Jeeva Wireless works in the space of Passive Wi-Fi technology, allowing Wi-Fi connectivity at 10,000x less power than conventional solutions and enabling Wi-Fi access to even the most power-constrained IoT and wireless sensing devices. For pennies and tiny amount of power, Jeeva Wireless enables devices that can send data throughout a building using a new chip developed by the firm that uses reflected radio signals to efficiently transmit data over great distances: technique called long-range backscatter to communicate with other devices. Instead of creating signals from scratch, the chip is able selectively to reflect radio waves that are already passing through space to create a new signal. Jeeva personnel have built out several prototype devices using the technology, including a skin patch and a connected contact lens. Test undertaken by Jeeva have shown devices are able to create their signals when theyre as far as 475 meters from a radio frequency source, and send a signal just as far again at that distance from the source. When the chip is placed next to the radio frequency source, it can send data as far as 1.75 miles. For a more real-world example, the team also says it can send data through a 41-room office or three-story house. These chips, which are predicted to cost about ten cents each to make at mass-production scale, also use up to 1,000 times less power than other wireless data transmission systems such as Wi-Fi. That means that devices rather than requiring a battery could make use of the radio frequency power scavenging technology, also developed firm's principals.
