l band การใช้

• MAR was an L band active electronically scanned phased-array radar.
• Digital channels are usually received on an L band QAM stream from a satellite, which uses multiplexing.
• Ofcom auctioned spectrum in L band in 2008 for a number of uses, including terrestrial digital radio.
• AMCA's design prevents detection of the aircraft from L band, C band and X band radars.
• In other parts of the world, satellite radio uses the 1.4 GHz L band allocated for DAB.
• It works on the L band, avoiding rain fade and other issues affecting satellite systems operating at higher frequency bands.
• The centerpiece instrument of the facility is an L band incoherent scatter ( IS ) radar with a fully steerable antenna.
• In May 2012, Squier joined the Li'l Band O'Gold for several shows at the New Orleans Jazzfest.
• The DVB-SH system was designed for frequencies below 3 GHz, supporting UHF band, L Band or S-band.
• On 16 May 2008, Ofcom declared that Qualcomm UK Spectrum Ltd had won the auction of L band frequencies in the UK.
• New York Broadband LLC would order an L band satellite, Silkwave 1, to be fully leased to CMMB Vision of Hong Kong.
• The payload included two L band navigation signals at 1575.42 MHz ( L1 ) and 1227.60 MHz ( L2 ).
• Bangladesh Air Force ordered a Selex RAT-31DL L Band AESA radar from Leonardo-Finmeccanica of Italy worth approximately US $ 19 million.
• It addresses systems where a satellite broadcast directly to mobile and handheld receivers in L band or S band and is complemented by terrestrial transmitters.
• In one configuration, it can carry two 3D X / L band PI SAR ( Parametric Interpherometric Synthetic Aperture Radar ) pods under the forward fuselage.
• Two other IEEE radar bands overlap the ITU UHF band : the L band between 1 and 2 GHz and the S band between 2 and 4 GHz.
• In 2011 RTI CZ obtained a license for Digital Radio DAB ( L Band ) in the Pilsenregion, Carlsbad region, South Bohemian region and inPrague city.
• For example, an object moving at 75 m / s ( 170 mile / hour ) will produce 180 degree phase shift each 1 millisecond at L band.
• Digital Audio Broadcasting, deployed on a very limited scale in Canada in 2005 and largely abandoned, uses UHF frequencies in the L band from 1452 to 1492 MHz.
• It was based on the Chinese DFH-4 satellite bus, and carries a variety of transponders : 4 C band; 14; 8; and 2 L band.
