 Market Challenges:

The highway is a major hub for national traffic arteries, the greater traffic flow, some sections of the current actual traffic volume has exceeded the design capacity. Among them are free parking, overtaking, ultra high-speed, low-speed driving, overloading driving and other illegal acts seriously jeopardize the safety of the highway open. Due to the continuous extension of the highway, a serious shortage of high-speed traffic police force, various aspects of the problem remains outstanding, followed the traditional mode of communication in the past, can not meet the needs of the new situation of public security traffic management. Therefore, the urgent need clear and reliable police on the highway with a wireless communication system to support command scheduling, which is the most basic business requirements. The high-speed communication at this stage the following problems:

1, Transit stations covering a limited range, in the disposal of a major accident or major security guards work, transit small station communication range, the command center was unable to relevant sections of unified command and dispatch, police officers use walkie-talkies to be used in different sections of different channels, easily missed instruction.

2, The high cost of network building cluster system, use is not convenient enough, poor voice quality can not be resolved during the call that appears across the base, broken words and other issues.

New international and domestic situation of public security work put forward new demands to "pull a move" on the highway you can always create a wireless emergency communications; requirements "pass was the" done at any place, any time guaranteed smooth, high-speed communications command center at all times be able to contact the police in any area with high speed; requirements "see clearly", ready to capture live images, and promptly transmitted to the command center levels. Rely on scientific and technological progress to make a communication solution for highway police and control center.


Combined with practical communications applications demand high-speed traffic, well-informed developed a wireless audio and video dispatching solution program construction using the following principles:

the TID active exploration, innovation, based on China telecom, China unicom, China mobile's 2G and 3G, 4G network application function cluster intercom is developed to help law enforcement team to improve the overall efficiency.

Cluster intercom business is based on the China telecom, China unicom, China mobile's 2G and 3G, 4G network wide coverage, large capacity of the mobile communication network and operator level of business management platform, command scheduling management platform, using the Push to Talk (PTT, a key) technology, through professional talkback terminals with the function of PTT, providing customers with intercom business within the scope of the mobile communication network coverage.
