Wired vs Wireless classification of Network are based on the type of routers that are usually used for connecting various computing devices together. A wireless router will create a wireless network while a wired network is the interconnection between various computers using cable as the connectivity medium. The significance of cable installation is security, speed and reliability.
A wireless network doesn’t use wires or cables to connect devices as we found in a wired Network. Your mobiles gadgets such as a laptop, tablet or GSM phone (with Wi-Fi capabilities) can easily connect to the network if it’s in range of its signal. This actually allows more freedom to move around your working space.
Whilst wireless definitely offer convenience and flexibility, there are also several other imperative factors. We should consider when trying to use them in place of the unsurpassed & advantageous wired networks.
Security – One of the biggest concerns in regards to wireless network is effective security procedures. Because the data is transferred through the air it can easily be intercepted. Strong encryption (WPA/WPA2/AES) implies that data is unreadable unless you have the correct key to interpret it. However, many wireless network still remain unsecure or with weak WEP encryption and are prone to security breaches.
Wired networks do not face this problem. Physical access can only be obtained by somebody who has access to the infrastructure, a wireless network on the other hand can be access from outside a building, in a car park for example!
Speed – When we talk wired vs wireless we are becoming extremely impatient when it comes to the rate of data transfer and speed. Those factors are certainly of the essence in computer networking and data transfer. Majority of wired networks are presently being upgraded to gigabit since a lot of hardware nowadays is gigabit ready and a lot of cabling is gigabit compliant. Wireless on the other hand is unlikely to ever match the speeds offering by wired. Wireless N boosts speeds of 300mbps. Of course, in a typical environment you are only likely to get around one-third of this speed.
Another point to consider with the speeds is the fluctuation. Transferring your data over a wire will normally give you a steady and consistent speed. The same cannot always be said for wireless because there are other weather factors that affects the signal strength. Interference and signal drops means that transfer speeds can jump up and down a lot with wireless.
Reliability – is another important thing that has to be taken in consideration whan we are talking about wired vs wireless. Moving on from the point above wireless networks are far more prone to Noise interference thereby. This interferences causing to severely suffer from reliability issues. Due to the absence of no physical medium, data has to transfer through the air and must pass through any surface in its path. This means that signals can get blocked and deflected.It means your connection can suffer or even drop.
Even large distributed wireless networks can suffer from these problems. And without careful planning of where access points are located wireless can be a nightmare for connection problems. Wired networks rely solely on physical cabling that will stay in the same location and have a long-life span. Cabling rarely ever fails in networking. This means you get the same speeds and performance day in, day out for many years.
As you can see there are several considerations to take into account when deciding whether to use wired or wireless (cabling or wireless) networks. A combination of both can be very effective provided your budget can cover it. And the right security procedures are put in place. However, as a strong and compelling advice, It would be quite foolish for any company to completely replace their wired network with a wireless one.
