Description (optional):

Here are the&nbsp;<a href="https://pcbantennas.com/12-kinds-of-wireless-technologies/">12 kinds of wireless technologies</a>. Who will become the main theme of the Internet of Things?
The device is connected to the gateway wirelessly is a typical&nbsp;<a href="https://lcantennas.com/product-category/iot-m2m-antennas/">IoT</a>&nbsp;connection scenario. A gateway is an interface that connects to the Internet through a public broadband cable or DSL modem and then connects to the Internet through an Internet service provider.
In another application scenario called machine-to-machine (<a href="https://ctrfantennasinc.com/applications/iot-and-m2m/">M2M</a>), the device connection will go through a cellular operator, and then to another operator, or directly to the Internet.
Although&nbsp;<a href="https://pcbantennas.com/nb-iot-fpc-antennas/">2G</a>&nbsp;technologies such as&nbsp;<a href="https://pcbantennas.com/gsm-pcb-antennas/">GSM</a>/<a href="https://pcbantennas.com/nb-iot-pcb-antennas/">GPRS</a>/EDGE are very popular, some operators have plans to phase out 2G services.
However, most networks still support&nbsp;<a href="https://pcbantennas.com/3g-fpc-antennas/">3G</a>&nbsp;technologies such as WCDMA and CDMA2000, with data rates up to several megabits per second. Range refers to the distance to the cell site, which can be as long as several kilometers. The cellular connection is obviously an option, but it is more expensive than the other solutions described later.
