Wireless Networking: Introduction to Bluetooth and WiFi
Comprehensive information on Wireless Communication Technologies with focus on Bluetooth and 802.11 WiFi. ‘Wireless Technologies: An introduction to Bluetooth and WiFi’ starts from the ground up for a new user and does a gradual progression into the technical details around wireless communications. There is also a deep dive into two of the most widespread wireless technologies – Bluetooth and 802.11 WiFi. The latest update adds information about Bluetooth Low Energy and Wimax Networks. Introduction A wireless network is a flexible data communications system, which uses wireless media such as radio frequency technology to transmit and receive data over the air, minimizing the need for wired connections. Wireless networks are used to augment rather than replace wired networks and are most commonly used to provide last few stages of connectivity between a mobile user and a wired network. Wireless networks use electromagnetic waves to communicate information from one point to another without relying on any physical connection. Radio waves are often referred to as radio carriers because they simply perform the function of delivering energy to a remote receiver. The data being transmitted is superimposed on the radio carrier so that it can be accurately extracted at the receiving end. Once data is superimposed (modulated) onto the radio carrier, the radio signal occupies more than a single frequency, since the frequency or bit rate of the modulating information adds to the carrier. Bluetooth and WiFi have dramatically altered how people use devices to connect and communicate in everyday life. Bluetooth is a low-power, short-range technology for ad hoc cable replacement; it enables people to wirelessly combine devices wherever they bring them. Conversely, WiFi is a moderate-range, moderate-speed technology based on Ethernet; it allows people to wirelessly access an organizational network throughout a campus location. Although the technologies share the 2.4 GHz band, potentially overlapping applications, and have been pitted against each other in the press, they do not compete and can even been successfully combined for corporate use.

The Nightingale: A Novel
A #1 New York Times bestseller, Wall Street Journal Best Book of the Year, and soon to be a major motion picture, this unforgettable novel of love and strength in the face of war has enthralled a generation. France, 1939 – In the quiet village of Carriveau, Vianne Mauriac says goodbye to her husband, Antoine, as he heads for the Front. She doesn’t believe that the Nazis will invade France … but invade they do, in droves of marching soldiers, in caravans of trucks and tanks, in planes that fill the skies and drop bombs upon the innocent. When a German captain requisitions Vianne’s home, she and her daughter must live with the enemy or lose everything. Without food or money or hope, as danger escalates all around them, she is forced to make one impossible choice after another to keep her family alive. Vianne’s sister, Isabelle, is a rebellious eighteen-year-old girl, searching for purpose with all the reckless passion of youth. While thousands of Parisians march into the unknown terrors of war, she meets Gäetan, a partisan who believes the French can fight the Nazis from within France, and she falls in love as only the young can … completely. But when he betrays her, Isabelle joins the Resistance and never looks back, risking her life time and again to save others. With courage, grace, and powerful insight, bestselling author Kristin Hannah captures the epic panorama of World War II and illuminates an intimate part of history seldom seen: the women’s war. The Nightingale tells the stories of two sisters, separated by years and experience, by ideals, passion and circumstance, each embarking on her own dangerous path toward survival, love, and freedom in German-occupied, war-torn France―a heartbreakingly beautiful novel that celebrates the resilience of the human spirit and the durability of women. It is a novel for everyone, a novel for a lifetime.
