4g technology paper presentation ppt

4g tutorial ppt

It is compatible with, and independent of the underlying radio access technology. Provides mobility in internet access. Hence there is optimum usage the available bandwidth.

advantages and disadvantages of 4g technology pdf

But in wireless ad hoc peer-to-peer networks, users cooperate - rather than compete - for network resources. The generation of technologies provides us the best services to stay connected to the outer world. An all IP-based 4G wireless network has inherent advantages over its predecessors.

Provides support high definition videos.

4g technology ppt

This will provide uniform video, voice, and data services to the mobile host, based entirely on IP. Wireless mobile communications systems are uniquely identified by "generation designations.

4g vs wifi presentation

Because technology costs tend to decline over time, a current viable business model should only become more profitable over time. Today, wireless communications are heavily biased toward voice, even though studies indicate that growth in wireless data traffic is rising exponentially relative to demand for voice traffic. An all IP-based 4G wireless network has inherent advantages over its predecessors. OFDM is orthogonal frequency division multiplexing. Let us now learn about 4G. As people congregate and create pockets of high demand, they also create additional routes for each other, thus enabling additional access to network capacity. Provides support high definition videos. Companies using 4G technology cellular companies Alcatel, Nortel, and Motorola.

Internet has become part of our day to day life and we need it to stay connected to outer world. WHY 4G?

Evaluation of 4g technology

The high performance is achieved by the use of long term channel prediction, in both time and frequency, scheduling among users and smart antennas combined with adaptive modulation and power control. OFDM is basically used for high rate of data transfer. It was deployed in year The problem with 3G wireless systems is bandwidth-these systems provide only WAN coverage ranging from kbps for vehicle mobility applications to 2 Mbps for indoor static applications. An IP wireless network replaces the old Signaling System 7 SS7 telecommunications protocol, which is considered massively redundant. As people congregate and create pockets of high demand, they also create additional routes for each other, thus enabling additional access to network capacity. An all IP-based 4G wireless network has inherent advantages over its predecessors. Introduced in the early s, first generation 1G systems were marked by analog frequency modulation and used primarily for voice communications. Companies using 4G technology cellular companies Alcatel, Nortel, and Motorola. Because users carry much of the network with them, network capacity and coverage is dynamically shifted to accommodate changing user patterns.
