A base station allows your business to have a fixed radio control point, so that your office based workers can communicate with colleagues out in the field.
Base stations can be simply installed on your desk, with an external antenna.
You can then quickly contact one, or all of your workers (features depend on configuration).
Simplex operation means that both the base station, and the handheld / mobile radios are all on the same frequency. When the base station, or one of the handhelds (or mobiles) transmits, everyone else can hear the callers voice. This is the simplest system configuration.
Duplex Operation means that two frequencies are used. The base transmit frequency, is the receive frequency on the handheld / mobile radios.
Conversely, the handheld (or mobile) transmit frequency is the base station receive frequency.
What this means in practical terms is that when the base station transmits, the handhelds hear it (all of them in a basic system configuration). However when one of the handheld / mobile radios transmits, only the base station will hear the transmission, not the other handheld / mobile radios.
Selective calling Options
Selective calling options allow a base station operator to select who they wish to speak to. For example if you had 10 workers, each with their own handheld radio, you can choose to speak to an individual worker. You could also have the option of speaking to everyone at once.
Digital or Analogue Base Stations?
Digital offers many great features compared with analogue, however are a bit more expensive to buy.
The main advantage is Radio Spectrum efficiency. What this means is that you can ‘fit’ two radio channels in the same space (12.5 Khz), as one traditional analogue channel. This is particularly useful in cities where frequency space is at a premium, and hence OFCOM Business Radio licence costs are more, compared to the countryside.
Call security from casual eavesdroppers is also normally better with a digital system, compared with analogue.
Analogue however, is perfectly good, and may deliver the system you want, at less cost.
If a base station is being added to an existing analogue system, then we would recommend you consider one capable of working as both analogue and digital.
This then gives you the option to ‘migrate’ to digital in the future as your analogue units come to the end of their useful life. This is cost effective for existing users.
