Abstract
Systems and methods for a scalable architecture for radio device and systems are disclosed. This architecture employs a scalable bandwidth to deliver higher data rates and transmission ranges to devices that need them, while still delivering lower power solutions for devices which utilize a smaller bandwidth. These systems and methods may divide the available frequency spectrum into a set of fundamental sub-bands. Different devices may use various multiples of these sub-bands depending on their needs. Devices employing this architecture are also capable of interoperation with one another regardless of the bandwidth they utilize. A device may scan through each sub-band within which the device intends to operate, searching for a common beacon transmitted by other devices utilizing the sub-band. If a beacon is found the device can choose to interoperate with the other device or, alternatively, continue scanning the sub-bands until an unused sub-band is found.
