Link Budget Calculator

1. The document contains information on calculating the link budget for a wireless network including transmitter and receiver characteristics, propagation loss models, and calculations to determine cell range for downlink and uplink. 2. It provides data on maximum transmit power, antenna gain, cable and body losses, noise figures, interference margins, required Eb/N0, and other technical specifications needed to design the network and ensure sufficient signal quality and coverage. 3. Based on a carrier frequency of 1900MHz, calculations are shown to determine the allowed propagation loss and expected downlink and uplink cell ranges for medium and large environments using the Okumura-Hata path loss model.
