Oceanic Digital -, Jamaica
Oceanic Digital Jamaica (ODJ) is a subsidiary of Oceanic Digital Communications of New York. The company is the third placed player in the Jamaican mobile telecommunications market (4.5% market share), behind Cable and Wireless (31%) and Digicell (64%). In the first quarter of 2006 it was estimated that ODJ had 105,000 subscribers in Jamaica (population 2.8 million). The company operates under the name of MiPhone in Jamaica and launched its first wireless services, 2G, in late 2001.
Lucent Technologies provided the first CDMA 2000 network for the company consisting of 80 cell sites covering the island. It is still the most advanced network on the island, superseding both Digicell and Cable and Wireless for technology.
ODJ is now upgrading its CDMA 2000 network so that it can provide more and higher quality services to its subscribers. The work started in July 2006 and is expected to be completed by the end of 2006. The network upgrade is requiring an estimated investment of US$27m.
The Asian infrastructure provider ZTE was chosen for the contract to upgrade MiPhone’s existing CDMA 2000 network. ZTE USA will supply ALL-IP CDMA 2000 EV-DO and CDMA 2000 1x voice and data network equipment, base station subsystems (BSS), and core network equipment, along with the innovative CDMA 2000-based GoTa (Global Open Trunking Architecture) push-to-talk network, and its CDMA 2000 1x voice and data handsets, GoTa handsets, and EV-DO data cards.
The new ZTE technology will allow MiPhone, the exclusive CDMA operator in Jamaica, to provide new services to its customers with GoTa capabilities and high-performance EV-DO wireless broadband data services. The new network including the trunking services enables subscribers to use new advanced features such as enhanced multimedia (voice, data and video) and email access, video-conferencing and web-browsing via high-speed, broad bandwidth connections.
ZTE are also providing support, training, maintenance and management services for the upgraded network.
GLOBAL OPEN TRUNKING ARCHITECTURE (GOTA)
Trunking communication is usually applied to the professional mobile communications field. Unlike conventional digital trunking systems, the ZTE system makes use of CDMA technology to solve the key problems in delivering trunking services. It allows large numbers of trunking users to share relatively fewer communication resources and dramatically improves the speed of call connection.
The system gives fast access, much improved channel efficiency, enhanced privacy and the flexibility to expand the system as demand grows. ZTE has also launched its own commercial GoTa trunking terminals to promote the commercial use of GoTa trunking system, and will continue to roll out a series of terminal products including vehicle-mounted and professional terminals.
Trunking allows a large group of inlet switches at the same time. Therefore the service provider can provide a lesser number of circuits than might otherwise be required, allowing many users to 'share' a smaller number of connections and achieve capacity savings. As an example, the TETRA radio system uses trunking in conjunction with 2G technology, but the GoTa system is the first to make use of 3G CDMA 2000 technology.
