Introduction
Wi-Fi is wireless technology in which the data is communicated between two or more Wi-Fi enabled electronic devices using microwaves. In most of the cases the microwaves of 2.4 GHz frequency is used for data communication. Wi-Fi is used to create local area network, or wireless hotspots, or even home area network. Wi-Fi technology is even used in many of the wireless devices such as stereo wireless headphones, or wireless keyboard and mouse other computer peripherals. It has a lot of scope for usage from networking to pairing devices, it provides a wireless connections. There are many other devices, like Smartphone, tablets, Laptops, etc which have Wi-Fi client so that they can access any of the Wi-Fi access point or hotspot to access data services or internet.
Research
Wi-Fi is a known technology and works on the protocols as defined by IEEE (Institute of Electrical and Electronics Engineers) 802.11 standards. The name Wi-Fi is used as a synonym for Wireless LAN or WLAN. Normally the range of any wireless access point is few meters, however as it work on microware, the range reduces with any kind of obstacles such as wall. If used in open area, the range could be extended. There are range extenders as well which are available in market. These range extenders combination of two devices, which is wireless client and wireless router or access point. They receive the signals of one access point and transmit the same thus enhancing the range of network. These extenders work as wireless repeaters.
Technology
Wi-Fi works on microwaves with two widely used bands of 2.5 GHz and 5 GHz. It is based on the standards as per the IEEE 802.11 standards. The technology is used for transmitted data packets wirelessly. Wi-Fi he...

    Domestic Surveillance Citizens feeling protected in their own nation is a crucial factor for the development and advancement of that nation. The United States’ government has been able to provide this service for a small tax and for the most part it is money well spent. Due to events leading up to the terrifying attacks on September 11, 2001 and following these attacks, the Unites States’ government has begun enacting certain laws and regulations that ensure the safety of its citizens. From the Foreign Intelligence Surveillance Act (FISA) of 1978 to the most recent National Security Agency scandal, the government has attempted and for the most part succeeded in keeping domestic safety under control. Making sure that the balance between obtaining enough intelligence to protect the safety of the nation and the preservation of basic human rights is not extremely skewed, Congress has set forth requisites in FISA which aim to balance the conflicting goals of privacy and security; but the timeline preceding this act has been anything but honorable for the United States government.
