Wi-Fi Has Its Pluses and Minuses Over Copper

The Wi-Fi standard of network connectivity/communication is governed by the  802 working group of the Institute of Electrical and Electronics Engineers (IEEE  802). Wi-Fi allows users to access your company or home network wirelessly.  Before the implementation of Wi-Fi, the only way to connect to a network was by  using copper wires. There are a variety of benefits and hazards that must be  considered before rolling out full wireless network access.

Plus: Enhanced Mobility

Laptop and notebook computers allow users to move around easily. Add in a  Wi-Fi connection, and they can stay connected to the network as long as they  have enough signal strength. This means your users can be online while eating  lunch while enjoying the sunshine outside. It also means that a user can stay  connected while carrying his or her laptop or notebook from the office to the  conference room.

Plus: No Wires to Trip Over or Limit Computer Placement

Wires are hazardous. You can roll over them with your chair and ruin them.  You can trip over them while carrying an arm load of papers from the printer to  your desk. This can be painful and injurious to both people and equipment.  Damaging equipment by yanking a wire caught under your foot is a common  occurrence. Also, using a wireless card in a desktop computer frees you from the  bondage of having to plug into a wall outlet

Plus: Add Users Without Adding Cable Runs

One of the biggest expenses when expanding the size of your network is adding  locations where users can connect to the network. In a network running a  traditional copper infrastructure, this means calling in a contractor to pull  and terminate cables. With a wireless network, it consists of installing a  wireless adapter card in the computer and supplying the user with an access key  and the name of the network being connected to.

Minus: Slower Network Speeds

Networks that are compliant with the latest cabling standard (Category 6/6  Augmented) are capable of transmitting data at speeds up to 10 Gigabit. The  previous standard, Cat 5e, is capable of Gigabit speeds. This is almost ten  times as fast as wireless networks, which are capable of a maximum of 150  Megabits. What this means is that if you will be transferring large data files  over the network, you would be better served by a wired network. However, there  aren’t many network interface controllers in use that are capable of these  speeds yet, especially when it comes to laptop computers.

Minus: Network Security Is Weaker on a Wireless Network

Anyone with a wireless adapter and computer or a Wi-Fi-enabled device, such  as an iPhone, can receive the wireless signal propagated by your network’s  wireless access points and routers. There are ways to enhance the security of a  network based upon wireless technology, but these aren’t fool-proof and can  actually be broken quite easily by someone who has the right knowledge and  desire. Network security in a wired network isn’t bullet-proof, either, but the  tools available much more robust and will keep out all but the most determined  of hackers. Also, they have to breach your security normally from the Internet,  which usually means multiple layers of security. Once the security of a wireless  network has been breached, that person is inside your network with the same  access as an authorized user. Typically, someone breaking in to your network  from the Internet has to breach that security and then be able to breach the  security between subnets as well.

Free 120 Min Health Check

When I was made redundant (thankfully) from my last job which was within a Call Centre environment, I was just a tad pleased that I would no longer be crawling under desks to try and resolve IT issues for members of my Team. The daily cries that computers had ‘frozen’ or would not turn on at all had become a bit too predictable. The predictability would be not only attributed to the cries but also to the causes and I was quite adept at bringing the system back to life. My healing hands were aided by being able to spot “Charlene” who would inevitably have plugged in her heater, for the winter, or her fan, for the summer, only needing to unplug another plug to do so….happily oblivious that it belonged to a colleagues monitor or base unit!! Another of the more amazing faults to be found would be as a result of the number of items being stored under a desk and in fact rammed into floor sockets….discarded sweets, chewing gum, hair accessories, the odd shoe, Cardigans, pens, elastic bands by the dozen and paperclips are to name but a few….deep joy!  Now it is my firm belief that every office is more or less the same in this respect. However….there are other reasons why our Data Cabling may be lacking in some way and causing all sorts of problems to a lean, mean fighting machine business and how quickly its system is running.

It may well be that over the years the infrastructure of a business has been built piecemeal as technology has developed alongside the needs of the company. Equally when a business is first born the Data Cabling that is installed may not be sufficient for the growth of the Company some years down the line. Cables and wires do suffer from wear and tear, they can become crushed, bent or even stretched which will weaken the strength of the signal. Perhaps the initial installation was not a fantastic job? Perhaps humankind has played a part in its demise….we do have a habit of moving things around!!

Now do these pictures remind you of anything that you are working with?

When we are feeling run down or unwell…not up to speed….we see a Doctor, but when do you give your network a Health Check?
