WiMAX simply leaps over these barriers, allowing a virtually unlimited number of video surveillance cameras to be deployed quickly, easily
Figure 5.8 Security and surveillance applications
and cost-effectively in a new or expanded security system. High-resolu-tion, real-time video from each security camera is transmitted directly to a WiMAX base station in the on-site security office or regional security centre. From here, the wireless network can remotely control the cameras (Figure 5.8).
Wireless video surveillance is a cost-effective, flexible and reliable tool for monitoring traffic, key roads, bridges, dams, offshore oil and gas, military installations, perimeter, borders and many more critical locations. Wireless video surveillance can also be used for special events as backhaul is easy and not time-consuming.
Further support for nomadic services and the ability to provide ubiquitous coverage in a metropolitan area provides a tool for law enforcement, fire protection and other public safety organizations, enabling them to maintain critical communications under a variety of adverse conditions. Private networks for industrial complexes, universities and other campus type environments also represent a potential business opportunity for WiMAX.
Because of its flexibility, WiMAX can provide a wide range of options from economical solutions for campus and mall security to mission-critical regional homeland security systems spanning thousands of square miles.
Multimedia Communication
IP-based wireless broadband technology can play an important role in delivering multimedia communication, information and entertainment
that subscribers are demanding, with convenient access at any time and any place. Video chat and video conferencing are two such services, but with different quality and features.
Sensor Networks
Most mesh network applications, especially in the commercial sector, focus on traditional PC-based computing. However, researchers are also interested in using mesh network technologies to create networks of autonomous sensors - small devices that can be installed in a variety of locations to provide readings on temperature, air quality and other factors.
By incorporating a wireless chipset with mesh networking software, these sensors can become network-aware. After they are installed and powered on, the sensors can join a mesh network and make their data accessible to others on the network. In many situations, both in buildings and outdoors, installing small mesh-enabled sensors in many locations will be far preferable to setting up network cabling to connect the sensors or (worse) manually collecting data from the sensors.
Telematics and Telemetry
Telematics, the combination of telecommunications and computing, is predicted to be the next growth area in automotive electronics.
The use of automotive telematics in ‘e-vehicles’ that have audio email and web-browsing, DVD, digital TV and radio, as well as route guidance and traffic avoidance information, is predicted to grow to more than 11 million subscribers by 2004 in the USA.
A related technology, telemetry does not have such predictions. The Formula 1 (F1) sport utilizes telemetry to beam data related to the engine and chassis to computers in the pit garage so that engineers can monitor that car’s behaviour. Bidirectional telemetry, from car-to-pit and pit-to-car, was allowed for a short while a few years ago. Bidirectional telemetry enables teams to alter settings on the governing electronic control unit by radio signal, and this can mean the difference between victory and defeat. However, car-to-pit telemetry is currently banned.
Many More
Some more disruptive applications of WiMAX can be:
• Remote monitoring of patients’ vital signs in health-care facilities to provide continuous information and immediate response in the event of a patient crisis.
• Mobile transmission of maps, floor layouts and architectural drawings to assist fire-fighters and other response personnel in the rescue of individuals involved in emergency situations.
• Real-time monitoring, alerting and control in situations involving handling of hazardous materials.
• Wireless transmission of fingerprints, photographs, warrants and other images to and from law-enforcement field personnel.
WiMAX Impact
Wireless broadband access to the Internet has recently witnessed explosive growth. Much of this growth has come from the rise of wireless networks. Wireless networks today are being widely used in markets such as education, healthcare, manufacturing, retail, hospitality, government and transportation.
A new wireless network transition is gathering momentum in the shadow of the accelerating trend in wired broadband. The rapid growth of wireless infrastructure has generated an interesting set of problems for operators, users and regulators. Traditional operators have been forced to consider multiple business models to generate viable revenue streams.
