Toshiba's line-up of Bluetooth Low Energy (BLE) products has started supporting the new Bluetooth Mesh standard.

Ratified and launched by the Bluetooth Special Interest Group (SIG), the combination of Bluetooth Mesh and Toshiba’s application software enable the BLE products to simultaneously increase communication range, reliability and obstacle penetration capability while also increasing battery life.

In a related effort to increase communication range and signal strength for Bluetooth, Toshiba has introduced new Bluetooth Low Energy system solutions capable of achieving a link budget of over 100dB using an external PA and LNA. Toshiba has demonstrated these system solutions providing well over 300m open-air range at low-power transmit and receive power levels. When combined with support for Bluetooth Mesh, Toshiba’s Bluetooth products offer a comprehensive solution for extended-range Bluetooth 4.2.

Support for the new Bluetooth Mesh standard enables Toshiba's BLE products to privately and securely traverse a mesh network rather than requiring a point-to-point connection between devices. This increases the range and reliability of BLE communication without increasing power requirements.

Previously, increasing the effective BLE communication range or sending a signal through many walls required higher power transmissions that would have a negative impact on battery life. These high-powered transmissions were typically the primary technique used to address issues such as radio interference in a factory environment or the transmission of signals through thick concrete walls. This approach had severe limitations and has proven to be ineffective for power-constrained battery operated devices as well as in unfriendly RF environments. By creating a robust mesh network, Toshiba said its BLE products can securely and privately relay messages, allowing devices to communicate in places where they previously were unable to.
