Follow¿Que es WIFI?
Se trata de un sistema para conectar redes y ordenadores sin necesidad de cables.
WiFi se utiliza como denominación genérica para los productos que incorporan cualquier variante de la tecnología inalámbrica IEEE 802.11, que permite la creación de redes de trabajo sin cables (WirelessLAN).
Cuando hablamos de WIFI nos referimos a una de las tecnologías de comunicación inalámbrica más utilizada hoy en día.
Como funciona WIFI?
Las redes WiFi utilizan la tecnología de radio denominada IEEE 802.11a, 802.11b o 802.11g para proporcionar una conexión inalámbrica segura, fiable y rápida. Una red WiFi se puede utilizar para conectar ordenadores entre sí, a Internet y a las redes cableadas (que utilizan IEEE 802,3 o Ethernet). Las redes WiFi operan sin necesidad de licencia en las bandas de radio de 2,4 y 5 GHz, con una velocidad de transmisión de datos de 11 Mbps (802.11b) o 54 Mbps (802.11a) o con productos que contengan las dos bandas (banda dual). Pueden proporcionar un rendimiento similar a las redes cableadas 10BaseT o Ethernet.
Seguridad en WIFI
Las redes WIFI son totalmente seguras (configuradas adecuadamente). Dependiendo de su uso final, a las redes WIFI se les pueden implementar diferentes grados de seguridad.
El uso de protocolos de cifrado de datos, el filtrado de MAC (de manera que sólo se permite acceso a la red a aquellos dispositivos autorizados), ocultar el nombre de la red o la autentificación de los usuarios son técnicas que nosotros implementamos en todas nuestras instalaciones para asegurarle al cliente que solamente podrán acceder a la red WIFI los aparatos o personas que estén autorizados.
Usos de WIFI.
Una definición rápida de el uso de la tecnología WIFI sería la de establecer una conexión, entre dos puntos o más, sin necesidad de estar conectaods a través de un cable. Varios ejemplos del uso de la tecnología WIFI podrían ser:
Unir varias oficinas o naves.
Si sus oficinas se encuentran repartidas en diferentes naves o edificios, se pueden conectar las redes de los edificios a través de un enlace WIFI, incluso en el caso de solamente disponer de internet en uno de los edificios, este se puede compartir.
Acceder a internet en cualquier lugar con un portátil o teléfono móvil.
Uno de los usos más frecuentes de las redes WIFI es para proporcionar el acceso a internet de equipos portátiles (tanto ordenadores como teléfonos) en cualquier punto de unas instalaciones para los usuarios y/o los clientes. Para ello se crea un área de cobertura que les proporciona este servicio.
Conseguir acceso a internet allí donde no llega un ADSL.
En la actualidad todavía existen lugares donde no ha llegado de una forma económica las conexiones de alta velocidad a internet (como el ADSL o el cable). Una posible solución consiste en “enviar” este acceso a internet a través de un enlace WIFI.
Acceder de forma inalámbrica a la red empresarial desde cualquier punto.
A veces se necesita tener acceso a la red empresarial sin la incomodidad de tener que estar atado a un cable de red. Una solución puede ser el crear una zona de cobertura para que sus empleados puedan acceder a la red empresarial a través de PDAs o portátiles.
Ventajas del WIFI.
Realizar una instalación WIFI tiene muchas ventajas:
Rapidez de instalación.
Facilidad de funcionamiento, como también movilidad (el usuario decide dónde trabaja, ya que ahora el puesto de trabajo se restringe a la zona de cobertura inalámbrica).
Transparencia (la red funcionará como si hubiera puesto un cable).
Gran escalabilidad (puede dar de alta a centenares de usuarios en la propia red).

All this is possible to installers of wireless networks, professional people who go above and beyond in the work.
Wi-Fi Installations.
We have noticed that it is not always possible to have a data cable at all locations where it is necessary:
Unite several offices or flagship offices.
Access the internet from any location with a portable laptop or mobile phone.
Get internet access in locations where ADSL telmex or CABLE cablemas does not offer service.
Get wireless internet access to business networks from any place.
For this we have specialized in offering wireless installations for our clients using the latest technologies on the market with WI-FI and WIMAX devices.
What is a wireless link?
A wireless link is the wireless connection between two points using WI-FI technology.
It is the same as having a cable network between two points.
How is a WI-FI link useful?
Imagine what you could do if you could link two points on a network without having the necessity to use a cable:
Links at great distances (100KM).
Create high velocity connections between networks from the same company.
Transport of ADSL Telmex lines or Cable Cablemas and telephone
Advantages of a WI-FI link
Simple communication from point to point: It is possible to communicate between several equipment without the necessity of using a cable to connect the devices, the WI-FI waves are the way the equipment would connect.
Rapid installation and minimum costs: No work, without laying a long cable between the two points, no maintenance, no need to pay rent to a dedicated leased line, with a very short installation time and without interrupting your daily work.
What is a WI-FI zone?
It is the space covered with Wi-Fi waves in which you can connect your device to a network using WI-FI and has access to the rest of networks using cable, including internet ( in the case that the network has access to the internet).
What services can a WI-FI zone give?
Having a WI-FI covered zone is like having a multitude of network cables having from the air in order to connect to the network, to provide service to their users or clients.
Access to a business or company network at any point
Access to the internet without the need for cables.
Connect without the cables to a pc, a laptop, a PDA or mobile telephone with a WI-FI connection.
Hotspot service for your clients.
Security for WI-FI networks?
We provide completely configured installations shielded against attacks:
Encrypted communications.
Protected with a highly secure AES code.
Protection by MAC.
Protection.by user and password.
In WIMEX we extensive experience in installing WI-FI coverage zones.
What is WI-FI?
It is a system for connecting networks and computers without cables.
Wi-Fi is used as a generic term for products incorporating any variant of the IEEE 802.11 wireless technology that enables the creation of wireless networks (Wireless LAN).
When we talk about WI-FI we are referring to one of the wireless communication technologies most used these days.
How does WI-FI work?
The Wi-Fi networks use radio technology called IEEE 802.11a, 802.11b or 802.11g to provide safe, reliable and fast wireless connection. A Wi-Fi network can be used to connect computers to each other, the Internet and wired networks (which use IEEE 802.3 or Ethernet). The Wi-Fi networks operate in unlicensed radio bands 2.4 and 5 GHz, with a data transmission rate of 11 Mbps (802.11b) or 54 Mbps (802.11a) or with products containing the two bands (dual band). They can provide a similar performance to cable networks 10BaseT or Ethernet.
Safety in WI-FI
Wi-Fi networks are completely safe (when configured properly). Depending on the end use, the WI-FI networks can be implemented with different degrees of security.
The use of protocols for data encryption, MAC filtering (so that the network is accessible only to authorized devices), hiding the network name or user authentication are techniques that we implement in all our installations to assure the customer that only authorized devices or people will be able to access the WI-FI network.
WI-FI uses.
A quick definition using Wi-Fi technology would be to establish a connection between two points or more, without being connected through a cable. Several examples of using Wi-Fi technology could be:
Merge multiple offices or branches.
If your offices are located in different branches or buildings, the buildings networks can be connected through a WI-FI link, even if only one the buildings has internet, this can be shared.
Access the internet anywhere with a laptop or mobile phone.
One of the most common uses for Wi-Fi networks is to provide Internet access to portable devices (both laptops and phones) anywhere for users and / or customers. To do this a coverage area that provides this service is created.
Get internet access where ADSL is not available.
At present there are still places where high speed Internet (such as ADSL or cable) is not available due to economic reasons. One possible solution is to “send” the internet via a Wi-Fi link.
All wireless access to the corporate network from anywhere.
Sometimes you need access to the corporate network without the hassle of being tied to a cable network. One solution may be to create a coverage zone for your employees to access the corporate network through PDAs or laptops.
Advantages of WI-FI.
Having a WIF installation done has many advantages:
Speed of installation.
Ease of operation, as well as mobility (the user decides where it works, because now the job is restricted to the wireless coverage area).
Transparency (the network will operate as if using a cable).
Scalability (can enlist hundreds of users in the network itself).
In WIMEX we have extensive experience with Wi-Fi technology.
