👉 The term "tachytype" is a term used in telecommunications technology to describe a specific type of communication device that operates on low-power, low-cost wireless signals. These devices are often referred to as "wireless modems" or "low-power modems" due to their ability to operate efficiently and cost-effectively compared to traditional wired modems. Tachytypers use radio frequencies (RF) rather than optical fiber for communication, which means that they can transmit data over shorter
