Verizon Wireless stays quiet about cause of LTE network outage, cites lessons learned

Verizon Wireless (NYSE:VZ) continues to stay mum on the cause of its LTE network outage that left Verizon LTE customers unable to activate LTE devices or access the network for more than 24 hours last month.

Brian Higgins, executive director of LTE ecosystem development at Verizon Wireless, said the company learned some lessons from its outage and is making sure it won't happen again. "Adjustments have been made," he said. However, he did not provide any more details about the exact cause of the outage.

Alcatel-Lucent (NYSE:ALU) and Ericsson (NASDAQ:ERIC) are Verizon's main infrastructure vendors for its LTE network. Cisco Systems provides the common packet data network (PDN) gateways, while Alcatel-Lucent and Nokia Siemens Networks both supply elements of the IP Multimedia Subsystem (IMS) architecture bridging the whole network.

Analysts have speculated that the cause of the outage was a software glitch because the outage was nationwide.
