SK Sheds Light on Het Net
8:15 AM -- Following SK Telecom (Nasdaq: SKM)'s intriguing recent announcement about its new technology that makes a 100Mbit/s Heterogeneous Network (Het Net) possible, the operator has supplied some additional comments that explain a bit more about its motivation for this development. (See SK Heralds 100Mbit/s Het Net , SK Telecom Integrates Wireless Techs and Get Hip to the HetNet.)
For a refresher, the operator has developed technology -- dubbed the Heterogeneous Network Integration Solution -- that allows simultaneous use of 3G and Wi-Fi, or LTE and Wi-Fi, frequencies to create services with speeds up to 100 Mbit/s.
There is more detail in a Q&A with SK here on Gazettabyte.
But here's what SK Telecom's Bryan Kim, manager at the operator's core network lab, provided in answer to our questions:
How does the technology work?
Why does SK Telecom need the Het Net Integration Solution?
We hope to find out more about the technology at Mobile World Congress in Barcelona next month, where SK Telecom will have the Het Net solution on show.

But here's what SK Telecom's Bryan Kim, manager at the operator's core network lab, provided in answer to our questions:
How does the technology work?
- When using Heterogeneous Network Integration Solution, a handset uses two radio frequencies at the same time. We've built a specialized system installed in core network for simultaneous transmission. Considering theoretical maximum speeds of LTE (75Mbps) and IEEE 802.11 (Wi-Fi, 54Mbps), Heterogeneous Network Integration Solution will offer a theoretical maximum speed of 100Mbps ultra-high speed wireless Internet service.
- Mobile operators know its wireless network environment the best. To realize simultaneous transmission service, it is necessary to analyze quality of multi-networks, and mobile operators can do better than equipment suppliers on this. Also, since mobile operators are competitively offering differentiated services, we wanted to have ownership on the technology and take the leadership by developing it [on] our own, instead of depending on the existing vendors.
Why does SK Telecom need the Het Net Integration Solution?
- With the popularity of smartphones, customers already have handsets that can access to multi-networks, and mobile operators are deploying multi-networks such as 3G, 4G and Wi-Fi. However, mobile operators are providing only one wireless network service and yet put a lot of efforts to manage mobile traffics. We believed that this technology is necessary to enhance the service quality for customers and maximize operators' network utilization through using the already owned multi-networks simultaneously.
