New software upgrades unlock indoor performance
The resulting influx of devices, users, and applications trying to access the network can result in poor indoor coverage and performance. And with the coming growth in the Internet of Things contributing to 26 billion connected devices in 2020, providing the right coverage to indoor spaces will become a greater challenge.
To support these changes in connectivity, Ericsson has added capacity and functionality with software-only upgrades. It announced its next major software release, Ericsson Networks Software 16A, which will feature a new suite of LTE software upgrades targeting the indoor space.
Advanced uplink and downlink performance
The new suite features advances in uplink and downlink performance - boosting network uplink speeds by up to 200 percent, downlink speeds by up to 30 percent and adding LTE Unlicensed (LTE-U), the first commercial step in Licensed Assisted Access - as well as features to support greater energy efficiency of small cells. To achieve these gains, Ericsson has been working with leading customers on lab tests and trial activities.
Mike Sapien, principal analyst enterprise services, Ovum, says: "While operators have understood that they need to design mobile networks for increasing amounts of data now, Wi-Fi networks have traditionally been the solution of choice for indoor connectivity for enterprise customers. However, Wi-Fi cannot service the need for reliable and mobile voice services or text messaging, much less handle the business-critical applications that require the app coverage, voice services, and full mobility provided by cellular. Now, as we move toward 5G, both cellular and Wi-Fi will need to work together to offer differentiated and seamless service."
Increases in video and media uploads by businesses and consumers via apps like Instagram and Facebook call for better uplink speeds. Ericsson Networks Software 16A includes two uplink enhancements that will enable mobile operators to utilize 64 Quadrature Amplitude Modulation (QAM) on uplink to provide 50 percent better peak speeds of 75 Mbps. In addition, it enables uplink carrier aggregation, which can double uplink data speeds. Combined, these improvements provide peak uplink data rates up to 150 Mbps, which is a 200 percent improvement. Further enhancements focused on the indoor space boost download speeds by 30 percent using 256 QAM encoding.
Driving higher performance
Networks Software 16A also includes LTE-U, to drive higher performance. LTE-U enables operators to combine the reliability of licensed spectrum with indoor data speed boosts provided by unlicensed spectrum.
Arun Bansal, senior vice president and head of business unit radio, Ericsson, says: "To keep pace with mobile broadband demand from both consumers and industry, operators need solutions that deliver both high performance and efficiency. Ericsson's indoor software innovations deliver both. And, these new features combined with Ericsson's end-to-end solutions, flexible go-to-market and business models and proactive relationships with key device ecosystem partners, ensure that our leading operators not only keep pace, but set the pace."
Ericsson Networks Software 16A builds on energy-efficiency capabilities in previous releases and now includes Cell Sleep mode. This feature enables individual carriers to automatically switch off during periods of low traffic demand, ensuring greater energy efficiency of small cells.
