Field calculators for network and RF work

Standards-based tools for people who have to make a link work, not just describe it. No sign-up, no app, nothing stored.

Power over Ethernet

Loop resistance, voltage at the PD and maximum run length for 802.3af, 802.3at and 802.3bt Type 3 / Type 4, with AWG, patch cords and temperature.

Fibre optics

GPON and XGS-PON ODN loss against both ends of the ITU-T class window, with splitter cascades, both wavelengths and receiver overload.

Wireless links

Path loss, rain fading to ITU-R P.838-3 and P.530, availability in minutes per year, Fresnel clearance and earth bulge.

RF and spectrum

MPE limits to 47 CFR 1.1310, compliance distances for controlled and uncontrolled exposure, and a printable station evaluation record.

Structured cabling

Insertion loss, NEXT, ACR, delay and skew for a channel or permanent link, built from the cable and connector coefficients with temperature derating.

In progress

Structural loading on masts and antennas to TIA-222 and EN 1991-1-4.
