Slide 10: IoT and Antenna Technology
IoT and Antenna Technology Antennas allow users to gain remote access to their device of choice, eliminating the need for direct wiring between transmitting and receiving devices, giving freedom of location and movement. 10
Slide 11: Antenna Introduction
So, what is Antenna Introduction an antenna? An antenna is a device, or component, that converts guided electromagnetic waves to unguided electromagnetic waves and vice versa. Any metal wire or strip could be used as an antenna. 11
Slide 12: Antenna Introduction
What is an antenna? A single antenna can both Antenna Introduction transmit and receive This is known as the Theory of Reciprocity This is different to audio signals that need 2 devices (speaker and mic) to transmit and receive. Guided electromagnetic waves = waves being passed through the metal w
Slide 13: Antenna Introduction
Antenna Introduction We can categorize antennas in 4 main uses, considering their location on a device Embedded Antennas Outdoor Antennas (inside the customer's device (exposed to weather and harsh and mounted on the PCB) environments) Internal Cabled Antennas External Antennas (inside the customer'

Slide 15: Wireless Decisions…
Wireless Decisions… How much data must be sent? What range is required? What frequencies can be used? How much power is available? Cellular 15
Slide 16: Wireless Protocols
Wireless Protocols Wireless protocols define the standards that allow networking devices to exchange information Cellular Selection is typically driven by range and data usage requirement For remote devices; DATA RATE power usage may be the driving factor cm meters kilometers DISTANCE 16
Slide 17: Wireless Protocols: Range
Wireless Protocols Range Long-range: measured in kilometers e.g., Cellular Cellular Medium-range: measured in tens or hundreds of meters e.g., Wi-Fi Short-range: DATA RATE is generally less than 1 meter e.g., NFC (10cm) Note: Longer distance requires cm meters kilometers lower frequency and mo
Slide 18: Wireless Protocols: Data Rate
Wireless Protocols Data Rate This can be anywhere from a single bit per second (1 bps) to over 1 Gbps Cellular Data rate (channel capacity) is a function of protocol, frequency and power Higher data rates DATA RATE require more power and higher frequency (bandwidth) cm meters kilometers DISTAN
Slide 19: Wireless Protocols: Frequency
Wireless Protocols Frequency Data rate (channel EVERYDAY USES OF THE RADIO capacity) is a function FREQUENCY SPECTRUM of protocol, frequency and power. The higher o WI-FI o BLUETOOTH o MICROWAVES the frequency, GPS o PAGERS o SATELLITE the greater the amount TV o CORDLESS PHONES o WALKIE-TALKIES o
Slide 20: Wireless Protocols: Power
Wireless Protocols Power Power usage is how much power the device is using for 100 W its function and is dependent 10 W on the protocol, frequency, 1W µP DESKTOP range requirement and data 100 mW µP LAPTOP / BICYCLE LIGHTING rates 10 mW GSM Large Higher data rates will require PALM, MP3 recharge
