Chapter 1 Cisco MWR 2941 Router Overview
Introduction
Cell Site Points-of-Presence
The cell site becomes a physical Point-of-Presence (POP) from which to offer hotspot services, or voice
and wired ISP services, to nearby enterprises and residences. Because many cell sites are located in and
around downtown areas, hotels, airports, and convention centers, they make attractive sites for
co-locating public wireless LAN (PWLAN) access points and other wireless data overlays. Many of
these wireless data radios are IP-based. IP networking features, like Mobile IP, VoIP, IP Multicast, VPN,
and content caching, enable delivery of new revenue-generating services over these radios. The
corresponding traffic “rides for free” on the spare backhaul bandwidth (Figure 1-1).
