It is very difficult to accurately predict the WiFi range because it is highly dependent on the environment where the device is used (e.g., number of obstructions, number of interferers such as other devices using the unlicensed Wifi bands, etc). That said, a useful indoor range of around 10-15 meters (~33ft to 50ft) is reasonable, more if you have a direct line of sight to the MiFi. You can still connect further away but your speed drops. Theoretical range for 802.11b/g is around 100m (330ft) outdoors and half that indoors; 802.11n roughly doubles this range.
