General Packet Radio Service (GPRS) is a complex data network which upgrades current second generation GSM networks, offering true high-speed internet (IP) and network connectivity over existing GSM cellular networks. The increasing population of mobile users leads to congestion problems in these systems, and motivates the development of more efficient management schemes. This project deals wit...

In cellular mobile radio systems, the directional inhomogeneity of the mobile radio channel can be exploited by smart antennas to increase the spectral efficiency. In this paper, a novel smart antenna concept applying receiver antenna diversity at the uplink receiver is investigated for a time-slotted code-division multiple-access (CDMA) mobile radio air interface termed time-division CDMA (TD-...

48 ellular digital packet data (CDPD) [1–3] networks provide wireless data communications services to mobile users by sharing the radio equipment and unused RF channels with Advanced Mobile Phone System (AMPS) networks [6]. Basically, CDPD transmits packet data over idle AMPS channels, and autonomously switches to another channel when the current channel is about to be assigned for voice usage....

The ongoing evolution of wireless cellular networks is creating a new ecosystem with pervasive presence of a great variety of network-enabled objects which, based on unique addressing schemes, are able to interact with each other. Cellular connectivity is reaching beyond smartphones and tablets, providing access to data networks for connected home appliances, machinery and vehicles. The rapid e...

Radio fingerprinting is the process which identifies a cellular phone / other radio transmitter by the unique "fingerprint" which characterizes the signal transmission. Location fingerprinting determines receiver position with the help of database of RSS measurements from different sources .Location fingerprinting a positioning method that explores existing infrastructures e.g. cellular network...

networks and services, fueled by next-generation mobile communications systems research, has ushered in the era of ubiquitous computing. Lightweight portable computers, IP-based (office and home) appliances, and the popularity of the Internet are providing strong incentives to service providers to support seamless user mobility. Realizing commercially viable IP mobility support over the current...

In this paper, we present ICEPT, a new mobile radio network planning tool that is based on an integrated design approach. The new approach starts with the analysis of the spatial distribution of the expected teletra c within the service area of the cellular system. Employing this principle, the ICEPT tool considers concurrently the four major design areas of cellular networks: Radio Transmissio...

The rapid evolution of cellular technology and the augmentative user demand for advanced mobile services leads the industry to develop more efficient network structures. The increasing number of cellular users and the demand for broadband mobile communications (3 and 4 generation) drives to the research of new methodologies for the design of cellular networks and services. Simulation environmen...
