1.3 General Information

A nanoCell is a GSM cellular infrastructure device operating to ETSI communications standards,

providing improved link performance in an existing GSM network. It extends the cellular

network into areas with limited coverage and interference problems with no changes required in

the GSM network or Mobile Stations (MSs). As shown in Figure 1, the nanoCell is capable of

communicating with multiple network BTSs and will intelligently route mobile calls to the best

network location capable of handling the call based on BTS loading and offered service

capabilities. nanoCells operate in a typical GSM Network, connecting Mobile Stations to the

Base Station best equipped to handle the call.

Figure 1. nanoCell Operational Concept

High spot traffic loads can be moved to other less-loaded base stations thereby increasing the

utilization of overall system capacity.

The nanoCell uses the GSM air interface (Um) for backhaul to the network, creating a path in the

same manner as a mobile station. Backhaul transmission to the network BTS occurs only when

needed and there is no continuous transmission on the idle channels. Standard GSM protocols are

observed and no changes are required of either the network or the mobile stations.

By constantly monitoring its radio environment, the nanoCell can rapidly adapt to changing

conditions due to new network equipment, failures in the network, transient loading of Base

Stations, and changing service capabilities of the network.

1.4 System Description

1.4.1 System Operation

The nanoCell contains a base station function (the nano Base Station, or nBTS) and a mobile

station function (the nano Mobile Station, or nMS) as shown in Figure 2.

4 System Commissioning

The following steps are to be followed when commissioning the nanoCell.

4.1 Power-up

Power to the nanoCell is controlled from the circuit breaker panel. When you are ready to apply

power to the nanoCell, place the main circuit breaker to the ON position.

Approximately five minutes to complete the boot process.

4.2 System Start-up

On application of primary power, the nanoCell will automatically start up in a controlled manner.

All nBTS subsystem RF hardware is inhibited automatically on startup to prevent unauthorized

transmissions and is held in an idle state until the unit has been tested and is properly authorized

to operate.

The nanoCell will execute a Boot program from internal ROM on application of power or after

any reset event. Reset events can occur from manual command input, a watchdog timer

expiration, or an anti-tamper event occurrence.

The Boot program will initialize the hardware, perform a compatibility check with the hardware,

execute POST (Power On Self Test), and activate the internal Ethernet port with a command line

interface. The Boot program will report the results of the POST on the command line interface

and on internal LEDs. Any failure of the POST will force the nanoCell to remain in the Boot

program until reset.

It should be emphasized that the command line interface and internal LED display is made

available for maintenance and depot operations only and no external input is required for normal

startup and operation of the nanoCell. Typically there is no connection to the command line

interface port after the unit is installed unless maintenance is required. There are no external

Telephonics Wireless Corporation, Proprietary and Confidential

visual indicators on the unit. Only non-field service would require the unit to be opened for

observation of the LEDs.

After POST successfully completes, the nanoCell’s application program will examine the system

configuration database and complete its hardware and software compatibility checks. If there is a

detected incompatibility or the minimum required data is not present, the nanoCell will wait in a

non-operational mode for data input via the command line interface or remote program load using

BOOTP protocol. Lack of data would indicate that the nanoCell has not been. The nanoCell will

not progress any further until properly programmed and reset.

A connection to the LMT permits the download of additional control parameters and/or

application software as necessary, as well as uploading nanoCell status and event data. The

nanoCell can be commanded to enter the Maintenance mode at any time by the LMT.

Application software may be downloaded via the command line interface while the nanoCell is in

this mode. When valid application software is present, the nanoCell will proceed to execute the

application.

4.3 System Provisioning

The nanoCell is provisioned using the Local Maintenance Terminal software. The information

necessary for input will be contained in the site reference document.

There are two areas that will be addressed during the provisioning process; System Parameters
