1. A method for maintaining wireless connectivity between a mobile controller and a remote controller, the method comprising:
providing a wireless adaptor operatively coupled between the mobile controller and two WiFi access points that are operatively coupled to the remote controller, the wireless adaptor having a single wireless transmitter and configured to have a timing-multiplexed operational mode,
wherein wireless connectivity may be maintained between the mobile controller and the remote controller on both
a first channel to a first WiFi access point of the two WiFi access points, and
a second channel to a second WiFi access point of the two WiFi access points, such that data transmission between the mobile controller and the remote controller is switched between the first channel and the second channel based at least in part upon data transmission timing gaps associated with a regulated time-based protocol that is operated by the wireless adaptor and the first and second WiFi access points, and
wherein data is alternated in bit packets based upon a bit packet size through the single wireless transmitter from both the first channel and the second channel; and
operating the wireless adaptor to automatically:
scan to find a first available WiFi access point and a second available WiFi access point and determine a signal strength of the first available WiFi access point and the second available WiFi access point;
connect with a primary WiFi access point using the first channel, the primary WiFi access point being the first available WiFi access point or the second available WiFi access point having a strongest determined signal strength;
while retaining wireless connectivity with the remote controller through the first channel, continue scanning using the second channel to find an alternative WiFi access point and determine a signal strength of the alternative WiFi access point;
compare the signal strength of the primary WiFi access point connected through the first channel with the signal strength of the alternative WiFi access point available through the second channel; and
maintain wireless connectivity between the mobile controller and the remote controller through a respective channel of the first and second channels associated with one of the primary WiFi access point and the alternative WiFi access point that has the strongest signal strength.
