Along with the explosive growth of smart phones, a new wave of the mobile device development is on the way, in which the WiFi enabled cellular phone has been taking an extremely important position. Unlike the desk top PC and notebook computers, integrating the WiFi radio within a cellular phone is much more complicated and challenging than simply putting two systems in a box with the form factor of a cellular phone. This paper will discuss the technical challenges and solutions regarding the integration of WiFi and cellular phone systems. Several examples of the WiFi front end module (FEM) will be given.
