5G will be the major wireless WAN option, and we believe that this transition will be a key driver for SD-WAN adoption. Having at least 10 times faster than 4G with lower latency, and the most advanced encryption technology and authentication features. These advantages of 5G lead itself as a prime choice for wireless SD-WAN use cases.
For the system design, we need to consider at least 6 antenna holes to support WiFi and 3G/4G/5G Networks; especially, the Gen 5th mobile network includes sub-6GHz and mmWave bands.
In recent years, more and more objects will be connected to the cloud through the Internet, forming the so-called “Internet of Things”. Due to the rapid expansion of IoT devices and computing at the edge, billions of IoT devices are in the mesh edge environment and connected to each other; any device may become the weakest link out of security concern. Enterprises now face the challenges of how to effectively manage these end devices, remote deployment, and control security. So, to deal with this challenge, there will be some fundamental changes in the structure and management of the network.
The new standard 802.11ax was named WiFi 6. The birth of Wi-Fi 6 will make wireless high-frequency transmission more efficient; in addition, because Wi-Fi 6 is a regional network, it can coexist with 5G wireless networks.
With the advent of the new Wi-Fi 6 standard, which combines two frequency bands, 2.4GHz, 5GHZ, it also incorporates features such as wide reception range and high network speed, which can meet our needs for high-speed networks at one time.
Due to the characteristics of long-distance Internet of Things, Low Power Wide Area Network (LPWAN) technology has emerged. In the case of only providing batteries, a huge number of devices can continuously transmit a key small amount of data to the monitoring center over a long distance, and under the analysis of Big Data and Artificial Intelligence (AI), the traffic monitoring, real-time updating, emergency processing and other quality optimizing can be achieved. These non-traditional connectivity options will also be a factor for the emerging use of wireless SD-WAN.
