Warnings and Cautions

This system is designed to be operated indoors as a fixed system device and must be located either on or near the ceiling away from the user. It must be mounted in a manner to ensure that all users and bystanders and users are kept a minimum of 60mm away from antennas at all times.

Do not touch or move the antenna(s) while the unit is transmitting or receiving.

Do not hold any component containing a radio such that the antenna is very close to or

touching any exposed parts of the body, especially the face or eyes while transmitting.

In most parts of the world, regulatory approval(s) are needed before the nanoBTS is operated.

Do not connect any device other than the nanoBTS to any RJ45 socket that has been enabled for nanoBTS connection (i.e. 48Vdc operation).

The nanoBTS is intended for dry indoor applications only. If evidence of condensation is present do not apply power to the nanoBTS.

The nanoBTS must only be powered using a PSU supplied by ip.access.

PSUs supplied by ip.access must not be used for powering any other equipment.

Introduction

The nanoBTS

The nanoBTS is a picocellular basestation operating in one of the GSM frequency bands and complies with all the relevant ETSI / FCC specifications. A nanoBTS basestation is mounted on a wall or ceiling, taking its power and traffic from a single 10/100 switched Ethernet connection.

The range of the nanoBTS exceeds half a kilometre in an uncluttered environment and inside buildings can be expected to support users within a radius of up to 50m or more, depending on the building construction materials.

The nanoBTS is physically linked to the BSC over an IP network and uses standard GSM protocols to connect to the existing Public Land Mobile Network

The diagram below shows the system architecture. Calls within the installation are passed over the IP network and are handed over to the PLMN if the mobile leaves the installation coverage area and is out of range of the ip.access basestations.

Figure 2 nanoBTS

The nanoBTS may be mounted on walls or ceilings, in convenient locations chosen at the system planning stage, to provide adequate coverage in a building. Power to the nanoBTS is via the RJ45 socket enabled for 48Vdc. The nanoBTS has a LED indicator used to convey its status. This indicator can be disabled after commissioning if required using the nanoBTS installer software. For wall mounted installations and installations on sloping surfaces it is preferred that the cable access is from the bottom as this prevents the ingress of dust and condensation, but where circumstances dictate the nanoBTS may be mounted to allow cables access from the top of the unit. When mounted on a ceiling the plastic clip-on cover ventilation and cooling.

Configuring the nanoBTS

Step 1. Setting up PC for configuring nanoBTS

Three options exist for commissioning the nanoBTS.

Option 1: Option 2: Option 3:

This section covers the steps required to configure the nanoBTS using option 1. The other options are covered in the appendixes

Check that the following files are loaded onto the laptop PC

C:\ipaccess\Software Releases\ C:\ipaccess\Tools\Windhcpd\windhcpd.exe C:\ipaccess\Tools\Windhcpd\com.ipaccess.nanoBTS.v1

Configuring mostly at the site IP switch room Configuring mostly at the BTS. See appendix 3 Configuring mostly at the NOC (Network Operations Centre) See

appendix 4

”software file name.sdp”

Using a text editor, open the file C:\ipaccess\windchpd\com.ipaccess.nanoBTS

.v1

that has been prepared as part of the system planning process. The file is in the following format.

# FILENAME: com.ipaccess.nanobts.v1 # Configuration file for windhcpd to server to ip.access nanoBTSs # NOTE: values in this file override those in dhcpd.conf for nanoBTSs # ################################################################ ########### Basic IP configuration in standard DHCP ########### ################################################################ subnet = 255.255.0.0 router = 172.28.0.254

# The lease time is mandatory for a successful lease # The value is in seconds. NOTE nanoBTSs assume lease-time=-1 makes the served # IP and VSI configuration static, and disables future DHCP !!! lease-time -1

# filename and next-server options tell the nanoBTS to do a TFTP download # from the next-server (or from this server if omitted) using the given filename filename = bts-software.sdp next-server = 172.28.0.1

################################################################ ############## VENDOR SPECIFIC INFORMATION (VSI) ############## ################################################################ # # VSI options for all MAC addresses can be specified here #omlipaddr = 172.28.0.30 # default omlipport is 3002 for IPA SW BTS builds, may as well has this default. omlipport = 3002

################################################################ ############## MAC SPECIFIC (VSI) ############## ################################################################ # MAC-specific options can be included too - these override the above defaults # e.g. # 00:02:95:ff:ff:01 ipaddr=172.28.3.1 lease-time=-1 omlipaddr=172.28.2.42 #

- 15 -

# you can specify any of the following options per MAC address line: # ipaddr= # subnet= # router= # lease-time=3600 # filename= # next-server= # omlipaddr = 172.28.0.30 # omlipport = 3002 # 2ndomlipaddr = 172.28.0.30 # 2ndomlipport = 3006 # location = "On my desk" # btsid = 42 # trxid = 0 # # NOTE that MAC addresses are case sensitive and should be in lower case.

00:02:95:00:00:0a ipaddr=172.28.6.10 btsid=1 location=”room 1” 00:02:95:00:00:03 ipaddr=172.28.6.3 btsid=2a location="room 2 west wall" 00:02:95:00:00:04 ipaddr=172.28.6.4 btsid=2b location="room 2 east wall" 00:02:95:00:00:05 ipaddr=172.28.6.5 btsid=3 location=”reception”

Update the file to reflect the settings specified in the site configuration plan. The

DHCP server uses this file, to pass all of the configuration information, including the IP address to the nanoBTS, and then stores the IP address as a fixed address.

Note:

If no software is to be downloaded to the nanoBTS, the [filename] field should

be left blank.

Step 2. Connecting the nanoBTS

Connect all the RJ45s to the switch.

Start the DHCP server and the TFTP server by running

C:\ipaccess\tools\windhcpd\windhcpd.exe (or use the desktop icon). The following screens are displayed when the servers are running and no further intervention is required, as the servers will automatically respond to requests from the nanoBTS.

Figure 8 DHCPD server

- 16 -

Figure 9 TFTP server

Step 3. Setting IP addresses and downloading software

The DHCP server automatically responds to the nanoBTS broadcast with the relevant

IP configuration.

If a .sdp filename has been specified in the “com.ipaccess.nanoBTS

configuration file, then the software will download from the TFTP server to the nanoBTS. Check against the IP address in the TFTP server window that the .sdp file has been downloaded and that no error / fail message is displayed.

Figure 10 TFTP server window when active

Setting the frequency of nanoBTS oscillator

The frequency of the nanoBTS is referenced to a crystal oscillator that has to be accurately calibrated to 26MHz ± 20ppb. The frequency can be adjusted using either of two methods: a) Calibration by synchronisation to other GSM base stations transmitting locally. This is the preferred method, as described below. b) Using a frequency counter and manually adjusting the frequency. This is an alternative method that can be used at the BTS site as described in Appendix 2

.v1”

)

- 17 -

Note:

The following steps 4, 5, 6 and 7 should be done on one nanoBTS and then repeated on

each remaining nanoBTS in turn.

Step 4. Calibration of nanoBTS using frequency synchronisation

Note:

Prior to calibration, the unit must be powered up for a minimum of 60

minutes, to ensure frequency stability.

Start the nanoInstaller and open a session to the nanoBTS by entering the IP address of the nanoBTS for which the calibration is to be performed.

Repeat tests 4, 5, 6 and 7 for each nanoBTS.

Step 8. Measuring path loss between nanoBTS

This test is designed to measure path loss between pairs of BTS sites so that the TX power can be adjusted to achieve required coverage (typically 95%).

In this step each nanoBTS is selected in turn to transmit and the signal is measured on all other nanoBTS in the building. The information from each test will be entered into a matrix on the installation report, as shown below.

Step 9. Walk Test

This test is performed to fine adjust the nanoBTS(s) as agreed to give a suitable service meeting the coverage levels specified in the site configuration plan.

Set each nanoBTS into beacon test mode on its allocated ARFCN and power level as

calculated in the previous step. (See Step 8)

Using a test mobile or other GSM measuring device, walk through the installation site

looking for areas where service is below the threshold specified in the site configuration plan, recording black spots.

Individual BTS power levels may be adjusted to minimise areas of poor network performance.

Record all locations that are subject to poor reception.

Step 10. Installation Report

Compile an installation report for the network operator to enable them to set their BTS neighbours, cell list, power levels and handover thresholds to optimise the network.

The report should contain: -

•

BCCH information

•

Channel usage

•

Path loss matrix

•

Walk test results

• Completed site configuration plan

This completes the installation and configuration of the nanoBTS site.

Appendix 3: Commissioning at the nanoBTS

If commissioning is to be done mostly at the nanoBTS instead of connecting the PC to LAN in switch room (step 2) the laptop PC should be set up at the nanoBTS as shown the diagram below using the power over Ethernet adapter to connect the PC onto the LAN (the adapter applies the 48V DC to the nanoBTS). Connect a crossed RJ45 lead from the adapter to the Ethernet connector on the nanoBTS.

Communication Problems

No LEDs

Does the BTS have Power?

LED is on but is flashing orange (1sec on, 1sec off)

The unit is powered up but does it have proper connection to the installation PC.

Check that the BTS is connected to the Ethernet cable and ensure it is plugged in fully into the Ethernet socket. Check that the Ethernet cable is plugged into a power supply. Check that the Ethernet is plugged into the correct socket on the power supply (BTS). LED’s have been disabled using nanoInstaller Check that the power supply is connected to the mains and powered up.

Check the Ethernet cable between power supply unit and installation PC. Check that the cable between PC and Power supply unit is crossed, if connecting directly to the nanoBTS Check that the Ethernet is connected to a correct (Live) socket on the hub. Check that the DHCP server is running on installation PC

No communication between the nanoInstaller and the BTS

Check that the Ethernet cable is connected between

Check that nanoInstaller is not set to look at the wrong IP address or port number

the installation PC and the BTS via the power supply box.

Clock Adjustment Problems

No 26MHz clock during Frequency adjustment

Clock adjustment cable not plugged into TIB-OUT

socket on BTS.

Unsettled 26MHz during frequency adjustment

Has the BTS been powered up long enough to warm up? Warm up time is normally less than 60 minutes but can sometimes take over one hour if the unit has been stored in a cold environment before power up.

Problems During Beacon Test

No signal seen on other nanoBTS during beacon test

The nanoBTS is not enabled to transmit a beacon The power level of the beacon BTs is set too low. Select a higher power level. A white list has been applied which does not include the beacon channel If using the external antenna, ensure that the cable connections are in place.
