![]() ![]() # Financial and economical factors (use of more expensive and better quality equipment or not the cheapest installation method)Īnd to match all of those to the required system coverage, capacity and quality needs with each area and service. ![]() # System configuration (BTS antennas, BTS power, cable losses, handover gain) # Behavior and type of mobile (speed, max power level) ![]() # Type of environment (terrain, building penetration) The object of the link budget design is to calculate maximum cell size under given criteria: So by improving one side of the equation would decrease the other side. In a network environment both coverage and capacity are interlinked by interference. Downlink direction limits the available capacity of the cell, as BTS transmission power (typically 20-40W) has to be divided to all users. UMTS WCDMA macro cell coverage is uplink limited, because mobiles power level is limited to (voice terminal 125mW). Link budget planning is part of the network planning process, which helps to dimension the required coverage, capacity and quality of service requirement in the network. ![]()
