Aricent tech combines LTE and Wi-Fi tech to offer unified wireless network

Aricent launched LTE Licensed Assisted Access (LAA) and LTE Wi-Fi Aggregation (LWA) solutions for LTE eNodeB leveraging both cellular as well as Wi-Fi networks available in the vicinity.

Aricent’s LTE eNodeB software running on a SoC platform is being incorporated as the alternative spectrum technology solutions. The Aricent LTE-LAA solution uses one or more 20 MHz carriers in license-exempt spectrum along with Wi-Fi for opportunistic access to increase the traffic capacity of an in-building LTE network by influencing the power of existing carrier aggregation capabilities. Aricent provides unified wireless network to user devices by combining LTE and Wi-Fi technology.

LTE-LAA solution is designed for fair coexistence of LTE and Wi-Fi by using the Listen-Before-Talk (LBT) protocol with 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 5GHz license-exempt band is seen as the right fit for the same.

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

Walid Negm, Chief Technology Officer, Aricent says, “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”. “Contela has once again shown its confidence in our eNodeB software. With more than 80 LTE engagements to date with equipment manufacturers, Aricent has developed the expertise and experience to deliver next-generation connectivity capabilities in the LTE RAN space.”

LTE traffic is being off loaded onto the Wi-Fi infrastructure by Aricent's LWA solution in a seamless manner for well matched user devices. It provides significant improvement in the end-user experience while watching streaming content.
