marketing, and communicate user benefits more effectively". On the technical side, Bluetooth 5 will quadruple the range by using increased transmit power or coded physical layer, double the speed by using optional half of the symbol time compared to Bluetooth 4.x, and provide an eight-fold increase in data broadcasting capacity by increasing the advertising data length of low energy Bluetooth transmissions compared to Bluetooth 4.x, which could be important for

pattern. These 80 bits are not FEC encoded as usual but they are sent directly to the radio channel. It is followed by a header block ("FEC Block 1") which is always transmitted in S=8 mode. The header block only contains the destination address ("Access Address" / 32 bit) and an encoding flag ("Coding Indicator" / 2 Bit). The Coding Indicator defines the Pattern Mapping used for the following payload block ("FEC Block 2") where S=2 is possible.

transmission power—is achieved at the expense of a lower data being at an eighth with 125 kbit. The old transmission packet format, as it continues to be used in the 1M PHY and 2M PHY modes, has been named "Uncoded" in Bluetooth 5. The intermediate "LE Coded" S=2 mode allows for a 500 kbit data rate in the payload which is both beneficial for shorter latencies as well lower power consumption as the burst time itself is shorter.

can be inferred for most parametrizations. While the discovery latencies of BLE can be approximated by models for purely periodic interval-based protocols, the random delay added to each advertising interval and the three-channel discovery can cause deviations from these predictions, or potentially lead to unbounded latencies for certain parametrizations.

for each input data bit. In mode S=8 there are eight symbols per data bit with a Pattern Mapping P=4 producing contrasting symbol sequences – a 0 bit is encoded as binary 0011 and a 1 bit is encoded as binary 1100. In mode S=2 using P=1 the range doubles approximately, while in mode S=8 using P=4 it does quadruple.

For instance, a temperature sensor server may notify its client every time it takes a measurement. This avoids the need for the client to 1117:

The discovery latency is therefore determined by a probabilistic process and depends on the three parameters (viz., the advertising interval, the scan interval and the scan window). The discovery scheme of BLE adopts a periodic-interval based technique, for which upper bounds on the discovery latency

BLE devices are detected through a procedure based on broadcasting advertising packets. This is done using 3 separate channels (frequencies), in order to reduce interference. The advertising device sends a packet on at least one of these three channels, with a repetition period called the advertising

The traditional transmission of 1 Mbit in the Bluetooth Basic Rate was renamed 1M PHY in Bluetooth 5. The new mode at a doubled symbol speed was introduced as the 2M PHY. In Bluetooth Low Energy every transmission starts on the 1M PHY leaving it to the application to initiate a switch to the 2M

Bluetooth 5 will increase the data length of this advertising packet. The length of this packet in Bluetooth 4.x was 31 bytes

Bluetooth 5 has introduced two new modes with lower data rate. The symbol rate of the new "Coded PHY" is the same as the Base Rate 1M PHY but in mode S=2 there are two symbols transmitted per data bit. In mode S=2 only a simple Pattern Mapping P=1 is used which simply produces the same stuffing bit

The Bluetooth SIG officially unveiled Bluetooth 5 on 16 June 2016 during a media event in London. One change on the marketing side is that the point number was dropped, so it is now just called Bluetooth 5 (and not Bluetooth 5.0 or 5.0 LE like for Bluetooth 4.0). This decision was made to "simplify

The new packet format of Bluetooth 5 allows transmitting from 2 up to 256 bytes as the payload in a single burst. This is a lot more than the maximum of 31 bytes in Bluetooth 4. Along with reach measurements this should allow for localisation functions. As a whole the quadrupled range—at the same

The "LE Coded" transmissions have not only changed the error correction scheme but it uses a fundamentally new packet format. Each "LE Coded" burst consists of three blocks. The switch block ("extended preamble") is transmitted on the LE 1M PHY but it only consists of 10 times a binary '00111100'
