Chapter 7Networking and Services Aspects of Broadband Wireless

So far in Part II of this book, we have discussed only the air-interface aspects of broadband wireless networks. In particular, we have discussed physical (PHY)-layer techniques to transport bits over the air at high rates, and media access (MAC)-layer techniques for sharing the available radio resources among multiple users and services. Those aspects are definitely among the most critical and challenging ones for broadband wireless system design, and, in fact, most of IEEE 802.16e and WiMAX specifications deal with those aspects. But from a standpoint of delivering broadband wireless services to end users, there are several other aspects and challenges that require consideration. ...
