Product Overview
The Yealink W90 Multi-Cell DECT solution is Yealink’s most powerful and scalable wireless DECT system, designed to meet the communication needs of large enterprises, warehouses, factories, hospitals, car dealerships, and campus environments.

Capable of supporting up to 60 base stations (W90B) and 250 handsets within a single network, the system delivers 250 SIP accounts and 250 simultaneous calls. This makes the W90 the largest and most advanced DECT solution from Yealink to date.

With seamless handover and roaming between base stations, the system ensures uninterrupted communication for mobile staff. Central management is handled by the W90DM DECT Manager, simplifying deployment, scaling, and administration. Base station synchronisation can be achieved through the DECT air interface or via LAN interface, offering flexible installation options to suit different environments.

Note: All deployments of the Yealink W90 Multi-Cell DECT solution require at least one W90DM DECT Manager.
