Wireless Technology

Wireless technology allows us to communicate two or more entities or people over distances without using cables or wires.
Wireless technology involves Infrared (IR) waves and Radio Frequency (RF) waves for communication.
Today, the term “wireless” has become a part of our life and without it, we can’t visualize how our lives would be? Let’s understand how does it show up in our lifestyle?

Wireless Technology Revolution

Wireless tech begins with the discovery of electromagnetic waves by Heinrich Hertz (1857–1894).
Marconi was the first person to transmit radio signals to a mobile receiver in the early 1900s.
The revolution of wireless began in the 1900s with digital networking. Communication, social media and other social sharing platforms switch to wireless technology from wired technology.
The Wireless revolution has been raised by the advancement in microwave engineering, radio frequency and shift in the technology from analog to the digital radio frequency due to which voice traffic increased by a very huge amount.
MOSFET (Metal Oxide Semiconductor Field Effect Transistor or MOS transistor ) is the main factor of this revolution.
MOSFET was developed by Mohamed Atalla and Dawon Kahng in 1959. Initially, it was not much more effective as BJT but early by the 1900s, MOSFET had replaced the BJT as the core component in RadioFrequency (RF) (RF) (RF) (RF) (RF) technology.
This is just an introduction to the MOSFET. let’s discuss Why MOSFET is so important for the revolution of wireless technology.

  • LDMOS (Lateral Diffused MOS) is used in Radio Frequency(RF) Power amplification which allows long-distance wireless communication for clients.
  • RF CMOS is used in Radio Transceivers to receive and transmit wireless signals at power consumption with low cost.
  • MOSFET is the fundamental component of modern wireless technology and mobile networks such as 1G, 2G, 3G, 4G and 5G.
  • MOSFET plays an important role in modern wireless technology components such as

✓ Routers
✓ Transmitters
✓ RF power amplifiers
✓ RF Circuit
✓ Radio Transceivers etc.

There was a sudden growth in wireless communication at the end of the 20th century, due to improvement in Digital signal and VLSI (Very Large Scale Integration) RF CMOS.
In recent years, the growth in wireless technology is really remarkable.

Application

Navigation and Location

The global positioning system(GPS) is a space-based Global Navigation Satellite System which provides location and time information and operates under wireless networks.

Remote Control

There are several types of wireless technology remote controllers such as infrared radiation(IR) etc.

Object Tracking

The object can be easily tracked using wireless radio frequency identification (RFID).

Data Communications

Data communication allows wireless networking between different platforms like a desktop computer, laptops, smartphones, tablets and other devices. Data communication technology differ at some points like coverage range, availability and performance.
Examples of data communication technologies are WiFi, Bluetooth, cellular data service, LPWAN, mobile satellite communications and wireless sensor networks.

Medical

Mobile body area network (MBAN) is a new wireless technology which is used to monitor blood pressure, oxygen level, body temperature and heart rate.

Wireless Mobile Phone

It is one of the most important examples of wireless technology as of now. These mobile phones use radiofrequency waves to make phone calls from all around the world.

Energy Transfer

Transfer of electrical energy from the power source to an electrical load without any wires.

Advantages of Wireless Technology

  • Easy to install
  • Prevent the use of cables
  • You can install it anywhere but cables can’t
  • Complete the entrance technology
  • Wireless tech can handle a larger amount of users than the cables connection
  • Users can share their files or any other data with anyone and anywhere without cables.

Disadvantages of Wireless Technology

  • Highly expensive
  • Risk of outsiders accessing your network
  • Coverage range is shorter than the cable connection
  • Many wireless networks can interface with each other
  • Less speed than the wires connection
  • Wireless connection can vary greatly from area to area
