Two US navy ships will soon take the waves equipped with LTE networks. The USS Kearsarge and USS San Antonio are heading to the Persian gulf in March with a microwave-based wireless wide area (WWAN) LTE network.
Network infrastructure vendor Ericsson has reported Q2 earnings down 1% from the year-ago quarter, but up 13% from Q1. “Sales in the quarter year-over-year were driven by growth in the Middle East, China and India, as well as continued capacity business in North America,” said Ericsson CEO Hans Vestberg.
In the first of our series of features on Software Defined Networking, Marcus Weldon, CTO at Alcatel Lucent and Bell Labs, gives Telecoms.com his take on the buzzword of the moment.
Number two US operator AT&T has announced plans to expand its LTE network over the next three years in a project dubbed Project Velocity IP, or VIP.
Mobile operators worldwide should be preparing for an impending surge in traffic over the next several years, with mobile users in 2016 consuming an average of 6.5 times as much video, over eight times as much music and social media, and nearly ten times as much games than in 2011.
US carrier Verizon Wireless this weekend suffered an outage that affected its LTE network across the country. According to reports, the service went down early Sunday evening, and had only been partially restored across the country on Monday morning. Some users reported that 3G services were affected as well, leaving customers replying on 1xRTT for data access.
As telecoms networks are in the shift to be packetized and broadband-based, All-IP has been the future development trend of service networks. According to prediction, bandwidth is expected to grow at an annual rate of over 30% in the next five years. The two-layer networking mode “IP over WDM” is gradually replacing the traditional three-layer “IP over SDH over WDM” mode at both backbone layer and metro layer, and the flat architecture enabling carriage of IP packets directly over photonic layer has been an inevitable trend. IP over WDM networking architecture poses new requirements for photonic layer WDM equipments, and WDM layer will take over the networking, service grooming and end-to end circuit monitoring and management functions originally provided by SDH networks.
As the competition in the global telecom market becomes increasingly fierce, the 2G and 3G bearer services coexist, the traffic bandwidth increases constantly and the interfaces tend to be IP-based, the bearer networks are required to provide powerful multi-service bearer capability, statistical multiplexing, differentiated QoS, carrier-class service guarantee, high precision clock synchronization, and excellent network extensibility.
