Thailand’s mobile operator, Total Access Communication Public Company (DTAC), has selected Nokia Siemens Networks (NSN) as one of its two vendors to upgrade its network to 3G. Under the terms of the agreement, NSN will deliver radio access network with both 2G and 3G technologies to DTAC. In the Core network, DTAC’s Circuit Switch will be enhanced to accommodate 2G/3G, and a Packet Switch will be introduced for HSPA technology (High Speed Packet Access). This will help DTAC to increase its high speed data throughput in packet core network, simplifying the network architecture and enhancing the data flow between the end-user and the internet.

Total Access Communication Public Company Ltd. (DTAC) has signed a frame agreement with Nokia Siemens Networks as one of its two vendors to upgrade its network to 3G.

“It is just a question of time before 3G becomes mainstream in Thailand,” said Tore Johnsen, CEO, DTAC. “To be suitably prepared for the change, we have chosen two vendors – one of them being our long trusted 2G partner, Nokia Siemens Networks. Having worked with them since 2000, we are certain they will guide us through the high speed data demands that will become the norm for mobile communications in the future.”

“One of the biggest deterrents to 3G has been the associated capital outlay in upgrading current 2G networks,” said Christian Fredrikson, Head of Asia Pacific, Nokia Siemens Networks. ”Our technology provides a cost efficient, smooth and future-proof migration path, enabling operators to embrace the next wave of wireless communications.”

In the frame contract, Nokia Siemens Networks will deliver radio access network with both 2G and 3G technologies to DTAC. In the Core network, DTAC’s Circuit Switch will be enhanced to accommodate 2G/3G, and a Packet Switch will be introduced for high speed packet access (HSPA). This will help DTAC to increase its high speed data throughput in packet core network that simplifies the network and the data flow between the end-user and the Internet*.
