Reception conditions

Optimising range is a fundamental challenge of radio technology. The reception of information in

marginal zones is patchy at best. Practical measurements are carried out on the premises to deter-

mine the range.

When instructing users, the following instructions can help to achieve optimum results:

• You can usually improve the connection quality through minor changes in location, e.g. by turn-

ing your head or your body.

• Avoid making phone calls in unsuitable places, for example in lifts. Users should be made aware of

these zones during instruction.
