Communications circuitry 26 may include radio-frequency transceiver circuitry for handling various radio-frequency communications bands. For example, circuitry 26 may include transceiver circuitry that transmits and receives data in 2.4 GHz and 5 GHz bands for WiFi? (IEEE 802.11) communications and the 2.4 GHz Bluetooth? communications band. Circuitry 26 may include cellular telephone transceiver circuitry for handling wireless communications in frequency ranges such as a low communications band from 700 to 960 MHz, a midband from 1710 to 2170 MHz, and a high band from 2300 to 2700 MHz or other communications bands between 700 MHz and 2700 MHz or other suitable frequencies (as examples). Circuitry 26 may handle voice data and non-voice data. Wireless communications circuitry in circuitry 26 can include circuitry for other short-range and long-range wireless links if desired. For example, circuitry 26 may include millimeter wave communications circuitry (e.g., circuitry for supporting 60 GHz communications and communications in other millimeter wave bands), circuitry for receiving television and radio signals, paging system transceivers, near field communications (NFC) circuitry, etc. Circuitry 26 may also include global positioning system (GPS) receiver equipment for receiving GPS signals at 1575 MHz or for handling other satellite positioning data. In WiFi? and Bluetooth? links and other short-range wireless links, wireless signals are typically used to convey data over tens or hundreds of feet. In cellular telephone links and other long-range links, wireless signals are typically used to convey data over thousands of feet or miles.
