Joining the UDCP is beneficial to inter-departmental collaboration. CAS and HKPF carry out numerous joint exercises every year. In a recent one in Ngong Ping 360, all officers involved tuned their communications channel to the UDCP common talk group, which instantly connected everyone and enhanced efficiency of the exercise.
With the use of digital transmission, the coverage of the UDCP’s radio signals is up to 95%. In January this year, Hong Kong was hit by the most severe cold surge in 60 years. Many people who went up Tai Mo Shan for frost viewing were stranded there due to bad weather. CAS and other government departments were involved in the rescue operation. Tai Mo Shan is a remote mountain, hardly covered by ordinary mobile phones and communications facilities. Using the portable transceivers of the new system, officers of CAS enjoyed seamless communications with excellent sound quality, which greatly enhanced the efficiency of the rescue work.
Communications over the UDCP are encrypted to prevent tapping and to strengthen call security. The new system is equipped with devices which are light and easy to carry. By configuring the portable transceivers to be compatible with the UDCP and without setting up extra fixed or temporary repeater sites, CAS officers can enjoy reliable and radio communications with wide coverage. The new system also helps CAS save manpower and maintenance expenditure, thus achieving cost-effectiveness.
