information between the sender and receiver. While many people think of communication primarily in oral or written form‚ communication is much more. Communication can be done in many forms either as verbal or non-verbal‚ such as body language‚ sign language‚ touch and eye-contact. 2.1. Types of Communication. The purpose of communication is to get the message across to others. This is a process that involves both the sender of the message and the receiver. By successfully getting your message

CHAPTER 1 INTRODUCTION In this project‚ the wifi hotspot is implemented using HSDPA because of its features like Hybrid ARQ ‚ Adaptive modulation and coding‚ High speed downlink shared channel. This features enhance wifi hotspots to support an evolution towards more sophisticated network and multimedia services‚ the main target of HSDPA is to increase user peak data rates‚ quality of service‚ and to generally improve spectral efficiency for downlink asymmetrical services. HSDPA can achieve

narrower bandwidth than FM‚ and wider coverage compared with FM radio. The major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference. Also‚ although the radio transmitters can transmit sound waves of frequency up to 15 kHz‚ most receivers are able to reproduce frequencies only up to 5kHz or less. Wideband FM was invented to specifically overcome the interference disadvantage of AM radio. A distinct advantage that FM has over AM is that FM radio

Broadcast Protocol Handler (RBPH) is a reliable multicast transport protocol mainly aimed for applications that require ordered‚ duplicate-free‚ multicast data delivery from multiple sources to multiple receivers. The advantage of RBPH over traditional multicast protocols is that it guarantees that a receiver in the group either receives all data packets from transmissions and retransmissions‚ or is able to detect unrecoverable data packet loss. RBPH is specifically intended as a workable solution for multicast
