Abstract: Systems and methods are described for sub-band selection for a wireless device during connection. An access node may receive a RACH preamble message from a wireless device. It may be determined that a received signal level associated with the message does not meet a signal level criteria. The wireless device may be instructed to transmit signal information to the access node. A sub-band that comprises a signal level that meets the signal level criteria may be selected. The wireless device may then be instructed to communicate with the access node using the selected sub-band when requesting a connection.
