Wireless communication uses a broadcast medium. Links are only logically defined by your MAC layer or routing protocol. Additionally you do not have something like a universal "bandwidth of the wireless channel". This depends on your technology, modulation schemes etc. So you have to setup this value depending on your model technology (e.g. 2 Mbit/s for a WLAN using BPSK modulation).
