Intercell 10 B38+B39

The intercell 10 B38+B39 is an outdoor TDD-LTE dual carriers base station with 2*(2*10W) output power (each carrier supports 2x2 MIMO with 10W output for each RF channel).

Quickstart

Please follow these quick steps to set up your device:

  • Connect external antennas and Ethernet cable to the connectors (see "Expansion ports and slots");
  • Connect the device to the power source (see "Powering");
  • Connect your laptop to the Ethernet port for configuration.
  • The device can get the IP address by DHCP and Static assignment;
  • Once connected, default maintenance IP address: 192.168.200.200, user name: admin, password: MikroTik;
  • If connecting with the Static assignment method, configure the IP address of your laptop as 192.168.200.100/24, then connect through HTTPS to the device: 192.168.200.200;
  • Configure backhaul and radio network see "Configuration".

Powering

The device accepts power in the following way:

  • The input power jack accepts 48 V DC⎓. The only connector with cable is provided with the package, you will need the power unit - generating 48 V.

The power consumption under maximum load can reach 200 W.

  • Connect provided cable to your power source.
  • Connect the cable connector to the device.

If using an Ethernet cable add RBGESP to the setup, which comes with the package.

Configuration

All configuration is necessary to carry out through the webGUI.
The configuration of this device should be done by a qualified person.

This topology shows typical Smallcell network architecture. HeNB works as LTE
the base station provides LTE service to UE；

NMS: HeNB management system (HeMS) is a virtualized solution that provides a full lifecycle
of small cell management functions. It supports TR-181 and TR-196 data models which are defined by Broadband.
HeNB-GW: HeNB Gateway is deployed between HeNB and MME, providing the
aggregation of control and user plane traffic and capabilities necessary to manage
large clusters of small cells. It plays functions of data aggregation and forwarding,
and S1/X2 proxy

Configuration Flow

HeNB can get the IP address by DHCP and Static assignment. 
The WAN port is an SFP port and is named ID1 in the Network configuration.
LAN port is an Ethernet port and is named ID2 in the Network configuration.
In the DHCP method, can check the HeNB IP address by MAC Scan.
In the static assignment method, configuration procedures are as below:

  1. Configure the IP address of the PC as 192.168.200.100/24
  2. Connect to the HeNB WAN interface directly, login WebGUI through HTTPS
    Default maintenance IP address: 192.168.200.200
    User name: admin
    Password: MikroTik
  3. Configure HeNB IP address
    Configure "Address Type" as "Static"
    Configure "IPv4 address" and "Mask" accordingly.
  4. Press "Submit", and HeNB will reboot to take the configuration into effect.
  5. Connect the HeNB WAN interface back to LAN.

Radio network parameter

Output power calculation table

Please see the formula and table on how to determine output power：

Output power of each antenna = ReferenceSignalPower  + Base（dBm）

Output power of 2 antennas = ReferenceSignalPower + Base + 3（dBm）
