Total Access Communication (DTAC) vows to be at the forefront of the 3G mobile broadband market this year thanks to its upgraded network platform.
The country's second-largest mobile operator expects to almost triple its 3G mobile subscribers from 3.5 million to 10 million this year, using its 850- and 2100-megahertz frequencies.
Prathet Tankuranun, senior vice-president for network operations of DTAC, said the company could install 300 3G base stations per week thanks to its existing 3G-ready network implemented two years ago.
"DTAC is the only operator with an entire modern 2G network on 1800-MHz, and 3G networks on 850- and 2100-MHz frequencies," said Mr Prathet.
DTAC upgraded its 2G network nationwide with internet packet radio access, boosting its data transfer capacity to 1 Gbps from 2 Mbps. This enables DTAC to quickly install additional 3G bases, he added.
DTAC has 50 MHz of spectrum bandwidth: 25 MHz on the 1800-MHz spectrum providing 2G service under CAT's concession, which is due to expire in 2018; 10 MHz on the 850-MHz spectrum providing 3G service with HSPA technology; and 15 MHz on the 2100-MHz spectrum on which it won a licence last October.
Mr Prathet said DTAC is ready to launch its 2100-MHz 3G service by June.
DTAC has 15,700 base stations nationwide. Of the total, 10,500 bases are for 2G and 5,200 are for 3G service on the 850-MHz band.
The company had a public speed test at its transmission centre at Rangsit Klong 5 Road yesterday, following media reports that DTAC slowed its 3G network expansion. The test showed DTAC had a maximum download speed of 29 Mbps and an upload speed of 3 Mbps.
DTAC has 25 million subscribers, 22.5 million of which are pre-paid users.
By comparison, mobile leader AIS has 34 million subscribers and third-ranked True Move has 20 million.
