History of Sony WirelessHistory 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
Sony Wireless MicrophonesSony 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

• 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
Wireless Frequency Spectrum Issues
Wireless Frequency Spectrum IssuesWireless 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
• 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
