Common short-range wireless communication methods include UWB, Wi-Fi, ZigBee and BluetoothIn addition, there are some technologies that have not been widely used and recognized, such as infrared, visible light communication, Internet of Vehicles, Internet of Things, etc.

Which of the following media is used for short-range communication?

infrared For very short-range communications. They cannot penetrate obstacles. This prevents interference between systems.

Which can be used for short-range communication example handhelds?

1) Bluetooth Fills a niche for extremely short-range communication between mobile phones, PDAs, laptops, and other personal or peripheral devices. For example, Bluetooth can be used to connect a phone to a headset or a laptop to a keyboard.

What is short-range wireless communication?

answer: Zigbee It is a wireless communication technology for short-range, low-power digital radio communication. Compared to WiFi and Bluetooth, Zigbee uses very little power and low data transfer rates. …which leads to wireless mesh networks that can cover large areas.

Is it short-range radio communication?

Why is the distance of bluetooth short?

Bluetooth uses spread spectrum frequency hopping technology.This means that it uses multiple frequencies in Limit interference when using multiple devices simultaneously. While Bluetooth does not require direct line of sight, the signal does not travel very far and the device needs to be within about 10 meters.

What is the name of the short-range radio frequency technology?

today SRD or « Short range (radio) equipment » is commonly used. These devices use low power radio frequency (radio frequency) in specified radio frequency bands.

What is the range of Wi-Fi communication?
