Abstract
Method for planning and/or dimensioning links between several stations in a wireless telecommunication system including the following steps: a) establishing a relation, in logarithmic scale, for each existing link between the ground equivalent radiated power, EIRPground, the signal to noise density ratio required (C/No)req for a link, and a quality indicator QaF, b) determining the quality indicator QaF from the contribution of the first type items (link analysis disturbance) that are linear in EIRPground and the second type items that are non-linear in EIRPground, c) determining the EIRPground from the quality indicator QaF determined in step b).
Claims19
A method for planning and/or dimensioning links between a plurality of stations or items in a wireless telecommunication system comprising the following steps:
- a) using an existing link, in logarithmic scale, to establish a relation between the ground equivalent radiated power, EIRPground, the signal to noise density ratio required (C/No)req for a link, and a quality indicator QaF,
- EIRP
- ground
- =
- (
- C
- No
- )
- req
- -
- QaF
- where C/No corresponds to the total signal to noise density ratio;
- b) determining the quality indicator QaF from the contribution of the first type disturbing items that are linear in EIRPground and the second type items that are non-linear in EIRPground, using:

- c) determining the EIRPground by taking into account the quality indicator obtained and the C/N0 required.
