2. SDP 2011 Team Goeckel PDR MotivationOverviewRequirements Architecture Plan 3 Current digital cable systems Long, clumsy wires Awkward jack placement One receiver box per TV. Other options Windows Media Center Extender AI Tech Wireless Cable ….Not everyone is a tech wiz. Most people prefer to just plug in and play Motivation

3. SDP 2011 Team Goeckel PDR Available Solutions MotivationOverviewRequirements Architecture Plan 3 Need lots of expensive equipment to implement Will take the average person a decent amount of time to set up (hardware and networking) AITech Wireless Cable TV: Limited Functionality Can only broadcast one channel per transmitter Need specialized remote to change channel

4. SDP 2011 Team Goeckel PDR Proposed Solution MotivationOverviewRequirements Architecture Plan 2 Develop a system that would use radio frequencies to transmit cable signal. Create a transmitter able to broadcast multiple channels to different TVs. Create a receiver that will require no external control to receive broadcast. Use a smart phone to control channel being watched on each TV.

6. SDP 2011 Team Goeckel PDR Requirements Specifications MotivationOverviewRequirements Architecture Plan 4 Cost: Under $200 Size: Transmitter box should be 8x6x2 or smaller. Receiver will be small enough to plug right into back of TV. Easy to Control: Omni-directionally transition, easy to use interface Multiplicity: transmit separate channels to up to four different TVs. Security: Password protected user accounts on server, parental control Legality: uses ISM bands Ability: work at distances up to 150 feet.

7. SDP 2011 Team Goeckel PDR MotivationOverviewRequirements Architecture Plan 4 Technical Specifications The demodulated signal will have an acceptable signal to noise ratio and signal strength so that the QAM tuner in the TV can decode the incoming signal Power: The device will be powered by a 12VDC wall outlet power adaptor. Reception at distances up to 150 feet Maximum interference between adjacent channels will not degrade TV image SNR 30dB Impedance 75 Ohm Bandwidth IF 6-800MHz Temp -40C-85C RF Frequencies 2.406-2.430MHz
