In 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.
- 45 ns (nanoseconds) latency at zero wireless path distance which is 1,000 times lower than typical Ethernet radios
- High gain with longest distances within 70/80 GHz, 40.5-43.5 GHz and 37.0-40.0 frequency spectrum
- 1000 Mbps Gigabit Ethernet full duplex by RFC 2544
- Nordic design, works well for regions like Alaska, Canada, Northern Europe, South Pole
- Intended for High Frequency Trading Networks (also known as High Speed Trading), last mile solutions for networks where transmission speed is crucial.
Practical distances for conditions of ITU rain zone “E”, 2 ft antennas and 99.95% availability of 1 Gigabit 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”.
