Methods and apparatus for transferring data along a link with a 10 GBASE-T transceiver at a variable data rate are disclosed. One exemplary method includes detecting a link quality metric; and selecting a symbol transmission rate and a data modulation scheme based on the detected link quality metric. In many implementations, for a selected symbol transmission rate, if the detected link quality metric is less than a link quality threshold, then the selecting of the data modulation scheme is performed such that a data bit per symbol value represented by the selected data modulation scheme is decreased by at least data bit per symbol. The selected symbol transmission rate and the selected modulation together represent a selectable data rate from a selection of data rates.

Aquantia | Date: 2015-09-02

A 10GBASE-T circuit is disclosed. The circuit includes a physical (PHY) integrated circuit and a media access control (MAC) integrated circuit. The PHY couples to a data transfer medium and carries out data transfers at a PHY data rate. The MAC integrated circuit controls access to the date transfer medium and couples to the PHY via a bidirectional link operating at a MAC data rate. Rate control logic detects the PHY data rate, and adjusts the MAC data rate to the PHY data rate. Changes to the PHY and MAC data rates may be made at rates higher than 1 Gbps.


Centralized RAN or C-RAN is an architectural shift in RAN (Radio Access Network) design, where the bulk of baseband processing is centralized and aggregated for a large number of distributed radio nodes. In comparison to standalone clusters of base stations, C-RAN provides significant performance and economic benefits such as baseband pooling, enhanced coordination between cells, virtualization, network extensibility, smaller deployment footprint and reduced power consumption. Although Japan and South Korea continue to spearhead commercial C-RAN investments, interest is also growing in other parts of the world. Mobile operators such as China Mobile, Orange, Verizon and Sprint are already investing in the technology. SNS Research estimates that global investments on C-RAN architecture networks will reach over $7 Billion by the end of 2016. The market is further expected to grow at a CAGR of nearly 20% between 2016 and 2020. These investments will include spending on RRHs (Remote Radio Heads), BBUs (Baseband Units) and fronthaul transport networking gear.

MILPITAS, Calif.--(BUSINESS WIRE)--Aquantia, the market leader of high-speed Ethernet connectivity solutions for data centers, mobile and enterprise, today announced that it will demonstrate its game-changing AQrate® technology in the heart of a bustling hub of development activity in the NBASE-T Alliance booth #1251, at Interop Las Vegas 2015 from April 28-30. Aquantia will showcase its AQrate technology, which is at the foundation of the NBASE-T Alliance physical layer (PHY) specification, and demonstrate design momentum as partners and OEM manufacturers race to incorporate the 2.5- and 5-Gigabit per second (Gbps) Ethernet physical layer integrated circuits into Ethernet switches, Wave 2 of WiFi 802.11ac Access Points (APs) and client devices. Momentum around the NBASE-T Alliance has grown rapidly, and its membership swelled to more than 25 companies in just six months after formation. The market for 2.5/5Gbps connectivity in enterprise is forecasted to grow to 47 million ports by 2019, according to research firm Dell’Oro Group. The alliance’s April 14 announcement highlights this momentum by demonstrating products running real-world applications. Aquantia will demonstrate AQrate AQR405 quad-port PHY ICs on a reference design platform transmitting 2.5 and 5Gbps rates over Cat5e and Cat6 cables to Ethernet switches, WLAN APs and client PCs. It will also showcase the industry’s first Power-over-Ethernet (PoE) to power remote devices while transmitting 2.5/5GE on legacy cabling. “Aquantia changed the face of enterprise networking technology when it introduced AQrate last year and industry response has been outstanding,” said Faraj Aalaei, President and CEO of Aquantia. “AQrate, the technology behind the NBASE-T physical layer specification, provides this game-changing capability at a fraction of the cost of upgrading the cable infrastructure. Aquantia not only enabled new data rates but it empowered an entire ecosystem of developers who are taking bold steps to introduce this technology and help enterprise networks keep pace as connectivity demands increase rapidly.” The NBASE-T Alliance is a consortium focused on the development and deployment of products that support NBASE-T technology and the NBASE-T specification – a specification that defines 2.5 and 5 Gigabit per second (Gbps) speeds at up to 100 meters using the large, installed base of copper cabling in enterprise networks. Aquantia is a pre-IPO semiconductor company and the leader in high-speed Ethernet connectivity solutions for data center, mobile and enterprise markets. As the number one supplier of 10GBASE-T PHYs (10Gigabit Ethernet over copper) in data centers, Aquantia has been consistently the first in the industry to deliver the technology in all process nodes and all port configurations, including the world’s first and only 10GBASE-T MAC/PHY device for servers. Aquantia has further expanded its leadership into the Enterprise Wireless LAN Access Points (WLAN APs) and Campus LAN switches with its flagship AQrate product line, allowing transport of multi-Gigabit Ethernet over legacy Cat5e/Cat6 copper cables. Recently, the company has also entered the cellular infrastructure market with its newly released AQcell product line dedicated to next generation small cell front-haul connectivity. Aquantia is a venture-backed company, with strong tier-1 VCs and strategic investor support. The company is headquartered in Silicon Valley, California, with satellite R&D offices in the Netherlands, Russia and India. Aquantia currently has 140+ employees.

Cisco Systems, Freescale and other tech vendors are creating an industry consortium aimed at driving the development of 2.5 and 5 Gigabit Ethernet technologies to help enterprises deal with the rapidly growing amount of wireless traffic running over their networks. The founders of the NBASE-T Alliance—which also include semiconductor firms Aquantia and Xilinx—want to push the industry to develop more multi-Gigabit technologies than can run over the cabling that many enterprises adopted for their 1 GbE networks. Businesses are seeing an increasing amount of wireless traffic hitting their networks, due in large part to such trends as the growth in the number of mobile devices and the rise of mobile computing, as well as video becoming a larger part of the network traffic. Cisco officials expect that by 2018, the amount of mobile data traffic worldwide will hit more than 30 exabytes per month, and that about 52 percent of the traffic will come from cellular networks, as carriers look to offload traffic onto WiFi networks. The 802.11ac WiFi standard was created to deal with the increase, and the 802.11ac Wave 2 access points will push data rates beyond 1 GbE. However, many businesses still have Category 5e and Category 6 twisted-pair copper cables connecting such access points that can’t support those speeds, which means enterprises need a way to increase the data rates of their existing networks. “The NBASE-T alliance is addressing one of the top networking challenges of today—speed in the access layer,” Chris Spain, vice president of product management at Cisco, said in a statement. “The industry is moving to the next generation of 802.11ac—Wave 2 with theoretical data rates of up to 6.9 Gbps and actual aggregated bandwidth of up to 5 Gbps. A 1 Gbps link between the access point and switch is not sufficient.” The consortium wants to enable businesses to increase the speed of their networks over Ethernet’s standard distance of 100 meters without having to upgrade the cabling they already are using, Spain said. By enabling 2.5GbE and 5GbE speeds on these legacy networks, the alliance members hope to help businesses extend the life of the cabling they already have in place.
