The world's wireless network system was first introduced around the 1990s. Next, the 802.11a protocol was also recognized in 1999. This protocol allows transmission speeds of up to 54 Mbps, using 5 GHz radio waves. Since then, standards for WiFi have been continuously improved. To date, the latest WiFi standard is 802.11ac, which allows data transfer at speeds of about 1.3 Gbps on the 5GHz band and 450 Mbps on the 2.4 GHz band.
What will be the next 3G WiFi standard?
There have been several different development directions to answer this question. Among them, the two main directions are developing the next version of the 802.11 ac standard and launching a new network standard, 802.11ax.
As of mid-2013, the WiFi Alliance officially approved the standard for 802.11ac. However, before that, there were also products produced based on the "draft" version of the 802.11ac standard from 2012. Cisco said that we are currently in the "Wave 1" phase of WiFi 802.11ac. It is expected that "Wave 2" routers will be available in 2015.
These products will use the 5 GHz frequency band (instead of 2.4 GHz as in the current 802.11b/g/n standard) and integrate MU-MIMO (Multi User-Multiple Input/Multiple Output) technology. In addition, it also supports multi-channel aggregation. As a result, 802.11ac devices can achieve maximum data transfer speeds of over 7 Gbps.

After the "Wave 2" phase of the 802.11ac standard will be the advent of a new standard, 802.11ax. The primary goal of this new standard will be to quadruple the network transmission speed to individual devices, rather than just increasing the overall network speed as in previous standards. Huawei (China) recently successfully tested data transmission according to the 802.11ax standard with a speed of 10.53 Gbps on the 5GHz band.
However, don't get too excited, at least for now. Because the WiFi Alliance expects to officially approve this new network standard by 2019. In addition, we may also see products using 802.11ax appear as early as 2016. Of course, these devices will still use the draft standard technology, just like the draft 802.11n and draft 802.11ac.
Good news for smartphone and tablet users, they won't have to wait that long to own a device with the new network standard. Most of the current top products from major players like Samsung, HTC, Sony, and LG already support the 802.11 a/b/g/n/ac standard on both bands, 2.4 GHz and 5 GHz.
If you are looking to own a 3G wifi router, please refer to our genuine products, you certainly won't find any 3G wifi standard devices sold anywhere at a lower price.
