Bluetooth Range Exceeds 1km
EZURiO says that it has launched a new breed of Bluetooth wireless module which exceeds one kilometre range in line of sight applications with a compact on-board antenna. The module has been designed specifically for customers with embedded and M2M applications where range and performance are critical.
EZURiO's new module is the size of a postage stamp, includes an omni-directional antenna and consumes less than 700mW when transmitting at full power.
"It has long been a cause of frustration that so many commentators and engineers have assumed that Bluetooth is just a short range technology", said Nick Hunn, CTO of EZURiO. "Simply because some applications, such as headsets, deliberately restrain their range, Bluetooth is often considered to have limited application."
Although a range of 1,000 metres may appear to greatly exceed a customer's application needs, it translates to a highly tolerant and robust connection when used inside a building. Even with dynamically changing environment such as offices, restaurants or factory floors, the connection remains stable. "Many of the usages of Bluetooth are within buildings or constrained sites, where the environment changes rapidly causing attenuation and reflection of the radio signal", said Chris Shannon - CEO of EZURiO. "The extra range we can offer helps eliminate black spots in these environments and is one of the key reasons that integrators are coming to us to solve their wireless connectivity problems."
EZURiO's new high power Bluetooth BISM II PA module is pin and footprint compatible with their existing range of modules."
