This was normally plugged into a separate input/output port on the computer (typically an RS-232 port) and programmed separately from the modem itself. This method of operation worked satisfactorily in the 1960s and early 1970s, when modems were generally used to connect dumb devices like computer terminals (dialling out) with smart mainframe ...
Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16.. MID is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements.
The reverse link (sometimes called a return channel) is the link from a mobile user to a fixed base station. If the link includes a communications relay satellite, the reverse link will consist of both an uplink (mobile station to satellite) and a downlink (satellite to base station) which together constitute a half hop.
Link 16 is a TDMA-based secure, jam-resistant, high-speed digital data link that operates in the radio frequency band 960–1,215 MHz, allocated in line with the International Telecommunication Union (ITU) Radio regulations to the aeronautical radionavigation service and to the radionavigation satellite service.
Link adaptation, comprising adaptive coding and modulation (ACM) and others (such as Power Control), is a term used in wireless communications to denote the matching of the modulation, coding and other signal and protocol parameters to the conditions on the radio link (e.g. the pathloss, the interference due to signals coming from other ...
There are benefits to the full-scale implementation of the two key elements of Link-16: (1) the message "catalog" and (2) the specific radio waveform (i.e., frequency hopped, Lx-band CPSM, spread-spectrum and Reed–Solomon coding, omni-directional broadcast). Link 16 terminals implement the "NI" node-to-node protocols as well as one or more of ...
ATC clearance (ACL), aircraft communication messages (ACM), and check mike (AMC) services are supported, including the automatic uplink of the SSR transponder code into the cockpit. CPDLC will probably be a major enabler for following on projects as monitor message, route clearance uplink, 2-4 D trajectories, continuous descent approaches , and ...
A RIL is a key component of Microsoft's Windows Mobile OS. The RIL enables wireless voice or data applications to communicate with a GSM/GPRS or CDMA2000 1X modem on a Windows Mobile device. The RIL provides the system interface between the CellCore layer within the Windows Mobile OS and the radio protocol stack used by the wireless modem hardware.
