Top Global Launch the World’s First HSUPA Router with built-in QoS and ALG to deliver VoIP over 3G

PRLog (Press Release) – Jan 06, 2008 – Top Global, the global leader in mobile wireless convergence systems, announced today that the MobileBridge™ product family supports latest cellular communication technology – HSUPA (High-Speed Uplink Packet Access (HSUPA) and VoIP over 3G (VoIPo3G). The MobileBridge™ is a patented gateway/router that links 3G and 4G wireless networks with WLAN and LAN, enabling enterprises to enjoy the flexibility and convenience of broadband wireless Internet in truly mobile and remote environments.

HSUPA enables high-speed uplink data communications such as voice over internet protocol (VoIP) and interactive multimedia with improved data speed and shorter latency. Although we first demonstrated VoIPo3G feasibility back in 2003, analysts and 3G carriers have only begun to explore the vast potential of this application recently. Disruptive Analysis forecasts 255 million active VoIPo3G users by the end of 2012. With increasing worldwide penetration of HSUPA and EVDO Rev.A, uplink bandwidth has improved significantly which makes VoIPo3G an attractive application for end users and carriers. Many of our enterprise customers are using the 3G MobileBridge (MB8000) with IP phones which route voice traffic from their remote offices over 3G cellular network work to their corporate IP-PBX. Partnering with our customers, we have developed technologies to overcome two major issues. The first one is quality of service. We have implemented our proprietary native QoS in our Enterprise product line: MB8000, MB9000 and MB6800M (more product info can be found: http://www.topglobalusa.com/) to support VoIPo3G. For example the MB8000 will intelligently route voice traffic with higher priority than other data transfers like file download, etc. Therefore, one can still carry on a clear conversation and download a large file at the same time. The second issue is NAT/Firewall traversal. We have implement VoIP friendly NAT in MB8000. On the other hand, our MB9000 and MB6800M support SIP and H.323 application layer gateway (ALG) to deliver VoIPo3G. The ALG enables secure transport of VoIP traffic through the firewall and NAT so packets don’t bounce off the firewall.

As the market demand for uplink speed grows, there are clear advantages to support seamless migration from HSDPA to HSUPA in our MobileBridge™ product family. Using the MobileBridge™ with AC881 and AT&T HSUPA network, average uplink throughput of 500-800 kbps and downlink throughput of 600-1400 kbps can be achieved. With HSUPA and EVDO Rev.A technologies, our MobileBridge can better support innovative mobile applications and advanced features including:
   Broadband Wireless Internet Access. Similar to EVDO Rev.A, the HSDPA technology delivers higher data rate than DSL, and cable. It offers additional freedom and flexibility for customers to get anywhere anytime internet access.
   New Applications. High speed uplink makes HSUPA (and EVDO Rev.A) an ideal technology for applications such as VoIP, video surveillance, and interactive multimedia communication.
   Mobility. Optimized handover schemes with short latencies ensure real-time applications such as VoIP performance without service dropout or degradation in moving environments.
