Autotel (also called PALM, or Public Autom … Autotel (also called PALM, or Public Automated Land Mobile) is a radiotelephone service which was the "missing link" between earlier MTS/IMTS and later cellular telephone services. It used digital signaling for supervisory messages (call setup, ringing, channel assignment, etc.), except the voice channel was analog (as was the original NMT and AMPS cellular systems). This system was not cellular, as it used existent high-power (35 watt) VHF channels. This system was developed for rural British Columbia, Canada, where building a network of low-power cellular terminals to cover a forest would have been prohibitively expensive.t would have been prohibitively expensive.

PALM usó señal digital para todas las operaciones menos para el canal de voz (como el AMPS). Este sistema no fue celular, ya que usó el VHF. Este sistema fue desarrollado para la Colombia Británica Rural y Canadá donde construir una red de terminales celulares de baja potencia hubiera sido prohibitivamente caro.
