Introduction to Wi. Bro Technology • Wi. Bro, or Wireless Broadband, is the newest variety of mobile wireless broadband access. • Wi. Bro technology is being developed by the Korean Telecoms industry. It is based on the IEEE 802. 16 e (Mobile Wi. Max) international standard.

History • • • Korean based fixed-line operators KT, SK Telecom were the first to get the licenses by the South Korean government to provide Wi. Bro Commercially. Samsung had a demonstration on Wi. Bro Mobile Phones and Systems at the “APEC IT Exhibition 2006”. Wi. Bro is comprised of two phases namely Wi. Bro Phase I and Wi. Bro Phase II

Why Wi. Bro? • Provide the way to use high speed internet service not only in home but also in outdoor. • Maximize the spectral efficiency • Extend the service coverage • Reduce the cost per bit • Low power consumption at AT • Faster handoff

Wi. Bro vs Wi. Max • Physical Layer Differences. • MAC Layer Differences-handoffs. • Network architecture Differences.

Advantages • Low cost and High Data rate. • The technology will also offer Quality of Service. • • • The spectrum it uses is licensed and correspondingly protected from un-licensed use. Wi. Bro can be considered as “Mobile Wi. Max” which can be used while the receiver is in motion. High network capacity

Disadvantages • • The proprietary nature of Wi. Bro and its use of licensed spectrum that may not be available across the globe may keep it from becoming an international standard. Interference.

Future Plans • • Wi. Bro Expected to be widely deployed all over the world in a few years. Some Telcos in many countries are trying to commercialize Wi. Bro.
