Wireless Protocols
We should consider to a combination of options to ensure a stable connection during ASC and FSGP
| Protocol | Range/Coverage |
|---|
| Theoretical | Measured | |
|---|---|---|
| Wi-Fi | 100 m (typical) 3-5 km (long-range & omnidirectional) Direct line-of-sight to the router | > 36.1 Mbps |
10 km
Better non-line-of-sight performance due to a lower frequency of 915 MHz than 2.4 GHz
Pi 3+: 54.6 Mbps (Upload) 42.1 Mbps (Download) | |
| LTE | Verizon has LTE coverage over the FSGP track and most of the roads along the ASC route Direct line-of-sight to the tower |
CAN-Wireless Bridge
> 2 Mbps (Upload) > 5 Mbps (Download) | SIM7600X: > 0.68 Mbps (Upload) > 6.27 Mbps (Download) | ||
| GSM | Carriers are deprecating 2G in favour of 4G. Direct line-of-sight to the tower. | 20 ~ 50 kbps | |
| CAN | = 500 kps |
LTE Coverage
| Location | LTE Coverage |
|---|---|
| Heartland Motorsports Park | All carriers |
| Topeka - Kansas City | All carriers |
| Stage 1 | Verizon and AT&T |
| Stage 2 | Verizon: 90%; poor reception around Whiskey Park |
| Stage 3 | Verizon: 90% |
| Stage 4 | All carriers |
