Infovista hits new milestone for DSS testing for 5G deployment as operator adoption accelerates

Infovista has announced it has shipped its thousandth upgrade for its TEMS Investigation platform to allow operators to test Dynamic Spectrum Sharing (DSS). This innovative technology lets operators take advantage of existing 4G infrastructure to deliver initial 5G capabilities, without compromising the performance of existing customers.

DSS was made available as part of 3GPP Release 15 in April 2019 and is now supported by leading infrastructure providers including Ericsson, Nokia, Huawei and ZTE through a software upgrade. With DSS, operators can allocate portions of the 4G LTE spectrum that they are already using to 5G NR allowing users to coexist in the same frequency band/channel at the same time. Last month, the first wave of handsets with new Qualcomm X55 5G modem and Exynos 990 chipsets supporting DSS arrived in the market – further fuelling interest from operators.

“DSS offers a simple way for mobile service providers to bring new 5G users on board gradually to match their adoption models—while continuing to support legacy 4G customers,” says Jose Duarte, CEO for Infovista. “In the past, when operators wanted to upgrade to a new technology, they would have to do  Spectrum Re-farming, moving old users off a part of the spectrum and reserving the block for new users—even if they were limited in number. DSS instead offers an easier transition but there is still a need for testing to ensure the process is seamless.”

Infovista is offering its DSS testing capability as a ‘free upgrade on request’ to all TEMS Investigation 21.0 customers and according to Duarte, “The pace of adoption is rapid and roughly 70% of the 176 5G companies we currently work with worldwide, are now evaluating DSS within their networks,” he says.

An analysis of the TEMS upgrades highlights a broad geographic spread of DSS testing underway across 56 countries led by the US, Germany, UK, and the UAE region.

As the first network performance specialist to demonstrate a DSS testing solution back at MWC America 2019, Infovista has continued development to ensure compatibility with all infrastructure vendor solutions. “This is a key point as most operators have a mix of manufacturers across their infrastructure and having unified testing, planning and optimisation tools is a significant benefit in simplifying 5G deployment,” says Duarte.

The Infovista TEMS Portfolio supports all the major smartphones that have DSS compatibility, and this feature will extend to the upcoming 7.4 release of Infovista Planet radio planning and optimisation solutions scheduled for launch during the middle of 2020.
