I recommend the book for people who want to learn more about the design for the Radio Access Networks (RAN).

The book's goal is to provide information on the current and near future state of mobile networks and its evolution to all IP based mobile network. It discusses the key technology trends and concepts for mobile network but it does not provide any recommendation on which technology is the best.

The book assumes that the readers have at least intermediate or advanced level of knowledge on Internet Protocol (IP) and other network technologies such as IP addressing, dynamic routing, multicast, BGP, MPLS, 802.11 wireless networking and basic understanding of Radio Access Networks (RAN). It is mainly written for network engineers looking to design, implement or understand the technology concepts and trends for mobile network.

The book starts with chapter introducing various basic radio technologies such as propagation, modulation, radio degradation mitigation and different access technologies such as TDMA (time division), FDMA (frequency division), CDMA (code division) and the new SDMA (space division). The last one is an emerging technology using the publicly familiar Multiple-Input Multiple-Output (MIMO) techniques, to increase throughput and coverage.

Then the book jumps into detail discussing the concepts, architecture and performance aspects of various cellular access systems from the legacy Global System for Mobile (GSM), Wideband CDMA (WCDMA) to the current 3G technologies such as High Speed Downlink Packet Access (HSDPA) and Evolution Data Only (EVDO).

The next chapter discusses the future evolution of mobile network to adopt all IP access systems that include Microwave Access (WiMAX) and Long Term Evolution (LTE) which is marketed as 4G system technologies that can support 100 Mbps throughput for mobile users. This chapter also describes how the mobile network uses tunneling with encryption to deliver data to mobile user end system without exposing their network core to the internet. This is quite a challenge since mobile IP hosts frequently moves from one routing domain to another.

The last few chapters discuss IP connectivity and evolution to IP based core mobile network and Intelligent Network (IN) which can enforce traffic policies (think QoS) based on subscriber, device or application and the evolution of the framework to IP Multimedia Subsytem (IMS) which allow end to end context awareness to launch services such as VoIP, video delivery and others.
