RSSI estimation in multi-technology communication terminals

A receiver, comprising:

• reception circuitry, which is configured to receive signals in a given frequency band in a first set of first communication channels each having a first channel bandwidth, and in a second set of second communication channels each having a second channel bandwidth that is larger than the first channel bandwidth;
• and
• processing circuitry, which is configured to measure first Received Signal Strength Indications (RSSIs) for the respective first communication channels, to compute second RSSIs for the respective second communication channels by applying an arithmetic computation to one or more of the first RSSIs, and to select from among the first and second sets, using the measured first RSSIs and the computed second RSSIs, at least one of the communication channels over which to receive the signals by the reception circuitry.
