Wireless Communications & Networking
During the past three decades, the world has seen signifi cant changes in the telecom-<br />
munications industry. There has been rapid growth in wireless communications, as<br />
seen by large expans

Two of the major developments reshaping the telecommunications landscape are<br />
mobile wireless connectivity and the migration of voice telephone services to IP<br />
technology. Those two ideas co
Utility Maximization in Nonconvex Wireless Systems
Once upon a time, cellular wireless networks provided two basic services: voice<br />
telephony and low-rate text messaging. Users in the network were separated<br />
by orthogonal multiple access sch

Telecommunications is today widely understood to mean the electrical means of<br />
communicating over a distance. The first form of telecommunications was that of<br />
the Telegraph, which was inven

Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor<br />
UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding<br />

The continuing explosive growth in mobile communication is demanding more spectrally<br />
efficient radio access technologies than the prevalent second generation (2G) systems such as<br />
GSM to ha
Transmission Techniques for 4G Systems
Fourth Generation (4G) wireless communication systems aim to allow peak data<br />
rates in the range of 1 Gbps for nomadic access and 100 Mbps for vehicular mobil-<br />
ity. 4G aims to support curre
Time-Varying Channels
Wireless communications has become a field of enormous scientific and economic interest. Recent<br />
success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless<

The Complete Wireless Communications
When thinking about mobile radio engineers there is a tendency to<br />
assume that the engineering function relates solely to the technical<br />
aspects of the network, such as the equipment design
The 3G IP Multimedia Subsystem (IMS)
When 3GPP started standardizing the IMS a few years ago, most analysts expected the<br />
number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were<br />

Telecommunications Modeling
A mobile ad-hoc network (MANET) is formed by multiple moving nodes<br />
equipped with wireless transceivers. The mobile nodes communicate with<br />
each other through multi-hop wireless links, where

Stochastic Geometry and Wireless Networks
A wireless communication network can be viewed as a collection of nodes, located in some domain, which<br />
can in turn be transmitters or receivers (depending on the network considered, nodes may be
