Enterprise Internet Solutions for Business

Q: What is a 5G enterprise backup solution?

A 5G backup solution provided by Welink Tech is a redundant business continuity architecture that takes over instantly upon failure of your primary broadband line (FTTH/FTTO fiber). Powered by an industrial SD-WAN router and multi-carrier SIM cards, traffic fails over in under 30 seconds, preserving mission-critical services such as POS card terminals, VoIP telephony, and ERP access.

Q: Why choose 5G backup over traditional 4G?

Unlike 4G, Welink Tech's 5G backup delivers fiber-grade throughput (up to 1 Gbps) with ultra-low latency (<20ms). It effortlessly supports high-concurrency environments, cloud-based applications, and multi-party video conferencing where a standard 4G link would saturate under heavy team load.

Q: Can 5G backup be used permanently as our primary connection?

Yes. Welink Tech's solution frequently operates as Primary Wireless Access, particularly for branch locations without fiber access or awaiting civil streetworks. Pairing an industrial 5G gateway with high-gain directional antennas yields throughput and stability matching leased-line fiber.

Q: What is the lead time to install an emergency backup connection?

Welink Tech commits to delivery and commissioning of emergency backup kits within 24 business hours across France. In Greater Paris, our technicians can intervene on site in under 4 hours for Premium contracts. The equipment arrives pre-configured: simply plug into power.

Q: How does automated failover operate during a fiber cut?

The SD-WAN gateway sends continuous ICMP/TCP heartbeats to reference destinations. Upon link loss detection on the primary fiber port, traffic routes to the active 4G/5G cellular link in under 30 seconds. Session persistence prevents VPN drops, active ERP timeouts, or dropped phone calls.

Q: Which regions does Welink Tech serve for emergency deployments?

Welink Tech delivers across all of mainland France: Paris & Île-de-France (express dispatch <4h), Lyon, Marseille, Bordeaux, Lille, Nantes, Toulouse, Strasbourg, Nice, and Montpellier. We also serve Belgium, Switzerland, Germany, and Western Europe on demand.

Guarantee business continuity with our professional enterprise internet solutions. 4G/5G SD-WAN cellular backup, temporary high-density Wi-Fi, emergency link: a redundant network architecture guaranteeing 99.99% uptime.

Supervise, synchronize, and centralize your operations in real time. With Welink Tech, streamline your connectivity with an industrial multi-carrier SD-WAN router, 24/7 NOC oversight, and priority technical support.

The Reality

How much does 1 hour without Internet cost your business?

For the vast majority of businesses (retail, logistics, corporate, healthcare), an optical fiber outage quickly escalates into thousands of euros in direct and indirect revenue loss.

According to a benchmark Gartner study, the average cost of an enterprise IT outage is €5,600 per minute for mid-sized organizations. Furthermore, telecom regulators report a 28% increase in optical fiber cuts across France in 2024, driven primarily by civil streetworks and distribution cabinet vandalism.

4G/5G SD-WAN Backup: Automated Failover

Upon physical disruption of your primary fiber (FTTH/FTTO), our industrial SD-WAN edge router detects link loss in milliseconds via continuous ICMP/TCP heartbeats. IP failover executes across bonded 4G/5G cellular channels in under 30 seconds, maintaining all active sessions (VoIP, VPN, ERP). The router simultaneously bonds 2 to 4 distinct carrier SIMs (Orange, SFR, Bouygues, Free) to guarantee absolute availability.

wifi

High-Throughput Multi-SSID Enterprise Wi-Fi

Carrier-grade WLAN architecture for demanding enterprise venues. Multi-SSID partitioning by workload: staff corporate network (WPA3-Enterprise with RADIUS 802.1X), guest Wi-Fi with branded captive portal, and an isolated IoT VLAN for sensors and IP surveillance cameras. Granular DSCP QoS prioritization prevents guest traffic from starving critical transactions.
