However, he declined further comment or to give a specific launch date.

All four WiMAX licence holders will need to launch their services by the end of the month or risk penalty from regulators, including the revocation of their licence. At risk are performance guarantee bonds of reportedly up to RM7.7 million.

Green Packet Bhd's Packet One Networks (M) Sdn Bhd (P1) and REDtone International Bhd launched their respective WiMAX services earlier this week.

P1 launched its services in Kuala Lumpur on Tuesday, followed by REDtone a day later in Kota Kinabalu. Asiaspace DotCom Sdn Bhd on Monday said it would launch its services on Aug 30.

YTL E-Solutions's Bizsurf (M) Sdn Bhd is the fourth WiMAX licensee.

Energy, Water and Communications Minister Datuk Shaziman Abu Mansor highlighted on Tuesday the Aug 31 launch deadline. He said the ministry would revoke licences that are not being put to use and give them to "someone who is serious" in rolling out. The minister also highlighted the year-end deadline for the WiMAX licensees to achieve a minimum 25% population coverage.

All licence holders will also need to cover at least 40% of the population in areas they are licensed in within three years. P1, YTL E-Solutions and Asiaspace can roll out nationwide, while REDtone is confined to Sabah and Sarawak.

P1 chief executive Michael Lai had said it was the company's target to attain a 25% coverage by year-end.

REDtone chief executive Zainal Amanshah on Wednesday said the company would be able to reach the targeted 25% population coverage by year-end by focusing on Kota Kinabalu and Kuching.

In June, YTL E-Solutions entered into a strategic agreement with Xohm, the WiMAX business of Sprint Nextel, for assistance in the rollout of WiMAX services in Malaysia.

YTL E-Solutions executive chairman and managing director Tan Sri Francis Yeoh Sock Ping said working with Xohm would help the company deploy its network faster as well as expedite affordable WiMAX services to both businesses and residential consumers.
