MDC (Motorola Data Communications), also known as Stat-Alert, MDC-1200 and MDC-600, is a Motorola two-way radio low-speed data system using audio frequency shift keying, (AFSK). MDC-600 uses a 600 baud data rate. MDC-1200 uses a 1,200 baud data rate. Systems employ either one of the two baud rates.
The first versions of LynxOS were written in 1986 in Dallas, Texas, by Mitchell Bunnell and targeted at a custom-built Motorola 68010-based computer. The first platform LynxOS ran on was an Atari 1040ST with cross development done on an Integrated Solutions UNIX machine. In 1988-1989, LynxOS was ported to the Intel 80386 architecture
GSM radio frequency optimization (GSM RF optimisation) is the optimization of GSM radio frequencies. GSM networks consist of different cells and each cell transmit signals to and receive signals from the mobile station, for proper working of base station many parameters are defined before functioning the base station such as the coverage area of a cell depends on different factors including ...
An alarm is a persistent indication of a fault that clears only when the triggering condition has been resolved. A current list of problems occurring on the network component is often kept in the form of an active alarm list such as is defined in RFC 3877, the Alarm MIB. A list of cleared faults is also maintained by most network management ...
The DMS SuperNode Computing Module was first based on the Motorola 68020 Central Processing Unit (CPU) and then upgraded to the Motorola 68030. In the early 1990s it was further upgraded to use the Motorola 88100 and 88110 Reduced Instruction Set Computing (RISC) CPUs. This RISC version of the SuperNode Computing Module was known as the BRISC ...
Motorola Type II refers to the second generation Motorola trunked radio systems that replaced fleets and subfleets with the concept of talkgroups and individual radio IDs. [1] [2] There are no dependencies on fleetmaps, therefore there are no limitations on how many radio IDs can participate on a talkgroup. This allows for greater flexibility ...
The ASTRO 25 network also ensures encryption key assignment over the system's radio channels and enhanced network security tools. [ 5 ] The ASTRO 25 digital radio system is claimed to provide superior audio quality and advanced features which complies with the Federal Communications Commission's 2013 narrowbanding requirements.

In March, 2017, Motorola Solutions acquired Interexport SA. [14] In August 2017, Motorola Solutions announced it completed the acquisition of Kodiak Networks, a privately held provider of broadband push-to-talk (PTT) for commercial customers. [15] [16] Its clients included AT&T, Vodafone, KPN, Verizon, Telefonica, Bell Canada, and Vivo. [15]
