In recent years, the global disasters occur frequently, Indonesian tsunami, Sichuan Wenchuan earthquake, Haiti earthquake, and Yushu earthquake that is making many people anxious not only caused great loss of the State, society, while the public network paralyzed. At this time, the professional wireless communication system and interphone become the most effective communication for emergency protection.

However, the traditional simulation trunking used more frequently in China is of inherent shortage of low spectrum utilization ratio, small system capacity, single business functions, poor security confidentiality etc deficiencies, other international figures standards are again of little coverage, expensive networking cost, difficult to be compatible with simulation system and foreign intellectual property barriers etc issues. China’s public security industry needs a new digital trunking standard with independent intellectual property rights and suitable to digital transformation for domestic public safety simulation system.

On August 4, 2008, the Information and Communication Bureau under the Ministry of Public Security chaired to hold the seminar for police wireless communications digital development strategy in Shenzhen, founding a project Expert Committee, and the domestic manufacturers represented by the Hytera formulated the next generation public security digital trunking standard, which is the birth of PDT. It is based upon China’s public security market, considering different users’ demand at county level, municipality level, province level, and national level as well as the network actual construction need.

Its appearance will promote the development speed and strength of domestic police communications industry, will also bring more suitable communication solutions and equipment to the public security system. ”

It is reported that as the world's very few first to master the professional wireless communications PDT, TETRA and DMR digital technology manufacturers, Hytera Communications authorized by the Ministry of Public Security, as a leading unit (Vice President) to formulate the standard of the Chinese police digital trunking interphone, actively participated in the formulation of China’s PDT standards and development of products, and provided a range of solutions of quality digital trunking system for the domestic public security customers.

Along with continually upgrading the strength of Chinese local professional wireless communication companies and expanding their marketing network, the communications of Chinese public safety systems will be guaranteed by terminals, systems, solutions of more high-quality, high safe information, and thus to better safeguard social stability, all are of a significance on protection of national economic sustained and healthy development.
