How IoT Parking System Works with Different Protocols?

In a smart parking system using IoT, various communication interfaces are used to enable connectivity and data exchange between the different components of the system. The two most commonly used protocols are LoRaWAN and BLE, which are used with IoT gateways to bring support to smart parking systems.

How LoRaWAN Parking System Works?

In a smart parking system, LoRaWAN serves as a crucial communication protocol, enabling seamless connectivity and efficient data exchange between various components.

Parking Sensors

LoRaWAN-enabled parking sensors are deployed in individual parking spaces to detect occupancy. These sensors utilize various technologies such as ultrasonic, infrared, or magnetic field sensing to determine the presence of a vehicle. When a vehicle occupies or vacates a parking space, the sensor captures this information.

LoRaWAN Transceivers

The parking sensors are equipped with LoRaWAN transceivers that facilitate wireless communication. These transceivers utilize LoRa modulation, which enables long-range transmission of data while consuming minimal power. The LoRaWAN transceivers within the sensors transmit the occupancy status and other relevant data to nearby LoRaWAN gateways.

LoRaWAN Gateways

Gateways act as intermediaries between the parking sensors and the central server. They receive data from multiple sensors within their range and aggregate the information. LoRaWAN gateways are connected to the internet and employ cellular, Ethernet, or Wi-Fi connections to relay the collected data to the central LoRaWAN server.

DSGW-210B, an exceptional LoRaWAN gateway, is a game-changer for smart parking. With its long-range communication capabilities, it collects data from parking sensors, ensuring real-time parking occupancy updates. The gateway’s compact design, effortless deployment, and robust security features make it an excellent choice, enhancing parking efficiency and elevating the overall user experience.

Central Server

The central server serves as the core component of the smart parking system. It receives the data forwarded by the LoRaWAN gateways and processes it. The LoRaWAN server analyzes the occupancy information, updates the parking status in real-time, and maintains a database of parking availability.

User Interface

The central server interacts with various user interfaces, such as mobile applications, websites, or digital signage. This allows users to access real-time parking information, including available spaces, parking rates, and navigation assistance.

A star-of-stars topology is supported by the LoRaWAN network design. It enables many parking sensors to interface with neighboring gateways, which transfer data to the central server. This decentralized method makes it easier to deploy and maintain parking sensors across a large area.

The long-range communication capabilities of LoRaWAN are ideal for smart parking systems covering large parking lots or distributed parking spaces. Because of the low power consumption of LoRaWAN devices, parking sensors can function on battery power for extended periods of time, reducing maintenance requirements.

Furthermore, the scalability of LoRaWAN allows the system to manage a high number of parking sensors and gateways, making it perfect for handling several parking spaces at the same time. Through data analysis, the centralized server can give real-time parking availability information, enhance parking operations, and provide important insights.

How BLE Parking System Works?

BLE technology, along with BLE beacons, offers several advantages when integrated into a smart parking system. Let’s explore how BLE works in this context:

ble smart parking

BLE Gateway

A BLE beacon gateway in a smart parking system serves as a link between BLE-enabled devices like smartphones and BLE beacons and the central management system. The gateway receives data from BLE beacons installed in parking spaces, collects occupancy information, and communicates it to the central system.

For the best smart parking system, choose the DSGW-030 BLE 5 gateway. It provides easy communication with BLE-enabled devices, such as smartphones and beacons, thanks to its support for BLE 5 technology. This gateway improves the entire parking experience for users by maximizing parking space use and providing real-time parking availability updates.

BLE Beacons

BLE beacons are small, battery-powered devices that periodically transmit signals using the Bluetooth Low Energy protocol. These beacons are strategically placed in individual parking spaces or throughout the parking area.

Mobile Apps

Users can install a mobile application on their smartphones, which scans for nearby BLE beacons and captures their UUIDs. The application utilizes the  RSSI to estimate proximity to the beacons, thereby determining parking space occupancy.

Proximity Detection

When a vehicle equipped with a BLE-enabled device comes within range of a BLE beacon, the beacon’s signal is detected by the device. By measuring the RSSI, the application can determine if the parking space is occupied or vacant.

Real-time Parking Availability

The mobile application collects data from nearby beacons and sends it to a central server. The server processes this information and maintains a real-time parking availability database. Users can access the application to view the availability of parking spaces, making informed parking decisions.

Utilizing the received signal strength and known beacon locations, the mobile application can provide navigation assistance to users. It guides them to the nearest available parking spaces within the parking area, improving the overall user experience.

Integration with Payment Systems

BLE can be integrated with payment systems, allowing users to pay for parking directly through the mobile application. This simplifies the payment process and eliminates the need for physical payment at parking meters or kiosks.

BLE’s low power consumption allows BLE beacons to operate on battery power for extended periods, reducing maintenance requirements and ensuring continuous beacon availability. Furthermore, BLE offers excellent device interoperability, enabling BLE-enabled smartphones and other devices to communicate seamlessly with the beacons. 

Given its short-range communication capabilities, BLE is well-suited for localized smart parking systems, such as parking garages or indoor parking areas. Deploying BLE beacons in each parking space enables accurate detection of vehicle presence, providing real-time parking occupancy information.
