DECT Standard Cipher
Digital enhanced cordless telecommunications (Digital European cordless telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the common standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2. Beyond Europe, it has been adopted by Australia and most countries in Asia and South America. North American adoption was delayed by United States radio-frequency regulations. This forced development of a variation of DECT called DECT 6.0, using a slightly different frequency range, which makes these units incompatible with systems intended for use in other areas, even from the same manufacturer. DECT has almost completely replaced other standards in most countries where it is used, with the exception of North America. DECT was originally intended for fast roaming between networked base stations, and the first DECT product was Net3 wireless LA ...

Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was formed by the Communications Act of 1934 to replace the radio regulation functions of the Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries of North America. The FCC is funded entirely by regulatory fees.

IMT-2020
International Mobile Telecommunications-2020 (IMT-2020 Standard) are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2015 for 5G networks, devices and services. On February 1st, 2021, the standard was published as Recommendation ITU-R M.2150-0 titled ''Detailed specifications of the radio interfaces of IMT-2020'', but most of it was finalized years earlier. For example the requirements for radio access technologies listed below were adopted in November 2017. Following the publication of the requirements the developers of radio access technologies such as 3GPP and ETSI are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies 5G NR, LTE-M and NB-IoT that together are expected to meet all requirements, while ETSI is developing DECT-2020 NR and Nufront is developing EUHT (Enhanced Ultra High Throughput).

Wideband Audio
Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz. In addition, some wideband codecs may use a higher audio bit depth of 16 bits to encode samples, also resulting in much better voice quality. Wideband codecs have a typical sample rate of 16 kHz. For superwideband codecs the typical value is 32 kHz. History In 1987, the International Telecommunication Union (ITU) standardized a version of wideband audio known as G.722. Radi ...

IP-DECT
IP-DECT is a technology used for on-site wireless communications. It uses the DECT air interface for reliable wireless voice and data communication between handsets and base stations and the well established VoIP technology for the corded voice communication between base stations and server functions. The advantage is the circuit switched approach and therefore better specified quality of service for vocal communication than with Wireless LAN. A DECT phone must remain in proximity to its own base (or repeaters thereof), and WLAN devices have a better range given sufficient access points, however voice over WLAN handsets impose significant design and maintenance complexity for large networks to ensure roaming facilities and high quality-of-service. There are some of the traditional telephone equipment manufacturers and smaller enterprises that offer IP-DECT systems, both for residential (single-cell base station/access points), as well as for enterprise usage (multi-cell with multi ...

CAT-iq
Cordless Advanced Technology—internet and quality (CAT-iq) is a technology initiative from the Digital Enhanced Cordless Telecommunications (DECT) Forum, based on ETSI TS 102 527 New Generation DECT (NG-DECT) European standard series. NG-DECT contains backward compatible extensions to basic DECT GAP (Generic access profile) functionality which allow bases and handsets from different vendors to work together with full feature richness expected from SIP terminals and VoIP gateways. CAT-iq defines several profiles for high quality wideband voice services with multiple lines, as well as low bit-rate data applications. Profiles The CAT-iq profiles are split between voice and data service, with the following mandatory features: ; CAT-iq 1.0 "HD Voice" (ETSI TS 102 527-1): Narrow-band (32 kbit/s G.726 ADPCM) and wideband (64 kbit/s G.722 sub-band ADPCM) audio, calling party line and name identification (CLIP, CNAP) ; CAT-iq 2.0 "Multi Line" (ETSI TS 102 527-3): Adds multiple lin ...

Generic Access Profile
The Generic Access Profile (GAP) (ETSI standard EN 300 444) describes a set of mandatory requirements to allow any conforming DECT Fixed Part (base) to interoperate with any conforming DECT Portable Part (handset) to provide basic telephony services when attached to a 3.1 kHz telephone network (as defined by EN 300 176-2). The objective of GAP is to ensure interoperation at the air interface (i.e., the radio connection) and at the level of procedures to establish, maintain and release telephone calls (Call Control). GAP also mandates procedures for registering Portable Parts to a Fixed Part (Mobility Management). A GAP-compliant handset from one manufacturer should work, at the basic level of making calls, with a GAP-compliant base from another manufacturer, although it may be unable to access advanced features of the base station such as phone book synchronization or remote operation of an answering machine. Most consumer-level DECT phones and base stations support the GAP pr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Internet Of Things
The Internet of things (IoT) describes physical objects (or groups of such objects) with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. Internet of things has been considered a misnomer because devices do not need to be connected to the public internet, they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022.

DECT Ultra Low Energy
DECT Ultra Low Energy (DECT ULE) is a wireless communication standard used to design wireless sensor and actuator networks for smart home applications. DECT ULE originated from the DECT and NG-DECT (Cat-iq) technology. DECT ULE devices are used in home automation, home security, and climate control. In May 2013 ETSI released the specification of the ULE standard (Technical Specification TS 102 939-01). The ULE technology is promoted by the ULE Alliance, a non-profit organization, located in Bern, Switzerland. Overview The basic ULE wireless network uses a “star network topology”; i.e. there is one main device, called “base”, which controls the network; the “base” is wirelessly connected to “nodes”, which usually are devices with dedicated functions, such as sensors, remote controls, actuators, smart meters, etc. Some examples of node devices – door locks, smoke detectors, motion detectors, remote controls, gas and electricity meters, baby monitors, elderly car ...
