What is WiBRO?

According to abbreviationfinder, WiBRO is a wireless Internet Broadband technology developed by the Korean Telecommunications Industry. It adapts TDD to duplex (separate transmission and reception), OFDMA for multiple access and 8.75 MHz as channel bandwidth.

WiBro was devised to overcome mobile phone speed limitation (for example CDMA 1x, cdma 2x 3x cdaa) and to add mobility to broadband Internet (for example ADSL or wireless LAN. In February 2002, the Korean government allocated 100 MHz of the electromagnetic spectrum in the 2.3-2.4 GHz range, and by the end of 2004 WiBro Phase 1 was standardized by Korea’s TTA, and by the end of 2005 ITU reflected WiBro as IEEE 802.16e Commercial service was launched in June 2006 and the fee is around 35 euros.


The WiBro base stations will offer an aggregate data throughput of 30 to 50 Mbps/s and will cover a radius of 1.5 km. In detail, it will provide mobility for mobile devices up to 120 km/h, compared to wireless LAN whose mobility is the speed of a person in motion and mobile phone which has mobility of up to 250 km/h. During testing at the APEC Summit in [[Busan in late 2005, the actual range and Broadband were a bit lower than these numbers. The technology will also offer service mobility. The inclusion of QoS(Quality of Service) enables WiBro to support video content and other data reliably. All of these may be the strongest advantages over the Wimax standard.

Network deployment

  • SK Telecomand Hanaro Telecom have announced a partnership to expand WiBro nationwide in Korea, except for Seoul and six provincial cities, where independent networks will be rolled out.
  • In November 2004, Intel and LG Electronics executives agreed to ensure compatibility between WiBro and WiMAX technology.
  • In September 2005, Samsung Electronics entered into a deal with Sprint Nextel Corporation to provide equipment for a WiBro trial.
  • In November 2005, KT Corporation (Korea Telecom) demonstrated WiBro trial services during the APEC Asia-Pacific Economic Cooperation Summit in Busan.
  • February 10,2006: Telecom Italia, the dominant telephony and Internet Service Provider in Italy, together with Korea ‘ s Samsung Electronics, demonstrated a WiBro network service to the public during the 2006 Winter Olympics, held in Turin., with a download speed of 10 Mbit/s and an upload speed of a few hundred kbit/s even when moving up to 115 kilometers per hour.
  • In the same event they secured a future of 20-30 Mbit/s by the end of this year (2006) and 100+ Mbit/s down / 1+ Mbit/s up in 2008KT Corporation will launch commercial WiBro service to Mid 2006. KT Corporation and SK Telecommunication launched WiBro around Seoul on June 30,

Device Deployment

In December 2005, Samsung introduced its WiBro SPH-H1000 and SPH-M8000 TDA phones at the 2nd International ComBCon (Broadcast Communication Convergence Conference and Exhibition). WiBro, an acronym for Wireless Broadband, is Korea’s commitment to WiFi communication. It is said to be the Asian equivalent to WiMax technology.. WiBro implements the IEEE 802.16e standard, just like WiMax, but with different objectives: speed and coverage don’t matter here as much as the reliability of the signal even when we’re on the move. In fact WiBro will allow speeds of up to 1 Megabit/s even if we are moving at 60 km/h. Although for this, the coverage will be reduced to less than 1 kilometer around. However, all this has an explanation: Korea, the country in which this technology has been exploited since [2006]], is one of the countries in the world with the most WiFi coverage throughout its territory, so it is of little importance to them the range of the signal (always within a reasonable limit, of course), giving more importance to its being continuous and stable (maintaining a constant bandwidth even if we are walking or in a car).phones, like the Samsung m8000 or possible [[consoles\ like the IRiver.
