WiFi Access Point with 3G Module for Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WiFi systems face complexity and limited coverage due to the need for numerous access points and wired connections, which restricts mobility and increases deployment costs, especially in outdoor environments.
Innovation Solution
Integrating a 3G network component into the WiFi access point, allowing it to access the 3G network as a 3G terminal and connect with the AC/BRAS through the 3G Radio Access Network (RAN) and Packet Switch Core Network (PSCN), reducing access complexity and enhancing mobility support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WiFi access points use wired connections to connect with AC/BRAS, then network stability is improved, but device complexity and deployment cost increase
Solution Approach 1:
The access point is designed with dual functionality: it can operate as a WiFi access point for wireless connections while simultaneously functioning as a 3G terminal for mobile network access. This multi-functionality eliminates the need for dedicated wired connections to AC/BRAS, as the 3G capability provides an alternative communication path, thereby reducing network wiring complexity while maintaining network stability through the wireless 3G backhaul.
2Area of stationary object
If multiple access points are deployed to expand coverage, then coverage area is improved, but device complexity and deployment cost increase
Solution Approach 1:
Each access point incorporates 3G terminal functionality, enabling it to independently establish wireless connections with the core network through the 3G network. This eliminates the requirement for complex wired interconnections between multiple access points and the AC/BRAS, allowing for simpler deployment of additional access points to expand coverage area without proportionally increasing system complexity.
3Reliability
If wired connections are used for access point deployment, then connection reliability is improved, but ease of operation deteriorates due to mobility limitations
Solution Approach 1:
The access point system transitions from a static wired connection model to a dynamic wireless connection model utilizing 3G network. The 3G terminal capability enables the access point to move freely within 3G network coverage areas while maintaining reliable wireless connections to the core network, thereby providing mobility support without sacrificing connection reliability.

AI summary
Disclosed are an access method for a WiFi access point, a WiFi access point and a WiFi system, which relate to communications technology. The present application adds to a WiFi system the RAN and PSCN of a 3G network, and adds a 3G module to an AP, so that the AP can serve as a 3G terminal to access the 3G network, thereby connecting the AP and an AC/BRAS through the RAN and PSCN. Because the 3G network has broader coverage, implementing access point access through the 3G network reduces the complexity of an AP accessing the AC/BRAS.
