In fast-paced environments like warehouses, hospitals and retail hubs, businesses are moving beyond the limitations of traditional desk phones and fixed communication systems.
Historically, many cordless business phones relied on DECT infrastructure, which often required dedicated base stations, additional cabling and separate network management. Modern WiFi 6 VoIP phones take a different approach by using existing wireless infrastructure to deliver voice, video and mobile workflows across an entire facility.
This is where the Grandstream WP Series stands out.
Rather than creating a separate cordless network, the WP Series uses WiFi 6 technology to provide seamless roaming, HD voice and enterprise mobility using the same wireless infrastructure already supporting laptops, tablets and business devices.
For businesses upgrading communication systems, this can help:
- Reduce infrastructure and deployment costs
- Improve roaming in high-density environments
- Simplify device management
- Support fully mobile staff workflows
DECT vs WiFi 6 Cordless Phones

The WP856: More Than a WiFi Phone
The WP856 moves beyond traditional cordless telephony by combining communication, Android applications and video functionality into one device.
Running Android 13 with Google Mobile Services support, users can install workplace applications directly from the Google Play Store, including Microsoft Teams, Slack, inventory management software and warehouse management platforms.
Combined with integrated barcode scanning, video calling and WiFi 6 connectivity, the WP856 effectively becomes a mobile workstation rather than just a cordless handset.
For warehousing, logistics and retail environments, this creates several advantages:
- Scanner and phone combined into one device
- Reduced hardware costs
- Fewer devices for staff to carry
- Centralised communication and workflows
- Improved mobility across larger facilities
