Sample 1. Wireless broadband network layout diagram.
A wireless wide area network (WWAN), is a form of wireless network. Wireless networks of all sizes deliver data in the form of telephone calls, web pages, and streaming video.
A WWAN often differs from WLAN by using mobile telecommunication cellular network technologies as LTE, WiMAX, UMTS, CDMA2000, GSM, cellular digital packet data (CDPD) and Mobitex to transfer data. [Wireless WAN. Wikipedia]
