In our times, wireless communication has become a fundamental part of most of our communication devices. These types of technologies include cordless telephones, mobiles, wireless computer parts, GPS units, satellite TVs etc, all of which allow us to communicate in the furthest of areas.
Let’s talk a bit about each of these wireless technologies
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 technologies connect multiple computers, systems and devices together without requiring wires or cables: a wireless local area network or WLAN comes under Wi-Fi.
There are wireless broadband systems that offer fast Web surfing without being getting connected through cable or DSL (Example of wireless broadband is WiMAX). 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. WiMAX is also one of the versions of 4G wireless available in phones as Sprint’s 4G technology.
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.
The pros and cons of Wireless Networking (Wi-Fi)
- Ease of Integration and Convenience – The wireless nature of such networks allows users to access network resources from nearly any convenient location.
- Mobility – With the emergence of public wireless networks, users can access the internet even outside their normal working environment.
- Expandability – Wireless networks are capable of serving a suddenly-increased number of clients with the existing equipment. In a wired network, additional clients require additional wiring.
- Wireless LANs may not be desirable for a number of reasons.
- 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 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 has many functions, and it is used most commonly in wireless communications’ market.
