TRENDnet TEW-812DRU Wireless Router: review and testing

The runaway growth in popularity of smartphones has influenced not only on sales of desktop PCs, but also reflected in the other branches of the IT-industry. Seemingly, network technology is the only area where everything takes its normal course on the planned for several years route regardless of external circumstances. But here the developers had to force the events. The fact that all modern mobile gadgets to access the Internet often use Wi-Fi. As a result, the load on the wireless networks was greatly increased and standard IEEE 802.11n is no longer able to cope with it.

TRENDnet TEW-812DRU

Therefore, in early 2014 the following revision IEEE 802.11as was adopted. Let us briefly analyze what benefits it brings to the average user, and what the main differences lay on the previous standard.

Thus, the first of all the channel width was increased from 40 to 80 MHz. In the future it will increase even more up to 160 MHz. This allows double/quadruple the value of IEEE 802.11n. Secondly, the maximum number of space-charge flow is increased from 4 to 8 which also doubles the speed. Thirdly, there was the optimization of methods for data transmitting which will have a positive effect on the speed. Finally, there is a support for technology MU-MIMO.

Its advantages are well represented in this figure. The excessive space-charge flows will not be wasted, and can be used to serve other customers. This innovation will greatly enhance the effectiveness of wireless networks, where a single access point has variety of devices.

Thus, by adding all the factors theoretically it is possible to get data rate of about 5 GB/s. However, in practice you won’t get such results. Despite the transition to the range 5 GHz, space for channels is still not enough, especially if we are talking about 160 megahertz. In addition for 8 space-charge flows a special hardware is required.

So let's make a brief summary of what you can expect from the usage of IEEE 802.11as standard. Based on the characteristics of the equipment so-called first wave (Wave 1), a real data transfer rate will be increased approximately on two-three times in comparison with existing IEEE 802.11n. Of course, this value is not high, but do not forget that the technology is very “raw”. Moreover, its implementation even in this form will give substantial benefits for both domestic and corporate customers. So the purchase of new equipment for networks IEEE 802.11as will look quite reasonable.
