Summary of TRANSFERFI LAUNCHES WIRELESS POWER NETWORK FOR LIGHTNING UP SENSORS UP TO 55 METERS AWAY
TransferFi Pte developed the TFi wireless power network (TFi WPN) to wirelessly power and communicate with sensors up to 55 meters away, targeting building and factory automation to reduce cabling. The TFi Gateway Max Turin-1 supports up to 32 TFi Sense nodes via multichannel beamforming (16 channels) and connects to Modbus, BACnet, and web services. The TFi Sense Turin-1 node (Arm Cortex-M4) includes accelerometer, microphone, temperature, pressure, humidity, TVOC sensors, AES-128 encryption, and transmits up to 5 Hz, operating primarily in 860–940 MHz.
Parts used in the TFi wireless power network (TFi WPN):
- TFi Gateway Max Turin-1
- TFi Sense Turin-1 sensor node
- Arm Cortex-M4 microcontroller (inside TFi Sense Turin-1)
- 3-axis accelerometer (on TFi Sense Turin-1)
- Microphone (on TFi Sense Turin-1)
- Temperature sensor (on TFi Sense Turin-1)
- Pressure sensor (on TFi Sense Turin-1)
- Humidity sensor (on TFi Sense Turin-1)
- TVOC sensor (on TFi Sense Turin-1)
- Multichannel beamforming capability (gateway feature)
- Proprietary encryption and AES-128
For a while now, we have witnessed the use of wireless charging, by placing a phone or other devices that support wireless charging on a charging pad. Energous is one of the companies that started promoting their near-field, mid-field, and far-field wireless charging solutions, with far-field meaning within a room. But so far, they only have released near-field devkits and products.
However, Singapore based TransferFi Pte has developed its own wireless charging solution called the TranferFi wireless power network (TFi WPN), aimed at powering sensors up to 55 meters away, and specifically aimed at building and factory automation to enable companies to save on installation and cabling costs.
The TFi WPN functions with a gateway powering up and receiving data from sensors wirelessly, having a range of up to 55 meters. The TFi Gateway Max Turin-1 has a range of up to 32 TFi Sense devices through multichannel beamforming, offering support for up to 16 channels and can be connected to Modbus, BACnet & Web services. TFi Sense Turin-1’s sensor node is powered by a secret Arm Cortex-M4 microcontroller, and it enables a 3-axis accelerometer, a microphone, temperature, pressure, humidity & TVOC (Total Volatile Organic Compounds) sensors. It also further equipped with proprietary encryption & AES-128, and transmit at up to 5 Hz.
The TFi Sense Turin-1 is optimized to perform within the 860MHz – 940MHz frequency ranges. However, TransferFi can also offer the solution in the 2.4GHz – 5.8GHz bands on request. A representative of TransferFi Pte explains:
