Sub-11GHz proprietary broadband wireless access (BWA) systems are not WiMAX-certified or designed for IEEE 802.16. They include technologies such as IPWireless, Flarion and iBurst. In most cases, they are deployed to provide service providers with quick and easy access to business subscribers or to allow the delivery of broadband data services or fast Internet access to business and residential subscribers. In addition, these systems enable cost-effective network access in remote rural areas. Sub-11GHz proprietary BWA systems provide more than 1 Mbps per subscriber.
