If there is one technological gadget that has truly made life easier for system administrators, then it has to be the wireless router.
The concept of wireless routers, in case you haven’t heard about them, is not hard to get a grasp of. Wireless routers are essentially ‘normal’ routers, with practically all features and capabilities of the traditional physical-cabling-based routers, only that they are able to connect to local area and wide area networks (and to the computers that they network) wirelessly. This wireless connectivity is of course attained by including wireless access functionality in the routers: so that they can ‘communicate’ with the computers they network and with local as well as wide area networks they are part of, through electromagnetic waves.
This way, then, the wireless routers are able to perform the information routing and forwarding that is expected of routers – without the use of any physical cabling.
As alluded to earlier, wireless routes have made the lives of systems and network administrators much easier since their debut into the technological scene.
One of the ways through which the wireless routers, when incorporated into company networks, make the life of the network and systems administrator easier is by doing away with absolute reliance on the ‘often highly unreliable’ physical cabling. This way, even where such physical cabling is employed, the wireless routers are also deployed as a back up measure; so that in the event of the physical-cabling failing for some reason (to which it is rather prone), the whole company network does not come crashing. With the increased dependence that modern business has on computer networks, the crashing of a company’s network would be a systems or network administrator’s worst nightmare: as they would be sure to get tons of bugging calls requesting for help from the various users of the network.
With the employment of wireless routers as a backup mechanism to the physical-cabling, network and systems engineers find themselves with something to ‘fall back on’ in the event of physical cabling failure- so that the moment there is a break in the physical link, everything doesn’t come crashing down. This way, the network and system administrator can be sure that the organization is not grounded, even as he or she works to find out where the problem with the physical cabling could be (which, incidentally, can be a very tough thing to pinpoint), and sorts it..
The second way through which the wireless routers have helped network and systems administrators is by simply doing away with the need for physical cabling altogether – in the growing number of organization that are opting to go fully wireless. The benefit here cannot be underestimated, as the physical cabling-based network was always sure to develop problems, especially with regard to breakages in the physical cabling, whereas the wireless networks backed by wireless routers hardly ever experience such difficulties. Even where the wireless networks backed by the wireless routers develop difficulties, resolving them is often much easier than trying to isolate and sort out a physical cabling problem.
