Nokia Siemens Networks and Samsung demonstrated standards-based Voice over LTE (VoLTE) interoperability using two different clients running on Samsung LTE devices.
The calls used the 700-MHz frequency LTE band and encompassed a complete end-to-end VoLTE configuration including laptops installed with VoLTE clients from Nokia Siemens Networks and Samsung. The laptops are connected to the network via Samsung’s “Redwood” LTE dongle, which incorporates Samsung’s in-house developed “Kalmia” modem chipset.
“Following the announcement of our first commercial LTE dongle and the demonstration of our LTE netbook, this demo is a defining moment for us. Full interoperability with Nokia Siemens Networks’ LTE network infrastructure and its own VoLTE client takes us one step closer to commercial deployments and showcases the viability of our products,” said Yunsang Park, vice president of the Telecom R&D Center at Samsung Electronics.
“We have achieved interoperability with Samsung for both data and voice calls across several frequency bands required for LTE deployments in different markets,” said Tommi Uitto, head of Network Systems product management, Nokia Siemens Networks. “With this demo, we further underscore that we are commercially ready for global LTE deployments and that our end-to-end LTE ecosystem is fully interoperable with leading vendor devices.”http://www.nokiasiemensnetworks.com
