The pros and cons of Wireless networks to business firms

Danson Wachira is a certified Trainer in Computer Science, Information Technology and related studies.

Many businesses in the world ranging from small micro-enterprises to medium and large companies are moving towards implementation of computer networks. The demand to acquire new clients while at the same time keeping the old ones coupled with stiff market competition drive these business firms to diversify their business trends. In their quest to do so, they are employing new technologies that guarantee return on investment and profit maximization.

One such technology employed by business firms is installation of Wireless computer networks to facilitate faster customer services and maintain an upper edge on their competitors. A Wireless network is a computer network that uses boundless data transmission signal to route information between two or more network connected devices.


A wireless signal can use transmission media such as high frequency radio signals, satellite and VSAT (Very Small Aperture Terminal) technology, Laser technology, Infrared light, Microwaves etc. to transmit data signal between two or more connected devices such as workstations, servers or mobile devices.

A Wireless network use Wi-Fi (Wireless Fidelity) IEEE 802.11 standards and Ethernet protocols that were originally defined by the Wi-Fi Alliance and adopted in 1997.

With increased cost of business operations and the need to maximize profit, many business firms were skeptical whether to install a computer network in the first place and even so, whether to go wireless or connection oriented way.

With the high cost of Wireless network and high cost of equipment necessary for implementing a Wireless network, very few companies opted for Wireless network.

But as more companies and users acquired laptops with integrated wireless network cards and adapters, the cost of wireless devices has decreased and wireless networks are becoming much more common.

If a company is considering installing a computer network as a Wireless network or probably upgrading an existing network to be a Wireless network, here are the pros and cons of a Wireless network.

Advantages of Wireless networks


  • Fast and easy to setup

Wireless network are easy and fast to setup mostly because most wireless devices such as laptops and mobile devices come with wireless adapters that makes it easy to locate and configure a wireless signal. Many wireless devices can connect automatically to a wireless network with no need to fix wires or cables.

  • Mobility

Probably one of the biggest advantages of wireless network is the ability of enabling users to move around within the signal range at their discretion. With a laptop or mobile device, users can be able to access wireless signal be it in a café, mall or in airplane. Many companies also provide on-air Wi-Fi access commonly referred to as “Hot Spot.” If a company needs signal mobility especially where customer “hot” help desk is a requirement then Wireless network is a better option.

  • Cost

Setting up a Wireless network nowadays is much more affordable since there is no cost of buying and installing wires and cables. Moreover, Wireless network devices such as signal extenders, range boosters, signal repeaters and wireless routers have become much more affordable.

  • Expandability

Adding new wireless devices such laptops into a Wireless network is easy. In many cases it is as simple as turning the device on and plugging it into a network so long as users limit is not exceeded.

  • Signal coverage

Initially, signal coverage in Wireless network used to be a major problem but with improved and new technologies, this is becoming a thing of past. Wider signal coverage in Wireless network can be achieved through network extenders, range boaster and earth stations.

Disadvantages of Wireless networks


  • Security

Network security has been a problem in Wireless networks. Compared to connection oriented networks, Wireless networks are much more vulnerable to malicious attacks, hacking and bandwidth theft. Security measures such as disabling broadcast, use of MAC filtering, data encryption, data back-up, network isolation, passwords/usernames authentication etc. can be used to improve network security.

  • Interference

Wireless signal are much more susceptible to interferences from weather changes, other electronic devices, refraction, reflection, absorption, blockage from physical objects such as thick walls etc. These can cause the signal to be unstable leading to weak connections or disconnections.

  • Speed

If the firm needs fast data exchange such as in real-time processing or where huge data such as 3D images need to be moved across the network, Wireless network can be a disadvantage. Although Wireless networks are generally faster than dial-up connections, they cannot match up to the data speeds provided in connection oriented networks usually in terms of gigabyte Ethernet.

Hi livewirez,

Thanks, glad that this article was helpful. Thanks for the visit and comment.

Romel Tarroza from Philippines on April 21, 2013:

Great hub.. Thanks for the information..

Ondari S Jephiter from Nairobi, Kenya on March 18, 2013:

Mobility cannot be overemphasized. The easiness of using a number of different devices such as PDAs, printers, cameras, etc makes wireless network the most preferred despite the security concern.

Thank You

Mobility.... can not be overemphasized. The easiness in using a a number of different devices such as cameras, PDAs and even printers.

Great hub

Hi healthylife2,

Wireless network especially on internet can be very flexible on mobility, it is one benefit i enjoy on Wireless. Thanks for the visit and comment, I really appreciate.

Hi kashmir56,

Thanks for the visit and comment, technology can be advantageous and disadvantageous but we have to live with it. Enjoy your day.

Thomas Silvia from Massachusetts on December 04, 2012:

Awesome hub with all great useful information on the pro and con of using a wireless network .

Vote up and more !!!

healthylife2 on December 04, 2012:

Great job presenting both sides of the issue. I think most companies today have the wireless network because they can do work anywhere. During the hurricane when we lost power for a week my husband had access with his wireless and what was even more exciting was I could still get into hubpages through his computer:) Voted up and sharing!

Joseph De Cross from New York on December 04, 2012:

Interesting and useful Danson Wachira. Your pros and cons are explained in detail and with an understandable language for the "tech newbie." Nice seeing this kind of hubs! Take care my friend! Nice to see you!

Hi Brett.Tesol,

Security can be a big issue in Wireless networks especially where sensitive data need to be moved across the network. Customer disputes can be common when privacy and confidentiality is an issue. Thanks for the visit and comment, i really appreciate the support. Good day.

Brett C from Asia on December 02, 2012:

Good summary. Security can be a big issue, especially against anyone who knows a bit about IT. Not only can software break passwords, but some routers don't require you to be plugged in (cable) to change the settings. This means anyone can go to your settings page, see you password and even change it!! Ask before you buy.

Shared, up tweeted, and useful.

Hi ChristyWrites,

One of the biggest reasons why i like wireless internet is because i can move around with my laptop, yes mobility is a great advantage. Thanks for the visit and comment.

Christy Birmingham from British Columbia, Canada on December 01, 2012:

Another well-balanced hub here. I think mobility is the primary advantage of a wireless network. Being able to manage risks such as security issues is important for businesses to do. Vote up!
