Overview of the Shopping Mall and Supermarket IoT Solution - Indoor Navigation

Scenario Overview

In large public places such as shopping malls with large areas and complicated environments, it is difficult for customers to find shops or parked cars.

Huawei provides an intelligent indoor navigation solution that allows customers to quickly find shops or parked cars following instructions of a mobile app.

This solution is applicable not only to shopping malls but also to airports, large exhibition centers, and large libraries.

Solution Benefits

This solution brings the following benefits:

Customers can quickly find shops or parked cars using a mobile app, improving customer satisfaction with shopping malls and promoting customers' buying intention.
A WLAN can be reused as an intelligent indoor navigation IoT network to achieve network integration, reducing network deployment and maintenance costs and helping administrators centrally manage the network.

Network Architecture

As shown in Figure 1, the network architecture of the intelligent indoor navigation IoT solution consists of the terminal layer, access layer, network layer, and application layer.

Device	Function	Vendor
AP	Provides wireless network coverage for mobile phones. Scans BLE broadcast frames to obtain BLE device information, and reports the information to an AC. An AP also functions as a BLE device to send BLE broadcast frames. Sends Bluetooth terminal location packets to the AC or location server.	Huawei Only the AP4050DN-E can be used.
AC	Manages APs, delivers configurations to them, and works together with them.	Huawei
Switch	It is used to build a networking structure and forward packet data on the network.	Huawei
BLE device	Periodically sends BLE broadcast frames to provide Beacon signals for Bluetooth terminals such as mobile phones and tablets. Different from the built-in Bluetooth module of an AP, a BLE device is independently deployed.	Lanke Xuntong Technology
Mobile app	Collects BLE device information and RSSIs, collects map information from the location server, and computes and displays BLE device locations. The mobile app is installed on mobile phones or tablets.	EtoneSystem
App server	Obtains map information and BLE device location information from the location server, and sends the information to the mobile app.	EtoneSystem
Location server	Functions as a location server that has location map models and BLE device location information configured.	EtoneSystem
