There are many trends in our IT industry. Here we are going to discuss about the emerging technology in IT (i.e.) Wi-Fi technology. Wi-Fi (wireless fidelity) is a way to connect to the internet without any wires or cumbersome cables. Wi-Fi technology uses a radio technology called 802.11 b for the wireless connectivity. 802.11 buses 2.4GHz of band frequency spectrum with a bandwidth of 11Mbps(802.11a-5GHz,54Mbps & 802.l1g-2,4GHz,54Mbps).In this paper we have discussed in detail about what Wi-Fi is and How does it work, what the hotspots are and how does the Wi-Fi technology has been implemented in these hotspots. The Wi-Fi technology finds its great utility in the device called Infinity Tele Smart patient-worn technology system, a full size patient monitor system, in the palm TX handheld device and also in many other medical types of equipment. It is also playing a major role in the Robotics. Though there exits many other wireless technologies such Bluetooth, Wi-Fi competes them with its high data transfer rate and the transmission of the data over a large distance. Though Wi-Fi is a very advantageous and a powerful technology, it is also posed to some defects during the transmission of the data. To say like, interference with the household devices like microwaves and it's also possible for hackers to use your access point to connect to the Internet. To overcome the above mentioned discrepancies, we have also discussed about the security measures to be provided for the transmission.

1. WHAT’S WI-FI?
A way to get Internet access, the term Wi-Fi is a play upon the decades-old term Hi-Fi that describes the type of output generated by quality musical hardware, Wi-Fi stands for Wireless Fidelity and is used to define any of the wireless technology in the IEEE 802.11 specification - including (but not necessarily limited to) the wireless protocols 802.lla, 802.llb, and 802.lIg. The Wi-Fi Alliance is the body responsible for promoting the term and its association Vorith various wireless technology standards. When you use Wi-Fi technology, you connect wirelessly to a base station that provides the link to the Internet or other type of network. Remember that today, handhelds and laptops have the same ability as many PC workstations. So, the same handheld device that enables control over a V A V, boiler, chiller etc. will also allow access to asset management software. Thus, maintenance requests and equipment orders can also be done from the field immediately.
Wi-Fi has a lot of advantages. Wireless networks are easy to set up and inexpensive. They're also unobtrusive -- unless you're on the lookout for a place to use your laptop, you may not even notice when you're in a hotspot. In this article, we'll look at the technology that allows information to travel over the air. We'll also review what it takes to create a wireless network in your home.

1.1 WI-FI NETWORK:
The composition of a business and its facilities will dictate the structure of the Wi-Fi network it implements and operates. There are a myriad of options: development of proprietary wireless extensions or utilization of public space nodes. The latter are gateways implemented and maintained by outside organizations and businesses. Interoperable vendor equipment is, put simply, paramount...
