SAN JOSE, CA, June 25, 2018 -Today, Cassia Networks, an Internet of Things (IoT) connectivity company specializing in long-range Bluetooth patent technology, multi-connectivity Bluetooth Routers and systems, announced adding to its significant intellectual property portfolio with the recent award of U.S. Patent No. 9,960,834, entitled “Methods, Devices and Systems for Increasing Wireless Communication Range” as noted by the US Patent Office.
The U.S. Patent No. 9,960,834 is one-in-a-series of complementary Cassia networks Bluetooth patent awards extending Bluetooth range. Cassia’s previous long-range Bluetooth patent, No. 9,769,594, focused on “smart antenna” capabilities.
The new Patent No. 9,960,834, the next part of a long-range Bluetooth capability, specifies sensitivity gains and filtering capabilities occurring in a Bluetooth router’s front-end hardware circuitry located between the router’s antenna and Bluetooth chip. Because of this receiving and transmitting sensitivity gains and filtering, range is extended between the Bluetooth end device and the Cassia Networks Bluetooth router.
Bluetooth patent connectivity at a 1,000 feet range
The Bluetooth patent describes a method of extending the communication range from a Cassia Bluetooth Router to a Bluetooth Low Energy end device to 1000-feet or more. Importantly, this range extension occurs without increasing transmission power, or using Bluetooth 5. Also, existing Bluetooth end devices do not require physical changes, nor are there decreases in data through-put. “This Bluetooth patent increases global commercial opportunities for Cassia Networks and, more generally, adds to the use cases for Bluetooth IoT,” highlighted Felix Zhao, CEO, Cassia Networks.
Range Extension: Retaining Bluetooth low-power advantages, enhancing Mesh
Bluetooth wireless range extension is typically pursued by increasing transmission power or antenna gain on both side of a radio frequency (RF) transmission, or by connecting sensors in a “mesh” topology. However, these approaches to range extension diminish the fundamental design advantages of Bluetooth, including: low power, data through-put capacity, and low-cost end devices.
Instead, patent U.S. Patent No. 9,960,834 describes an exemplary Bluetooth router configuration, where neither increased transmission power from a Bluetooth end-device, nor a trade-off between power consumption or data through-put (as in Bluetooth Mesh) is required to increase range. Moreover, if Bluetooth 5 is used, then the Bluetooth patent technology significantly extends the Bluetooth 5 range. Additionally, a Cassia router is complementary to a Mesh topology, because it acts as a long-range Mesh gateway, and retains Bluetooth’s low power advantage within Mesh.
Connecting with Cassia: Bluetooth IoT emerging
“In addition to solving the one-to-one Bluetooth limitation with one-to-many Bluetooth connections, the long-range Bluetooth capability enables new categories of Bluetooth IoT use cases,” said Zhao, “As a result of this new connectivity option, there are increasing enterprise Bluetooth IoT use cases ‘Connecting with Cassia’.”
