WT41N0 VOW Wearable Computer

The next generation in rugged wearable voice-only mobile computers

Set your workers’ hands free to increase productivity and eliminate errors in your warehouse or distribution center with next generation hands-free voice applications. If your workers are handling packages in a parcel and post sortation facility or moving materials in, through and out of the warehouse, give them powerful voice-directed applications that will let them get the job done faster and right in every inch of your warehouse — including the freezer. With the WT41N0 VOW on the arm or hip of your workers, voice direction can walk them through their tasks, so they can keep their hands and eyes on the items they are moving. Workers can count on crystal clear voice quality. Voice-directed applications are highly intuitive, so there is very little training required. And applications are easily delivered in the native language of your workers.

WT41N0 VOW Wearable Computer

Superior Application Performance

The WT41N0 offers the most power of any device in its class, with a dual core processor and an operating system that can take advantage of both processors — Microsoft mobile operating system, Windows Embedded Compact 7. Combined with 2GB Flash memory and support for 802.11a/b/g/n wireless LANs, the device delivers the processing power and network throughput required to deliver consistent, lightning-fast application performance and reliability.

Instant RS507 Bluetooth Pairing

Users can instantly add hands-free 1D and 2D scanning at the start of a shift by simply scanning the special Bluetooth pairing bar code printed directly on the WT41N0 VOW with the Zebra® RS507 Bluetooth ring-scanner.

Powerful Voice Functionality

Create highly intuitive and easy-to-use voice-directed applications with support for voice recognition and text-to-speech engines. The ability to simultaneously support multiple audio sources greatly enriches functionality. For example, an associate in training can use a wired headset for voice picking, while a supervisor standing near the trainee can listen in via a Bluetooth headset.

All the Right Accessories

Enrich the functionality of this hands-free solution with our complete accessory family. Our RS507 and RS419 ring scanners give your workers hands-free scanning that boosts productivity in the most scan intensive applications. Our rugged RCH51 cabled headset provides crystal clear voice in the noisiest and most demanding environments delivering an end-to-end cost-effective and complete voice-directed platform.

Ready for Rugged Environments

A drop and tumble test plus an IP sealing rating provide true peace of mind — you can count on reliable operation even if workers drop, bump or spill liquid on the WT41N0. Stainless steel connectors and an improved coating on the rear cleat eliminate corrosion and increase durability at accessory attachment points. The result is superior uptime, a rapid return on investment and a low total cost of ownership.

Improve the productivity and accuracy of your workers with
best-in-class voice-directed hands-free computing.
