In a wireless communication network, specific portions of the communication may combine directional transmission with omnidirectional reception. In particular, sector-level directional transmission may be established through sector sweeps, followed by antenna training for more directionality. In some embodiments, collisions during the exchange may be reduced by having different network devices use different sub-channels or different time slots. In some embodiments, each network may restrict its network communications to a single sub-channel that is different than the sub-channels used by adjacent networks.
