The TIC environmental event sensor is a nickel-sized, ultra-thin circuit assembly, containing an extremely compact array of both environmental sensors and physical sensors, along with local and wireless access to all the sensor data, including BTLE & LoRa, as well as an electronic ink display for limited field access to sensor events in real time. The TIC is designed to capture changes in the sensor data in real time, and then log it for future examination. The most recent change will remain on the device’s display. The changes can then be transmitted to a smart phone or tablet via BTLE, networked as an asset via LoRa, or locally scrolled at the device. The TIC is Ideal for tracking any variations in the surrounding conditions of an asset’s travel, storage, or use.

Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus, an encoding section encodes and outputs transmitting data to a bit converting section, and the bit converting section converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section. The modulating section modulates the bit string inputted from the bit converting section by using a single modulation mapper and a plurality of data symbols are generated.
