Getting the office ready for networking can be expensive. What will the small business owner do when they are needing to switch locations? There are options available to a small business owner. Going wireless is possible but be prepared to do it properly it can be a little daunting for a first time installer to do.
For the small business a wireless router is typically like the one found in the home. The bad news about the router being home grade is that the security may not be like the business grade router.It may lack the security that is needed.
A business grade router will offer features that a home grade router will not. The business grade router will offer a larger antenna and will provide more coverage for the office. If security of the network is a concern than it may be best to have a network server authentication such as RADIUS in place. Some offices may need to have several wireless access points to work together and cover the whole office. A home wireless router will not be able to do this. You may want to have the option of knowing who is accessing your wireless network system. If there is going to be guests in the office and they may need to connect to the internet you will want a way for them to connect without being able to access the rest of your network.
An issue with a wireless network is if other offices are next door or within the area then you would not want them to be able to access your network. What can you do about that? The other option would be to use cabling. It is expensive to cable a office however, it does offer the benefit of higher network speeds. It is really totally up to what the business needs and preferences are.
