Radios
If intermediate results want to be known at the finish line, then radios are needed. Two types are available: a cellular system, and a LoRa (long-range) mesh radio equipment set. Either has advantages and disadvantages:
Cellular:
| Pros | Cons |
| Needs cellular coverage at each radio control | |
| Internet connection on finish line computer | |
| No distance limit between radio control and finish line computer |
Mesh Radio system:
| Pros | Cons |
| Distance between radio control and finish line limited by terrain, can be overcome with radio relays | |
| Self-contained |
More information about these two radio systems can be read here.
Mesh Radio Transmitter
This device is used at a control location to transmit data whenever a competitor checks in at the control. Not included is either a SPORTident SRR control, or the discontinued BSF-7 RS232 control (if in your possession)
Mesh Radio Receiver base station
This device is the receiver of the O-Store Mesh radio system at the finish line computer
Mesh Radio Relay Radio
This device is a pure relay, which would be placed on hilltop to aid in relaying information from longer distances.
6 dBi Antenna
This antenna is meant for longer distance transmission and can be mounted on a painter's pole (not included). It comes with a 20ft cable to connect to one of the radios.
SPORTident LTE modem Radio
The cellular LTE modem captures the data from a SIAC or SRR control and transmits it to the event center at https://center.sportident.com. Race software can retrieve the data within seconds of the punch occurring.
