WIRELESS CONTROL SUBSYSTEM FOR A MOBILE ELECTRONIC DEVICE

Methods and apparatus are provided for wireless communications in a mobile electronic device. In one aspect, the mobile electronic device includes an antenna subsystem and a plurality of wireless communications modules. A method may involve supplying RF signals from each of the wireless communications modules to a single unit for manipulating the RF signals; and controlling the unit for manipulating RF signals to connect an RF signal of a selected one of the wireless communications modules to the antenna subsystem. The unit for manipulating RF signals may perform various kinds of RF signal processing or conditioning. Furthermore, the antenna system may include a phased array antenna. Besides portable computers such as laptop, notebook and netbook computers, the same principles are applicable to mobile electronic devices generally, including cellphones for example.
