Comprehensive and reliable mobile connectivity has become essential in today’s fast-paced retail landscape. Shoppers at stores across South Africa expect to instantly access product details, compare prices, tap into loyalty apps, and complete mobile payments. Underpinning that experience is flawless cellular coverage.

But it is not just customers who suffer when the signal fails. Retailers rely on real-time inventory systems, PoS transactions, and staff communications. When mobile coverage drops, queues grow, transactions falter, and revenue dips. Research shows that a 1 % uptick in shopper dwell time can boost sales by 1.3 %, highlighting just how critical consistent connectivity is.

While Wi‑Fi is often the go-to solution, mobile networks bring stronger encryption, more reliable coverage, and better support for roaming customers. They are less prone to traffic congestion and hacking. In South Africa, this is especially critical, as compliance and trust are essential at a time when digital payments and loyalty systems are taking off.

Introducing CEL‑FI boosters

That is where Duxbury steps in. As South Africa’s authorised distributor of Nextivity CEL‑FI cellular boosters, we deliver carrier-approved, scalable solutions designed specifically for retail environments. These boosters amplify weak indoor signals, patching coverage gaps while adhering to mobile operator standards.
