With the rapid development of technology, day by day new innovations are coming to the fore. Wi-Fi certified n devices (which is also known as first WI-FI certified ac products) is one of such innovation presented by technology and it implemented core feature of IEEE 802.11 ac standard.
As said above, networking technology is improving every day and previous versions has been updated in order to provide more benefits to the user. Hence, Wi-Fi association is in the process of presenting a next edition of Wi-Fi certified ac products that offer more features and more efficiency, which you will not get in First Wave Wi-Fi. Since, it is an advanced version of First Wave Wi- Fi, the association named it as Second Wave Wi-Fi; which is also termed as Second Wave 802.11 ac.
As per Wi-Fi association, it will be available in mid-2016 and it works on MU-MIMO technology (Multi-User, Multiple Input Multiple Output). MU-MIMO technology offers the ability to raise the throughput of wireless networks. Wave 1 and other older Wi-Fi routers can only connect a single device at one time and other devices queue up, but using Second Wave Wi-Fi, you will be able to connect multiple devices at a time.
Some of the key benefits of Second Wave Wi-Fi:
- It handles multiple simultaneous Wi- Fi connections through its four antennas
- Available maximum channel width will be doubled in Second Wave Wi-Fi as compared to first wave
- Even it will add support for 80-80 and 160 MHz channels
- Moreover, it will increase the number of transmit and receive streams
- The improvements in the Second Wave Wi-Fi offer the possibility of multiplying the maximum data rates that are currently available in First Wave Wi-Fi.
- Second Wave Wi-Fi is coming with increased throughput and even it allows access points to serve multiple devices
- Wave 2 802.11ac routers added a more-powerful modulation technique so that it will able to deliver maximum physical link rates in the range of 7- to 10Gbps
- It provides up to three spatial streams with maximum physical link rates of 1.3Gbps for each stream
- These devices will also operate on the less-crowded 5GHz frequency band, but they’ll take advantage of several optional elements of the 802.11ac standard.
- These routers creates a single channel with a bandwidth of 160MHz by linking multiple channels of 5GHz frequency band
- Wave 2 802.11ac routers support a maximum of eight spatial streams
