mise significantly higher data rates (up to 2 Mbits/sec) and a new array of mobile communication services, such as video teleconferencing and web browsing. Full interoperability (global roaming) of 3G mobile systems is now a possibility as a result of the international IMT-2000 standardization effort. In November of 1999, a comprehensive set of radio interface specifications for IMT-2000 was approved. The five required interfaces enabling interoperability are IMT-DS (Direct Spread), IMT-MC (Multi-Carrier), IMT-TC (Time Code), IMT-SC (Single Carrier), and IMT-FT (Frequency Time). 3G field trials are currently underway with plans to begin commercial operation in 2001.
NIST has been involved in 3G systems since 1998. At that time, there were 16 radio technology proposals for IMT-2000. NIST WCTG selected two of the more promising proposals to follow, and began analysis and modeling. Those two proposals, UTRA (W-CDMA) and cdma2000, were selected in Nov. 1999 to make up three of the five IMT-2000 radio interfaces. NIST's role in this work is not going to be limited to 3G wireless systems. It will be an ongoing effort for next generations of wireless technology.

Wireless Communication Systems MSc
The evolution of wireless communication systems and networks in recent years has been explosive. This is a global phenomenon, which presently is outstripping the ability of commercial organisations to recruit personnel equipped with the necessary blend of technical and managerial skills who can initiate and manage the introduction of the new emerging technologies in networks and wireless systems. The effect of this current trend has been a growing overlap of the network and communication industries, from component fabrication to system integration. Another result is the development of integrated systems that transmit and process all types of data and information.
The aim of this course is to develop a strong theoretical background involving the future of wireless communication systems. It will also develop a detailed technical knowledge of current practice in wireless systems and networks. It is a distinctive course that is not taught anywhere else in the UK. You will benefit from both a theoretical and practical grounding in the course due to the availability of a fully working wireless laboratory in the School, allowing students to develop their skills in this field. The lab was established as a direct result of research in this field.
The flourishing market place for mobile networks has meant that the telecommunication companies (Vodafone, O2, etc) are making their largest profits from this sector of industry. Therefore demand for jobs and for trained engineers to fill those jobs remains very high.
The connectionless office is also a new trend for creating flexible working areas within companies and organisations and the demand for wireless engineers in this domain is expected to be very high in the future. The continuing trend of convergence of services and networks mean that a lot of new industries and research institutions are looking into integrating satellite, mobile and GPS networks.
Taught Modules
The course is comprised of the following modules:
1. Advanced Digital Comunications
2. Wireless Network Technologies
3. Advanced Mobile Systems
4. Satellite and Optical Communications
5. DSP for Communications
6. Wireless Communication Security
7. Project Management
8. Wireless Communication Workshop
9. Dissertation

Wireless communication
Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires".[1] The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). When the context is clear, the term is often shortened to "wireless". Wireless communication is generally considered to be a branch of telecommunications.
It encompasses various types of fixed, mobile, and portable two way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice, keyboards and headsets, satellite television and cordless telephones.
* g pressed on the controller to the main console which then processes this information and makes it happen in the game. All of these steps are completed in milliseconds.
Wireless networking (i.e. the various types of unlicensed 2.4 GHz WiFi devices) is used to meet many needs. Perhaps the most common use is to connect laptop users who travel from location to location. Another common use is for mobile networks that connect via satellite. A wireless transmission method is a logical choice to network a LAN segment that must frequently change locations. The following situations justify the use of wireless technology:
* To span a distance beyond the capabilities of typical cabling,
* To avoid obstacles such as physical structures, EMI, or RFI,
* To provide a backup communications link in case of normal network failure,
* To link portable or temporary workstations,
* To overcome situations where normal cabling is difficult or financially impractical, or
* To remotely connect mobile users or networks.
Wireless communication can be via:
* radio frequency communication,
* microwave communication, for example long-range line-of-sight via highly directional antennas, or short-range communication, or
* infrared (IR) short-range communication, for example from remote controls or via IRDA.
Applications may involve point-to-point communication, point-to-multipoint communication, broadcasting, cellular networks and other wireless networks.
The term "wireless" should not be confused with the term "cordless", which is generally used to refer to powered electrical or electronic devices that are able to operate from a portable power source (e.g. a battery pack) without any cable or cord to limit the mobility of the cordless device through a connection to the mains power supply. Some cordless devices, such as cordless telephones, are also wireless in the sense that information is transferred from the cordless telephone to the telephone's base unit via some type of wireless communications link. This has caused some disparity in the usage of the term "cordless", for example in Digital Enhanced Cordless Telecommunications.
In the last fifty years, wireless communications industry experienced drastic changes driven by many technology innovations.
