Edimax at the dawn of the n-era

In mid-September this year, the Standards Board of the IEEE (Institute of Electrical and Electronics Engineers) finally adopted the n standard, marking the end of a battle that has been going on for more than half a decade. It was time to.

Everyone can remember that many people saw the future in wireless networks. The solution is also perfect for creating smaller home and workplace networks, as significant cost savings can be achieved by eliminating wiring. During my service years, I myself participated in the construction of many wired networks, and for those who have already done this, I don't need to describe the conditions, the often hard physical work involved in the construction of the network in some buildings. We drilled through one and a half meter concrete columns, crawled through installation tunnels and strung the cables between the floors and under the false ceiling in the office buildings. In addition to the fact that the work was time-consuming during the construction, the workers there were also unable to work properly, and the payment of a large number of working hours burdened the customer's wallet.

When we replaced the old coaxes, there was no question about how I needed UTP, but when I was later asked what I recommend for an office, wired or wireless I always voted first. In the initial period, wireless solutions could not compete with cable networks in terms of speed or security.

The issue of security was largely resolved over time, but there was still the problem of data transfer speed and reliability. In the case of devices with poor transmission performance, it was already a problem if a door that had been open before was closed, and in places where a large amount of data traveled on the network, the speed was insanely slow. For this reason, wired systems remained even in small offices where wireless would have been sufficient otherwise.

With the introduction of the n standard, the use of n or Draft 2.0 tools, we can put the problem of speed forever. I mention the two names separately because the 2.0 standard was born before finalization and essentially included the criteria that were, or are expected to be, or are already included in the final n standard. For this reason, 2.0 devices are automatically rated.

The n standard theoretically means radios with a data transmission bandwidth of up to 630 megabits per second, which communicate with not one but three antennas. A transmission speed of up to 315 megabits/second is available between two antennas. With old devices, the cavalcade of reflected signals was a problem, which confused the systems. On the contrary, n-standard devices use the reflected signals to their advantage, using these reflected signals to increase the range up to four times compared to the ag standard.

With the help of the new procedures, almost all obstacles to the transition to wireless networks have been removed. The reason is almost because of course there are office and company networks that are built in such a way that the wires remain for telephone and gigabit bandwidth, as well as for security reasons. However, it is also possible for these companies to set up smaller wireless subnets. However, in smaller offices and in the home networks that we are more interested in, not only the future but also the present can belong to wireless solutions, as the smooth access and playback of high-definition video materials, TV broadcasts and other multimedia content transmitted over the network can finally become a reality. , which nowadays is an almost unavoidable task for a home network.
