Roaming in Wireless Networks (Communications Engineering)

Roaming in Wireless Networks (Communications Engineering), 9780071455053 (0071455051), McGraw-Hill, 2005

Mobility is the key to the success of wireless networks. Roaming has extended the definition of mobility beyond the technology, network, and country boundaries. Is not it fascinating to make or receive calls anywhere in the world using the same phone and identity? International roaming is already proven to be one of the most popular features of today’s wireless network. With the advent and widespread deployment of GSM technology, the mobile users have flexibility to use services in more than 500 networks. Inter-standard roaming has also made significant progress in recent years. Roaming capability in GPRS and 3G networks is progressively being implemented. The convergence of wireless mobility with Wi-Fi/WiMax is on card. The day is not far when a mobile user will be able to seamlessly roam anywhere regardless of the network, location, and device.

Interworking technology and operation and the business processes that enable roaming are complex. The main purpose of this book is to provide readers a comprehensive overview of roaming implementation, architecture, and protocols and its evolution from voice roaming in GSM to data roaming in GPRS and 3G networks. It can also be used as a guidebook to those who are responsible for roaming testing, maintenance, and management.
