  1. Wireless Microphones

  2. History of Sony Wireless • Sony started in the wireless mic business in 1974 • Sony was first to introduce a PLL synthesized VHF system in 1983 • Sony was first to introduce a direct oscillation type PLL synthesized UHF System in 1989 • Sony was first to introduce a unique SAW filter design for wireless tuners in 1993 • Sony was first to introduce a slot in type tuner in 1995 • Sony was first to introduce a 42 channel simultaneous system with the WD-880 in 1996 • Sony was first to introduce a dual channel portable diversity tuner in 2000 • Sony introduced a rack-mount tuner system with remote IP control in 2002 • Sony introduced cost-effective UWP series UHF diversity wireless systems in 2003 • Sony introduced new UWP Series and WL-800 Series models expanding the line up in 2005

  3. Sony Wireless Microphones • Frequency Selection • ‘A’ suffix model numbers • Include two TV channels • 12 MHz bandwidth • Selection of 94 frequencies • Each with 125KHz bandwidth • Almost all A models are discontinued • ‘B’ suffix model numbers • Include four TV channels • 24 MHz bandwidth • Selection of 188 frequencies • Each with 125KHz bandwidth

  4. Sony Wireless Microphones • WL-800 Series models have four UHF channel blocks • Models designated (30/32) • Contain UHF-TV channels 30, 31, 32 and 33 • Models designated (42/44) • Contain UHF-TV channels 42, 43, 44 and 45 • Models designated (62/64) • Contain UHF TV channels 62, 63, 64 and 65 • Models designated (66/68) • Contain UHF-TV channels 66, 67, 68 and 69 •  Every wireless model needs to have a channel specified

  5. Sony Wireless Microphones • UWP Series models have two UHF channel blocks • Models designated (62/64) • Contain UHF TV channels 62, 63, 64 and 65 • Models designated (66/68) • Contain UHF-TV channels 66, 67, 68 and 69 •  Every wireless model needs to have a channel specified

  6. Wireless Frequency Spectrum Issues • Wireless Mic Spectrum Story: http://mixonline.com/mag/audio_hear_2/ • Background • Today simultaneous analog and digital TV transmission • Crowding the UHF-TV spectrum in major cities • Congress Wireless Act, Bill passed in May 2006 • Actions FCC to implement Ch 2-51 unlicensed low power use • Congress Wireless Act of 2007 (John Cary) • Actions FCC to speed up implementation • FCC UHF Spectrum Reallocation • Ch 52-69 set for Jan 2009 - Some spectrum will be auctioned to the highest bidder • Some will be used for dedicated emergency use (9-11) • Some will be sold to wireless internet service providers • Organizations petitioning the FCC • Politicians are being swayed by big corporations (Intel, Microsoft, Verizon) to move quickly opening ch 2-51 spectrum for unlicensed low-power use to expand high speed internet in rural areas

  7. Wireless Frequency Spectrum Issues • Sony’s Action Plan • Introduce new WL-800 ch30/32 and ch42/44 models • ENG (portable systems) already shipping • Rack Mount Tuner base products will ship May 07 • Offer (charge basis) modification to existing WL-800 Series customers for Sony service to modify selected B-suffix models • Respond to spectrum regulation changes once they are decided • Continue to offer products according to current regulations • Monitoring FCC related activities

  8. Ch 30/32 and Ch 42/44 Support for Existing Customers • Customers who want Sony to modify select ‘B’ suffix WL-800 series wireless (to ch 30/32 or ch 42/44) can have Sony Service perform the required hardware modifications on a charge basis. • Contact Sony Service Teaneck, NJ and refer to UPG-324 Frequency change service program • Phone #: 201-833-5300 • Service Manager: Dominick Esolda
