Apparatus and methods related to acquiring service on mobile computing devices (MCDs) are provided. An MCD can determine whether the MCD is connected to a wireless network. After determining that the MCD is not connected to the wireless network, the MCD can determine a scanning context that includes a mobility attribute and/or a location attribute. Based on the scanning context, the MCD can determine frequencies associated with the wireless network and scanning rates for scanning the frequencies, where each frequency can be associated with a respective scanning rate. The MCD can scan one or more of the frequencies at one or more respective scanning rates for a signal that enables the MCD to attempt connection with the wireless network.

Low power out of service recovery of mobile computing devices

A system and method is disclosed that includes receiving connectivity information from a plurality of client devices connect to a network associated with a plurality of base stations; storing the connectivity information in one or more memories; determining a first location of a first device that desires to connect to a base station associated with the network; identifying a set of candidate bands and channels for connection to the base station based on the first location and the connectivity information; and transmitting the set of candidate bands and channels to the first device.

System and method for improved band-channel scanning and network switching

Systems and methods of hybrid control of a computer network are provided. The system can comprise a controller and a plurality of nodes having an in-band control plane network arranged in a directed acyclic graph routing topology. A first node of the plurality of nodes can be configured to detect a link failure of a first link, the first link being controller-directed. The first node can reverse a second link to a second node from outward-directed to controller-directed such that the first node can communicate with the controller via the second link and the in-band control plane network. The first node can detect a reversal of the second link caused by the second node. The first node can determine that the in-band control plane network is partitioned. The first node can use an out-of-band control plane network to inform the controller that the in-band control plane network is partitioned.
