有一个例外,就是如果在北美,包括美国和加拿大,使用Garmin Rino是免执照的(新的520,530是5w发射功率)。
看了下garmin的网站,说:
We are pleased to announce that the FCC has granted Garmin a waiver that allows the Rino series units to send position data on GMRS channels. In addition, Industry Canada has established a license-free GMRS service. Canadian Rino units now allow users access to GMRS channels. Position sending/polling is also allowed on Canadian GMRS channels.
又说:
* Using GMRS requires FCC license in the United States. No license is required in Canada.
**Location sending/receiving is available on both FRS and GMRS channels in the US and Canada. The minimum time between updates is 30 seconds (as specified by FCC), except when responding to a polling request
似乎这个允许5W发射的,只是30秒发送一次的GPS位置信号。而不是语音的对讲机信号。 |
