and WAN considerations. One part of the network that is becoming increasingly important in the enterprise, however, is the wireless network. In fact, for many workers, the Wi-Fi network will be their primary network for voice communication. If you're seriously considering VoIP over Wi-Fi, take the following steps:
- Ensure pervasive coverage. This means no holes in coverage in areas like lobbies, elevators, bathrooms, cafeteria and outdoor areas. The wireless network should reach 100% of the campus.
- Make the Wi-Fi network denser. More phones means more traffic, which ultimately means more overhead on the access points (APs). Increase the number of APs in a building to handle two to three times more devices over the next five years.
- Deploy redundant APs.This can be handled by backhauling alternate APs to alternate switches, so if a switch fails, all the APs in a single area are not lost.
By following these best practices, you can ensure a successful deployment of VoIP over Wi-Fi.
