Cellular Network Architecture:

Learn how cellular networks are structured, with individual cells forming a network. Each cell is served by a base station, similar to an 802.11 Access Point (AP), facilitating mobile device connections. The base station and mobile devices communicate via an air interface employing both physical and data link layer protocols. The Mobile Switching Center (MSC) manages mobility, handles call setup, and connects cells to a wide-area network (WAN).

Radio Spectrum Sharing:

Discover the methods used to share limited radio spectrum between mobile devices and base stations. Learn about:

• Combined FDMA/TDMA
• CDMA
