 DAB+  Band III Hong Kong's terrain is mountainous and difficult to cover completely. The existing FM network requires 7 sites, each with its own frequency, for each of the 7 FM services - 49 frequencies! DAB's single frequency network offers an obvious long-term saving, not only in spectrum but also in hardware and energy consumption. DBC aims to achieve 95% coverage of the SAR as a whole, the remainder being on outlying islands. Negotiations are reported to be underway with mainland authorities to co-ordinate an increase of transmission power to ensure good indoor reception in the areas covered.

The government has mandated DAB+, enabling both commercial radio services, and those of RTHK to be carried on a single multiplex. The government has set minimum criteria for bitrates - 32 kbit/s for speech services, and 48 kbit/s for music, but allows the service providers some flexibility in how they use their capacity, which will be allocated as a block.

It is understood that the Band III ensemble in Guandong province on the mainland is sometimes receivable in the west of the territory. This was not achieved when attempted November 2011. There used to be T-DMB transmissions in Shenzhen, that Wohnort was able to receive in the areas of the New Territories closest to the border, such as Sheung Shui.

A DAB+ radio is definitely required in order to receive digital radio in Hong Kong. Only a T-DMB receiver would be able to receive the programmes from the mainland.

 DMB-TH thumbnail The Office of the Telecommunications Authority has allocated by auction the UHF frequency (Ch 47) for broadcast mobile TV. From three bidders, the licence will be issued to the winning applicant, China Mobile Hong Kong Corporation Limited. Wohnort expects the Chinese system known as DMB-TH (not a member of the DAB - Eureka 147 family) will be used. A number of HK sites have been co-ordinated with the Mainland to use this frequency. The other bidders were:-
City Telecom (H.K.) Limited
Hong Kong Telecommunications (HKT) Limited

Hong Kong multiplex operator and broadcaster DBC is kick-starting the DAB+ radio market with a collection of inexpensive, own-brand models. Offered in a variety of shockingly vivid colours (a theme throughout the DBC studio centre), the radios are intended to be sold in general stores and supermarkets, not just radio and electronics outlets. The "Pixie", shown here, is being sold by 7-Eleven for just HKD 260 (approx €25.60). The receivers support Chinese characters in the Dynamic Label Segment.

The pilot L-band DAB ensemble in Hong Kong was switched off on June 12th 2001, well after the end of the official test period. The two-transmitter SFN was broadcast from Mount Gough and Beacon Hill, providing coverage in Kowloon, the north side of Hong Kong Island and Aberdeen and surrounding area on the south of the island. A lobe to the north of Beacon Hill provided coverage along the Shatin valley.
