sudo nano /etc/network/interfaces.d/eth1
    

    Refer to Ubuntu documentation for details

    NOTE: The base station is configured to get an IP address through DHCP. We also recommend to keeping the configuration for the eth1:1 (192.168.50.50/24) because it's used to as a backup IP address. If you want to configure a static IP address, change eth1 configuration.

    2.6 Base station sensors

    In order to obtain insights of temperature, voltage and TRX power of the base station you can run:

    Shell> umtrx_query_sensors  

    The output is:

    Shell> Sensors:

    NOTE: If 'Return Loss' value:

    < 6dB = major alarm state (100% malfunction)

    < 10db = minor alarm state (Check antenna for water subject)

    > 10dB = partly good (probably bad antenna or water in cable/connector)

    > 12dB = good

    > 15dB = excellent
