LoRaWAN is a Low Power Wide Area Network (LPWAN) specification that targets key requirements of Internet of Things (IoT) such as such as secure bi-directional communication, mobility and localisation services.
It provides the ability to operate among smart things without any complex installations and gives freedom to the user, developer and businesses, allowing the straighten of Internet of Things (IoT).
NBIoT is a narrowband RF communication technology, specially designed for the Internet of Things (IoT). It connects devices more easily and efficiently on already established mobile networks, and handles small amounts of infrequent 2-way data, securely and reliably. The special attention of this standard is on very low power consumption, excellent penetration coverage and lower components costs, deployed in GSM and LTE regulated frequencies.
RADIO FREQUENCY (RF)
Radio Frequency is a low power, wide area technology standard published by 3GPP. It also supports Internet of Things (IoT) through lower device complexity and extended coverage, while allowing the reuse of the RF installed base. It is supported by all major mobile equipment , chipset and module manufacturers. RF is compatible with 2G, 3G and 4G mobile networks and benefit from all the security and privacy features of carrier-grade networks.
The RS485 is the most complete and technologically advanced system tailored to the needs and requirements of road tunnel lighting control. It captures the luminance at the tunnel portal to adjust the various zones according to Standards. Alignment monitoring of the photometer for more precise lumens reading. The RS485 also measures the level of illuminance within the tunnel bore to ensure the illumination levels are maintained between cleaning.
The network controller acts as master unit that controls each lamp’s local unit (LPC) according to their location, the required level, or commands from the operator. The local product controller installed in the luminaires, the LPC and monitors the driver. Additionally to controlling on-off and dimming the lamps according to the required light level, the LPC computes the hours of use for each luminaire, and performs a diagnostic on each and render systematic reports to the System.
