Wireless Broadband Access Organisation
Purpose
Wireless broadband access (WBA) is advanced information technology implemented in communication systems and general and special purpose data transmission networks. WBA technology is based on the theory of broadband signals, designed for jam-resistant transmission of information using low-power signal.
The main idea behind WBA technology is that a significantly greater bandwidth is used for data transfer than the one required during normal transmission, and optimal signal processing is applied to the receiving path. Due to the redundancy of the bandwidth and the optimal processing of the received signal a high value of the signal-to-noise ratio at low-power transmitted signal is provided. This allows using as part of WBA equipment transceivers of significantly lower power capacity, and, as a consequence, of smaller size and lower cost.
Features
WBA unites the communications provider -level technology and “last mile” communication technology, which ensures versatility and improves the reliability of the system as a result.
Networks built on WBA-based technologies are highly flexible, easy to set up and can be easily scaled if it is necessary. WBA technology is initially focused on the use of the IP protocol. That allows you to easily and transparently integrate them into the local networks. WBA networks are simple in deployment. Simplicity of installation is a major cost reducing factor of network deployment in remote areas. WBA technology is suitable for stationary as well as mobile objects of WBA networks on a single infrastructure. Use of traffic encryption means, user authentication and other algorithms provide a reliable and SECURE connection.
Communication networks and channels
Objectives:
- Construction of local communication networks of airports and ATC centers;
- Organization of stand-by communication networks (channels);
- Binding of airports and ATC centers to “access points” of baseline networks;
- Organization of communication (channels) netwroks in areas with challenging terrain;
- Organization of channels of information and technical cooperation between ATC with national security contol centers.
List of channels organized in WBA networks:
Voice communication channels of control centers of ATC centers and airport;
Channels of radar data transmission and direction finding information;
Channels of collection and transfer of meteorological data;
Aeronautical fixed telecommunication network (AFTN);
Broadcasting lines of VHF and HF radio communcation to receptaion adn transmission centers;
Communication lines of control and monitoring systems of radio-technical flight support and communication means operation;
Telecommunication channels of ATC center;
Binding lines of ATC centers to operator communication centers («last mile» technology);
Data transmission channels of local area network (LAN) of ATC center;
Fire and security alarm channels;
Channels of data exchange with operational control centers.
