30 feet, 10 meters
You can have up to seven Bluetooth controller devices on a PS3
The maximum range of Bluetooth 2.0 specification for Class 1 devices is approximately 100 meters (about 328 feet) in an open space. This range can be affected by obstacles, interference, and environmental conditions, potentially reducing the effective distance in practical applications. Class 1 devices are designed for higher power output, enabling this extended range compared to lower-class devices.
The maximum distance between two near field communication devices is typically around 4 centimeters or 1.6 inches.
The maximum distance between two near field communication (NFC) devices is typically around 4 centimeters or 1.6 inches.
With Bluetooth some advantages include wireless that does not require a direct line of sight, a maximum range of hundred meters, and the simple ability to pair devices. However, some disadvantages include heavy battery usage for portable devices, and less secure connectivity than infrared.
The maximum distance between two NFC devices is typically limited to about 4 centimeters due to the short-range nature of NFC technology.

Bluetooth technology has three main output power classes: Class 1, Class 2, and Class 3. Class 1 devices can transmit up to 100 meters with a maximum output power of 100 mW, Class 2 devices typically reach about 10 meters with 2.5 mW, and Class 3 devices have a range of around 1 meter with 1 mW output power. These classes determine the range and power consumption of Bluetooth devices.
The maximum distance for two devices to communicate depends on the technology used. For example, Bluetooth typically has a range of about 30 feet (10 meters), while Wi-Fi can extend up to several hundred feet indoors and up to a mile outdoors with the right equipment. Cellular networks can cover miles, with some technologies like 5G potentially offering even greater distances. Ultimately, environmental factors and specific device capabilities can significantly influence these ranges.
Bluetooth operates at 2.4 to 2.485 GHz... depending on the version used. If you're thinking of trying to intercept bluetooth signals... you'll have a hard time doing it ! Bluetooth uses 256 bit encryption, and digital signature technology to 'pair' itself between devices. Additionally - the maximum current range is just 800 feet.
In a Bluetooth piconet one master can communicate up to 7 active slaves, there can be some other up to 248 devices which are in sleep mode (may participate to communication actively when another active device goes into sleep mode). In Bluetooth scatternets (interconnected piconets) number of devices are not limited. Some slaves used as a bridge by participating two or more piconets. One of the most advanced topology defined for Bluetooth scatternets is Cube Connected Cycles architecture.
WIFI and Bluetooth are both wireless communication protocols. WIFI is usually used to allow laptops to connect to the internet via a WIFI hotspot or to allow two devices in a home network to communicate without stringing wires, and has a maximum range of about 100 meters. Bluetooth is usually used to connect two devices that are within a few feet of each other, such as a headset and a cell phone.
