Wireless Communication Technologies Types and Advantages May 29, by Tarun Agarwal 28 Comments Wireless Communication The term wireless refers to the communication or transmission of information over a distance without requiring wires, cables or any other electrical conductors.

Wireless communication is one of the important mediums of transmission of data or information to other devices. The Communication is set and the information is transmitted through the air, without requiring any cables, by using electromagnetic waves like radio frequencies, infrared, satellite, etc.

At the end of the 19th century, the first wireless communication systems were introduced and the technology has significantly been developed over the intervening and subsequent years. Today, the term wireless refers to a variety of devices and technologies ranging from smart phones to laptops, tabs, computers, printers, Bluetooth, etc.

Types of Wireless Communication Technologies In recent days, the wireless communication technology has become an integral part of several types of communication devices as it allows users to communicate even from remote areas. The devices used for wireless communication are cordless telephones, mobiles, GPS units, ZigBee technology, wireless computer parts, and satellite television, etc.

Types of Communication Technologies Satellite Satellite communication is one of the wireless technologies, which is widely spread all over the world allowing users to stay connected virtually anywhere on the Earth.

The Satellites used in this mode of communication, communicate directly with the orbiting satellites via radio signals.

Portable satellite phones and modems have more powerful broadcasting abilities than the cellular devices as they have high range, apart from being more expensive in terms of cost, than their counterparts. For example, for outfitting a ship through satellite communication, a traditional communication system is linked to a single satellite, which allows multiple users to share the same broadcast equipment.

Wireless Networking Wireless Networking technologies connect multiple computers, systems and devices together without requiring wires or cables: Although WiMAX can potentially deliver data rates of more than 30 Megabits per second, yet the providers offer average 0 data rates of 6 Mbps and often deliver less, making the service significantly slower than the hard-wired broadband.

The actual cost of the data available using WiMAX widely varies with the distance from the transmitter. Wireless Networking Wi-Fi Wi-Fi is a form of low-power wireless communication used by many electronic devices such as laptops, systems, smart phones, etc.


In a Wi-Fi setup, a wireless router serves as the communication hub. These networks are extremely limited in range due to low power of transmissions allowing users to connect only within close proximity to a router or signal repeater. Wi-Fi is common in home networking applications which provides portability without any need of cables.

Wi-Fi networks need to be secured with passwords for security purposes in order not to be accessed by others. In a wired network, additional clients require additional wiring. Radio Frequency transmission and wireless networking signals are subjected to a wide variety of interference including the complex propagation effects that are beyond the control of the network administrator.

Security Problems — Wireless networks may choose to utilize some of the various encryption technologies. Range will be insufficient for a larger structure — and, in order to increase its range, repeaters or additional access points have to be purchased.

The speed on most wireless networks will be slower than the slowest common wired networks. Installation of an infrastructure-based wireless network is a complex to set up. Bluetooth Technology Bluetooth technology allows you to connect a variety of different electronic devices wirelessly to a system for the transfer and sharing of data and this is the main function of Bluetooth.

Cell phones are connected to hands-free earpieces, wireless keyboard, mouse and mike to laptops with the help of Bluetooth as it transmits information from one device to other device.

Bluetooth Technology Features Bluetooth technology uses radio waves to communicate between devices. Most of these radio waves have a range of feet. According to the official Bluetooth website, Bluetooth uses a low-power signal with a maximum range of 50 feet with sufficient speed to enable transmission of data.

The pairing process identifies and connects any two devices to each other. It also prevents interference from other non-paired Bluetooth devices in the area. It uses maximum power only when it is required, thus preserving battery life.

What are the Different Types of Encryption Methods?

ZigBee ZigBee is a wireless communication standard designed to address the unique needs of low-power, low-cost wireless sensor, and control networks. ZigBee can be used almost anywhere, as it is easy to implement and requires little power to operate.

Zigbee has been developed looking into the needs of the communication of data with a simple structure like the data from the sensors. Zigbee Technology ZigBee devices are designed for low-power consumption.

Satellites - Types and Uses of Satellites

ZigBee is used in Commercial Applications like sensing and monitoring applications. ZigBee uses very low power and extremely long device battery life. ZigBee gives flexibility to do more with the reliable wireless performance and battery operation.Breccia is a clastic sedimentary rock that is composed of large (over two-millimeter diameter) angular fragments.

The spaces between the large fragments can be filled with a matrix of smaller particles or a mineral cement which binds the rock together. are two types of coordinate systems—geographic and projected. A geographic coordinate system uses a three-dimensional spherical surface to define locations on the earth.

Below are the names of nine different types of satellites. There are also nine pictures of satellites. Each picture is an example of one type of satellite. You can click either on the picture or on the name to learn more about that type of satellite, and its example.

The Spectral Characteristics Viewer helps visualize the different satellite bands of Landsat and other sensors, along with selected spectra and convolving capabilities. Information about the different bands, and which bands to use can be found on this webpage. Start studying Characteristics of the 4 primary tissue types.

Refractors are the most popular telescope for beginners. They use a lens to gather and focus the light of the object it's pointing at.
