Today, your network just got a whole lot closer to 5G

dtac is among the first telecommunications companies in the world to roll out a multi-vendor virtualized core network. Critical to implementing 5G technology, the new technology unlocks fantastic potential for consumers and Thailand 4.0. dtac has successfully completed its first public trial and now runs seven percent of all its data traffic through this new system. The goal is to reach 100 percent by 2018.

Developed in collaboration with Nokia and Huawei, dtac’s virtualized core network is indispensable to the future rollout of 5G. In one test abroad, Huawei achieved a stable speed of 2.8 Gigabits per second, and a latency below 5 milliseconds. Typically, 4G achieves around 14Mbps with 60ms of latency while 4G+ is capable of 40Mbps and 30ms of latency.

A more immediate change to consumers will be dtac’s ability to roll out new services more quickly. The previous generation of systems requires hardware that can only perform a single dedicated task, such as handling voice calls. With almost 20 such functions, changing configurations is costly and time-consuming. Virtualized core networks, though, can run every function on the same hardware.


With virtualized core networks, innovative technologies such as the Internet of Things (which requires a massive number of subscriptions and data consumption from very small to very large) can be deployed very quickly. As dtac forges ahead with its digital transformation, virtualized core networks will be critical to becoming our customers’ favorite digital partner.

Virtualized core networks are also much more affordable than previous systems. This means customers, whose data usage is constantly increasing, can expect costs to remain reasonable.


Regarding virtualized core networks, Prathet Tankuranun, Chief Technology Officer, said, “It was a leap of faith that started last year when we took to jumpstart the virtualization journey of our telco platform, even when the market was still a bit immature. Today makes an important milestone towards the success of our initiative.”

The project is particularly daunting because it spans several vendors–Huawei and Nokia–and is in collaboration with other business units Telenor has invested in. The use of two vendors allows for the system to be more open, but also makes the project that much more complex.

Sebastien Laurent, Country Director of Nokia Thailand, said “We are honoured to enable dtac core network digitalization by on-boarding Nokia, and 3rd party Virtual Network Functions onto dtac’s new Cloud core infrastructure powered by Nokia’s AirFrame servers, CloudBand cloud management and orchestration software as well as Nuage Software Defined Network controller

Lv Yuedong, Director of dtac Account (Huawei Thailand), said, “Core clouds are critical to dtac’s digital transformation. This is a great achievement and an important milestone.”

Rakesh Jain, SVP and Head of Network Asia, Telenor Asia, said “Congratulations to the dtac team for a successful launch. This is a key strategic project across Asia to enable digitalization of the core.  It is really inspiring to see the global way of work in which all business units in Asia have come forward to design and implement this together in a short span of time,”
