Toshiba has added the new mesh protocol capability to its Bluetooth Low Energy 4.2 chips and designed a separate front end to give more range for nodes in the Internet of Things (IoT).
Toshiba says the combination of the new mesh protocol and its existing software for BLE 4.2 (rather than Bluetooth ) gives a link budget over 100 dB with a new design of external PA and LNA, This provides a range of over 300m open-air range at low-power transmit and receive power levels. The current second generation devices such as the TC35678FSG-002 have a current consumption of 3.3 mA in Tx mode and 3.3 mA in Rx mode.
"As a Bluetooth SIG founder and current board member, Toshiba is excited to be among the first to support the organization's push to increase the effective range and robustness of Bluetooth through the introduction of a highly reliable mesh network," said Deepak Prakash, senior director at Toshiba America Electronic Components, "This standards-based approach means that new untapped markets, such as industrial and commercial, can now use ever-present Bluetooth cell phones or tablets to easily control and monitor their systems."
