Bluetooth Low Energy Long Range

Bluetooth low energy technology operates in the same spectrum range the 2 400 2 4835 ghz ism band as classic bluetooth technology but uses a different set of channels.

Bluetooth low energy long range.

The longer answer to the question about the range of bluetooth technology is it depends. We demystify the long range capabilities of bluetooth low energy with a range test you can repeat for yourself. Instead of the classic bluetooth seventy nine 1 mhz channels bluetooth low energy has forty 2 mhz channels. Use the cc2590 range extender to increase output power and improve sensitivity and thus achieve much longer range.

Bluetooth low energy has a much longer range than is popularly believed to be the case even at version 4. Kw39 38 37 bluetooth low energy long range field tests line of sight field range tests are performed on the nxp kw39 38 37 bluetooth low energy 5 0 long range microcontroller. The first two phys are primarily used for streaming data at close range. Unlike other wireless technologies bluetooth technology is designed to support a wide range of achievable ranges between two devices providing developers tremendous flexibility to create wireless solutions that best meet the needs of their target use case.

By rick desmaris gunnar pope graham clarke. The le coded phy allows range to be quadrupled approximately compared. Introduction bluetooth low energy was designed to provide considerably reduced power consumption and cost while maintaining communication ranges similar to bluetooth classic. Being engineers they want to know what to expect if they use bluetooth low energy also know as ble or bluetooth 4 0 as the wireless technology to send and receive data.

With bluetooth version 5 0 a new long range mode was introduced. But doing this negatively impacted current consumption of your product. For a 1 6 km 1 mile radio link which is achievable with bluetooth low energy long range modulation the antennas would need to be at approximately 7 meters of height 21 ft to avoid the effect of the ground entering the fresnel zone and affecting the measurement. By increasing radio transmit power.

Before the launch of bluetooth 5 there was just one way to increase range in your bluetooth low energy ble product. Here is the scenario and ble range expectations. However that is no longer the case. What determines bluetooth range.

The antenna is installed inside of the block wall building on the second floor. You can now achieve ranges of over 1 kilometer using bluetooth low energy. Tidc bluetooth low energy long range is a bluetooth smart reference design for long range applications.
