Retail Store Connectivity Solution

1. Solution Overview

1.1 Project Background

As chain retailers expand nationwide, network reliability directly impacts core in-store operations — POS transactions, video surveillance, and real-time data synchronization. A single-link wired WAN failure can disrupt checkout experiences and cause revenue loss. This solution addresses two critical challenges: keeping every retail store always online through automatic WAN + 5G Cellular failover, and enabling headquarters IT teams to remotely manage hundreds of stores from a single platform.

1.2 Objectives

  • Seamless WAN + 5G Cellular failover with zero business interruption
  • Plug-and-play deployment — store staff can install without on-site engineers
  • Centralized remote management via InCloud Manager for real-time visibility
  • Secure data transmission with VPN encryption and multi-layer firewall

1.3 Use Cases

  • Chain retail stores / convenience stores / supermarkets
  • Franchised and directly-operated store network standardization
  • Distributed store centralized O&M management

2. Requirements Analysis

2.1 Current Device Landscape

Item Description
Device Types POS terminals, barcode scanners, payment systems, digital signage, IP cameras, staff/customer devices
Interfaces Ethernet, Wi-Fi, 4G/5G
Deployment Indoor retail stores, geographically distributed
Scale Large-scale (hundreds to thousands of stores)

2.2 Core Requirements

  1. Always-on Connectivity — Auto-failover to 5G Cellular when wired WAN degrades or fails; auto-failback when restored
  2. Easy Deployment — Store staff self-installation; zero-touch provisioning via cloud
  3. Centralized Management — HQ IT monitors all stores in real time; remote troubleshooting without site visits
  4. Data Security — VPN tunnels and firewall policies to protect transaction data
  5. High-Performance Wi-Fi — Stable wireless access for staff terminals and customer devices

3. Architecture Design

3.1 Four-Layer Architecture

Layer Components
Perception POS terminals, barcode scanners, payment systems, digital signage, IP cameras, staff/customer devices
Network FWA02 (Wired WAN primary + 5G Cellular backup, Wi-Fi 6)
Platform InCloud Manager SaaS, HQ Data Center / Operations Center
Application Transaction processing, product info sync, video surveillance, guest Wi-Fi, centralized O&M

Failover Logic: FWA02 continuously monitors WAN link quality (latency, jitter, packet loss). Upon detecting degradation or failure, it automatically switches to 5G Cellular. Once the wired link recovers, it fails back automatically — no manual intervention required.

4. Network & Access Solution

4.1 Connectivity Design

Primary Link — Wired WAN: 2.5 GbE broadband connection delivering high bandwidth and low latency for all daily store operations.

Backup Link — 5G Cellular: 5G SA/NSA with up to 4.76 Gbps downlink / 1.25 Gbps uplink, with automatic fallback to 4G LTE Cat 19 (1.6 Gbps DL). Dual Nano SIM + eSIM support enables flexible carrier switching for maximum backup reliability.

4.2 FWA02 Device Specifications
