A wireless communications device employs a method of access technology selection that comprises analysing radio signals for indications of the device's current physical environment. In response to this analysis, it is determined which of two or more candidate environments are the most likely current physical environment of the wireless communications device. The wireless communications device then selects, from among all possible access technologies, a subset of access technologies typical of the determined environment. The wireless communications device then performs a wireless access discovery over frequencies corresponding to said subset, and selects a suitable access technology thus found by the discovery process.
