Korea promoted Wibro technology

In Seoul, the HSDPA (High Speed ​​Downlink Packet Access) technology is being considered as the core of 3G mobile networks, and is the foundation for boosting the data transfer rate of wireless networks. HDSPA is optimized to speed up 3-4 times faster than conventional 3G networks today.

Koreans are accustomed to the speed of broadband Internet connection, and they are enjoying the latest technological advances in the field of mobile - high-speed mobile broadband.

Wireless access points

Using WiBro on buses ( Source: hankooki ) Seoul has just begun to deploy WiBro technology (a similar form of Wimax) to promote the wireless broadband wave in this crowded city. Imagine a city covered by "super-powerful" wireless hotspot points, each capable of providing powerful wireless connectivity signals to all city residents in any corner. Come on.

That is the scenario that Korean media, Korea Telecom, will deploy this summer with Wibro technology. Seoul residents will have the impressive capabilities of Wibro: surfing the web, watching football on mobile devices with data transfer rates of up to several Mbps, while still comfortably moving on the children. city.

However, this scenario has not yet become a reality overnight. Currently, Wibro chips are still not built for mobile devices. In addition, technical limitations still exist, the connection signal is still dropped when users move between Wibro base stations, and the Wibro test has only been conducted in 5 districts in Seoul.

Mobile TV

In addition to the wireless broadband connectivity that is gradually becoming available, mobile devices in Korea will have a new function with much better quality, which is mobile TV. In fact, DMB mobile TV technology has been deployed in the country since a year ago, and now has more than one million registered users.

Depending on the type of device that the user phone can catch free terrestrial TV signal or charge satellite TV signal. Obviously, it is no surprise that Koreans are targeting 4G networks. They need to speed up wireless broadband networks even faster!

During a recent mobile device demonstration by Samsung, testers performed data transfers at a rate of 100Mbps while traveling at 60km / h. This ability is more than enough to play video on demand (VOD), live TV and surf the Web simultaneously.
