Yealink W90B DECT IP Multi-Cell System
PRODUCT DESCRIPTION
Yealink W90B DECT IP Multi-Cell System (1302015) - 2 Years 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 hospitals, factories, hotels and campuses across Singapore.
External Antennas, 50 m Indoor / 300 m Outdoor Range
With external antennas, each W90B delivers 30–50 m of indoor coverage (ideal distance 50 m) and up to 300 m outdoors in ideal conditions, handling up to 8 wideband calls (4 active handsets) or 8 narrowband calls per base. Add bases wherever coverage or call density demands.
Air + LAN Sync with Level-1 Base Backup
W90B bases synchronise over the air or over the LAN for stable roaming even in interference-prone environments, and if the Level-1 sync base goes offline, another base takes over within a minute. Handsets enjoy seamless handover and roaming as staff move around site.
One-Cable PoE Installation, Central Management
The compact, wall-mountable W90B powers over a single PoE (IEEE 802.3af) cable and is managed entirely from the W90DM's web UI — with auto-provisioning, OTA firmware upgrades and TLS/SRTP/DECT-encryption security.

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 is the W90B different from the W80B?
The W90B belongs to the higher-capacity W90 platform (60 bases / 250 handsets per DM vs 30 / 100 for the W80B system), has external antennas, and supports LAN synchronisation and Level-1 base backup for greater resilience.
How many calls can one W90B carry?
Up to 8 wideband calls (4 active handsets) or 8 narrowband calls per base; the whole system scales to 250 simultaneous calls per DM.
What coverage does each base give?
Per the official datasheet, 30–50 m indoors and up to 300 m outdoors in ideal conditions. SourceIT can advise on base placement and site surveys for Singapore buildings.
Which handsets are supported?
The W73H, W78H, W56H, W53H, W71H, W74H, rugged W57R and W59R, plus CP930W and CP935W conference phones.
Does the Yealink W90B come with local warranty in Singapore?
Yes. Every W90B sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
