This DECT multi-cell system intends to create an extremely scalable and reliable solution for organisations of any size and any shape.

The Yealink W90 DECT IP Multi-Cell System brings seamless stability. The rotatable external antennas ensure further signal range, industry-leading coverage, and flexible steering for complex areas, which truly saves amount and cost of bases in deployment with industry-leading coverage.
