The number of subscribers for mobile communications has increased much faster than predicted. The majority of traffic is changing from speech oriented communication to multimedia communication with the support advanced and wideband services including e-mail, file transfers and distribution services like radio, TV and software provisioning.
4g Mobile Communications Wireless Mobile Communications PPT focuses on the data-rate increase and new air interface.4G Mobile that converge the advanced wireless mobile communications and high-speed wireless access systems into an Open Wireless Architecture (OWA) platform.
Based on this OWA model, 4G mobile will deliver the best business cases to the wireless and mobile industries that is cdma2000/WLAN/GPRS 3-in-1 product, WCDMA/OFDM/WLAN 3-in-1 product, etc. Asia-Pacific is the dynamic market of new generation mobile communications with over $100 Billion businesses in the next decade.
The 4G mobile technology, convergence of wireless mobile and wireless access, will definitely drive this growth. The wireless system such as 3G, HSDPA, WiMax, etc., will be replaced by open wireless architecture system very soon and can be integrated and converged on this open platform.
The advent of 4G wireless systems created various research opportunities. The expectations with 4G are high with respect to data rates, spectral efficiency, mobility and integration.
Orthogonal Frequency Division Multiplexing (OFDM) is proving to be technology to be used in 4G. ATLAB to generate the OFDM signal proves that clipping does reduce Peak to Average Ratio.

Conclusion:
The first operational cellular communication system provided voice transmissions. The second generation (2G) of the wireless mobile network used low-band digital data signaling which is known as Global Systems for Mobile Communications (GSM). The objective of the 3G was to develop a new protocol and new technologies. The 4G framework established to accomplish new levels of user experience and multi-service capacity like GSM – Global System for Mobile Communications, GPRS – General Packet Radio Service, IMT-2000 – International Mobile Communications, Wi-Fi – Wireless Fidelity, Bluetooth. 4G networks have following properties: Ubiquity, Multi-service platform, and Low bit cost.
