Mobility Features
Whether deploying a public safety network, where mobility is a core requirement, or a municipal Wi-Fi network, where demand for mobile VoIP and UMA support continues to grow, it is important to take into account all of the components that are required to properly support the operation of latency sensitive applications on the network.
RoamAD's system has been designed from the ground up (from a software, hardware and network architecture perspective) to deliver unmatched flexibility and functionality for high-performance converged wireless networks supporting mobile voice, data and video.
RoamAD has developed the RoamAD's Inter-node Communication System™ at the core of its platform for added mobility support.
RoamAD's Inter-node Communication System™ includes:
- Wireless event processing and inter-node communication and coordination
- Smooth client handovers with pre-authentication
- Rapid roaming for latency sensitive applications such as VOIP and video surveillance
- Link status and performance analysis
- Dynamic link selection and redundancy
- 'Push'-based management traffic system that conserves backhaul links and increases performance of time-sensitive networking processes
- 'Every-node' authentication and coordination via RoamAD's inter-node communication software layer
Other important mobility features inherent in RoamAD's solution include:
- Complex mobile networking support and fast roaming backhaul
- Optimized radio drivers
- Rapid roaming event notifications
- IP-level network updates
- QoS for management traffic
RoamAD's infrastructure-mesh network architecture assists with the support of latency sensitive applications due to:
- 3-dimensional coverage
- Use of multi-radio nodes (option to use separate radios and spectrum for backhaul and end user coverage)
- Fast, robust backhaul
- Low hop count
- Low latency
- Predictable performance with overlapping and high quality client signals
RoamAD has proven mobile VoIP/VoWiFi experience:
- Successful use of VoIP/VoWiFi on customer networks since April 2004
- Successful testing of mobile VoIP/VoWiFi at 145 Km/h over US interstate in January 2005 (see press release and Arizona Highway Case Study)
