WiBro SANDEEP P J S7 IT Roll NO:17 Contents Introduction History Why WiBro? Technical Overview Applications WiBro vs WiMax Comparison Advantages Disadvantages Future Plans References Introduction to WiBro Technology • WiBro, or Wireless Broadband, is the newest variety of mobile wireless broadband access. • WiBro technology is being developed by the Korean Telecoms industry. It is based on the IEEE 802.16e (Mobile WiMax) 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 WiBro Commercially. Samsung had a demonstration on WiBro Mobile Phones and Systems at the “APEC IT Exhibition 2006”. WiBro is comprised of two phases namely WiBro Phase I and WiBro Phase II Why WiBro? • 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 Technical Overview Public IP Network Operator’s IP Network ACR : Access Control Router ACR RAS : Radio Access Station ACR PSS : Personal Subscriber Station RAS PSS RAS PSS RAS RAS PSS PSS Applications Entertainment • Broadcasting • 3D Network Game • Multimedia Messaging Information • Web Browsing • File Downloading • Interactive News & Info. • Distance Edu./Med. • Home Networking Commerce & Finance Home Networking • Mobile Banking, Trading • Finance, Field Agent Service Comparison with Other Systems Item WiBro High Speed DSL WLAN Cellular(2/2.5G) Service Area Outdoor/Indoor Indoor Indoor (Hotspot) Outdoor/Indoor Data Rate High speed Ultra high speed Very high speed Med/Low speed Mobility High No Low Very high Contents Wired/Wireless Contents Wired Contents Wired/Wireless Contents Wireless Contents Tariff Relatively Low Relatively Low Low High Termina l Smart phone, PDA, Notebook etc. Desktop, Notebook PDA, Notebook Cellular phone, PDA WiBro vs WiMax • 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. WiBro can be considered as “Mobile WiMax” which can be used while the receiver is in motion. High network capacity Disadvantages • The proprietary nature of WiBro 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 • • WiBro Expected to be widely deployed all over the world in a few years. Some Telcos in many countries are trying to commercialize WiBro.
