About Zenitel Radioteknik 

Founded in 1981, Zenitel Radioteknik specializes in designing equipment 

and solutions for radio coverage in confined areas and areas suffering from 

propagation black spots. 

Co-operation with authorities and other customers from the mission-critical sectors 

has over the years resulted in an enhanced product portfolio, building upon a 

unique RF design competence and know-how and offering solutions giving 

outstanding radio performance, regardless of the surrounding environment – since 

year 2000 this has resulted in new orders for digital solutions, based on the TETRA 

standard and deploying Radioteknik’s line of sophisticated TETRA repeaters and 

amplifiers. Locations can be as diverse as tunnel and metro systems, oil drilling 

platforms, marine vessels, large public or private building complexes like e.g. 

shopping and entertainment centres, plants, hospitals, car parks etc. 

With a world unfortunately experiencing an increasing need for mission-critical 

communication systems, there is an equally increasing need for having this 

communication available at all locations, especially those underground or indoor 

where coordination of public safety services becomes crucial for optimising rescues 

and limiting damage and casualties.For this reason many confined areas, previously 

covered by analogue radio systems, will in the near future require TETRA 

infrastructure coverage. Zenitel’s Radioteknik brand stands ready for further challenges, 

this time providing and securing digital communications.

Solutions for Confined Areas 

Confined Areas such as underground spaces, tunnels and large buildings don’t generally 

have satisfactory radio coverage from outdoor transmitters. High performance 

retransmission systems must be deployed to make these locations accessible to radio 

communications and, in particular, to allow emergency services to coordinate safe 

intervention. The extension of radio coverage to Confined Areas has become a sensitive 

subject since the events of September 11th and the subsequent London attacks. 

A Confined Area is an enclosed location where radio coverage can’t be guaranteed from 

an outdoor base station. Confined Areas experience significant loss of penetration of radio 

frequencies, either because of the use of materials that cause strong attenuation - metal, 

reinforced concrete and metallic glass - or a structure that constitutes an obstacle to the 

propagation of exterior waves, such as underground tunnels and buildings with narrow openings. 

Various services necessitate radio coverage in confined areas, such as consumer services 

comprised mainly of cellular telephony and FM radio; analogue or digital professional radio 

communications systems used by public transport companies, security companies or technical 

services; and emergency services radio systems used by the police, fire brigades and 

ambulance services.

THE SOLUTIONS 

There is no single solution for radio coverage in confined areas. A specific study must be carried out for 

each confined area to determine the most appropriate solution to be selected, taking account of the requirements 

of retransmission systems, functionality and capacity; the configuration and use of the locations 

including dimensions, type of environment, materials used and obstacles; and particular constraints such 

as a esthetics, protection against vandalism, fire control and redundancy. Radio coverage in confined areas 

requires specific retransmission solutions, in particular integrating repeaters, antennas and radiating cable. 

Coverage solutions can be broken down into two major elements: Radio Equipment and Radiating Infrastructure. The 

radio equipment is the RF source in the solution to extend coverage. The equipment retransmits and amplifies the 

outdoor radio signal inside the confined area. The radiating infrastructure distributes the retransmitted signals in the 

confined area and ensures the required radio coverage. 

Radio Equipment 

The radio equipment comprises the active elements used to generate or regenerate radio signals in a confined area. 

There are various possible RF sources. The two main ones are the repeater, which is connected by cable or off air to 

a surface base station and comprises a bidirectional amplifier, and the dedicated base station, which is connected to 

the exterior network and provides a cell for exclusive coverage of the confined area. A mobile radio gateway mode 

used as a temporary or backup solution for a TETRA network allows communications from terminals operating indirect 

mode inside the confined area to be relayed to the outside. 

5

Mobile Radio Gateway 

A TETRA system has two separate operating modes for mobile terminals: trunking mode (TMO), where all communications 

pass over the network infrastructure via the base station closest to the terminal, and direct mode (DMO), 

where the terminals communicate with one another locally outside the network coverage, similar to walkie-talkies. In 

a confined area without radio coverage, the terminals could potentially communicate with one another in direct mode, 

but would lose any connection with the rest of the network. However, a TMO/DMO gateway allows communications 

from a group of users operating in direct mode to be relayed to the net-work and vice versa. This type of mobile radio 

can be used to maintain a connection between the surface radio network and a group of users moving into a confined 

area and therefore, in away, to extend the radio coverage to inside the confined area. 

Nevertheless, gateway mode on a TETRA mobile radio wasn’t designed to provide a structural solution to the problem 

of radio coverage in a confined area. Although gateway mode is inexpensive, it is a temporary or an emergency 

solution to cover a sudden incident or a particular situation and suffers from the following limitations: 

•Only relays a single group of voice communications - no individual or data communication 

•Requires manual switchover of the portable terminals operating in the confined area from TMO to DMO 

•Requires an RF channel dedicated to direct mode and an appropriate frequency plan 

•Isn’t economical in terms of spectrum use because DMO only allows a single communication by RF channel, 

whereas 

trunking mode allows four. 

Repeater 

The repeater acts as a bidirectional amplifier, capturing, filtering, amplifying and retransmitting the RF signals 

between a base station and a mobile terminal in two directions (uplink and downlink) simultaneously. The repeater 

increases the cell size of the base station it is connected to by extending the radio coverage to places that aren’t 

directly accessible. 

A repeater doesn’t add any capacity to the radio system; the traffic in the confined area covered by the repeater is 

added to the initial cell. The repeater is a flexible, affordable solution, suitable for radio coverage of the vast majority 

of confined areas. 

6

The main features of a repeater are the RF power, gain, linearity and selectivity. There are two main categories of 

repeaters: Channel-selective repeaters, which use highly selective filters, and individual amplifiers to retransmit a 

defined number of narrowband RF channels independently. They are used to extract the desired channels from congested 

spectrum by avoiding any problems of inter modulation with other users in the same radio network or other 

systems. 

Band-selective repeaters use broad band filters and amplifiers to retransmit all RF channels used in a specified 

band width at once. The bandwidth of TETRA band selective repeaters is typically 5 MHz. These repeaters are intended 

for situations where the spectrum is controlled; the channels in the repeater’s band width are identified and 

limited in number. 

Depending on the dimensions and complexity of a confined area, it maybe necessary to use several repeaters to 

ensure satisfactory coverage everywhere. The following two principles should be used, either in isolation or combination: 

Cascade the repeaters 

The main repeater — generally channel selective and linked to the base station - serves as the RF source in the 

confined area and is connected to the radiating infrastructure. The other repeaters are then inserted into the radiating 

infrastructure periodically and gradually extend the coverage. These successive repeaters are linked to one another 

and to the main repeater by cable across the radiating infrastructure. The in-line repeater is a band-selective 

repeater because the channels it amplifies are controlled and known. 

Optical distribution of RF signals 

The system of distributing radio signals via optical fibre allows an RF source to be inserted in different places in 

one or more confined areas, which may be along distance apart. The main repeater is connected to a module that 

converts the RF signal into an optical signal and vice versa and distributes it to each retransmission substation over 

optical fibres. Each substation has an optical fibre-fed repeater including transducers and a band-selective repeater. 

The optical substations have their own radiating infrastructure connected to the band-selective repeater. 

Distribution via optical fibre has some advantages over cascading in-line repeaters. Optical distribution offers 

multiple injection points for the RF signal inside the confined area, allowing at least partial coverage in the event of 

the failure of a repeater or damage to a cable section in the radiating infrastructure, while coverage from cascaded 

repeaters originates from a single injection point. Optical distribution permits redundancy in coverage by feeding 

a radiating infrastructure with a different optical substation at each end. But the optical solution is more expensive 

unless the fibre is already in place and suffers from a reduced dynamic. 

7

Indoor Base Station 

An indoor base station adds capacity — channels for traffic — to the coverage in the confined area. The unit is 

connected to the indoor radiating infrastructure, and its cell is limited to the confined area. An indoor base station is 

an expensive solution that can be justified only for large-scale confined areas with a large number of potential users. 

It requires an appropriate frequency plan with at least one separate RF channel that is different from those used by 

the surrounding surface cells. An indoor base station also requires a permanent connection to the network switch. 

Radiating Infrastructure Infrastructure 

The radiating infrastructure distributes an RF signal inside the confined area and guarantees the required radio coverage. 

The infrastructure may be partially shared by different radio systems using different frequency bands. It isn’t 

unusual to re-use certain parts of an existing radiating infrastructure when extending the coverage of a new radio 

system in a confined area. 

The radiating infrastructure consists of various elements. The actual radiating elements provide the radio coverage 

for the mobile terminals. The radiating elements propagate the RF signals to the terminals (downlink) and capture 

the RF signals transmitted by the terminals (uplink). This includes mainly radiating cable and antenna. 

Passive components are used for optimum distribution of the RF signal and for combining with other signals while 

sharing part of the infrastructure. The main passive components used are the splitters/combiners for two or more 

ways, directional couplers, duplexers and cross-band couplers. 

Coaxial cables, which provide the connection among radio equipment, radiating elements and passive components, 

spread out in the confined area. The architecture of the radiating infrastructure must be specifically adapted to the 

configuration of the confined area to obtain the required coverage. 

Tools 

Several tools can evaluate and compare the efficiency of various RF architectures and verify the solution used. 

These tools provide an estimate of the level of the radio signal that would be received by a portable or a mobile 

terminal inside a confined area. There are three main categories of tools. Prediction methods are generally used to 

ensure that the level received by a radio terminal is greater than the coverage threshold in the most critical places: 

the points farthest from the radio equipment and radiating sources, areas of overlap and coverage boundaries. 

Simulation techniques allow the signal level received anywhere in a confined area to be evaluated. The results are 

often shown as a coverage map that gives the contours of the signal received at a certain height above the ground. 

The simulation software uses ray-tracing or ray-launching methods based on geometrical optics and integrates 

deterministic modelling of propagation mechanisms. Preliminary measurements characterize the penetration of the 

outdoor radio signal in the confined area, check the possibility to re-use an existing radiating infrastructure, and 

verify a solution by measuring the coverage of temporary antennas. These tools are based on a detailed and balanced 

link budget, which determines the exact RF level of the transmitted signal that feeds the radiating infrastructures. 

Engineers specializing in radio communications use these methods and equipment; it’s a niche market served 

by only a few companies worldwide.
