Applications of Infrared Data Association Essay

The conference center has concrete walls that interfere with the RF signals in the large conference room. Bathroom 1 bathroom receives a strong signal but bathroom 2 receives a weak signal due to the concrete wall between the

Radio frequency identification (RFID) can help track patients and record their readings, track equipment, and employee location in the hospital. (Larsen, Marc G. 2012) Radio frequency identification is a technology that captures data using electric or magnetic fields at radio frequencies. Depending on the type of radio frequency identification that is being used an individual can be tracked any where from 10 feet away to 300 feet away, this will allow for both patients and staff to be tracked and or monitored. The three main things radio frequency identification is used for is tracking, monitoring, and identification. This technology can also help improve speed of lab test and monitoring and logging of temperature for refrigerated storage. (McGrady, Elizabeth. 2012)

How? They use a shoebox-sized device called a StingRay. This device (also called an IMSI catcher)

Infrared imaging is also used for military uses. This includes target acquisition, surveillance, night vision, homing and tracking (Infrared). This technology allows missiles and rockets to follow a target by tracking its heat. Night vision goggles and surveillance is used just as with the thermal imaging to detect things that give off heat and show them in a way that allows the human eye to see things that it normally could not.

reach longer ranges. Through gateway devices, it is possible to connect the wearable devices on

Have you ever wanted to see in the heat, well now you can with the infrared camera? The infrared camera is a non-contact device that can detect infrared energy and heat. Infrared can also measure the heat radiation by an object. The infrared camera can show us many things like how much heat something has and the object's temperature. The infrared camera is a much-needed device because the light and the heat can bring us special information that our eyes can't see.

The fig.3 and 4 above is a simulated result showing the red is return loss (S11) and blue is insertion loss (S21) obtained for model. Figure 4 shows the reflection and transmission factor measured for the range 1 GHz to 4GHz. This result gives that the bandpass characteristics are valid for a wide range of EM spectrum for communication. In order to get detailed characteristics in the neighborhood of 2.45 GHz, Figure 4 gives more information needed to the measurement results. With the 3 dB boundary, we get about 260 MHz bandwidth, and insertion loss of -4.3 dB, with parametric dimension as given in Table.1.

Stationary objects – metal boxes, building material, rock walls, fireplaces, etc., that can obstruct, deflect, or block the RF signals.

Solution: Extremely secure channel should be setup between the devices which must have secure shell for the private network. Some NFC enabled devices have capability to listen to the RF signals on the NFC network. When an attacker attacks through a RF device, the differences in RF signals are detected by the NFC transmitter and it stops data transmission (Haselsteine and Breitfuß).

The system operates in the VHF band of 30 to 88 MHz, segmented into 2320 25 kHz channels. SINCGARS radios are also able to operate in a frequency hopping mode, with a rate of 111 hops per second along its 58 MHz bandwidth, and holding all other factors constant, this gives a static OODA loop operational tempo of 9 ms. The typical radio has a worst-case sensitivity of -110 dBm, as given by the manufacturer, with a typical value of -116 to -120 dBm. Adjacent channel isolation is 45 dB, so interference will be ignored in the analysis

Three IR sensors were used for the Redbot and two were used for the final project.

Raydar Electronics was a Manhattan based company and rated among top five makers and integrators of RFID tags and readers in United States.

Since RFID technology use radio waves to transmit data, they are subject to medium as well as other interfering radio waves. One of the core issues RFID

RECEIVER SECTION:- This section is worked as a Flip-flop (Bistable). IC-3 is decade counter, its Pin No.14 is input and Pin No. 2 output. The output of frequency detector stage is used, via a flip-flop, to switch ‘ON’ or switch ‘OFF’ a LED alternately. The receiver uses infrared modules IR-signal from the transmitter is sensed by the sensor through and its output PIN 1 goes low and switched LED. IC-3 is worked on clock pulse which receives to infrared modules at Pin No. 14. Its output at Pin No 2 throughes high.

As a result of less power loss toward unwanted directions, the multipath and interference effects are reduced. Using wideband circularly
