BAN Working Frequency: a Trade-Off Between Antenna Efficiency and Propagation Losses
Abstract
This communication addresses power issues at physical layer in Body Area Networks. Friis equation is discussed by taking into account body path loss and antenna efficiency from frequency ranging from 400 MHz to 60 GHz. Then power balance is presented for fixed antenna dimensions and varying frequency in order to establish a balance.
