This application can be used for frequency and channel number conversions between different mobile phone network technologies (GSM, WCDMA, FD-LTE, TD-LTE). You may well find this tool useful if working, for example, in mobile network (frequency) planning, BTS maintenance, R&D or I&V testing areas. The app can also be used to perform conversions between typical radio technology units, such as RF power (dBm, W), Return Loss and VSWR as well as to provide a cumulative total for logarithm dBm power values.

Bands and calculations included:

* GSM bands: 850/900/1800/1900
* WCDMA bands: 1,2,4,5,8,9,10,11,19 (incl. Additional channels on bands 2, 4, 5, 10, 19)
* FD-LTE bands: 1,2,3,4,5,6,7,8,9,10,11,12,13,17,18,19,20,21,25,26,28
* TD-LTE bands: 38,39,40,41,42,43
* WCDMA-GSM: Calculates GSM ARFCN's on both sides (in +/-2.0 and +/-2.4 MHz points) of a given WCDMA UARFCN. This calculation is typically needed when the existing GSM band is shared with WCDMA. Calculation can be done in 850, 900 and 1900 bands.
* LTE-GSM: Calculates GSM ARFCN's on both sides of given LTE EARFCN considering also the given LTE bandwidth (1.4/3/5/10/15/20 MHz). This calculation is typically needed when the existing GSM band is shared with LTE. Calculation can be done in all four GSM bands (850, 900, 1800 and 1900).
* WCDMA-LTE: Calculates LTE EARFCN's on both sides of given WCDMA UARFCN. This calculation is typically needed when the existing WCDMA band is shared with LTE. Calculation can be done in 900/1900/2100/2100_1700 bands and with selectable LTE bandwidth option 1.4/3/5/10/15/20 MHz.
* dBm W, Return Loss VSWR: Mathematical conversions between typical RF measurement units.
* Sum dBm: Calculates the sum of given dBm power values and shows the result in dBm and Watt.
