Aquantia breaks mobile infrastructure bottleneck to deliver unprecedented throughput speeds

Power over Ethernet (PoE) enabled AQrate PHY devices allows next generation of 802.11ac Wireless LAN Access Points (APs), enterprise switches and client devices to operate at unprecedented speeds.

Aquantia breaks mobile infrastructure bottleneck to deliver unprecedented throughput speeds

Aquantia has developed a PHY product line that delivers 5 times higher throughput than the current Gigabit Ethernet (GbE) solutions without requiring any change to existing copper cabling infrastructure. The AQrate PHYs, designed in the 28nm process node, combine 2.5GbE and 5GbE as well as IEEE-compliant 10GBASE-T, 1000BASE-T (1GbE) and 100BASE-TX (100MbE), for transmission over up to 100m of twisted pair cabling. AQrate based products are backward compatible with legacy GbE and 100MbE products allowing for gradual upgrade of equipment. The AQrate PHY family integrates such features as Energy Efficient Ethernet (EEE), 1588v2, MACsec and supports all Power over Ethernet (PoE) standards up to 60W.

According to Cisco Visual Networking Index (VNI), total mobile data traffic will surpass 30 Exabytes per month in 2018. An estimated 52 percent of that traffic will be offloaded from the cellular network to the fixed network through WiFi, adding to the vast amount of wireless data otherwise transmitted over WLAN in enterprise and campus environments. The 802.11ac WiFi wireless standard was developed to respond to this tsunami of data. As the second wave of the technology gets introduced, traffic aggregated on APs will surpass 1 Gigabit/sec. Dell'Oro Group market research indicates that 802.11ac upgrades, especially wave 2, will require additional Ethernet Switch bandwidth beyond what GbE technology can support.

AquantiaAQratePHYsForeseeing the enormous potential for deploying next generation 802.11ac APs on legacy cabling infrastructure, Aquantia devised AQrate to transmit Ethernet data at 2.5 and 5 Gigabit/sec (2.5GbE and 5GbE) over Cat5e cables up to 100 meters in length. AQrate integrates PoE technology, which is a critical feature in WLAN access point deployments.

“The industry is gearing up for a massive upgrade of enterprise networks to handle the explosion of mobile computing traffic driven by next-generation 802.11ac access points,” said Bob Wheeler, principal analyst for networking at The Linley Group. “Aquantia has developed an enabling technology that can substantially increase network bandwidth without having to replace the massive amount of legacy Cat5e and Cat6 horizontal cabling used in most enterprise-campus networks. AQrate technology will be a welcome development for network administrators who are taking on the challenges of growing wireless-LAN traffic.”

The following selections from the AQrate Product Family are now available in production quantities:

· Quad – AQR405 is housed in a 25mm flip-chip BGA package enabling efficient high density design for high port-count and compact campus LAN and wiring closet Ethernet switches

· Dual – Wireless Access Points, compact switches, and myriad applications leverage low power of AQR205 to create passively cooled solutions. Its 19mm flip-chip BGA package features flexible system interfaces including full KR (with auto-negotiation) /XFI/RXAUI/XAUI/2500BASE-X and SGMII

· Single – The 19mm AQR105 is pin compatible to AQR205 providing the option for single or dual-port solutions with minimal design edits. The AQR105 features flexible system interfaces including full KR (with auto-negotiation) /XFI/RXAUI/XAUI/2500BASE-X and SGMII
