Understanding VoWiFi: Voice over WiFi Technology

As we know, voice solutions offer numerous advantages compared to solutions that don’t support voice. Wireless Local Area Networks (WLAN), commonly known as WiFi, have revolutionized data connectivity by providing wireless communication between devices, eliminating the need for cumbersome wiring traditionally used in Local Area Networks (LAN).

Companies and manufacturers are actively developing ways to transmit voice over WiFi networks. This voice transmission over WLAN networks is what we call VoWiFi.

A WLAN or WiFi network consists of Access Points (APs) and Stations.

• An Access Point functions like a router, interfacing with an internet service provider.

• Stations are devices like dongles or WiFi cards that users employ to access the WiFi network.

With the proliferation of WLAN capabilities in modern smartphones, supporting VoWiFi has become essential for companies seeking to save costs and enhance communication among their employees. This ultimately leads to better business management.

A typical VoWiFi network offers several advantages, including increased productivity, cheaper maintenance and installation, better coverage, and a reduction in the actual number of cellular calls made by employees.

Considerations for an Efficient VoWiFi Network

To build a highly efficient VoWiFi network, it’s crucial to keep the following points in mind. Remember that a basic VoWiFi network primarily comprises subscribers (terminals or stations) and Access Points.

• Good Signal Strength: Ensure sufficient signal strength throughout the coverage area.
• Traffic Load and Client Capacity: The network must be designed to handle increasing traffic loads and the number of connected clients.
• Minimal Network Latency: Strive for minimal latency to ensure smooth voice communication.
• Network Congestion Handling: Implement mechanisms to handle network congestion effectively.
• Seamless Roaming (L2 and L3): Ensure seamless roaming between Access Points at both Layer 2 and Layer 3.
