Overview:

The Yealink W90B is a multi-cell DECT base station designed for large business environments that require reliable wireless voice coverage and support for a high number of users. It forms part of the Yealink W90 Multi-Cell DECT solution and is suitable for warehouses, factories, car dealerships, offices and other large deployments where users need to move freely between coverage areas.

Description
The Yealink W90B provides scalable DECT connectivity for large installations, supporting up to 250 handsets, 250 VoIP accounts and 250 simultaneous calls when deployed as part of a W90 Multi-Cell system. Seamless roaming and handover allow users to move between W90B base stations without dropping active calls. Synchronisation can be performed over the DECT air interface or through the LAN, giving installers greater flexibility when planning the network.

A Yealink W90DM DECT Manager is required for W90 Multi-Cell deployments. The DECT Manager centrally handles roaming, handover and system management, making it easier to deploy, maintain and expand the network as requirements grow.

Features:

Yealink W90B for Large DECT Deployments
The W90B is built for environments where a single DECT base station is not enough. Up to 60 W90B base stations can be connected in one network, supporting up to 250 handsets. This makes the system suitable for larger sites where employees need dependable voice communication while moving between different areas of a building or property.

The system also supports up to 250 SIP accounts and 250 simultaneous calls, providing considerable capacity for busy business communications.

Reliable Wireless Coverage and Roaming
Seamless handover allows calls to continue while users move between W90B base stations. Centralised management through the W90DM helps maintain consistent operation across the multi-cell network.

The W90B provides a coverage range of up to 50 metres indoors and up to 300 metres outdoors, depending on the environment and installation conditions. DECT and LAN synchronisation options provide additional flexibility when installing base stations across a larger site.

Compatible Yealink Devices
The Yealink W90B supports a range of compatible DECT and wireless devices, including the W53H, W56H, CP930W and DD Phone configurations using the T41S and DD10K bundle. This allows businesses to build a system around compatible handsets and communication devices rather than replacing their entire DECT environment.

Business Communication and Call Handling
The W90B supports essential business calling functions including call hold, call transfer, 3-way conferencing and switching between active calls. Caller ID can display both the caller name and number, helping users identify incoming calls quickly.

With up to two simultaneous calls supported per handset, the system can handle busy communication requirements while maintaining the flexibility expected from a multi-cell DECT deployment.

Flexible W90 Multi-Cell Expansion
One of the main advantages of the W90B is its scalability. Businesses can expand their DECT coverage by adding base stations rather than replacing the entire system. The W90B primarily acts as the wireless base station responsible for transferring media traffic, allowing the network to provide extended coverage across larger premises.

The option to synchronise base stations through LAN or DECT gives installers more choice when dealing with different building layouts and network conditions.

Yealink W90B Part Number / SKU
The part number / SKU for this product is W90B. It is the base station component of the Yealink W90 Multi-Cell DECT solution and must be deployed with a W90DM DECT Manager for a complete multi-cell installation.

Why Choose the Yealink W90B?
The W90B is a practical choice for businesses that need scalable cordless communication across large premises. It combines extended DECT coverage, centralised roaming management, high user capacity and flexible synchronisation options in a system designed for professional deployments.

For warehouses, factories, dealerships and large offices, the ability to move between base stations without losing an active call can make day-to-day communication considerably more efficient. The system can also grow with the business, allowing additional base stations and compatible handsets to be incorporated as coverage requirements increase.
