01 / FROM THE MAP TO THE DETAILS

Find a place.
Follow your curiosity.

Move across the country, focus on one network, or inspect a single antenna. It’s all connected.

  1. Explore cellular sites across Canada. Pin colours identify the operators; fans or arrows show antenna directions as you zoom in.

  2. Read the radio layers at a site without losing their context: technology, frequencies, bandwidth and duplex.

  3. A colour-coded diagram brings reported azimuths and beamwidths into view, band by band.

  4. Android reads the serving cell straight from your phone — no shortcut needed. Each SIM gets its own card; the map draws the link to the matched site and its sector, and a card opens signal strength, quality and nearby cells.

  5. Trace point-to-point links between endpoints. A selected line displays its length and reported capacity.

  6. Explore how sites break down by operator, band, technology or equipment. Combine filters to compare the parts of a network.
