Panasonic’s PAN1782: The Bluetooth 5.1 Module with Improved Performance and Extended Range for Smart Cities, Industrial Mesh Networks, and Medical Applications

Category articles

Panasonic’s PAN1782 makes use of Bluetooth 5.1 technology and boasts faster symbol rates of 2 Mbit/s when using LE 2M PHY, as well as significantly extended range by using an LE encoded PHY that can reach 500Kb/s or 125 Kb/s respectively. The newly designed channel selection algorithm (CSA#2) significantly improves efficiency when dealing with high interference situations, and LE Advertising enhancements allow much more data to be transferred in instances that do not necessitate connection. Smart Cities Industrial Mesh Networks and Medical Applications. Bluetooth Low Energy (BLE) PHY stands for Physical Layer, the means by which data travels through the air; LE encoded PHY is one such PHY used with BLE that offers much longer distance compared to higher speed LE 2M PHY.
The LE-encoded PHY enables data transmission at 500 or 125 kb/s symbol speeds, offering greater range compared to its faster LE 2M counterpart. This makes it suitable for urban smart cities as well as industrial mesh network environments.

The Channel Selection Algorithm (CSA) is an algorithm utilized in Bluetooth to control frequency channels within the 2.4-5GHz ISM band to prevent interference from other wireless technology and Bluetooth devices. Introduced as part of Bluetooth 5.1, CSA#2 improves efficiency for Bluetooth devices operating in environments with high levels of interference by searching out less-crowded channels that offer better connections without interference or congestion; additionally it allows devices to adapt better to their surroundings and maintain constant connectivity regardless of any additional wireless signal sources nearby.

Type 2 Near Field Communication (NFC-A) is an electronic communication protocol used for short range wireless communications between electronic devices such as smartphones and other electronic gadgets. Part of the Near Field Communication standard, NFC allows contactless information exchange among devices without direct physical contact being necessary.

Type 2 NFC-A uses inductive coupling technology to allow communications between devices. Operating at 13.56 MHz, this communication standard can transmit data at 424 Kbps transmission rates – making it suitable for mobile payments, data transfer and access control applications as well as connecting and pairing Bluetooth devices.

Built upon Nordic’s nRF52833 Bluetooth chip, this module can accurately determine direction using both angle of entry (AOA) and angles of departure (AOD), through Bluetooth. Furthermore, type two near field communications (NFC-A) via PAN1782 enable pairing as well as payment solutions to be easily implemented.

It also boasts an extremely low power consumption – only 4.9 milliamps in TX mode and 4.7 milliamps in RX mode, making this module perfect for standalone use and compatible with Bluetooth Mesh, Thread and Zigbee Mesh protocols.
