San Jose, California, USA, June 19, 2018-WiFi solution innovator Quanta CommunicaTIons, Inc. (NASDAQ code: QTNA) today announced the launch of QSR10GU-AX Plus, a set of draft standards based on IEEE 802.11ax for gateways And the new enhanced solution of the access point is now undergoing sample testing for some customers. QSR10GU-AX Plus is based on Quantenna's groundbreaking WiFi platform QSR10G-AX and provides a variety of unique features, including adaptive 5GHz, SuperTx and ESP algorithms, bringing significant performance improvements to various home configurations. The QSR10GU-AX Plus can run simultaneously in 8x8 MIMO systems in the 5GHz band and 4x4 MIMO systems in the 2.4GHz band, and it can support a total of 12 spatial streams. Popular science is about 802.11ax. There are three main types of core features. One is 1024-QAM, which is a higher-order modulation that can further increase the physical connection rate. The second is OFDMA, its biggest feature is that it achieves multi-user parallel transmission in another form. We all know that 802.11ac Wave2 relies on MU-MIMO for parallel transmission. OFDMA uses another form to achieve parallel transmission and is more stable. The third is SR spatial multiplexing. There are many details about the networking technology involved. The unique features of QSR10GU-AX Plus include:

• Adopting an adaptive algorithm supported by the unique design of Quantenna baseband and RF architecture to achieve dynamic switching between 8x8 MIMO and dual-band 4x4 MIMO in the 5GHz frequency band. This will provide end users with the best possible MIMO configuration, tailored to different environments.

• With enhanced radar detection and spectrum analysis functions, the frequency band analysis range is wider.

• By allowing two non-802.11ax devices to carry out multiplexed SuperTx, it can bring up to 2 times the performance gain for traditional client devices that are not 802.11ax.

• The ESP algorithm will enhance the beamforming and MU-MIMO performance of traditional devices.

In addition, RF enhancements allow the frequency band to be expanded by up to 3dB, ensuring better performance and lower material costs.

QSR10GU-AX Plus is fully compatible with QSR10G and QSR10G-AX in hardware and software, allowing customers using QSR10G to quickly replace without changing the current product design.

Dr. Sam Heidari, Chairman and CEO of Quantenna, said: "With QSR10GU-AX Plus, Quantenna once again leads the market with highly differentiated products, demonstrating our extensive experience in developing innovative driven solutions to meet customers' future needs."

Andrew Zignani, a senior analyst at ABI Research, said: "802.11ax can solve the major challenges brought about by the rapid growth of devices with WiFi networking capabilities, the expansion of per-user traffic demand, and the increase in network congestion.

Quantenna's latest solution adds new members to the vitality ecosystem created by the 802.11ax chip specifically designed to expand transmission capacity, expand coverage, and enhance the overall user experience in crowded network environments. ABI Research predicts that by 2022, 802.11ax will account for nearly 30% of WiFi chipset shipments. "About Kuantengda Communication
