Abstract: Systems and methods are described for assigning a mobility parameter to a wireless device. One or more measurement reports may be collected at an access node from the wireless device. A pathloss change for the wireless device may be calculated based on the collected measurement reports. When the calculated pathloss change exceeds a threshold, the wireless device may be instructed to report surplus transmit power at the access node. The reported surplus transmit power may be correlated to preset location environments and a position of the wireless device classified based on the correlation. A mobility parameter may be assigned for the wireless device.

Abstract: Systems and methods are described for assigning operating bands to wireless devices of a wireless network. Registration notifications for a plurality of wireless devices are received at an access node. Each of the plurality of wireless devices are classified as either an indoor wireless device or an outdoor wireless device. The access node instructs wireless devices classified as indoor wireless devices to operate on a first operating band. The access node instructs wireless devices classified as outdoor wireless devices to operate on a second operating band.

Abstract: Systems and methods are described for extending coverage of a wireless device. A handover trigger threshold may be established for a plurality of wireless devices located in a coverage area of an access node. An attachment request may be received at the access node from at least one wireless device having a power class different from a common power class of the plurality of wireless devices. Based on the reported power class, the access node may adjust a handover trigger threshold for the at least one wireless device. The access node may instruct the at least one wireless device to extend its coverage until the adjusted handover trigger threshold is met.
