HFT-friendly 45 ns Low Latency for ELVA 1.25 Gbps Link Confirmed by TWS Technologies

In response to demands from Ultra Low Latency networking market for High Frequency Trading (HFT) applications, ELVA-1 produces PPC-1000-E Low Latency 1.25 Gbps Gigabit Ethernet link for FCC permitted 71-76 GHz, 81-86 GHz (70/80 GHz) bands. In terms of network infrastructure, these are links for Low Latency / Ultra Low Latency wireless networking.

Measurement of a tiny latency of wireless device cold be a painstaking work. Advertisements coming from link manufacturers are trying to hit the potential customers with awesome low latency numbers, sometimes even beyond of physics law. Thus, having an independent professional confirmation of link latency becomes crucial for decision makers on client side.

During May, 2017, TWS Technologies, the division of Dutch-based TWS Group has fulfilled a series of latency measurement tests for ELVA PPC-1000-E wireless MMW link according to RFC2544 methodology. The test traces have been established nearby Twello city on distances of 1.6 km and 1.16 km (1 mile & 0.7 mile). These tests confirmed 45 ns (45 nanoseconds, or 4.5e-5 milliseconds) for latency “input port to output port” for PPC-1000-E link hardware.

“There are many aspects of Low Latency networking for HFT applications, including special hardware devices like low latency links, network cards and switches, ultra low latency execution software, and many other things,” said John Viester, TWS Technologies. “Ultra Low Latency millimeter-wave links most often are used in private wireless networks between financial centers in different cities or even countries. Mm-wave/microwave networks have two key advantages over fiber: radio signal propagates through air about 40 percent faster than light moves down fibre, and second, network providers could build microwave trace in about straight line between the two cities,…
