6Advantages and disadvantages

Wireless networks have a number of key benefits over wired networks such as mobility, cost-effectiveness and adaptability, but there are also some disadvantages such as security. Below, main advantages and disadvantages of a wireless network vs wired network are listed.

The following list summarizes some of the benefits of wireless networks:

Increased efficiency

Improved data communications lead to faster transfer of information within businesses and between partners and customers. For example, sales people can remotely check stock levels and prices whilst on sales calls.

Better coverage and mobility

Wires tie you down to one location. Going wireless means you have the freedom to change your location without losing your connection, without the need of extra cables or adaptors to access office networks.

Flexibility

Office-based wireless workers can be networked without sitting at dedicated computers, and can continue to do productive work while away from the office. This can lead to new styles of working, such as home working or direct access to corporate data while on customer sites.

Cost savings

Wireless networks can be easier and cheaper to install, especially in listed buildings or where the landlord will not permit the installation of cables. The absence of wires and cables brings down cost. This is accomplished by a combination of factors, the relatively low cost of wireless routers, no need for trenching, drilling and feeding wires inside the walls or other methods that may be necessary to make physical connections. In addition, no wire maintenance is needed.

Adaptability

Fast and easy integration of devices into the network, and high flexibility when modifying an installation.

New opportunities/applications

Wireless networking could allow you to offer new products or services. For example, many airport departure lounges, train stations, hotels, cafes and restaurants have installed hot spot wireless networking services to allow mobile users to connect their equipment to their home offices while travelling.

There are also certain drawbacks associated with the use of wireless networks.

Security

Wireless transmission is more vulnerable to attack by unauthorized users, so particular attention has to be paid to security.

Installation problems

You may suffer interference if others in the same building also use wireless technology or where other sources of radio signals are present. This could lead to poor communication or, in extreme cases, loss of wireless communication altogether.

Coverage

In some buildings getting consistent coverage can be difficult, leading to black spots where no signal is available. For example, in structures built using steel reinforcing materials, you may find it difficult to pick up the radio frequencies used.

Transmission speeds

Wireless transmission can be slower and less efficient than wired networks. In larger wireless networks the backbone network will usually be wired rather than wireless.
