How far does Bluetooth Low Energy reach?
Range is about the same for both classic and low energy. Technically the max range is about 300 feet or 100 meters, but that’s very generous and assumes a powerful radio. In reality, you will find over 10 or 20 meters can be challenging.. about 2 Mbps max for Bluetooth Classic and less than a Mbps for BLE.
What is NFC range?
approximately 10 centimeters
NFC is intended to be used as an access key to contents and for services such as cashless payment, ticketing and access control. NFC operates in a frequency range centered on 13.56 MHz and offers a data transmission rate of up to 424 kbit/s within a distance of approximately 10 centimeters.
What is maximum range of Bluetooth?
Bluetooth

How do you increase ble range?
Some of the things you should do to get the most range out of your BLE design include:
- Pick a BLE Chipset with good RF performance, high output power and good sensitivity.
- Design a proper RF circuit with 50 ohm impedance and good RF.
- Avoid noise source and other transmitters.
- Use a good, efficient antenna.
What is the maximum distance Bluetooth can cover?
The range of the Bluetooth® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. NOTE: Not all audio devices are supplied with Bluetooth capability.
How does Bluetooth measure distance?
Beacon technology generally estimates the distance between devices using the received signal strength (RSSI). Localization of Bluetooth devices is done by combining the distance estimate to several beacons, mounted at fixed and known locations, using triangulation with at least 3 anchors.
How far can NFC range?
Bluetooth comparison
| Aspect | NFC | Bluetooth Low Energy |
|---|---|---|
| Range | < 20 cm | ≈50 m |
| Frequency | 13.56 MHz | 2.4–2.5 GHz |
| Bit rate | 424 kbit/s | 1 Mbit/s |
| Set-up time | < 0.1 s | < 0.006 s |
How far can NFC?
approximately four centimeters
Bluetooth and near field communication share several features, both being forms of wireless communication between devices over short distances. NFC is limited to a distance of approximately four centimeters while Bluetooth can reach over thirty feet.
What are the different levels of BLE radio transmit power?
Below are a few reference levels: The transmit power of BLE radios available today usually range between 0 dBm to around 20 dBm, with the majority having an upper bound of 4 dBm or 5 dBm, but a few devices exceed this. As an example, Nordic’s nRF52832 can output +4dBm, while the nRF52840 can output +8dBm.
What is Bluetooth Low Energy (BLE)?
Bluetooth Low Energy (BLE) is a low power variant of the widely known wireless transfer technology Bluetooth and is marketed as Bluetooth Smart. The low power consumption is achieved by changing the data protocol to create low duty cycle transmissions.
What is the limit of radio sensitivity for BLE?
For BLE, a standard Packet Error Rate (PER) of 30.8\% with 1500 packets is used as the reference for measuring sensitivity. Meaning, a packet signal level which causes us to lose 30.8\% of the packets will be defined as the limit of radio sensitivity.
What is the difference between BLE and Wi-Fi?
WiFi on the other hand consumes a lot more power than ZigBee and BLE and is used for more heavy duty applications due to its high transfer rate. On a uniformly scaled application, the power consumption of BLE, ZigBee and WiFi were respectively 72 microwatts, 90 microwatts and 0.2 Watt.
