  2. WirelessHART - Wikipedia

    en.wikipedia.org/wiki/WirelessHART

    WirelessHART. WirelessHART within telecommunications and computing, is a wireless sensor networking technology. It is based on the Highway Addressable Remote Transducer Protocol (HART). Developed as a multi-vendor, interoperable wireless standard, WirelessHART was defined for the requirements of process field device networks.

  3. Radioteletype - Wikipedia

    en.wikipedia.org/wiki/Radioteletype

    Radioteletype ( RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. [1] The US Navy Department successfully tested printing ...

    Characteristics. Techniques. v. t. e. Wireless communication (or just wireless, when the context allows) is the transfer of information ( telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.

  5. Wireless local loop - Wikipedia

    en.wikipedia.org/wiki/Wireless_local_loop

    Wireless local loop ( WLL) is the use of a wireless communications link as the " last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access (marketed under the term "broadband") to telecommunications customers. Various types of WLL systems and technologies exist. Other terms for this type of access ...

  6. Radio over fiber - Wikipedia

    en.wikipedia.org/wiki/Radio_over_fiber

    Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
