The router signal is not always distributed equally to all corners. Depending on where it is located, coverage problems may be experienced in some areas. Then it is appropriate to take some measures to achieve optimal distribution. In addition, for those homes with many rooms or two floors, there are devices capable of extending Wi-Fi from one end of the house to the other.
Once the signal is emitted by the device, it begins to bounce against the obstacles in the surroundings. The walls, furniture, doors or even appliances, are some of the elements that must pass through the waves. To this list of impediments we must add the Wi-Fi networks of neighbors who operate in the same band.
The router signal bounces on furniture, walls and doors and weakens.
Experts warn that at night, during peak hours, where everyone is connected to their network to watch a movie, download a video or play online - even if one has hired 100 megabytes - the so-called “interference saturation” usually causes the inevitable delay of any wireless connection.
And since routers are not decorative artifacts, many hide them in a shelf or hide them in a drawer. To help a uniform distribution and prevent Wi-Fi from losing power in its path, the key is to place the device in an elevated position and in a clear area.
To know the ideal orientation, there are some free applications such as Wifi Analyzer that check the quality of the connection, its scope and the points where it overlaps with other signals. And while the interface is somewhat confusing, after studying the graphics, one ends up realizing what each line offers.
Among the data collected by this software is the signal strength, the frequency at which the router emits, the channel it uses, the number of networks around us and which ones overlap. It will be enough to move through the different rooms and identify which one lowers the signal and where it has the highest speed.
To resolve distance conflicts, when it is necessary to cover a radius greater than 80 meters, it is necessary to resort to hardware.
Before a repeated slowness, the change of band, is often the simplest solution to the problem. Most routers broadcast on two frequencies: 2.4 gigahertz (Ghz), and 5 Ghz. The indicated thing is to pass, from the configuration of the router, to the band of 5 GHz, which is less saturated and has capacity for greater speed. The problem is that not all devices have an antenna that is compatible.
To resolve distance conflicts, when it is necessary to cover a radius greater than 80 meters, it is necessary to resort to hardware. There are two technologies in conflict: "Power Line Communicators" (PLC), a system that encodes the router's signal and distributes it through the electrical installation and Wi-Fi Mesh, which uses multiple extenders that are linked to generate a network intelligent.
“While PLC takes advantage of the home network connectivity without wiring or modifying the infrastructure, while delivering a uniform transfer rate and extending coverage to any plug, Mesh is a repeater to which they add a protocol to improve the connection experience ”, details Agustín Rodríguez Varela, Country Manager of the company Devolo.
The Mesh Tp Link Deco M4 Dual Band Ac1200 Wi-Fi system, which consists of two antennas, is 1200 Mbps and is around $ 8,500.
Home PLCs consist of two parts, a signal transmitter that connects to the router via a network cable and plugs into a nearby outlet and another, larger and heavier, which acts as a remote point. If necessary, you can add more modules.
Once the second adapter has been plugged into an outlet, the two parts must be synchronized. Simply press a button to establish the link automatically. To know if they are docked, the red light of the devices should change to blue.
For your choice, you must consider the number that accompanies the PLC, which represents the speed of the fiber optic or the modem cable of the user. Some models are 300, 500, 600, 1200 or 2000, which designates the maximum transmission speed in Mbps.
The Dlan1200 + Devolo Amplifier (two devices), reaches 1200 Mbps and is around $ 13,000.
One of the teams with optimal response is the Dlan1200 + Devolo Amplifier, which reaches 1200 Mbps and is around $ 13,000 for both devices. If one wants to add a third repeater, the value of the latter is $ 6,500. While the Powerline Tl-wpa4220kit of 300 MB / s, you get for $ 7,500.
Wi-Fi Mesh, which went from business to homes, uses multiple satellites or nodes (from two onwards) that connect to each other generating a stable network from any position. Unlike traditional repeaters, which only replicate, it makes an intelligent distribution of the signal.
Thus, when faced with a demand for access, Mesh or mesh networks calculate the status of all nodes and, based on the number of connected devices, the distance and signal strength, choose the best satellite to link, which is not always the one that is closest.
The Samsung Smartthings Wifi Mesh Router Rang, with a speed of 1200 Mbps, is worth about $ 37,000 for all three devices.
This intelligent traffic management is the big difference with repeaters, to which phones or notebooks are usually connected according to their proximity and not by the state of the network at a given time. In addition, if any of the nodes fails, the network is automatically reconfigured to continue operating.
In this category, the Samsung Smartthings Wifi Mesh Router Rang, with a speed of 1200 Mbps, is around $ 37,000 for three devices. While the Mesh Tp Link Deco M4 Dual Band Ac1200 Wi-Fi system, consisting of two antennas, 1200 Mbps, is around $ 8,500 and if you want to add a third node, you will have to pay about $ 4,800
