APPENDIX I: GLOSSARY
Bluetooth Low Energy (BLE):
A wireless technology designed to connect an individual person’s devices.
Ferrous:
A material containing Iron. Materials containing iron in the vicinity of a PlacePod can interfere
with the calibration of the device.
Gateway:
LPWAN equipment that receives wireless signals from remote devices (such as parking sen-
sors) using LoRa bandwidth, and then relays these signals to a network service using a different commu-
nications protocol.
LoRaWAN™:
A protocol, defined by the LoRa Alliance, specifying how devices (such as parking sensors)
communicate with LPWAN gateways.
LoRa:
A low-power consumption, long-range technology for wireless data communication, utilizing unli-
censed sub-1GHz bandwidths. The bandwidth utilized varies by region (915 MHz in North America, 868
MHz in Europe). PlacePod communicates with gateways using LoRa bandwidths.
LPWAN:
A Low Power Wide Area Network, utilizing wireless communications to allow battery powered
devices (such as parking sensors) to communicate.
Network:
Two or more devices that communicate with each other. The internet is a very large network
including every device connected to the internet, but a router connecting a computer and a printer is
also a network.
Provisioning:
The process of identifying a device and incorporating it into a network so that it can be
utilized together with the software managing the network.
RSSI:
Received Signal Strength Indicator (RSSI) is a measure of the power level at a receiving device from
a sending device. This power is often measured in dBm, and the higher the power, the stronger the sig-
nal.
SNR:
Signal to Noise Ratio (SNR) is the ratio of the power of a particular signal to the background noise
associated with that signal.
