The Rohde & Schwarz Wireless Communications Calculator for iOS 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 Zigbee. Just enter the 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. 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.
