Disaster Recovery In case of accidents due to fire, floods or other disasters, the loss of communication infrastructure in wireless communication system can be minimal. Types of Wireless Communication Systems Today, people need Mobile Phones for many things like talking, internet, multimedia etc.
Commercial applications include monitoring of fire hazards, hazardous waste sites, stress and strain in buildings and bridges, carbon dioxide movement and the spread of chemicals and gasses at a disaster site. During this process, a small amount of redundancy is introduced to the signal so that it becomes robust against noise.
Despite the big data rate differences, wireless LANs is becoming the preferred Internet access method in many homes, offices, and campus environments due to their convenience and freedom from wires. These Electromagnetic Waves propagates through space.
These wireless sensors self-configure into a network to process and interpret sensor measurements and then convey this information to a centralized control location.
These topics include: the wireless vision, generations of wireless, technical issues, current wireless systems, wireless LaNs, Wide Area Wireless Data Services, Broadband Wireless Access, Satellite Wireless Access, Satellite Networks, and Bluetooth and this material will stimulate you to do more research in these various areas of the wireless industry.
The redundant bits from the message are removed using the Channel Decoder. The individual signals are demodulated using appropriate Demodulation Techniques and the original message signal is recovered. Wide Area Wireless Data Services Wide area wireless data services provide wireless data to high-mobility users over a very large coverage area.
The network architecture used a star topology with the central computer at its hub. Data rates of around 40 Mbps will be available for fixed users and 15 Mbps for mobile users, with a range of several kilometers.
