Ixia launches new LTE test solution for cellular IoT

NEW DELHI: Ixia, the company that provides network testing, visibility, and security solutions, has announced the launch of its IxLoad-Wireless, a high-performance Long Term Evolution (LTE) test solution for cellular IoT enhanced Machine-Type Communication(eMTC) and Narrowband IoT (NB-IoT) technologies.

According to Ixia, these technologies are new 3rd Generation Partnership Project (3GPP)-defined and will help manage the density expected with IoT and lay the foundation for 5G.

Cellular IoT provides wireless communications for devices and applications that need low-power and wide-range communication connectivity, and have infrequent data transmission.

A low volume of such devices would have a minimal impact on today’s LTE networks. However, according to Ericsson’s Internet of Things Forecast , 70 percent of wide-area IoT devices will use cellular technology in 2022, and the number of cellular IoT devices will surpass mobile phones in 2018.

The press statement indicates that IxLoad-Wireless generates real-world traffic enabling network equipment makers and carriers to fully test the performance of LTE components and networks. IxLoad-Wireless supports multiple Cellular IoT interfaces including S1-Lite, a modified version of the existing S1-MME interface used for the control plane to signal or control messages, and the user plane the data being transferred between users , plus S11u for small data transmission . This allows IxLoad to emulate both the network and IoT user equipment (UE) to test IoT network nodes in isolation or the entire IoT ecosystem.

It is said that IxLoad accomplishes this by simulating IoT network traffic details such as the signaling and messaging for Power-Save Mode and eDRX (extended Discontinuous Reception), where a UE stays inactive for set periods of time to extend battery life.

Test performance is critical to validating the expected density of IoT devices. Offering both hardware and virtual test platforms, Ixia solutions feature best in class performance and meet the capacity scale needed by service providers.
