4.You are planning a WAN to cncompass LANs at two nearby office buildings. One vendor proposes the use of terrestrial radio band of 100 MHz, and an SNR of 10 dB. Another vendor proposes running a cable, with a bandwidth of 40 MILZ and an SNR o 30 dB. Which vender's approach will yield a higher effective bit rate? Blow MHz Be 40 MHz SNR dB - 10 dB SNR dp- 30dB . 5 first vendors Na B & ENRIB B * = 100M* 1 (333.3 Mbps 3 second vendors Na B * SORSR B 7 You mbps 3 The second vendors apprash has a higher effective bitrate = 4.M * 30 5- You ham the
