Ranurador óptimo para una mejor conectividad sin hilos It is a fact that businesses are becoming increasingly dependent on the use of computers and the internet. Indeed, not only has such technology enhanced the efficiency of many operations, but it has also proved to be very cost-effective. Space is no longer an issue, with employees being able to work remotely, as geographical boundaries have all but been removed.
Over the years, there have been advancements in technology, which have worked to further improve efficiency. As a result, there are a number of devices and tools on the market that are helping businesses to operate more smoothly and cost-efficiently.
Take wireless networks as a prime example. In addition to removing the need for an office to be strewn with many cables, it is also possible to be connected to the internet almost anywhere. As a result, employees can work almost any place, and at any time.
Using similar technological principles as mobile phones and televisions, wireless networks use radio waves to transmit data. Through the use of a wireless adapter, which is connected to a laptop or desktop computer, data is translated into a radio signal and transmitted to a wireless router via an antenna. After receiving the signal, the router then decodes it and sends the information to the internet.
In order to become connected, it is essential that the computer or laptop has the right equipment. However, in comparison to traditional cable connections, where one usually requires someone to install it, it is simple to set up a wireless connection. In fact, many of the computers and laptops that have become available on the market in recent times already come with a built-in wireless adapter. And if not, it is also possible to easily purchase a plug-in version.
Once installed, the computer or laptop should then be able to automatically locate the necessary networks available. Sometimes, however, it is necessary to employ the use of a software programme, in order to detect them.
When considering the use of wireless, it is important to understand the different wireless LAN standards out there. Currently there are three available – 802.11b, 802.11a and 802.11g - although in the future this number will increase.
The most popular networks are based on 802.11b, which was made available in 1999. Although it has the slowest maximum speed, supporting up to 11 megabits per second (mps), it is also the most cost-effective option.
802.11a will provide you with faster speed – 54 mbps – and can support more concurrent users at one time, but it offers a smaller transmission range. 802.11g on the other hand, is a relatively recent development and works to combine the best of both 802.11b and 802.11a.
But regardless of which wireless LAN you opt for, it is important to consider the needs of your business. Therefore, before you get connected to any wireless networks, make sure you consider all of the necessary options.
