The Internet of things (IoT), which was considered to be the engine of the future global electronics industry, is now facing a bottleneck.gI8EETC-电子工程专辑

At present, IoT has a wide range of applications, and then a more accurate description is: massive of fragmented application scenarios.gI8EETC-电子工程专辑

And this is the main reason for the current bottleneck in IoT development roadmap.gI8EETC-电子工程专辑

Consistent with this characteristic, the wireless technology that transmitting the physical world (sensors) information, evolving at the same time, both old and new technologies are trying to devour the market share and dominate the future of IoT applications.gI8EETC-电子工程专辑

From close-range, Bluetooth, to mid distance ZigBee, WiFi, and more extensive cellular communications 5G, and different networking architectures, such as NB-IoT, Mesh, LoRa and so on. There are different vendors to provide technologies and chips.gI8EETC-电子工程专辑

So, which or what kinds of wireless technologies will play a leading role in future IoT applications?gI8EETC-电子工程专辑

I will analyze the current status of the mainstream wireless technologies, the possible future development path, and finally give my judgment and suggestion.gI8EETC-电子工程专辑

1. 802.11ac: WiFi compromises with IoT?gI8EETC-电子工程专辑

WiFi is now the most widely used wireless technology for families and consumers, as well as the most popular and familiar among consumers. However, the problems of power consumption, frequency band communication, interference and security make the application of WiFi in the Internet of Things can’t copy the popularity in the consumer products.gI8EETC-电子工程专辑

Now, the new 802.11ac has been optimized to fit the embedded Internet of Things applications.

First of all, what optimizations did 802.11ac do?gI8EETC-电子工程专辑

Technically, 802.11ac works in 5GHz band, with more frequency bands and less interference, with 80 MHz bandwidth, 256 QAM and faster connection speed. Through dynamic channel management, it can effectively improve the network throughput rate and capacity and use standardized beam forming to achieve better performance and wider coverage.gI8EETC-电子工程专辑
