Yealink W90B DECT Multi-Cell Base Station
PRODUCT DESCRIPTION
Yealink W90B DECT IP Multi-Cell Base Station for W90 System (W90B) - 1 Year Local Warranty
Flagship Multi-Cell DECT Base Station for the Largest Sites
The Yealink W90B is the radio cell of Yealink's flagship W90 multi-cell DECT platform. Deployed under a W90DM DECT Manager, up to 60 W90B bases form one cordless network carrying 250 handsets and 250 simultaneous calls — built for warehouses, hospitals, hotels and multi-location sites.
External Antennas, 50 m Indoor / 300 m Outdoor Range
With external antennas for further signal range and flexible steering in complex areas, each W90B covers 30–50 m indoors (ideal distance 50 m) and 300 m outdoors in ideal conditions, carrying up to 8 wideband calls (4 active handsets) or 8 narrowband calls per base.
Air + LAN Sync with Level-1 Base Backup
W90B bases synchronise over the air or over the LAN for stable roaming even in poor-signal environments, and if the Level-1 sync base goes offline, a backup base takes over within one minute. Handsets enjoy seamless handover as staff move around site.
One-Cable PoE Installation
The compact W90B powers over a single PoE (IEEE 802.3af, Class 1) cable, with an optional power adapter where PoE isn't available, and is provisioned centrally through the W90 system.

Frequently Asked Questions — Yealink W90B
Does the W90B work without a W90DM?
No — the W90B is a multi-cell base station managed by the W90DM DECT Manager. For a single-base office, choose a W70B or a W73P system instead.
How many calls can one W90B carry?
Up to 8 wideband calls (4 active handsets) or 8 narrowband calls per base; one W90DM system carries up to 250 simultaneous calls.
What coverage does each base give?
Per the official datasheet, 30–50 m indoors (ideal distance 50 m) and 300 m outdoors in ideal conditions. SourceIT can advise on base placement for Singapore buildings.
How is the W90B different from the W80B?
The W90B belongs to Yealink's higher-capacity W90 platform, with external antennas, LAN synchronisation and VIM scaling. For smaller multi-cell sites, see the W80B.
Which handsets are supported?
The W73H, W78H, W56H, W71H, W74H, rugged W57R and W59R, WH62/WH63 DECT headsets, plus CP930W and CP935W conference phones and DD Phone.
Does the Yealink W90B come with local warranty in Singapore?
Yes. Every W90B sold by SourceIT comes with a 1 Year Local Warranty in Singapore and a GST invoice.
