Wireless Digital System
WiMAX is wireless digital system also known as IEEE 802.16. It is an IP based wireless broadband technology that offers same functioning to Wi-Fi and cellular networks. It stands for Worldwide Interoperability for Microwave Access.
During past research it calculated 30 to 40 megabit-per-second data rates but the new research in 2011 proposed the speed up to 1 Gbit/s for fixed stations. WiMAX has the capacity to deliver broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 – 10 miles (5 – 15 km) for mobile stations. In comparison with, the WiFi is restricted to only 100 – 300 feet (30 – 100m).
WiMAX – A Substitute To Cable And DSL
The name “WiMAX” was invented by the WiMAX Forum, the forum was formed in June 2001 to encourage conventionality of the standard. The council defines WiMAX as a technology based on standards permitting the delivery of last mile wireless broadband retrieval as a substitute to cable and DSL.
WiMAX activates on equally licensed and non-licensed frequencies, and hence provide a controlled environment and feasible economic model for wireless carriers.
WiMAX Allows The Adoption Of Advanced Radio Traits
WiMAX is a universal initiative. Its function is to confirm that the broadband wireless radio manufactured for customer use interoperate from seller to seller. The main plus points of the WiMAX standard are to allow the adoption of advanced radio traits in an even way and diminish costs for all of the radios made by companies. Now-a-days a recent term Long Term Evolution (LTE) standard is like term depicting a parallel technology to WiMAX that is established by vendors and carriers as a counterpoint to WiMAX.
Closed Circuit Television Cameras
Closed circuit television cameras (CCTV cameras) can produce images or recordings for surveillance and use of WIMAX technology in CCTV cameras helps to communicate, covering many kilometers, to deliver network to a connection through internet.
CCTV cameras are installed either behind the wall, on the traffic signals, or any desired place where security issues has to be maintained.
WIMAX In CCTV Cameras
Here is an example that explains the role of WIMAX in CCTV cameras.
A CCTV camera can be fixed on track near train station using WIMAX technology for association to the train. CCTV camera takes pictures from hazardous points of crossings, furthered straightforward send the pictures to the train engineer, permitted him to forestall any possible obstacles on the track former to reaching the actual station.
SO, security cameras with WIMAX technology is widely use to avoid any sort of damage, loss and insecurity and provide:
- High image resolution
- Two way audio way a single network cable
- Transmission of commands
