Industry's Only Solution for Cost-Effective Network Upgrade to 4G/LTE-Advanced
Cisco's most recent Visual Networking Index (VNI) predicts a 26-fold increase in mobile traffic between 2010-2015, with mobile video accounting for over 60% of that traffic by 2015. Service providers must adopt new mobile access technologies such as TD-LTE and LTE-A to accommodate this massive traffic growth. To provide high bandwidth and broader radio coverage, these emerging access technologies rely on new stringent packet timing requirements. To address the issue, Heavy Reading forecasts IEEE1588v2 to become the most widely deployed packet synchronization standard worldwide, providing synchronization to over a million cell sites in live commercial service by the end of 2015.
"Sub-10 nanosecond accurate timing is essential for operation of TD-LTE
and LTE-Advanced networks which will bring Gigabit broadband
connectivity to mobile devices," said
Demonstrated Performance in Real-World Tests
Vitesse recently reported network performance results to the ITU-T documenting VeriTime's < 3ns per hop accuracy over a nine-hop IEEE1588v2 Transparent Clock (TC) network, making it the industry's only solution that fulfills TD-LTE and LTE-Advanced requirements in real-world tests today. VeriTime's highly accurate and cost-effective IEEE1588v2 TC technology eliminates the need for discrete timing FPGAs, processors, and software timing synchronization solutions in the cost-sensitive Edge and Access equipment. VeriTime supports both Boundary Clock (BC) and lower cost TC implementations of the IEEE1588v2 standard.
VeriTime also relaxes requirements of other timing and clocking components, significantly reducing overall systems cost. Patented extensions of VeriTime include distributed TC over microwave, a way to implement accurate IEEE1588v2 timing over microwave links, to overcome latency variations due to weather and changes of modulation scheme.
"VeriTime represents Vitesse's fifth generation of IEEE1588v2 IP and is
a significant architectural advancement towards providing GPS-grade
timing over the network without sacrificing systems margin," said
Vitesse's Carrier-specific Ethernet IC portfolio is MEF CE 2.0 compliant and offers the industry's lowest power access switch with MPLS/MPLS-TP support. Learn more at www.vitesse.com/VeriTime.
