The Difference Between GPS, LBS, Wi-Fi, iBeacon Positioning

Table of Contents

1.GPS Positioning

The Global Positioning System (GPS) is a high-precision radio navigation positioning system based on artificial earth satellites. It can provide accurate geographic location, vehicle speed and Precise time information. GPS has attracted many users with its high precision, all-weather, global coverage, convenience and flexibility.

GPS is a new generation of satellite navigation and positioning system that has been developed by the United States since the 1970s and was fully completed in 1994.

GPS Working Principle: The basic principle of GPS navigation system is to measure the distance between the known position of the satellite and the user's receiver, and then integrate the data of multiple satellites to know the specific position of the receiver.

2.LBS Positioning

The Location Based Service (LBS) is generally used for mobile phone users. It is a location-based service that obtains mobile terminal users through telecommunications, mobile operators' radio communication networks (such as GSM network, CDMA network) or external positioning methods (such as GPS). With the support of GIS (Geographic Information System) platform, it provides users with a value-added service of corresponding services.

LBS Working Principle: The mobile phone registers the SIM card, and through the known base station location and the signal difference between the Bluetooth module and different base stations, the location of the mobile phone can be obtained through a specific algorithm.

3.Wi-Fi Real-Time Positioning

Wi-Fi real-time positioning is a new technology that uses the existing wireless network, with Wi-Fi module and related mobile terminal equipment such as Wi-Fi mobile phone, PDA, laptop, etc., combined with the corresponding positioning algorithm, to determine the location of relevant people and items.

Wi-Fi Real-Time Positioning Working Principle: Wi-Fi technology is mainly used for indoor positioning. Same as LBS, each wireless module and AP has a globally unique MAC address. When the Wi-Fi is turned on, the device can scan and collect the surrounding AP signals, whether it is encrypted or not, whether it is connected or not, when the signal strength is not enough to be displayed in the wireless list, it can obtain the MAC address broadcast by the AP. Then the device sends the AP data to the location server, and the server retrieves the geographic location of each AP, combines the strength of the signal, calculates the geographic location of the device, and returns it to the user equipment.

4.iBeacon Positioning

iBeacon is a new function equipped with the OS (iOS7) for mobile devices released by Apple in September 2013.

iBeacon Positioning Working Principle: By using Bluetooth low energy technology, the iBeacon base station can create a signal area, and when the device enters the area, the corresponding application will prompt the user whether to connect to the signal network. With small wireless sensors that can be placed in any object and Bluetooth Low Energy technology, users can use the iPhone to transmit data.

For example, if you walk into a store in a large shopping mall with an iPhone 5s (running iOS 7 and supporting iBeacon), it also means that you have entered the iBeacon signal area of the store. The iBeacon base station can then transmit various information to your iPhone, such as coupons or in-store navigation information, and even provide personalized product recommendations when you walk to certain counters. In other words, within the information area of the iBeacon base station, users can obtain personalized micro-location information and notifications through their smartphones.
