Huawei demos 1Gbps indoor performance with Vodafone

Huawei and Vodafone showing 1Gbps indoor performance on new generation Lampsite solution.

Huawei and Vodafone have a joint demonstration at Small Cells World Summit World* (SCWS World) showing 1Gbps downlink throughputs over Vodafone’s live, commercial networks.

The demo is taking place over Vodafone spectrum, and is designed to show how the company achieves 1Gbps+ throughputs indoors via its distributed small cell solution – the Lampsite 2.0. The demo lifts performance from the existing 300Mbps that Lampsite, launched two years ago, currently offers.

In the demo, two new generation Lampsite access points are connected to a device capable of supporting three component carrier aggregation. With three carriers bonded together, the test shows around 450Mbps downlink speeds.

When Huawei’s implementation of distributed MIMO is applied, that doubles to around 900Mbps. Distributed MIMO means combining connectivity from two individual access points, each providing 2×2 MIMO to one device. That effectively creates 4x4MIMO connectivity to the device (obviously the device must be capable of supporting 4×4 MIMO), effectively producing a sort of 2x (2×2) MIMO implementation.

Finally, 256QAM is added to the coding scheme, putting an extra 30% or so on top of the 900Mbps, pushing the speed up and over the 1Gbps rate.

Marvin Cheng, presenting the demo to a seminar held at the event, said that the solution had been proven in a live deployment by Vodafone during Mobile World Congress. He added that with increasing demand for support for HD voice and video codecs, 1Gbps would become “the new user experience and driver for Mobile Broadband developments.

That has meant Huawei adding a clutch of new capabilities to its Lampsite product, including the three carrier aggregation, higher order modulation and distributed MIMO. There is also wider spectrum band support and LAA coming online, as Huawei continues to develop the product.
