ClearLink® In-building Wireless

Did you know that an average of 75% of wireless calls start within a building? While in these buildings, it is common for mobile customers to experience poor or non-existent capacity, coverage and performance issues. And, unbeknownst to many, these issues do not lie solely with the wireless carrier, but more so with the structure of the building itself.

As more people utilize mobile devices and data-intensive services in areas such as stadiums, universities, airports and office buildings, the demand for wireless coverage across a reliable network continues to increase dramatically.

Enter Westell’s ClearLink®, the industry-leading in-building wireless solution that provides the core infrastructure needed to facilitate or extend wireless services into buildings of all types and sizes. Designed to improve network performance while minimizing operating and capital costs, ClearLink® ensures the premium wireless coverage and capacity required to optimize the customer experience.

ClearLink® In-Building Wireless (IBW) solutions

Westell offers a line of antennas and their corresponding hardware to support in-building wireless communications. Directional antennas are offered for external base station connectivity and omni-directional distribution antennas are offered for internal aggregation and distribution.

Westell’s antennas are available with various gain levels and directivity options depending upon the specific application requirements.

Available antenna options include:

Bi-directional Amplifiers (BDAs)
Westell’s, formerly CSI, Bi-Directional Amplifiers (BDAs) provide a means to receive and amplify the signal from a cellular tower for distribution throughout a building or structure allowing users to utilize mobile phones within a facility. Available in a variety of gain and power options, Westell BDAs have been utilized in nearly every application including tunnels, campus environments, high-rise office buildings, warehouses, and residential locations. ClearLink DAS
ClearLink DAS is an advanced in-building distributed antenna system (DAS) used to enhance high-speed cellular technologies, such as LTE, and provide outstanding coverage with superior data rates within buildings. Westell’s ClearLink® DAS is engineered to deliver exceptional system performance with unparalleled flexibility and scalability, and provides advanced features to simplify DAS commissioning and optimization.

Westell’s ClearLink® DAS addresses the Near-Far problem. The ClearLink DAS mitigates signal degradation and subsequent performance issues caused by Near-Far performance reduction when a mobile device is operating within a DAS coverage area, but is being serviced by a distant macro cell tower.
