Additional Physical Format: Online version: Keen, Roland. Wireless direction finding. London, Iliffe & Sons Ltd., Dorset House [pref. ] (OCoLC) Wireless direction finding has a long and distinguished history going back to the very beginnings of wireless communications around the turn of the twentieth century. Many advances have been made in the field of direction finding since the early s, for the most part due to advances in technology rather than new concepts or principles. This is a great book on radio direction finding. It is a bit outdated as I first read it back in , and it was a little outdated then, but still full of great information on RDF techniques and technologies.4/4(22).
Yorkie-Pro™ wireless intrusion detection system (WIDS) is a handheld receiver designed for wireless security audits of data-sensitive government, law enforcement, military and critical infrastructure -Pro sweeps all nearby Cellular, Wi-Fi, Bluetooth and BLE (Bluetooth Low Energy) channels using a high-speed receiver engine in conjunction with a Wi-Fi/BT/BLE . Classical and Modern Direction of Arrival Estimation contains both theory and practice of direction finding by the leading researchers in the field. This unique blend of techniques used in commercial DF systems and state-of-the art super-resolution methods is a valuable source of information for both practicing engineers and researchers/5(3). The Bluetooth specification enhances location services with a direction finding feature that makes it possible to detect the direction of a Bluetooth signal. With Bluetooth direction finding, developers can bring products to market that understand device direction and achieve sub-meter location accuracy. Learn the basics of angle of arrival. signals having a direction of arrival different from that of a desired signal. Multi-polarized arrays can also reject interfering signals having different polarization states from the desired signal, even if the signals have the same direction of arrival. These capabilities can be exploited to improve the capacity of wireless communication Size: KB.
Unless I'm very much mistaken, you can't get the direction - your antenna picks up the signal without a sense of direction. Likewise, you can't get the distance, just the signal strength, which is not the same as distance. Move in front of a wall or put a book in front of the antenna, and your strength will change significantly. Variation in Accuracy of Wireless Fix with Relative Position of Ship and D.F. stations. increase in Accuracy of Wireless Fix due to third D.F.

Typical range varies based upon the device and if optional direction finding antennae are used. Bluetooth devices can be detected from about 50 to feet away. Wi-Fi devices can be detected from about to feet away.
