4 UHF frequencies
4.1 Radio regulations
The uPASS Access reader operates on the 860 – 960 MHz band. Regulations in this band are not standardized world-
wide. Generally the regulations can be divided into several regions.
Per region a specific frequency band is available. This frequency band is divided into frequency channels. If local radio
regulations require frequency hopping (FHSS), then the uPASS Access automatically selects and uses the available
channels.
4.2 Frequency channel selection
If no frequency hopping is required, you should select an available frequency channel manually. This can be realized as
described below. Select an available frequency channel to achieve the best performance and to avoid interference from
other readers or equipment.
Use UHFTOOL to setup the frequency channel selection. See for more details chapter 5.3.4.
