Hsinchu Taiwan, 07 February 2013 — Barcelona, Spain – Lantiq and Zyxel Communications, two leading producers of broadband access technology and service provider solutions, announced that Zyxel’s award winning LTE5121 LTE solutions multi-service gateway now supports Voice over LTE (VoLTE). Availability of VoLTE on a fixed LTE gateway platform allows communications carriers to better manage network operations and costs to deliver wireless broadband triple-play services to subscribers. 

The Zyxel LTE5121 gateway was a CES 2013 Innovations Design and Engineering Honoree in the Home Networking Product category; recognized for its innovative design, engineering and cutting-edge features that address what consumers and the market are expecting from 4G/LTE technologies. The rich feature sets, built upon an all-in-one future-proof platform, enable carriers to deploy 4G/LTE services where fixed broadband cannot be quickly or easily reached. The LTE5121 Gateway is also the best platform for Zyxel to enable upcoming VoLTE capability for household markets. With this Gateway carriers can provide the same high quality of voice, data and video triple-play services as wired broadband can serve today, but without requiring wired last-mile infrastructure such as copper or fiber.

The field proven and widely deployed Lantiq XWAY™ GRX288 Broadband network processor that powers the LTE5121 gateway manages the VoLTE software stack, which provides native voice and other rich media services. Lantiq also provides the required voice-line service chip (XWAY™ SLIC110) needed to use standard phone terminals in a home or small business.



Stéphane Téral, Principal Analyst of Infonetics Research: “47% of the LTE operators we interviewed for a July 2012 study said they plan to offer a voice service over their LTE RAN within one year of launching LTE services. IMS remains the default VoLTE platform with circuit-switch fallback as a backup in areas where LTE is unavailable.”

Wayne Hwang, Assistant Vice President of Wireless Strategy Business Unit for Zyxel: “By incorporating the Lantiq network processor, the Zyxel LTE5121 gateway is able to provide the processing headroom to support multiple advanced communications capabilities. This allows us to respond to market evolution quickly and deliver platforms that allow our customers to provide rich media and other premium services to their subscribers.” 

Dirk Wieberneit, Head of the Customer Premises Equipment Business Unit of Lantiq: “Zyxel has long recognized that carriers have to support a wide range of subscriber services while achieving economies in the platforms they have to support. The LTE5121 is precisely the type of powerful, modular gateway carriers need to meet these dual requirements. Our highly integrated GRX288 network processor helps Zyxel to address these challenging market requirements.”
