Definition Of Wireless TechnologyWi-Fi - Wi-Fi stands for Wireless Fidelity and refers to wireless Internet services that utilize dual band networks. This differentiates Wi-Fi from traditional pager networks and offers the obvious advantage of two-way traffic.

IEEE – This term stands for The Institute of Electrical & Electronics Engineers. This group manages the

standards in which wireless networks are held too, as well as other computer hardware standards. The

IEEE makes sure that hardware made by different manufacturers is interoperable.

WEP – This is type of encryption used to secure wireless networks. Wired Equivalent Privacy was initially designed to

offer wireless networks the same inherent security wired networks have. Although never quite reaching the same

level, WEP is still considered a good level of security.

WAN – WAN, or Wide Area Network, connects more then one site into a single network. An example would be three offices in three

cities all accessing the same Internet to do business.

LAN – LAN stand for Local Area Network. Similar to WAN, this network is confined to a single

physical site. Home networks are considered LANs.

PAN – Personal Area Network is new term used to refer to small network that serves a single user. An example of PAN would be a single PC, printer, and an Internet connection.

MAN- Another new term, MAN stands for Metropolitan Area

Network and this type of network offers coverage to an entire city.

Although cost prohibitive, this useful servise can provide Internet access

large areas.

WPA – Wi-Fi Protect Access is a replacement technology fir WEP

keys. WPA offers dynamic encryption methodology as well as hacker

failsafe options to secure and shut down a network.

SSID - A service Set Identifier attaches itself to all data packets that

travel across a particular network.

WML – Wireless Markup Language was the first language used to send content to wireless devices. WAP devices are now more commonly processing XHTML, and standard

HTML.

TYPE OF WIRELESS TECHNOLOGY

Here are the main types, listed as applications

• Voice Communications• Remote Control • Remote Measurement• Item Tracking• Entertainment• Navigation and Location• Quality Management• Risk Management• Networking• Monitoring• Energy Management• Wireless Power Transfer

Voice Communications- This is where it all started people just talking to each other over radios, each the size of about a hundred cell phones. While it was nice to communicate with an actual person, it was a very slow way to exchange information.

Remote Measurement- This a rapidly growing area of wireless technology that allows things that we’re already measuring to be measured more cheaply, and make measurements that were just too expensiveItem Tracking- You can now track items easily, accurately and cheaply by attaching wireless Radio Frequency IDentification (RFID) tags to them.

Entertainment- Entertainment is one of the types of wireless technology that is going to allow us to have some quite surreal experiences in the years to come.

• Wireless speakers• Wireless headphones• Wireless earbuds• Wireless Microphone• Wireless home theatre• Interactive wireless games

Navigation and Location- Global Positioning Systems are becoming one of the more popular types of wireless technology for navigation and location.

Quality ControlDamage to fragile products – If

you’re a supplier, your reputation depends in the care,

skill and integrity of the company that transports your

products to the customer.

Exposure to excessive temperature – Heat can spoil food items but it’s

easy to record the temperature that the goods are exposed to and send

an alarm via a wireless link.

Exposure to excessive humidity – high humidity may encourage the growth of mould on some types of

fruit, especially if the minimum temperature has also been

exceeded.

The shipping agent – can prove that the goods have been

handled reasonably during transport.

The producer – can prove that the goods have not

been handled reasonably during transport.

Risk Management- Of all the types of wireless technology sensors have the widest range of possible applications.

Networking- Of all the types of wireless technology, wireless networking underpins the others, as each can potentially become part of a wireless network.

Local Area Network (LAN) Personal Area Network (PAN) Wide Area Network (WAN)

Remote Monitoring- This type of wireless technology, remote monitoring, always involves the use of some kind of sensor.

Energy Management

•Maintaining a comfortable environmentIn a working environment, such as a large office, careful management using a closed loop system with distributed wireless sensors, allows you to use energy more efficiently... minimizing waste caused by raising the air temperature excessively, allowing it to become uncomfortably hot, while maintaining adequate ventilation and humidity levels.

• Controlling ProcessesClosely controlling energy-intensive processes, such as some factory production lines, can bring about a significant savings in energy and reduction in costs.

Power Transfer- Here are some examples of types of wireless technology that are used to supply power...

A computer mouse receiving energy wirelessly from a special active mouse pad.

Wireless stereo headphones with internal batteries recharging via a re-charge docking station where they are placed when not in use.

An electric toothbrush wirelessly receiving energy from its docking holder to charge its batteries.

ADVANTAGE OF WIRELESS TECHNOLOGY

Is that it allows you to move around the office without having

to plug in or change setting on your computer.

It’s a quick and easy way to connect computers and share a single internet connection, as

well as add new machines to the network.

Setting up wireless network also easier then you might think and you don’t need a degree in IT to

do it.

The growing trend is that corporations are encouraging workers to telecommute and

stay in field. This gives the freedom to the workers. They can have flexible work hours.

Warehouses can start processing orders, while the sales team is

on the field. This provides faster delivery of goods. The whole supply chain gets the benefits

from this process.

They do not need to reserve office cubicles

for telecommuting workers. Money is

saved from the reduced office equipment costs.

DISADVANTAGES OF WIRELESS TECHNOLOGY

The development in the communication systems and the networking has

given rise to the wireless networks.

The comforts of the wireless networks poses serious security threats.

The risk of data being lost is increasing. And the current

wireless encryption protocols are difficult to handle moreover the common users are not aware of the ways of addressing wireless

security matters.

Interface is highly risky to be used for official private

information. The speed and the viability of the wireless

signals drop as more and more users use the same frequency.

The wireless signals are also attuned by the barriers such as walls, doors and devices itself.

The setup of the wireless technology is difficult

maintain.

Hence it an unstable network.

Wireless signals are prone to disrupt by the

infrared and radio signals.

Have four times more expensive than wired

technology due to their difficult setup.

Needs to transfer confidential data over the network wireless

technology is a serious risk to be used.

The various health problems that wireless can pose are memory loss and even cancer.
