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 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 with 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:

• 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 cable connector to the device.

If using 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 model
which are defined by Broadband.
HeNB-GW: HeNB Gateway is deployed between HeNB and MME, provide 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. 
WAN port is an SFP port and is named as ID1 in the Network configuration.
LAN port os 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 IP address of PC as 192.168.200.100/24
2. Connect to 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", HeNB will reboot to take configuration into effect.
5. Connect the HeNB WAN interface back to LAN.

Login WebGUI with HTTPS.

Backhaul parameter

Configure the NME/HeNB-GW IP address:
Path: Management > Cell > S1SigLinkServer.

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）

Configure common radio parameters:
Path: Management > Cell

• Duplex Mode: TDD
• TAC: 10
• PLMNID: 00666

Configure Cell 1 radio parameters:

• CellIdentity: 257
• CandidateARFCNList: 38400

Note: EARFCN in Downlink, the Uplink EARFCN will be configured automatically by HeNB.

• CandidatePCIList: 0..503

Note: Range from 0 to 503, HeNB will select PCI automatically.

• FreqBandIndicator: 39
• DL Bandwidth: 100

Note: 20MHz ↔ 100, 15 MHz ↔ 75, 10MHz ↔ 50, 5MHz ↔ 25.

• UL Bandwidth: equal to DL Bandwidth value.
• ReferenceSignalPower: -14

Note: Reference signal power, -14 means (-14+31) 17dBm, max value for product is 9 which will be (9+31) 40dBm.

Configure Cell 2 radio parameters:

• CellIdentity: 258
• CandidateARFCNList: 37900

Note: EARFCN in Downlink, Uplink EARFCN will be configured automatically by HeNB.

• CandidatePCIList: 0..503

Note: Range from 0 to 503, HeNB will select PCI automatically.

• FreqBandIndicator: 38
• DL Bandwidth: 100

Note: 20MHz ↔ 100, 15 MHz ↔ 75, 10MHz ↔ 50, 5MHz ↔ 25.

• UL Bandwidth: equal to DL Bandwidth value.
• ReferenceSignalPower: -14

Note: Reference signal power, -14 means (-14+31) 17dBm, max value for product is 9 which will be (9+31) 40dBm.

Select the "AdminState" when all the above parameters are well configured.
Note: This is the switch to control the RF function, select enable RF function when all parameters are well configured.
Press "Submit", then HeNB will reboot to take configuration into effect.

Checking the RF status:

Path: Management > Cell > Cell1 > OpState, Management > Cell > Cell1 > OpState;
Note: "True" means the radio cell was established successfully.
