The A-Z Of Wireless Technology You “Need” To Know

I am certain you may know a little bit what the name ‘Wireless‘ is. In this piece, I have given information about what Wireless Technology is? Also presented types, its functioning and many exciting data to reflect.

It is essential to know how wireless technology works. The devices you occupy like smartphones, speakers, etc and devices you use – wireless headphones/earphones, smartwatches, etc. We own them but we must also apprehend how they run and how it provides the advantages through numerous techniques.

In this piece, I have given –

A]. Definition of Wireless
B]. What is Wireless Technology??
C]. Types Of Wireless Communication Technology
D]. How Wireless Technology Works?

Let’s start the valuable information film now –

What is Wireless Technology??

Definition of Wireless Technology

Wireless Technology [WT] gives you a hand to interact between 2 or more than 2 objects without utilizing wires or other familiar terms ‘cables’ {No need at all}. This method includes communications using radio frequency [RF] as well as infrared waves [IW].

A general term which has a lot of technologies and devices that transmit data over the air.

Who Gave Birth To Wireless Technology?

The World’s first wireless telephone communication was conducted in the year 1880 by Alexander Graham Bell and Charles Sumner Tainter. They both discovered and patented the “photophone“, a telephone that carried audio conversations wirelessly over modulated light beams [these are linear projections than electromagnetic waves].

After then, 2 personalities named Heinrich Hertz and Guglielmo Marcon commenced this development of electromagnetic waves. Developed the first commercial RF communications, the “wireless telegraph” in the late 1890s and so on. It’s very compact and reliable for individuals to use wireless technology, not like wired technology.

On the other hand, wireless technology is towards pricey side than wired technology.

Other major plunges of wireless technology have been in the field of broadcast communications like television, direct broadcast satellite, radio, etc

Types Of Wireless Communication Technology

Covers various types of wireless communication technology

  • Bluetooth
  • Satellite Communication
  • Infrared [IR] Wireless Communication
  • Wi-Fi

A]. Bluetooth

Bluetooth is a very popular established name. The foremost working of the Bluetooth technology is that it grants you the power to connect among various Electronic Devices [ED] wirelessly and also helps you to transfer the data from one medium to another medium.

Did You Know This –

Bluetooth was originally called Short Link Radio Technology until 1997. After 1997, the title was swapped to ‘Bluetooth’.

Example like – Your smartphone can be connected to wireless speakers, wireless earphones/headphones and many more with the advantage of Bluetooth.

Who Invented Bluetooth?

 

Bluetooth

 

 

Jaap Haartsen invented Bluetooth along with working at Ericsson in the 1990s. Amazing to know is – Bluetooth is named after the king of Denmark and Norway – Harald Blatand  {Blantand = Bluetooth}

Limitations of Bluetooth

Everything in this world has positives and has negatives too. Bluetooth negatives include –

A]. Short Range

  • Range up to about 30 feet but it can diminish the range even more if hurdles like walls, ceilings etc occur.

B]. Pairing Process

  • The pairing method can be at times tedious. This entirely depends on what kind of devices are affected.

B]. Satellite Communication

Satellite communication is generally spread throughout the world and because of this, it helps the users to stay connected everywhere on this planet.

Satellite Communication Positives

1]. A user has the power to control the network

2]. Distances are simply covered and the price doesn’t imply

3]. Each and every corner of the earth is covered

4]. Broadcasting possibilities increased

5]. Adaptability

6]. LEO [Low earth orbit] and MEO [Medium earth orbit] satellite types have lower propagation stop and moderate losses compare to GEO [Geostationary earth orbit] satellite. On the converse, this will avail them to be used for global coverage.

Negatives Of Satellite

1]. The satellite has a lifespan and will be in working condition for 12 – 15 years. Within that time frame, another launch has to be planned before that satellite displays un-responsive.

2]. Launch charges and initial prices are way too expensive

3]. Once the satellite is launched, it needs to be observed and checked at frequent intervals so that it can remain in the orbit.

Applications Of Satellite

Satellite communications provide services

1]. Telecommunications
2]. Data communications
3]. Broadcasting

1]. Telecommunications

Telecommunication services include phone calls and services contributed to phone companies. A service which is provided by a telecommunications provider.

2]. Data communications

Data communications refer to the transmission of digital data among more than 2 computers and a computer network is a telecommunications network that permits computers to swap data.

In other words, provides internet applications like browsing/surfing, GPS and several more.

3]. Broadcasting

There are 2 types of broadcasting –

  • Radio broadcasting
  • TV broadcasting

These broadcasting services are directly delivered to the consumers through a medium called DTH {Direct-to-Home} or Satellite Television Services {STS}, Also for advantages for R&D [Research and Development] areas

C]. Infrared [IR] Wireless Communication

IR wireless communication works through IR radiation. What is IR? – IR is electromagnetic energy at a wavelength which is longer than red light. The infrared band of the electromagnet corresponds to 430THz to 300GHz and a wavelength of 980nm.

2 Types of Infrared communication –

1]. Point to Point 
2]. Diffuse Point

Point to Point Communication 

  • It needs a range of view between the transmitter and a receiver. In layman words, there should be direct contact within the transmitter and a receiver which also indicates there should be no barriers between the contact. Remote control is one of the examples.

Diffuse Point

  • Does not need any range of view between the transmitter and a receiver. There is no direct contact even if there are barriers it easily reflects or bounces. WLAN is one of the examples.

Infrared [IR] Wireless Communication Positives

1]. Safety – Radiation used is not toxic to human beings. It is secure and can be used.

2]. Excellent Speed – Wireless has a max speed rate of 100 Mbps. In contrast, IR has a speed rate of 1 Gbps.

3]. Great durability.

4]. Miniature in size and budget friendly too.

5]. Offers high repeatability

Infrared [IR] Wireless Communication Negatives

1]. Cannot reflect or bounce through obstacles like wall, ceiling, dust, smoke, etc.

2]. Infrared waves can hurt your eyes because of high power.

3]. Supports Lower Data Transmission [LDT] related to Wired Data Transmission [WDT]

D]. WI-FI

 

Wireless

 

A low power Wireless Fidelity [WI-FI] which every device has that can be from smartphone to smart gadgets – Alexa! and countless more.

How Wi-Fi Works?

For Wi-Fi to connect with your smart devices, you need a router or your smartphone can act as a Wi-Fi Hotspot. Now this will send wireless signals to your devices. If you consider an example let say in your house – there will be a router which will transmit internet connection wirelessly with the aid of an ISP [Internet Service Provider].

Similarly, your smartphone can act as a Wi-Fi Hotspot. Hence, the phone can share its wireless connection with others.

Wi-Fi needs to be suitably secured for security purposes because others can locate your Wi-Fi without your consent.

How Does Wireless Technology Work??

Wireless technology works like the information which is transmitted from one point to another point. The first point is the transmitter and the other point is the receiver. This is all conducted by a wave called electromagnetic wave

It can send the signals or message by

1]. Sending the right signals through the air

  • Transmitters and receivers sit at the counter end by using an aerial or antenna. It operates like – at the transmitter point, electrical signals leave the antenna to generate the electromagnetic waves which scatter outwards.
  • Likewise, at the receiver edge, the electromagnetic waves produce small electrical signals in the antenna and that is contained up by an electrical circuit
