Altran Technologies launches LTE Licensed Assisted Access and LTE Wi-Fi Aggregation solutions

Altran accelerates the availability of latest Wi-Fi technology co-existence standards that improve the user experience and deliver significant cost and time-to-market advantages.

REDWOOD CITY, California, 14 September, 2016: Altran today announced the immediate availability of LTE Licensed Assisted Access (LAA) and LTE Wi-Fi Aggregation (LWA) solutions for LTE eNodeB as part of the company’s commitment to provide comprehensive next-generation connectivity solutions to its customers.

The alternative spectrum technology solutions incorporate Altran’s LTE eNodeB software running on hardware partner’s SoC platform. Leveraging the existing carrier aggregation capabilities, the Altran LTE-LAA solution uses one or more 20 MHz carrier(s) in the license-exempt spectrum, which can be cost-effectively shared with Wi-Fi for opportunistic access to increase the traffic capacity of an in-building LTE network. The Altran LWA solution combines LTE and Wi-Fi technology to provide a unified wireless network to user devices. Together, these solutions deliver significant cost and time-to-market advantages for both OEMs and service providers that seek to launch new and compelling in-building communications capabilities.

The Altran LTE-LAA solution is available for customers to incorporate into their product development plans. It is designed for fair coexistence of LTE and Wi-Fi by using the Listen-Before-Talk (LBT) protocol with a back-off approach on the license-exempt secondary carrier currently used mainly for Wi-Fi. The Dynamic Frequency Selection (DFS) mechanism is built into the solution to address the requirements of operating in specific unlicensed frequency bands. This solution is ideally suited for small-cell deployments where low-power and high-frequency reuse is critical to meet increased capacity requirements, and the 5 GHz license-exempt band is seen as the right fit for the same.

“We are continuing to collaborate with Altran in developing our next-generation Wireless Access solutions supporting 4.5G with capabilities such as LTE-LAA,” said Jee-wong Chung, Chief Technology Officer, Contela Inc. “We are confident that Altran will be able to keep pace with the quick evolution of 3GPP standards beyond Release 13 and ensure the readiness of its software, which reduces the overall time to market for us.”

“We are excited to introduce the LTE-LAA and LWA solutions that quickly and cost-effectively address the high-end throughput needs of enterprise and residential users in the in-building environment,” said Walid Negm, Chief Technology Officer, Altran. “Contela has once again shown its confidence in our eNodeB software. With more than 80 LTE engagements to date with equipment manufacturers, Altran has developed the expertise and experience to deliver next-generation connectivity capabilities in the LTE RAN space.”

Altran's LWA solution is designed to offload LTE traffic onto the Wi-Fi infrastructure in a seamless manner for compatible user devices and provide significant improvement in the end-user experience.
