PPC-1000 Low Latency 1.25 Gbps E-band/Q-band/Ka-band Radio 


45 ns Ultra Low Latency PPC-1000-LL 1.25 Gbps link works is intended for High-Frequency Trading (HFT) and other application within millimeter-wave/microwave network infrastructure.  

Low Latency 1.25 Gbps E-band/Q-band/Ka-band RadioIn response to demands from Ultra Low Latency networking market for High Frequency Trading (HFT) applications, ELVA-1 produces PPC-1000-LL (Low Latency version) 1.25 Gbps Gigabit Ethernet link for FCC permitted 71-76 / 81-86 GHz (70/80 GHz E-band), 40.5-43.5 GHz (Q-band). and 37.0-40.0 (Ka-band). In terms of network infrastructure, this is link for Low Latency / Ultra Low Latency wireless networking.

Practical distances for conditions of ITU rain zone "E", 2 ft antennas and 99.95% availability of 1Gigabit full duplex connection:
  E-band radio max distance is 7.1 km (4.3 miles)*
  Q-band radio max distance is 14.4 km (8.7 miles)*

 * Use Online link budget calculator to determine actual distances consider frequency band, antenna size and % of connection availability.

In High Frequency Trading (HFT) applications shaving even a single millisecond from trading times can equate to a distinct infrastructure advantage and generate significant profits. According to Information Week Magazine: “A one (1) millisecond advantage in trading applications can be worth $100 million a year to a major brokerage firm”.
