WCDMA for UMTS HSPA Evolution and LTE
Second-generation telecommunication systems, such as the Global System for Mobile<br />
Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones<br />
exceeds the number
Understanding_the_Basics_of_MIMO
An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals<br />
simultaneously through multiple antennas, while still utilizing a single radio channel. This i
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 />
ready (3GPP Re
Tactical+Wireless+Communications+and+Networks
Before I can present design concepts or tactical wireless communications and network<br />
challenges, I feel the need to mention the challenges of writing for a field where some<br />
