VoIP Over WiFi Algorithms for Dual Mode Handsets
- L2 Handover - Call Delay
Intra WiFi access point L2 handover introduces significant latency resulting in call delays.
- L3 Handover - Call Drop
Intra WiFi access point L3 handover breaks IP connectivity resulting in dropped calls.
- Unplanned RF
Unplanned RF can cause dead spots, interference from rogue access points, and over congested access points.
- Legacy AP - No Intelligence
Legacy access points have no handover intelligence. A client-side solution is needed to manage handover.
- Access Point Agnostic
No access point vendor lock-in. Works with any IEEE 802.11 WiFi access point.
- Client-Side Algorithms
Algorithms are implemented completely on the client-side. A first in the industry.
- Open and Published Interfaces
Openly available API for easy integration with applications.
- WiFi Chipset Agnostic
No chipset vendor lock-in. Works with any standards-compliant WiFi chipset.
- Multiple Associations with Multiple Access Points
Association with more than one access point at any time eliminates handover latency. Without multiple associations, the handover process takes from hundreds of milliseconds to several seconds depending on the Wi-Fi driver behavior and the type of authentication mechanism used (open/shared/WPA/WPA2). With multiple associations, latency can be reduced exponentially.
- Intelligent Access Point Selection Algorithms
Nuvoiz's patentable technology includes an intelligent algorithm for selecting the best access point for the best quality of service. The algorithm performs the following tasks:
- Client-side site survey, discovery, and mapping of access points via RSSI.
- Radio dead spot detection.
- Congestion detection
