The Rohde & Schwarz Wireless Communications Calculator is an essential part of any wireless engineer’s toolkit. Featuring all of today’s most important and popular cellular and non-cellular standards, we cover them all from A to Z. Just enter the radio access technology and band of interest, and we do the rest. Enter a channel number and we’ll provide the correct downlink and uplink frequencies in both numeric and graphic format. Low, mid, and high channels are also shown for a quick reference. Enter a downlink or an uplink frequency and we’ll provide the correct downlink and uplink channels. In the “power” mode, we give you the maximum UE power allowed for that class device, or, in the case of GSM, power versus PCL/Gamma.
