To date, the standard has been ratified by The Ministry of Public Security of the People’s Republic of China. In addition, the PDT alliance is active in bolstering PDT’s status as a Chinese national standard. The alliance is aiming to promote the PDT standard worldwide, making it one of the world-leading digital trunking standards. The Phase II PDT standard will focus on increasing data transmission rates and providing broadband service applications.
Led by China's Ministry of Public Security, Hytera, the general technology leader, has joined other domestic manufacturers in drafting the PDT standard. The PDT alliance comprises members, such as Hytera, Youneng, Sichuan Weide, Guangzhou Weide, Wange Communications, Tianlitong, NTC, and Xun’an Network System.
1. Market Positioning (Applicable Industries)
The PDT standard is suitable for sectors, such as public security, emergency communications and public utilities.
2. Main Features
The PDT standard operates in the TDMA (double time slots) multiple address mode and supports 12.5 kHz channel interval, 4-frequency shift keying (FSK) modulation, and a data transmission rate of up to 9.6 KB/s. In addition to basic services, the standard integrates a range of innovative functions, such as simulcasting and dynamic frequency resource management. The Phase II PDT standard will focus on increasing data transmission rates and providing broadband service applications.
Oriented to China's police market, the PDT standard addresses varied user and network construction requirements at county, municipal, provincial and national levels. In addition to supporting low-cost system communications over a single base station, the standard delivers efficient macro-cell coverage to suit the construction of a nationwide 4-level emergency communications network for public security use. The technology provides rapid access to the existing police-intended global information system (GIS) dispatching platform in response to emergencies, such as earthquakes, typhoons, and public security incidents. It features flexible networking, efficient commanding and dispatching, and high quality voice and data transmission to deliver rapid responses and a high security level.
The PDT standard can fully utilize spectrum resources. Working in macro cell networking mode, the technology supports smooth evolution from analog MPT1327 to digital trunking. The standard provides a wide range of services, strong scalability and backward compatibility. Mover, the technology allows for low-cost systems and terminals and supports swift network construction and cost-effective operation and maintenance (O&M). Overall, the PDT standard is highly competitive in the field of wireless communications. With proprietary encryption technology, the standard is ideal for the public security sector.
