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. Instead of the classic Bluetooth 79 1-MHz channels, Bluetooth Low Energy has 40 2-MHz channels. Within a channel, data is transmitted using Gaussian frequency shift modulation, similar to classic Bluet… WebIntroduced in December 2016, the LE 2M PHY doubles the data rate that can be achieved between Bluetooth Low Energy (LE) devices from the original LE 1M PHY. The LE 2M PHY improves data transfer performance and provides greater spectral efficiency for the growing number of IoT devices that consumers are connecting to their smartphones, including ...
WebLE 2M PHY vs LE 1M PHY¶ The LE 2M PHY feature uses the same transmit power as the LE 1M PHY, the only change is in the modulation of data in the PHY. Using the LE 2M PHY, the energy consumption decreases due to higher data modulation at the same output power. The following table lists some of the differences between the two PHYs: WebDec 31, 2024 · PHY is short for Physical, as in the Physical Layer.
