Bluetooth 5 arrived on the market just over a year ago. It was announced by the executive director of Bluetooth SIG that the new device would revolutionize the IoT. The latest version of Bluetooth 5 has many advantages over Bluetooth 4.3 technology such as longer range, faster speed and extended support for connectionless services. According to market surveys, by 2020 Bluetooth will be used in more than a third of all installed IOT devices. The typical IoT architecture consists primarily of physical, communication, software, and application layers. Bluetooth serves as a communication protocol that allows devices to communicate with each other wirelessly. Say no to plagiarism.

This also leads to doubling the data transfer between two devices and studies show that the current consumption is also very low compared to previous versions of Bluetooth devices. This improves the time spent in low-power sleep mode in IoT devices. The great thing is that Bluetooth 5 devices have backward compatibility which provides support for Bluetooth 4 devices to work well in IOT. Bluetooth 5 has four times the coverage area of ​​Bluetooth 4 devices. This means it can cover an entire home or building, or it can be used in outdoor or commercial applications, and IoT becomes a reality for those areas with the new inventions of Bluetooth 5. In addition to the 2M PHY, Bluetooth 5 contains two additional PHY options called LE encoded PHYs. This code uses a slightly different packet format and increases Rx sensitivity which leads to improved coverage range. LE Coded PHY has forward error correction (FEC) and a Pattern Mapper. It applies FEC methodology to correct bit errors upon packet reception and after applying a pattern mapper to the packet to improve communications efficiency. Bluetooth 5 is defined as +20dBm, while Bluetooth 4 must be +10dBm. This increases the Tx power by 10x and should have an impact on the coverage range. An advertising-related improvement (beaconing) is the advertising datasets feature, which allows a single Bluetooth 5 device to send multiple individual advertising datasets with unique intervals and announcements. data. The new Bluetooth can also determine a scan request made by a remote device and report it at the application level. The next improvement is that the three advertising channels used in Bluetooth 4 are present in Bluetooth 5 for backward compatibility, but Bluetooth 5 devices can use the remaining data channels as secondary advertising channels to transmit more data, improving channel capacity . . Another improvement is that Bluetooth 5 introduces periodic advertising. It allows the transmitter to periodically send changed beaconing data and at a fixed interval the receivers can listen to it.

Bluetooth 5-enabled phones are expected to hit the market during 2017 and will take some time to mature on the IoT. More and more companies are already building chips that support it
