Guyana is bracing itself for the arrival of a new wireless operator in the third quarter of this year when Cel*Star, an affiliate of California-based Trans World Telecom (TWT), launches a new GSM-900 service with capacity for between 30,000 and 40,000 users. Despite concerns from the incumbent – Atlantic Tele-Network-backed GT&T – that the Republic’s mobile market is already close to saturation, Cel*Star and its backer believe there is sufficient scope to attract first time users who have been waiting for the introduction of the type of advanced services offered by GSM. The newcomer hopes to formalise an interconnection agreement with GT&T by mid-March. Cel*Star received its mobile concession in February 2001 and the following year entered into a partnership with TWT with the latter committing investment of USD20 million for network rollout. Siemens and Nortel Networks have been linked with possible equipment contract awards.
