    摘要: A radial-shaped wireless fence system is provided that contains one or more dogs in a user-defined area without the need for a physical fence or underground wire. The system includes a base unit and at least one collar, and is easy to set up and use. Each of the base unit and the one collar include a temperature compensated crystal oscillator for reducing clock speed variation between the base and collar units, preferably to +/−5 ppm, to effectively eliminate communication errors between the base and collar units.
