WiFi 802.11ad with up to 7 Gbps – coming soon!

TP-LINK has unveiled at CES 2016 in Las Vegas the world’s first 802.11ad standard router called Talon AD7200. Its capabilities allow to achieve a total rate of up to 7 Gbps. Downloading a feature film in 4K at this speed would take about 4 minutes, and the transfer of thousands of pictures would last only a few seconds. The router will be available on the US market at the beginning of 2016.

Such high speeds are made possible by using three frequency bands. A complete novelty compared to previous Wi-Fi standards is the use of 60 GHz frequency. It allows achieving the speed of up to 4.6 Gbps. It is worth noting that with increase in the frequency the signal attenuation also increases. This means that the range of the router with such high speeds will be limited. The advantage arising from this fact is that the signal interferences in neighboring offices or apartments will be minimized. However, manufacturers have thought about counteracting the negative aspects arising from the rapid decrease in the signal level. The router is equipped with adaptive beamforming which allows to focus the signal on the selected device and the simultaneous elimination of interference coming from other directions.

The other two bands of 2.4 GHz (the maximum transmission speed of 800 Mbps) and 5 GHz (the maximum transmission speed of 1733 Mbps) are well known and have been used in the earlier Wi-Fi standards for many years. This is good news not only in terms of backward compatibility with previously used 802.11 a/b/g/n/ac standards, which will allow it for connection with older devices. Using these bands will allow the router to have a much greater range than in the case of using only one band of 60 GHz. In areas close to the router it will be possible to transmit data using the highest speeds to a laptop or a tablet but moving to another room with the mobile phone in the pocket will not cause loss of connection to the network. It will cause, however, the decrease in speed as it can observed with today’s standard Wi-Fi networks.

At the core of the device are 802.11ad and 802.11ac MU-MIMO solutions from Qualcomm Atheros, Inc., a subsidiary of Qualcomm Incorporated and a dual-core processor clocked at 1.4 GHz. The router has been equipped with two USB 3.0 ports and four Gigabit Ethernet ports allowing fast data transmission (photos, music, videos) throughout the whole network both wirelessly and with the use of cables.

MU-MIMO (Multi-User Multiple Input Multiple Output) allows the use of MIMO, a multi-antenna transmission enabling faster data transmission by multiple users at one time.
