Today,we'll discuss about wireless communication. There are total of 9 wireless protocols,which are listed below: Wi-Fi. Wi-Fi direct.
Well, the answer of the question "Can it replace Arduino" - yes, in many cases it can.
The Arduino Uno WiFi is an Arduino Uno with an integrated WiFi module. The board is based on the ATmega328P with an ESP8266WiFi Module integrated. The ESP8266WiFi Module is a self contained SoC with integrated TCP/IP protocol stack that can give access to your WiFi network (or the device can act as an access point).
Get two XBee modules. Connect one of them to my computer using a USB to Serial Base Unit (SparkFun XBee Explorer USB - WRL-11812 - SparkFun Electronics ) Connect the other to an Arduino using a 'Wireless SD Shield' or 'XBee Shield' (Which should I use?) Use Serial to communicate XBee to XBee.
You can use a USB dongle, which allows the Arduino to wirelessly communicate with any computer or the web. You can use multi-button keyfobs to add very cool remote control capability to your Arduino projects.
The ESP32 is an upgrade of ESP8266 and it has 34 GPIO pins with Xtensa dual-core processor 160MHZ. The ESP32 has a 32-bit processor with an ultra low power co-processor and multiple input/output connectors, which includes digital-to-analog converters. The ESP32 has a secure platform for the Internet of Things.
Wireless networks operate using Radio Frequency (RF) technology, a frequency associated with radio wave propagation within the electromagnetic spectrum. An electromagnetic field is generated when an RF current is supplied to an antenna that can then spread through space.
WiFi uses radio frequency waves to transmit data. Internet is based on predefined TCP/IP protocol to transfer data between various computers. Wireless devices can be connected using WiFi but these devices has access to internet is not necessary. WiFi is not needed for all the computers to be connected on the Internet.
4G is the short name for fourth-generation wireless, the stage of broadband mobile communications that supersedes 3G (third-generation wireless) and is the predecessor of 5G (fifth-generation wireless).
Examples of Wireless DevicesCordless phones are wireless devices, as are TV remote controls, radios, and GPS systems. Other wireless devices include phones, tablets, Bluetooth mice and keyboards, wireless routers, and most devices that don't use wires to transmit information.internet of things wireless modules
