Imagine a hall full of people talking to each other. Wireless transmission is affected a lot by all obstacles in the way, and 30-40 meters range with a WiFi router is in many cases just a wild dream.Īnother point I don't really see raised is that less WiFi range can be better from a cross-talk point of view, allowing greater density of WiFi devices within a certain area. Note however that when comparing, you should do so in the same exact conditions. has better range, or better speed at the same range) than the communication between two non-router devices.
This explains why the communication between a device and a router is usually better (i.e. Routers usually have less constraints than other devices, especially other phones: larger/better antennas, higher transmit power, and possibly better sensitivity. When your phone is communicating with another device, all these parameters are replaced by the values for that other device. When your phone is communicating with your router, the link budget equation uses your router's antenna gain and sensitivity for one direction, and your router's transmit power and antenna gain for the other direction. When you compare your phone "talking" to your router or to another device, some things are common (your phone's transmit power, antenna gain, sensitivity), but other parameters change: Of course, in most cases (and definitely in the case of WiFi), you also need to do the link budget in both directions, as data is sent in both directions. So the max distance depends on both the transmitter and receiver. The receiver's antenna gain, losses, and sensitivity.The loss over the air (free space path loss) and through any obstacles.The transmitter power, antenna gain, and losses.The range of a wireless link is defined by the link budget.
