Designed and integrated by the Korean telecom industry as an answer to the drawbacks of speed curbs in the likes of CDMA 1x mobile phones and to increase the flow rate of broadband Internet like the ADSL or Wireless LAN, the technology uses TDD for duplexing, OFDMA for multiple access and 8.75MHz as a channel bandwidth.

As the wibro base stations, provides a dataflow rate of 30 to 50 Mbit/s and also allow the usage of portable internet with in arrange of 1 “ 5 Km, obviously the data flow rate, of devices in motion can be in a range of ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEEE 802.11a in USA and ....etc

WiBro overview

Portable Internet Service (WiBro) is to provide a high data rate
wireless internet access with PSS (Personal Subscriber Station)
under the stationary or mobile environment, anytime and anywhere.

『Portable Internet』was named as 『WiBro』. (End of April, 2004)
WiBro : Wireless Broadband

Much lower service charges than EV-DO
Much higher-speed Internet access than EV-DO
Mobile Internet access in high-speed mobile environment
Much wider coverage than wireless LAN-based services
