To keep the syntax as short and simple as possible, the programs were written with the aid of Winbatch, a batch job tool organizing and simplifying the transfer of commands and data between the controller and the instrument.

We assume that the mobile phone is capable of operating in the GSM900 band; in the example involving a GSM900/1800 handover, an appropriate dual-band mobile must be used.

This means that the mobile operates on the GSM900 band while the signalling procedures are carried out. ! As soon as the call is established RXQuality and other measurements can be performed in the GSM900 band.
