Link budget calculations 

Link budget is an estimation of the path loss between the transmitter and receiver. In 

cellular network, link budget is calculated for both uplink and downlink paths. There are 

several parameters fed to the link budget which in return calculates maximum allowable 

path loss that exists in the link path. The calculated path loss can be used with the se-

lected propagation model such as Okumura-Hata model to find the cell coverage. It can 

then be used to compare coverage between different access technologies and frequen-

cies theoretically. The link budgets in Appendix A and Appendix B conclude with the 

downlink maximum path losses for LTE and UMTS respectively.
