Is the bigger the wir÷♣©eless router dBi, the b±←ε etter? At present, common wireless routers can ≠✘β​be learned by checking the parametφ™✘ers, and most of them are 3dBi, 5dBi or 7dBi. Fo> r users, is this valδδ£<ue the larger the better,¶≥ or the smaller the better?

This problem can be uλ✔≠÷nderstood by looking at the diagram of t✘$he next antenna gain.

The higher the DBI value, the greater t♠≥he gain, the smaller the vertiγ¶cal angle, and the longer the transmi☆Ωssion distance, but th↕Ω₩•e smaller the short-distance transmission€£$ area, the smaller the DBλ♣↑I value, the farther the vertica★¶l angle, and the larger the short-distance radi ÷πation area. At present, common wireless rout§±&♣ers on the market gener<↕ally have antenna gain values ​​of 3dBi and 5dBi,←‍©• while some of the main wall-through router‌♥γ antenna gains use 7dBi gain wireless antennas.

For ordinary users, when the home ar®γea is not large, the gain ofδ☆δ 3-5dBi is conducive to signal reception>∑. Although the larger the router a©€₽ntenna, the stronger the w∞©all penetration ability, but the exclusive area iσ♦π♦s likely to become a bl☆≠ind spot. Such router®"€​s often require more router antennas to₹®♠‍ solve the signal coverage problem, aα←←nd the product price is very high.
