Wireless VoIP Challenges
Many enterprises deploying VoIP also want to integrate voice over their wireless networks to enjoy the quick response and enhanced collaboration associated with in-house voice mobility. However, wireless adds an extra layer of complexity to the VoIP equation. Quality of Service (QoS) must be maintained across wired and wireless networks to ensure that delay-sensitive VoIP receives consistent, high priority end-to-end communication to provide optimal call quality. Further, as employees move through the enterprise, authentication hand-offs must occur flawlessly so latency and jitter are minimized and voice calls are maintained seamlessly.
HP ProCurve wireless VoIP solution delivers real-time, toll-quality voice – enabling employees to communicate securely wherever they roam in the enterprise.
ProCurve Wireless VoIP Solution
HP ProCurve solution provides pervasive wireless coverage to facilitate real-time, enterprise-wide wireless VoIP. Unlike most WLAN vendors, ProCurve delivers voice traffic directly from source to destination – eliminating latency and jitter caused by extraneous trips to the controller. QoS is applied at the network edge, so time-sensitive voice is prioritized end-to-end for high performance and toll-quality calls. Ultra-speed handoffs – under 5 ms in most implementations – enable seamless roaming while continuously enforcing identity-based and device-based network policies. That ensures calls are never dropped and security is never compromised.
ProCurve solutions ensure your intrusion scans never interfere with real-time voice communications. Uniquely-designed dual- and tri-radio MultiService Access Points (MAPs) dedicate radios separately to client access and security – so that both operate simultaneously, non-stop. Other vendors use a "timeslicing" method of intrusion scanning that stops client traffic to perform security scans – rendering VoIP unusable.
HP ProCurve Wireless VoIP solution is delivered via the following products:
- MultiService Access Points (MAPs)
Many features within ProCurve MAPs contribute to high-quality voice calls. They forward voice traffic directly from source to destination – to minimize latency and jitter and apply QoS to ensure end-to-end, upstream and downstream voice prioritization. That includes standards-based support for TOS/DiffServ and 802.1p and frame bursting for voice traffic. Alternatively, MAPs can classify traffic based on TCP/UDP port or device type (such as VoIP phone) to ensure QoS support for legacy devices. Read more about MAP security features.
- MultiService Controller (MSC) 5000 Series
The MSC 5000 Series enables continuous cross-enterprise roaming within and across subnets by coordinating ultra-speed handoffs of network credentials and service characteristics from MAP-to-MAP using sophisticated L2 and L3 mobility techniques that minimize authentication delays. Additionally, the MSC centrally configures all MAPs with appropriate levels of QoS and security per user, application and device. Read more about MSC-5000 features.
