常用的近距离无线传输有很多种方式：

1）CC1100/NRF905 433MHz 无线收发模块；

2）NRF2401 2.4GHz 无线收发模块；

3）蓝牙模块；

4）Zigbee 系列无线模块；

以上1/2/3模块，一个大概要几十块钱，一套加起来要一百多块，4就更贵了，单个就要上百块钱 而常用的315M遥控模块就便宜很多了，收发一套淘宝上才卖8块钱。这种模块用途极其广泛，例如遥控开关/汽车/门禁/防盗等，大部分是配合2262/2272编解码芯片实现开关的功能。如果能够利用315M 模块实现数据传输，透明传输串口数据，那将是无线数据传输最廉价的方式。

-Commonly used short-range wireless transmission there are many ways:

1) CC1100/NRF905 433MHz wireless transceiver module

2) NRF2401 2.4GHz wireless transceiver module

3) Bluetooth module

4) Zigbee wireless module family

1/2/3 above modules, a probably hundreds of dollars, add up to a hundred pieces, 4 more expensive, single-

One hundred dollars and must 315M remote control module used a lot cheaper, send and receive a set of Taobao and sold 8

Money. This module uses a very wide range, such as remote control switch/car/access control/security, etc., mostly with

2262/2272 codec chip switches. If you can use 315M module for data transmission

Transmission, transparent serial data transmission, wireless data transmission that would be the cheapest way.
