There are radio bands considered "unlicensed" that are free to use if your transmitter falls within regulated limits. These are mainly "line-of-sight" bands. Common WiFi and bluetooth radios are examples of standardized packet radios that work in the 2.4GHz unlicensed band.
Licensed amateur radio operators enjoy some advantages the unlicensed devices cannot provide, such as higher power limits and more diverse frequency choices. But these privileges come with restrictions - for example autonomous operation is not permitted in the "shortwave" bands, and operation for any commercial purpose is prohibited.
As Adam mentioned, The APRS standard is a de-facto standard for the format of informational beacons and the method for repeating them across the amateur packet radio network.
From your post I feel that you want "wide-area" service that you can track a roaming device with. Although many areas have existing APRS "digipeaters" setup by local hams, they are all voluntary as the bands can't be used for commercial purposes. As a licensed operator, you could of course setup your own repeaters.
Many types of communications are prohibited on the Amateur Radio bands, but this leaves plenty of room for hobbyist and personal research efforts, and as an Extra class ham I would welcome your project!
您要使用的搜索词是“APRS”——自动数据包报告系统。许多人和公司已经拥有与 HAM APRS 系统配合使用的 GPS 无线电接口，因此您可以通过该 HAM 无线电网络跟踪车辆和其他物体（例如气球）。
The search term you want to use is "APRS" - Automatic packet reporting system. Many people and companies already have GPS to radio interfaces that work with the HAM APRS system so you can track vehicles and other objects (such as balloons) through this HAM radio network.
Amateur radio is not really free - there are obviously no carrier fees, but you need a license to transmit and approved equipment. It's not a free-for-all.

如果您的发射器处于规定限制范围内，则有一些被视为“未经许可”的无线电频段可以免费使用。这些主要是“视线”波段。常见的 WiFi 和蓝牙无线电是在 2.4GHz 免许可频段工作的标准化分组无线电的示例。
不难找到902MHz频段的类似设备，包括标准化的< a href="http://en.wikipedia.org/wiki/ZigBee" rel="nofollow noreferrer">ZigBee 网状无线电设备。
获得许可的业余无线电操作员享有一些未经许可的设备无法提供的优势，例如更高的功率限制等多种频率选择。但这些特权是有限制的——例如，在“短波”频段不允许自主运行，并且禁止出于任何商业目的进行运行。
正如 Adam 提到的，APRS 标准是信息信标格式的事实上的标准，在业余分组无线电网络上重复它们的方法。
从您的帖子中，我觉得您想要可以跟踪漫游设备的“广域”服务。尽管许多地区都有由当地火腿爱好者设置的 APRS “digipeaters”，但它们都是自愿的，因为乐队可以“不得用于商业目的。作为获得许可的运营商，您当然可以设置自己的中继器。
业余无线电频段禁止许多类型的通信，但这为业余爱好者和个人研究工作留下了足够的空间，作为一名特级火腿，我欢迎您的项目！

It is not difficult to find similar devices in the 902MHz band, including standardized ZigBee mesh radio equipment.

GPS 可能有一个串行连接，将位置打印为标准 NMEA 字符串。
有几种通过业余无线电发送 RS-232 Ascii 的协议 - 从此处开始
The gps will probably have a serial connection prinitng out the position as a standard NMEA string.
There are a few protocols for sending RS-232 Ascii over ham radio - start here
业余无线电并不是真正免费的 - 显然没有运营商费用，但您需要传输许可证和批准的设备。这不是一场免费的比赛。
