Times when the only wireless gadgets in the apartment were smartphones, long gone. Laptop, tablet, smart TV, game console - this is the minimum program of today's user, not counting all hours and fitness bracelets. How do you make dozens of devices happy with the Internet? A system of professional access points, for example Edimax Pro, will help. This will cope with the country house, and the work of the large office will order.
Professional approach: how to replace an ordinary router and how to make Wi-Fi seamless

1.

The challenges of progress

Professional technology has long ceased to be a niche. Steep DSLRs once met only in the hands of specialists, and today have become a familiar tool for everyone. And the first computers were created not for games and office, but have long been perceived as something ordinary. Globalization was also avoided by network equipment. What's the difference what is written on the package? The main thing is that Wi-Fi does not brake, and the smartphone and laptop are always online.

Moreover, today, air conditioners, heating boilers, security systems, refrigerators and so on are connected to the global web. To such an influx of customers, no consumer router is ready. Like its owner: constant speed drawdowns due to congestion of wireless network optimism will not add to anyone.

There are many situations in which a familiar router cannot cope with tasks. The rather large area of ​​the premises, the obstacles in the form of thick concrete walls and partitions, a large number of neighboring devices - all this does not in the best way affect the quality of the connection. You can’t connect a phone or a tablet to the Internet via the wire, and the sockets plugged with repeaters are a dubious way out. Indeed, as the signal is removed from the original source, the speed and stability of the connection drops significantly.

Do not always help out and several separate routers: switching between wireless networks is not instantaneous. Moreover, two routers are two stand-alone devices that can not communicate with each other and distribute clients. They only interfere with each other in the radio channel, creating noise and interference in the home air. Even if two gizmos with antennas distribute a network with the same name, it is not a single one. As a result, video calls will be cut off, and videos on YouTube will slow down. Especially if you get to the "dead zone" border switching between routers.

To solve the problems described above will help professional network equipment, but it is not about some complex server systems. Setting up seamless Wi-Fi for an office or a country house is a little more difficult than organizing wireless Internet in a regular apartment. And although such equipment was created with an eye on business problems, today it also helps the average users hung with gadgets.

5.

Professional approach

The costs of professional equipment can easily be justified by the benefits of daily use. The advantage of such systems, including products Edimax Pro , is the creation of continuous coverage with a single SSID (the name of your Wi-Fi network) throughout the territory. Whether it's a house, an office, an apartment or even a cottage site. The result is a unified infrastructure without drawdowns in terms of speed and signal strength. Such a network is called "seamless with support for Wi-Fi roaming". That is, with instant switching of moving clients between points, as it happens with a mobile phone when moving between carrier base stations.

6.

It is not difficult to construct such a system independently. This will require:

  • Router. He will take the Internet from the provider or mobile operator and distribute the home network. The old household router will do, too, but it will have to be disconnected from the Wi-Fi so that it does not interfere with the "older" ones.
  • Access points supporting IEEE802.11r and IEEE802.11k standards - they are responsible for seamless client switching - will become Wi-Fi sources throughout the house. The number of devices that will be required for complete coverage depends on the area of ​​the room and the thickness of the walls.
  • RoE-switch, or, as it is also called, switch. Through it, all points will be connected to a single system and immediately receive power. Of course, it is possible to power the equipment from the supplied power supply units (then a RoE-switch is not needed). But, since you still need to lay a LAN cable for high-speed Internet, it is more logical to combine this process with PoE-powered technology and not to produce extra wires.

Unlike household repeaters, a professional system often implies that a Gigabit Ethernet cable always comes to every point from the router. This guarantees the highest speed without losses on all sections of the network. In the center of the connection scheme is a router and a switch. A wireless connection is also possible, however, the noticeable loss of speed is not worth saving time for laying wires.

7.

All the resulting infrastructure is centrally managed - it's enough to make one of the access points by the wireless network controller. The user will only need to adjust the main point, and with the other "subordinates" the controller will sort out automatically.

The 802.11k standard, which is responsible for roaming Wi-Fi, helps implement switching devices on the fly. With it, several access points exchange data and indicate to the client where to connect. The protocol transmits information about all access points and the status of the network into which they belong. Before you start moving, the gadget will already "know" where exactly the qualitative connection will take place.

The 802.11r standard, in turn, provides a seamless transition between access points. Once you establish a connection, the Fast Basic Service Set Transition technology will take the client's authentication to itself on a network-wide scale. The procedure takes no more than 50 milliseconds - the change of the transmitter occurs unnoticed. Video communication using such a scheme will not be interrupted even during a quick run through the office or multi-storey building, and the 4K-roller on YouTube will not hang. The user will not even notice that he switched to another signal source.

An important condition for the correct operation of a seamless network is the support of the mentioned communication standards as access points, there and client devices. They will function in the network in any case, however, the smooth transition between the sources of the signal will have to be forgotten. Fortunately, most modern gadgets already support both standards, but it is better to look in the specification in advance.

8. Share and Download

A drop in power or loss of a wireless signal when moving away from a router is a problem familiar to many. And if the "friendly" software at the same time dropped the download of an important file or interrupted a responsible video call, it is unpleasant doubly. Especially if this happens with enviable regularity, interfering with the work.

Of course, a typical dual-band router supports simultaneous operation at 2.4 and 5 GHz. In the first case, the coverage radius is increased and backward compatibility with old devices is maintained, in the second - the data transfer speed is significantly increased. The trouble is that you can only connect to one of the bands - each device remains tied to its frequency.

9.

But the Band Steering technology used in professional equipment allows two networks to give one name. And automatically selects the optimal frequency for each gadget in the signal range. If the phone starts to “fall off” from high-speed Wi-Fi, it will automatically be transferred to a more long-range 2.4 GHz band, albeit at the cost of speed loss. With a consumer router, you can not turn this trick. Even if several networks are configured on it, the client will cling to the first in the list until the last until the signal disappears completely.

Conversely, if there are many dual-band devices in the 2.4 GHz band, then, thanks to the same band-styling, Edimax Pro will transfer some to the neighboring frequency. It will happen automatically, without any user involvement or disconnection.

11. Practical Wi-Fi Magic

On the convenience of switching between signal sources, the advantages of network equipment with the Pro prefix do not end. When the number of customers is in the tens, you have to deal not only with signal quality, but also with load distribution. And here the potential of professional technology is much higher than that of the consumer.

It is enough to launch a proprietary application to adjust the signal strength of any device or set uniform Wi-Fi parameters. For the convenience of identifying multiple users, the equipment is equipped with its own RADIUS server. It allows you not only to store customer data, but also to remember their access rights. At the same time, you can create up to 32 SSIDs (16 for each frequency range) in order to once and for all deal with the priority of speed and the privileges of “your own” and “alien”.

Differences from domestic routers lie not only in hardware stuffing and settings, but also in the way of placement. Ceiling mount Edimax Pro CAP1200 eliminates interference and unload sockets. Using Power over Ethernet (PoE) technology, power is supplied over a regular LAN cable.

12.

Like an advanced router, a professional access point allows you to create several networks at the same time, but its capabilities are not limited to this. For example, for the office it is easy to set up a guest network with mandatory authorization. There will be no drawdown of speed due to load sharing between devices. Edimax Pro CAP1300 with a wireless speed of up to 1300 Mbit / s and support for MU-MIMO technology will provide up to 200 devices online at the same time. When overloaded, the client will be connected to the nearest access point.

When ceiling mounting is not available, the position can be exited using a wall model. Edimax Pro WAP1200 provides a smaller coverage area, and even a nearby sistemnik or an IP camera will allow cutting directly through a gigabit LAN port. And for owners of large offices or lovers of large-scale parties around the pool there is an advanced version called Edimax Pro WAP1750 . With a capacity of up to 1750 Mbit / s - only the speed of the provider would be enough. Also, the WAP1750 is equipped with a USB port to quickly “share” any files on the local network.

If the task is to deploy a seamless Wi-Fi coverage and in the surrounding area, such as in the courtyard of the house or office parking, or an open part of the warehouse, street points will help. One of them, Edimax OAP1750 , you could watch at the metropolitan winter skating rink at VDNH.

13.

Well, OAP1300 - a more budget option with support for Wi-Fi Wave2 and MU-MIMO technology - will help owners of suburban facilities, providing a stable coverage in a radius of up to 200 meters. Street access points are completely sealed and are not afraid of the harshest weather conditions. They can be safely secured "overboard" and do not worry about frost and rainfall - a stable Internet in the hammock will be provided.

14.

Summing up

Devices connected to the Internet via Wi-Fi, every day more and more. They depend not only on comfort, but also on safety. Therefore, for timely information about leakage or smoke, the quality of the wireless network is extremely important.

The main advantage of professional equipment is not only high efficiency, but also stability, as well as the lack of "crutches" when tuning. Several ordinary routers, although they will save, but the problem with connecting to a large area will be solved only in part, and even new ones will be added. And time and comfort are no less valuable resource than money. This is a different professional approach. Even if it's a "simple" Internet connection.
