Wifi router range 1 km price is a path question, not a shelf sticker

What a kilometre claim has to survive

Free-space math is not a site survey. At 2.4 GHz a 1 km path with 20 dBm EIRP, 2 dBi antennas at each end, and a modest fade margin can look workable on paper and still fail behind trees, a metal roof, or a 20 MHz channel full of other SSIDs. At 5 GHz the same distance usually needs more gain or a clearer line of sight because free-space loss is higher. Ask the supplier for the frequency range, the channel width used in the claim, the antenna gain, the feeder loss, and the client radio, not only the router.

Impedance mismatches and connector loss belong in that same note. A 50 ohm panel on an SMA jumper is a different bill from a rubber duck left on the router. Ingress protection, such as IP65 on an outdoor enclosure versus IP30 on a DIN unit, changes the housing and the price basis. Rack unit height rarely applies to a small router, but a 19 inch shelf kit is a separate line if the buyer wants one.

Price comparison waits until quantity, currency, per-unit or whole-order basis, Incoterm, and exclusions match. A wifi router range 1 km price that omits the antenna is not comparable to one that includes a 12 dBi panel and 10 m of cable. IEEE 802, reviewed as an overview on 2026-10-27, frames Ethernet PHY questions for the LAN ports. It does not measure the radio path.

Limits to write in the brief: regulatory EIRP may cap transmit power below the datasheet maximum, a 1 km figure does not transfer from 2.4 GHz to 5 GHz, and client MIMO must match or the link falls back. New versus refurbished also changes the range discussion, because a refurbished radio can have a replaced front end whose gain is no longer the original sheet. Managed monitoring can show RSSI after install. An unmanaged link leaves that check to a laptop on site.

Open price rows when the next question is which accessories sit inside the number, or send the path notes with quantity and destination.
