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.
