Cheap at the “eaten” speed

In connection with the measurements, we were most interested in how much the antenna designs know more than those without the antenna, because to know more, we can envelope it. The test was simple. In the panel house that houses the editorial office, we tried to move as far away from the router as possible, while using a software we drew a graph of the current transmission speed. During the measurement, we copied a large file from the portable computer to one that was connected to the router with a UTP cable with a gigabit connection. So this page certainly wasn’t a bottleneck, the graph values ​​could only be affected by the transfer rate between the USB devices and the router. We tried to adjust the rate of departure equally for the three sticks so that the graph showed the extent of the signal strength decrease. The distance traveled was the same in all three cases. The location of the test did not make things easier for Edimax hardware, as the panel strongly weakens the signal due to the amount of iron, and we also introduced the front door of the apartment as a factor. Let's see what result was achieved!

As we have already indicated, we expected the antenna units to perform significantly better, we did not have to be disappointed. The one thing was that we arrived much earlier until the relationship was completely lost, the real trouble was that the journey there was also much shorter. In other words, the single antenna-free interface could only be used at the right speed if we were away from the router for a maximum of one room.

The two antennas performed well, so much so that we noticed that stepping up the stairwell, the signal was amplified as we passed the room on the other side of the wall where the router operated. This can be clearly seen in the upper two curves, where after a decrease in the signal, the transmission rate almost clung back to the original strength. To completely lose the signal, we had to close the apartment door, go through the metal door in the hallway, and walk down a floor in the stairwell. By this time there were many walls and doors between the notebook and the router, and of course there were quite a few meters.

In summary, therefore, in absolutely ideal conditions, all devices performed similarly, but the antenna without an antenna could no longer meet the extreme challenge. For this reason, we can only recommend this device to those who use the machine and the router in the same room, or to those who would prefer to carry it with their machine due to its size. In fact, it takes up less space than the antenna brothers, however, this savings in space is very evident in performance.

We liked the EW-7711Uan the most. Much smaller and lighter than the EW-7711USn, it delivers the same performance. True, the antenna cannot be removed. We can recommend the USn-terminated interface for those who are putting their device to a really difficult task. The antenna can be unscrewed so that even higher power can be connected in place, which can further increase the range.

We didn’t have to be disappointed with Edimax’s tools either. The tested hardware was characterized by a nice external, affordable price for nLite devices and a transfer rate close to the performance of a 100 megabit wired network. Multiple designs are also useless, as everyone can find the right version for them.

Edimax network devices are still used by the domestic distributor, Kelly-Tech Ltd. provided for the test. Thank You!
