Thread is an IPv6-based, low-power mesh networking technology for Internet of things (IoT) products. [1] The Thread protocol specification is available at no cost; however, this requires agreement and continued adherence to an end-user license agreement (EULA), which states "Membership in Thread Group is necessary to implement, practice, and ship Thread technology and Thread Group specifications."
Type N connector (female) The N connector (also, type-N connector) is a threaded, weatherproof, medium-size RF connector used to join coaxial cables.It was one of the first connectors capable of carrying microwave-frequency signals, and was invented in the 1940s by Paul Neill of Bell Labs, after whom the connector is named.
3.5 and 2.92 mm (sometimes called K) connectors, which also have a 0.9mm centre pin and cross-mate with SMA and offer higher maximum frequency; 2.4, 1.85 (sometimes called V) externally similar to SMA but have metric threads and a smaller pin, and do not cross-mate with SMA.
The coupling shell has a 5 ⁄ 8 inch 24 tpi UNEF standard thread. [4] The most popular cable plug and corresponding chassis-mount socket carry the old Signal Corps nomenclatures PL-259 (plug) and SO-239 (socket). [12] These are also known as Navy type 49190 and 49194 respectively. [13] A double-ended SO-239 connector is designated as an SO-238.
IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.
The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at microwave frequencies. Invented in the late 1950s and named after Paul Neill of Bell Labs and Carl Concelman of Amphenol , the TNC connector has been employed in a wide range of radio and wired ...
A headache is a pain in the head, neck or face that is often described as a sensation of pressure that varies in location, frequency and severity, according to the National Institutes of Health.
The F connector is an inexpensive, gendered, threaded, compression connector for radio frequency signals. It has good 75 Ω impedance match for frequencies well over 1 GHz [2] and has usable bandwidth up to several GHz. Connectors mate using a 3/8-32UNEF thread. The female connector has a socket for the center conductor and external threads.
