Nationwide Grocery Chain
Cuts POS Downtime by
94% with NK C100
A 280-store grocery chain replaced aging fixed-line POS connections with the NetKonnekt NK C100 4G router — achieving near-zero transaction failures, faster checkout throughput, and seamless connectivity even during peak holiday seasons.

The Challenge
When the Network Fails, Every Second Costs Money
Fresh & Easy Grocery Co. operates 280 stores across the Southwest and Midwest. Like many large retail chains, they relied on ageing fixed-line broadband and DSL connections for their POS terminals — a setup that had worked for years but was increasingly showing its limits.
During high-traffic periods — weekday evenings, Thanksgiving week, and Black Friday — connectivity issues became a recurring crisis. Registers would lose connection to the payment processor, card transactions would time out, and self-checkout kiosks would go offline, forcing customers into long queues at staffed lanes. The operations team estimated that each 15-minute outage across a single store cost over $3,000 in lost sales and labor overhead.
With 280 stores affected at varying times, the total annual cost of POS-related downtime was estimated at over $8.4 million — not including the indirect cost of eroded customer trust.
Fixed DSL and cable lines failing during peak-hour traffic spikes, taking POS systems offline mid-transaction
ISP technician response times averaging 48–72 hours, leaving stores on manual cash-only operations for days
No centralized visibility into which stores were online — IT teams discovered outages only when store managers called in
Self-checkout kiosks and digital price display systems sharing the same unreliable connection, compounding failures
The Solution
NK C100 as Primary & Failover Connectivity Layer
After evaluating several enterprise networking vendors, Fresh & Easy’s IT team chose NetKonnekt’s NK C100 4G LTE router as the foundation of their new connectivity architecture. The NK C100’s dual-SIM capability, rugged compact form factor, and remote management portal made it uniquely suitable for a rapid, large-scale retail rollout.
The deployment strategy was straightforward: NK C100 units would operate as the primary internet connection at smaller-format stores and as an always-ready cellular failover at flagship stores that retained their fiber lines. In both configurations, POS terminals, self-checkout kiosks, digital signage, and inventory management systems were routed through the NK C100.
Site Survey & SIM Carrier Selection
NetKonnekt’s deployment team assessed cellular signal strength at all 280 locations, selecting the best-performing carrier per site from AT&T, T-Mobile, and Verizon — ensuring optimal coverage before hardware shipped.
Zero-Touch Provisioning
NK C100 units were pre-configured at NetKonnekt’s staging facility with store-specific network profiles, VPN credentials, and QoS rules. Stores received plug-and-play units — no IT staff on-site required.
Phased 6-Week Rollout
Stores were migrated in batches of 50 per week, prioritized by historical downtime frequency. The final 280 stores were live within 42 days — completing 3 weeks ahead of the projected timeline.
Centralized Monitoring Dashboard
All 280 NK C100 units were enrolled in NetKonnekt’s remote management portal, giving IT a real-time map of every store’s connectivity status, data usage, and signal quality — accessible from any browser.

The Numbers Speak for Themselves
Downtime Reduction
POS outage time dropped from 4.2 hrs/mo per store to under 15 minutes after deployment
Failover Speed
Automatic failover to cellular backup triggered in under 30 seconds — imperceptible to cashiers
Stores Deployed
Full rollout completed across all 280 stores in 42 days — 3 weeks ahead of the original schedule
Annual Savings
Estimated annual savings from prevented downtime, labor overhead, and recovered transactions
We’d been fighting POS outages for three years — losing sales, losing customers, losing sleep. The NK C100 rollout was the smoothest infrastructure project I’ve managed in 15 years in retail IT. Six weeks, 280 stores, and our first Black Friday with zero regional outages. The ROI calculation took about 30 seconds.
