Configuration
A wireless network connects employees to the Internet while giving them the ability to work on any wireless device. Fortunately, configuring such a network is fairly straightforward.
1. WAPs
Determine how many wireless access points (WAPs) your office will need to maximize the router’s signal range and strength. Plan on the routers’ signals traveling 300 feet, but take into account if the network has obstacles or has to cross rooms or the office is several floors tall.
2. COVERAGE
One of the best - and most simple - ways of determining the Wi-Fi coverage your office needs is by walking through the office with a laptop and noting the connection. Dead spots will be readily evident.
3. ADAPTORS
Next, ensure that all laptops and PCs have Wi-Fi adapters. For maximum speed and performance, make sure you chose compatible wireless routers and adapters.
4. SECURITY
Securing your wireless network is the final step, as a wireless LAN will remain a hotspot open to the public if security measures are not put in place. Consider adding network security features like a firewall and a virtual private network (VPN), as well as intrusion prevention, and content filtering. Data encryption, access control lists (ACLs), and address filtering can also help control who can access your wireless network.
Finally, for guest users, create virtual LANs (VLANs) to help keep your network secure.
The next step in the Strategic Plan is determining a Time Table.
