ERICSSON WCDMA LINK BUDGETCALCULATION

Version 1.0

The scope of this document is to outline how to calculate the UL and DL coverage ofthe Ericsson WCDMA radio access network. The methods descried can e used forrough estimates suitale in the dimensioning process.

Using this document the user will e ale to! calculate free space path loss using "kumura#$ata propagation formula calculate UL and DL %adio network design ma&imum path loss calculate sensitivit' of the %() and UE for various services calculate link udget margins get overview of link udget losses perform link udget calculations for the UL and DL* oth for the $)D+A and
