EdgeQ pursues a feature subscription model for 5G basestation chip

EdgeQ, a start-up offering a 5G systems-on-a-chip, introduced a 5G chipset-as-a-service model in which customers can scale 5G and AI features as a function of subscription payments.  The service-oriented model would enable customers to scale from nominal to advanced 5G features such as ultra-reliable low latency communications, geo-location services, massive MIMO, fine-grained network slicing, as well as extending compatibility to other legacy wireless protocols. 

The company says its new service model is the very first in the chip industry to scale price, performance, and features as a function of need and use.  The potential is to elevate 5G Open Radio Access network (O-RAN) to an even more configurable, elastic, open wireless infrastructure. Enterprise network, telco, and cloud providers might also use the EdgeQ model to virtualize network resources.

“Our vision at EdgeQ has always been about implementing 5G in a format that is accessible, consumable, and intuitive for our customers. EdgeQ is not only the first company to converge both 5G and AI on a single chip for wireless infrastructure, but we are also able to make those capabilities available in a SaaS model.  This fundamentally reduces the initial capex investment required for 5G, thereby removing both technical and economic barriers of 5G adaptation at greenfield enterprises,” said Vinay Ravuri, CEO and Founder, EdgeQ. “This pay-as-you-go model ensures that the evolving demands of the market can leverage the full fluidity and elasticity of EdgeQ’s 5G-as-a-Service product.”

Huawei cites 1.6 Tbps single wavelength field trial over 180km

Huawei has successfully tested a 1.6 Tbps, per single-wavelength optical transmission in a high-capacity data center interconnect (DCI) scenario. 

The field trial, which was conducted with an unnamed European tier 1 operator, was performed on 96.5km of field-deployed standard G.652 fiber using EDFA-only amplification. A total of 34 channels were transmitted with 150GHz spacing for a total fiber capacity of more than 56 Tbps and spectral efficiency of higher than 11 bit/s/Hz.

Additional demonstrations featured single-wavelength transmission of 1.77 Tbps over 60km, 1.65 Tbps over 120km and 1.6 Tbps over 180km. T

Huawei said the record performance was driven by its advanced channel-matched shaping (CMS) algorithms. It includes the advanced non-linear digital signal processing and advanced modulation based on 400QAM using enhanced probabilistic constellation shaping (ePCS).

The company also cited a demonstration of 1.28 Tbps net bitrate per single-wavelength in a ROADM-based metro network link of 452km G.652 fiber also employing EDFA-only amplification.

Dr. Maxim Kuschnerov, Director of Huawei's Optical and Quantum Communications Laboratory said: “We achieved an important milestone towards the era of 1.6 Terabit per second transmission in DCI and metro networks. Furthermore, deploying a Super-C+L band line system, the total fiber capacity could exceed 100Tb/s and provide sufficient room for future network growth driven by the rapid expansion of cloud services.”

Samsung and UC Santa Barbara demo 6G Terahertz prototype

Samsung Electronics, in collaboration with the University of California, Santa Barbara (UCSB), demonstrated a 6G Terahertz (THz) wireless communication prototype which consists of a 16-channel phased-array transmitter and receiver modules. These were driven by CMOS RFICs (Radio Frequency Integrated Circuits), and a baseband unit to process signals with 2GHz bandwidth and fast adaptive beamforming. In the over-the-air test, the prototype system achieved real-time throughput of 6.2 Gbps over a 15-meter distance with adaptive beam steering capability at the Terahertz frequency.

Samsung says the THz band includes an enormous amount of available spectrum, which will enable wideband channels with tens of GHz-wide bandwidth. This could potentially provide a means to meet the 6G requirement of terabits per second data rate. 

Samsung and UCSB researchers have been working closely on the development of a THz phased array. The precise digital beamforming calibration algorithm, developed by Samsung, enables these modules to achieve high beamforming gain.
