Installation Planning


Questions to consider when planning a radio network

Area of coverage required.

Where is the location of site i.e. UK or abroad, on or off shore etc. this will dictate whether you need a licence and what frequency you can use.

What is the site topography (any hills or woods in the middle of site?)

Where is the antenna to be located

What does the site contain i.e is it a warehouse containing substances that may absorb or reflect radio waves?

Any obstacles such as stacked containers, or port-a-cabins, if so how high are they?

Planned location of base station to which information is sent, and where is it in relation to the outstations.

Is the base station building brick single or multi level, port-a-cabin single or stacked.

Are the outstations to be installed on devices, people or vehicles?

If you plan to use the modems on vehicles or battery powered devices, are they 12v or 24v ?

Are you using a 3 wire system, if so DTR must be held high.

What is the total number of outstations required and have you made provision for a spare?

At the four corners of the site, are there any services? i.e. electricity if so, what volts?

Will you be using ‘license free’ UHF frequencies or do you have a licensed frequency?

If you have a UK licensed frequency from OFCOM what channel separation and power is it.

Do you know of any other users in the area that may cause interference i.e. airports, factory estates, manufacturing sites, military establishments.

Are any of the modems to be installed in the open? If so they will need to be housed.

What method will be used to get information back from the outstations i.e. will they be polled in turn?
Are any of the modems in a particularly awkward location or housing as they may be better off having a display as it would make it easier to maintain.If you are using a repeater to get to a roving outstation that may come within range of the base station, use overhop. See manual under source mode routing.

IMPORTANT! Please remember that it is the customers responsibility to ensure that the chosen radio frequency is clear and available for use, and that any required fees are paid and correct licences obtained.  Xl Systems Ltd. accepts no responsibility or liability for system failure or legal procedings either due to radio interference from a third party, or failure to comply to logal regulation
