Bluetooth has no single dependable range: the Bluetooth SIG says reliable effective distance can be less than a meter or more than a kilometer, depending on the devices and conditions. That broad technology-wide span is not a promise for your phone, headphones, speaker, keyboard, or any other specific pair.
Why Bluetooth range has no single answer
Bluetooth SIG describes a wide range of possible reliable connections, from less than one meter to more than one kilometer. The usable distance is determined by both endpoints and the radio path between them—not by the Bluetooth logo or version number alone. Bluetooth SIG’s range guidance explains the technology-wide range; it is not a consumer-device range guarantee.

For example, Bose says selected Bose Bluetooth 5.3 products have an effective range of up to 33 feet. That is a claim for those products, not a standard distance for every Bluetooth device. Bose’s range information does not make its figure interchangeable with other products’ claims.

Transmit power and receiver sensitivity
Transmit power affects how strongly a device sends a signal; receiver sensitivity is how weak a signal it can still decode under specified conditions. Both matter, and the weaker endpoint can limit the link. Bluetooth SIG describes supported Low Energy (LE) transmit levels from −20 dBm (0.01 mW) to +20 dBm (100 mW). Those are supported levels, not a claim that every device transmits at the maximum. Higher power can use more energy, is constrained by device design and local regulations, and can saturate a nearby receiver.

The Bluetooth Core Specification 6.2 sets PHY-dependent LE receiver sensitivity requirements: no worse than −70 dBm for uncoded PHYs, −75 dBm for LE Coded S=2, and −82 dBm for LE Coded S=8. A more negative dBm value represents a weaker signal. These specification requirements help explain radio performance; they do not predict the range of a specific product pair. Bluetooth Core Specification 6.2
Radio mode, antenna and data rate
Bluetooth LE PHYs trade off data rate and robustness. Antenna design, size, efficiency and placement also affect how well each endpoint sends and receives. Bluetooth SIG says antenna gain in Bluetooth devices is typically in the range of −10 dBi to +10 dBi. A device’s Bluetooth version, by itself, does not tell you its antenna performance, supported PHYs or practical range.

Walls, materials and interference
Distance reduces signal strength, and obstacles can weaken or scatter the signal. Bluetooth SIG identifies walls, windows, wood, metal and concrete as possible attenuators. The actual effect depends on the material, construction and geometry; dense metal or concrete can be especially obstructive. Bluetooth also shares the 2.4 GHz band with other radio uses, so nearby interference and the placement of a computer’s Bluetooth adapter can affect stability. Plugable’s computer troubleshooting guidance recommends reducing interference and improving adapter placement.
How to read published Bluetooth distance claims
Distance figures are meaningful only alongside the product, endpoints and stated test conditions. These manufacturer examples describe different situations and should not be averaged into a “typical” Bluetooth range.

Bluetooth SIG’s Range Estimator also uses separate propagation assumptions for home/office and industrial environments. Its home/office model is based on measurements up to 45 m and does not estimate beyond that distance; its industrial model is based on measurements up to 140 m and likewise does not estimate beyond it. These are model limits, not guaranteed distances for Bluetooth devices. Bluetooth SIG Range Estimator

Does Bluetooth LE Coded reach four times farther?
LE Coded PHY uses forward error correction to help a receiver recover data when the signal is weak, without increasing transmit power. The trade-off is a lower data rate: Bluetooth SIG lists 500 kb/s for S=2 and 125 kb/s for S=8, compared with 1 Mb/s for LE 1M. Its reliability paper describes approximately twice the range for S=2 and four times for S=8 relative to LE 1M. These are approximate PHY-level comparisons, not fixed distances for a consumer product. Both devices and the connection configuration must support the mode.

What to try when Bluetooth cuts out
- Move the devices closer. If the connection stabilizes, distance or signal loss is likely part of the problem.
- Improve the radio path. Where practical, establish clearer line of sight and move devices away from dense metal or concrete obstructions.
- Adjust computer placement. Reposition the Bluetooth adapter and reduce nearby radio interference, then check whether the link becomes more stable.
- Check both devices’ specifications. Look for supported Bluetooth modes and PHYs, receiver or antenna details, and the conditions behind any advertised distance. A higher Bluetooth version number alone does not settle the question.
Will a Bluetooth range extender work?
Only rely on an extender when its manufacturer says it supports the exact devices or system you have. Lennox documents a wireless extender for its BLE sensor-to-S40 system; that example does not establish that a generic repeater will extend a phone, headphones or arbitrary peripherals. The Lennox S40 documentation describes the system-specific use.
