1 DT3: RF On/Off Remote Control Technology Rodney Singleton Joe Larsen Luis Garcia Rafael Ocampo Mike Moulton Eric Hatch

2 Agenda Radio Frequency Overview Frequency Selection Signals Methods Modulation Methods

3 Radio Frequency Spans from 3kHz to 300GHz Advantage: Long Distance No stress on line-of-sight Disadvantage: Needs to be operated in accordance with the FCC Interference occurs between RF devices

4 Remote Control using RF Remote Control: Wireless device used to operate audio, video and/or other electronic equipment using transmission. Car opener Garage Door Specifically for our project: Using RF as a remote control to power on/off a system.

5 Selecting a frequency Spectrum Characteristics How rich is your signal Distance and environment Legal Considerations Licensed or unlicensed Allowed power output International regulations

6 Generalizing the RF Spectrum Frequency Examples 3 Hz 30 khz Submarine Communications 30 khz 300 khz RFID, Navigation Signals 300 khz 3 MHz AM Broadcasts 3 MHz 30 MHz Amateur radio, RFID 30 MHz 300 MHz FM Radio, Line of sight aircraft communication, Maritime Radio 300 MHz 3 GHz Broadcast TV, Cell phones, WLAN, Bluetooth, GPS 3 GHz 30 GHz WLAN, Backhaul Communications Lower frequencies will go further and more easily penetrate obstacles Higher frequencies have greater bandwidth

7 Licensed Frequencies If a RF signal is considered Mission Critical a license should be considered Allows for sole use of that frequency Significant cost $19 Billion raised in 700 MHz auction Large Telecommunication providers Other options do exist in the unlicensed spectrum

8 ISM Band Industrial, Scientific, and Medical bands A shared and unlicensed set of frequencies Must accept all interference received Transmission power regulations Usage regulations Regulations vary by country Max power output for 2.4 GHz: US: 30 dbm, before antenna. 36 dbm, with antenna. Europe: 20 dbm 900 MHz is unlicensed only in North and South America Frequency range MHz MHz MHz MHz MHz MHz GHz GHz GHz GHz GHz GHz

9 ISM Congestion 900 MHz and 2.4 GHz ranges are extremely congested Urban areas will have higher congestion

10 RF Detection RF detector monitors the output of an RF circuit and develops a dc output voltage. RF detectors are used primarily to measure and control RF power in wireless systems. In a receiver: Signal strength is a key factor in maintaining reliable communications. In a transmitter: The amount of power transmitted is critical because of regulatory guidelines.

11 Main Applications of RF Detectors Transmitter output power measurement is the primary application. It is essential to know the RF output power. In many cases, the transmitter power is controlled automatically. As a result, the output power is measured and compared to a set point level in a feedback control circuit so power can be adjusted as required.

12 Types of RF Detectors There are two basic types: 1. Logarithmic type 2. RMS type. The log type converts the input RF power into a dc voltage proportional to the log of the input, making the output directly related to decibels. The RMS detector creates a dc output proportional to the RMS value of the signal.

13 General Criteria for Selecting RF Detectors The type of RF signal to be measured is the most important determining factor in the type of detector to use. Log type is best for: general power measurement and control applications pulsed RF signals RMS type is best for: those applications where then signal has a high crest factor or a widely varying crest factor *The crest factor is the ratio of the peak to RMS value of the signal.

14 Binary Coding The process of coding pieces of information and are assigned the values of 0 or 1. Examples of binary coding for: Unique codes for different devices Character strings to bit strings Security

15 Amplitude Shift Key Modulation (ASK) Most basic of shift key modulations. Binary form of AM Type of ASK On/Off Key

16 Advantages v. Disadvantages of ASK WOO-HOO s: Cheaper Conserves power with the case of OOK BOO s: Susceptible to interference

17 What is FSK??? A frequency modulation scheme where digital information is transmitted through discrete frequency changes of a carrier wave. Two types are Minimum-shift keying (MSK) and Audio frequency-shift keying (AFSK).

18 Common Applications of FSK Remote Metering Automatic Meter Reading (AMR) Car door openers/remote car starters. Garage door openers

19 Advantages of FSK Rejects unwanted noise Better signal-to-noise ratio Automatic volume control

20 Expensive Disadvantages of FSK High power consumption Slow data transmission

21 Phase Shift Keying (PSK) A digital implementation of Phase Modulation (PM) Most forms of digital data transmission used a form of Phase Modulation Very high bitrate capabilities Unnecessarily complicated for most remote control applications

22 Analog Signaling (Tone Signals) Information sent using analog tones within the voice band (20 Hz 20 khz) Tones detected or not detected, corresponding to binary 1 or 0 Tones of frequency a corresponds to 1, frequency b corresponds to 0 (AFSK) Can use any analog modulation technique and existing equipment Commonly used by amateur radio and emergency services

23 Conclusion Frequency Selection RF Detection Types of Encoding Types of Modulation Questions?
