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

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc

A Diesel Particulate Filter, sometimes called a DPF, is device designed to remove Diesel Particulate Matter or soot from the exhaust gas of a Diesel engine, most of which are rated at 85% efficiency, but often attaining efficiencies of over 90%. A Diesel-powered vehicle with a filter installed will emit no visible smoke from its exhaust pipe.

In addition to collecting the particulate, a method must be designed to get rid of it. Some filters are single use (disposable), while others are designed to burn off the accumulated particulate, either ....etc

In this paper, the implementation of a shunt active power filter with a small series reactor for a three-phase system is presented. The system consists of multiple non-linear loads, which are a combination of harmonic current sources and harmonic voltage sources, with significant unbalanced components.The filter consists of a three-phase current-controlled voltage source inverter (CC-VSI) with a filter inductance at the ac output and a dc-bus capacitor. The CC-VSI is operated to directly control the ac grid current to be sinuso ....etc

Introduction To Ham Radio Circuit Audio Filter

One of the earliest mode of radio communications is the use of Morse Code on a continuous wave carrier(CW) which is interrupted to generate a DIT and DAH in forming an alphabet. Though it looks simple, this method is often make less reliable as the surrounding man-made noise and atmospheric noise caused interference to the receiver station. This project will help to filter out the interference signal and ensure that the signal received from the Morse code station stand out.

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
