Wireless Pick-to-Light : the end of the barrier to adoption ?
Pick-to-light no longer needs to prove its value.
Fewer picking errors, faster throughput, less cognitive fatigue for operators : the benefits have been documented for years and are widely recognised, in warehouses as much as on production lines.
And yet a significant share of warehouses that could benefit from it still haven't adopted it.
The reason is almost never the technology itself. It's what comes with it : cabling.
The real barrier was never the concept : it was the installation
An installation cost that can exceed the cost of the solution itself
In a traditional warehouse, equipping a picking zone with wired systems means running cables along every rack, protecting them, connecting them to a stable power supply, and leaving margin for future changes.
In older buildings or metal structures, this work can represent as large a share of the budget as the light indicators themselves.
For mid-sized configurations (a few dozen to a few hundred locations), this installation overrun is often enough to tip a project toward "not now."
A rigidity that doesn't match the reality of the modern warehouse
A wired system locks down the physical layout of the space.
Reorganizing racks, opening a new aisle or updating a product reference then requires recabling.
But today's warehouses are no longer static : seasonal peaks, new references, the growth of e-commerce flows all demand a level of adaptability that wired infrastructure simply can't follow without recurring costs.
The false choice between pick-to-light and alternative solutions
Faced with these constraints, some warehouses turn away from pick-to-light toward other approaches : pick-to-voice, RF scanning, picking carts equipped with tablets.
These solutions have their own merits, particularly for multi-order operations or very low SKU-density environments. But they solve a different problem : they don't address the speed of visual recognition that a direct light signal at the picking location provides.
The real question, then, isn't "pick-to-light or something else", it's "how do we deploy pick-to-light without the constraints of cabling."
What wireless changes
An installation measured in minutes, not days of site work
Wireless Pick-to-Light and Put-to-Light indicators attach directly to racking, bins or workstations : magnetically or by clip, with no electrical work involved.
A deployment that once required several days of site work can now be completed in a few hours, with no electrical engineering study and no work permit.
A flexibility finally aligned with the real needs of the warehouse
Reorganising a picking zone, adding a reference or responding to a seasonal peak no longer requires recabling. Indicators can be moved and reconfigured in minutes.
This flexibility changes the very nature of pick-to-light projects : they become viable for temporary configurations, seasonal storage or short-term warehouses, use cases that were economically unjustifiable with wired infrastructure.
A battery life that wasn't guaranteed in early wireless solutions
Early generations of wireless sensors long suffered from limited battery life, which held back adoption in environments where frequent maintenance isn't an option.
Current solutions, built on architectures designed for low power consumption, now reach several years of battery autonomy : a shift that has done much to make wireless credible for large-scale deployments.
A responsiveness that no longer requires a trade-off
The most common technical objection to wireless remains latency : can a radio signal really be as fast as a wired one ?
On modern LPWAN protocols, response time is now under one second : comparable to traditional wired systems, and fast enough to avoid any disruption to operator pace.
Who this change matters most for
Warehouses and production lines that evolve frequently (new references, seasonal reorganisations, gradual growth in activity) are the first to benefit from this shift to wireless.
The same goes for sites that previously couldn't justify a pick-to-light project on economic grounds : mid-sized warehouses, temporary logistics sites, or workshops where cabling raises safety or access issues.
For logistics and industrial leaders who had shelved this topic for lack of a clear ROI, it's worth revisiting.
What's changed isn't the underlying technology, it's everything that surrounds it.
