art 1 – Hardware

Part one of this manual describes the Allgon AR repeaters, i.e. the hardware.

Part one includes Chapter 1 through Chapter 5.

The OMT32 software is described in part two of the manual, starting with Chapter 6, OMT32 Installation.

ALLGON System AB AR Repeaters & OMT32 Hardware – Safety

. Safety

Any personnel involved in installation, operation or service of the Allgon

repeaters must understand and obey the following:

• Allgon repeaters are designed to receive and amplify signals from one or

more base stations and retransmit the signals to one or more mobile stations. Also, the repeaters are designed to receive signals from one or more mobile stations, amplify and retransmit to the base stations. The repeaters must be used exclusively for these purposes and nothing else.

• Repeaters supplied from the mains must be connected to grounded

outlets and in conformity with any local regulations.

• The power supply unit in repeaters supplied from the mains contains

dangerous voltage level, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters.

Authorized service personnel only are allowed to service repeaters while the mains is switched on.

BERYLLIUM OXIDE

HYDROGEN FLUORIDE

• The repeater cover must be secured in opened position, e.g. by tying it

up, at outdoor repeater work. Otherwise, the cover can be closed by the wind and cause your fingers getting pinched or your head being hit.

• When working on a repeater on high ground, e.g. on a mast or pole, be

careful not to drop parts or the entire repeater. Falling parts can cause serious personal injury.

• Any repeater, including this repeater, will generate radio signals and

thereby give rise to electromagnetic fields that may be hazardous to the health of any person who is extensively exposed to the signals at the immediate proximity of the repeater and the repeater antennas.

• The CHA channel board power transistors, the PA amplifier board

power transistors, and the combiners (CMB) contain beryllium oxide (BeO) that is poisonous if present as dust or smoke which can be inhaled. The power transistors mentioned are mounted with two screws as opposed to other transistors.

Do not file, grind, machine, or treat these parts with acid. Warning signs are applied on boards and units that contain beryllium

oxide. These warning signs are shown in the next section.

• The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,

that gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is poisonous. Do not use heating tools when stripping off coaxial cable insulation.

No particular measures are to be taken in case of fire because the emitted concentration of hydrogen fluoride is very low.

• A lithium battery is permanently mounted on the CU board. Due to

the risk of explosion, this battery must not be removed from the board. In case of battery malfunction, replace the CU board. The old CU board can be sent to Allgon for repair.

. Introduction

Figure 2-1. Allgon AR Repeater

Allgon repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc.

A repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously.

To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered.

Control of the repeaters is performed using a desktop or notebook loaded with the Allgon OMT32, Operation and Maintenance Terminal, which can communicate with the repeaters, either locally or remotely via modem. Remote operation can be performed either via a traditional telephone line or via a mobile phone that can be installed inside the repeater.

To be able to control many Allgon AR repeaters in common, there is an Allgon OMS, Operation and Maintenance System.

The repeaters and the OMT32 is described in this manual. The OMS is described in the Advanced Repeater OMS, User’s Manual.

Repeater Types

The following repeater types are available:

• Channel selective GSM repeater

• Channel selective CDMA repeater

• Band selective repeater with fixed band width

• Band selective repeater with adjustable band width

• Combined repeater

In the OMT32, the channel selective 900, 1800, and 1900 systems are called GSM, DCS and PCS respectively, even though these systems may have different names in other parts of the world.

Channel selective GSM repeater

A channel selective GSM repeater can be equipped with two, four, six or eight channels. This repeater type is used for channel selective systems, such as GSM, DCS/PCN and GSM 1900 (PCS).

Channel selective CDMA repeater

A channel selective CDMA repeater can be equipped with one or two channels. This repeater type is used for digital code division systems in accordance with IS-95 or J-std-008 standard.

Band selective repeater, fixed band width

A band selective repeater with fixed band width has fixed filters for a certain band width. This repeater type is used for analog or digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.

Band selective repeater, adjustable band width

A band selective repeater with adjustable band width has filters that can be set to various band widths. This repeater type is used for analog or digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA.

Combined repeater

Some of the above mentioned types can be combined in the same repeater chassis and be in operation in parallel.

ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction

Using Repeaters

In areas where the radio signal propagation is poor repeaters can be used to fill out those areas which are not covered by the base station.

The following scenarios are examples on this:

- Sports arenas

- Fair halls

- Large shopping centres

- Road and railway tunnels

- Indoors in buildings with metal or concrete walls

Other examples where repeaters can be used to increase the coverage are:

- Shaded areas

- Fringe coverage areas

In areas where the traffic intensity is low, it is not cost efficient to install a base station. An Allgon repeater, which can be installed with a minimum of investments, is a much better solution. You save installation costs as well as operational costs.

Examples of using repeaters

Two examples are described in the following sections. An outdoor example in a shaded valley and an indoor example in a sports arena.

User’s Manual VD202 90/EN Rev. 1A 1999-07 2 - 3

ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction

Shaded Area

A valley is shaded by hills. There is a base station 5 kilometers away, but

the lowest signal strength in the valley is less than –100dBm. A mast used for other purposes is available for a repeater installation. The mast height is 42 meter and it is located on a hill. The scenario is illustrated in Figure 2-2.

. Installation

Before installation, read carefully Chapter 1, Safety.

Siting the Repeater

Allgon repeaters are designed for outdoor usage. However, humidity and

temperature changes may have affect on the reliability. A preferable site for the repeater is thus indoor, in a tempered and ventilated room.

Sunshine

If a repeater is placed outdoor and can be exposed to direct sunshine, it is

essential that the air can circulate around the repeater with no obstacle.

The operating temperature must not exceed +55°C due to sunshine exposure. A shelter must be used in this case.

Shelter

Allgon repeaters are designed with a weather proof outdoor case that can

be mounted without any kind of shelter from rain, snow or hail.

If a repeater is to be opened on the site when raining, snowing, or hailing there must be some kind of permanent or temporary shelter. This is applicable to gentle rainfall, snowfall or hail. Limitations for very bad weather is found in the next section.

Allgon can provide a shelter designed for these repeaters. This shelter is shown in Figure 3-1.

Outdoor Installation and Service Limitations

Sited outdoors, the repeater must not be opened for installation or

service at bad weather, such as:

- Intense rainfall, snowfall or hail

- Storm or high wind

- Extremely low or high temperature

- High humidity of the air

Measuring the Output Power Level

Uplink and downlink output power test ports are found on the directional

couplers (DC) at the MS and BS antenna connectors. These test ports are

marked TEST –30dB (see Figure 4-1) and are intended for measuring using e.g. a spectrum analyzer.

The coupling is –30dB approximately. There is no directivity in these test ports, i.e. both uplink and downlink signal can be measured.

Voltage Supply Testpoints

A number of voltage supply testpoints are available in the repeater.

These testpoints are named U7A - U7F for the 7V supply voltages and U26 for the 26V or 10V supply voltage (26V or 10V depending on the repeater type).

A standard multi-meter can be used on these testpoints.

The testpoints are found on the DIA board in the repeater cabinet. The testpoint positions on the DIA board is detailed in the Board and Unit

Descriptions section in Chapter 5.

If the repeater is equipped with a second PSU, e.g. for combined channel/band selective operation, the same set of testpoints are found on the cover DIA board as well.

Repeater Adjustment

The repeater is now ready to be adjusted in accordance with the site conditions and system performance requirements. Pay especial attention to the antenna isolation described in the Operational Status section in Chapter 10.

ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description

. Functional Description

Allgon repeaters work as bi-directional on-frequency amplifiers.

A repeater receives, amplifies, and retransmits signals downlink and uplink simultaneously, i.e. from the base station via the repeater to the mobile stations and from the mobile stations via the repeater to the base station.

The repeater is connected to a BS antenna, directed towards the base station, and to a MS antenna directed towards the area to be covered. These antennas are connected to the repeater with N type male connectors.

To prevent instability due to poor antenna isolation, a built-in antenna isolation supervision feature reduces the gain level automatically when poor antenna isolation is detected.

The Allgon repeaters are controlled by powerful microprocessors.

Alarm and operational LEDs are visible on the repeater front.

The repeater works with convection cooling without fan.

Operational parameters such as gain, channel number, power levels, etc. are set using a desktop or notebook and the Allgon OMT32, which communicate, locally or remotely via modem, with the repeater control unit (CU). Remote operation is performed using a telephone line or a built-in mobile phone equipped with a data interface.

ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description

Repeater Design

The repeater is housed in a cast aluminium chassis that is waterproof,

class IP65, for outdoor use. The chassis has a design suited for outdoor use as well as indoor use.

The chassis consists of a cabinet and a cover joined with hinges. The cabinet contains the repeater circuitry. The cover can either be a thin cover or a large cover. The latter consists of another cabinet which can be used as an empty cover or be equipped as an independent repeater system.

The cover has two external LEDs for operation and alarm indication.

The cabinet as well as a large cover can be equipped for channel selective operation or band selective operation. A combined repeater is normally equipped for channel selective operation in the cabinet and band selective operation in the cover.

Different amplifier boards are used to get the various operations (see below). The amplifier boards are individually shielded and located under metal cover sheets which can be folded out.

Channel selective GSM amplifier boards

Channel selective GSM repeaters can handle up to eight repeater channels (four if the CU part number is K103/1). For every even number of repeater channels, two CHA amplifier boards are required in the repeater, one CHA board for uplink signaling and one board for downlink signaling. Each repeater channel is allocated to a radio channel or switched off. In a GSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), one repeater channel can handle eight calls (sixteen if half-rate encoding is used).

Channel selective CDMA amplifier boards

Current CDMA repeaters can handle two CDMA repeater channels. For every even number of repeater channels, two CSA amplifier boards and two PA amplifier boards are required in the repeater, one pair of CSA/PA boards for uplink signaling and one pair for downlink signaling. Each repeater channel is allocated to a radio channel or switched off.

Band selective amplifier boards

Band selective repeaters can handle one wide band repeater channel. The band width is either fixed or adjustable (fixed for 900MHz repeaters only). A band selective repeater channel requires two BSA boards and two PA amplifier boards in the repeater. One pair of BSA/PA boards for uplink signaling and one pair for downlink signaling.

There is one ALI board in the cabinet which handles alarm and alarm communication.

• DC Directional Coupler, located in shielded boxes which are formed as

recesses in the cabinet.

Two DC units in the cabinet are used as antenna signal directional coupler.

• LNA Low Noise Amplifier, located in shielded boxes which are formed

as recesses in the cabinet.

Two LNA units in the cabinet are used as downlink and uplink low noise amplifiers, and additional two LNA are used in the cover, if equipped.

• DPX Duplex filter, located on the cover plate over the channel/band

selective boards.

• CMB Combiner unit, located on the cover plate over the channel/band

selective boards in channel selective repeaters with more than two channels, and in combined repeaters.

• PSU Power Supply Unit, located downmost in the cabinet, and in the

cover, if equipped.

If the repeater is equipped with an optional Repeater to Repeater Link feature, the following board is also included in the repeater (not valid to channel selective CDMA repeaters):

• RIA Repeater to Repeater Interface Adapter, located in the frame on

the DIA board.
