Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving monitor data from a lighting equipment monitor. A data stream is created based upon the monitor data. A first signal strength of a signal from the access point received at a first antenna is measured. A second signal strength of the signal from the access point received at a second antenna is measured. One or more antennae are selected to transmit the spread data stream based upon the first signal strength and the second signal strength. The data stream is transmitted using the one or more selected antennae.

The method of claim 1, wherein selecting one or more antennae comprises selecting the antenna with the highest signal strength. 5. The method of claim 4, further comprising: monitoring a signal strength of the selected antenna;determining if the signal strength is below a predetermined threshold; and switching to an unselected antenna based upon determining if the signal strength is below the predetermined threshold. 6.

The lighting equipment monitor of claim 12, wherein the one or more processors are further configured to: monitor a signal strength of the selected antenna;determine if the signal strength is below a predetermined threshold; andswitch to an unselected antenna based upon determining if the signal strength is below the predetermined threshold. 15. The lighting equipment monitor of claim 12, wherein the one or more processors are further configured to: determine a light is not functioning properly based upon the monitor data; andinitiate a transmission of the data stream based upon the determination that the light is not functioning properly. 16. The lighting equipment monitor of claim 12, wherein the lighting equipment monitor monitors an obstruction light. 17. The lighting equipment monitor of claim 12, wherein the monitor data comprises data representing a voltage or a current used to power a light. 18. The lighting equipment monitor of claim 12, further comprising a receiver configured to receive, from the access point, a monitor read schedule, wherein receiving the monitor data is based upon the received monitor read schedule. 19. The lighting equipment monitor of claim 12, wherein the randomly selected timing offset is between zero and a spreading factor used to spread the data stream minus one. 20. The lighting equipment monitor of claim 12, wherein the transmitter is further configured to retransmit the spread data stream with a third randomly selected timing offset if an acknowledgement is not received within a predetermined time period.
