Case Study 1 - WCDMA Base Station

The client was an SME company that manufactures and supplies mobile GSM base-station products for use by governmental security agencies. They wanted to develop their product range, and competitiveness, by being the first company to offer a WCDMA based product that would operate with 3G mobile phones.

Wireless Solutions worked with the client to define use cases and requirements specifications for the base station, and then undertook a product development programme to design a new 3G mobile base station, based upon a COTS pico-Node B plus bespoke RF module, high power RF PA, microprocessor modules and high current PSUs.

Design Challenges

The design presented numerous challenges around packaging, thermal management, power management and flexibility of installation.

The unit had to incorporate multiple highly complex systems in very close proximity with high-power RF. Each system had its own power supply and thermal requirements as well as needing to fit within demanding space constraints, with allowance for practical routing of RF, power, and data connections.

Our Involvement

Wireless Solutions developed all of the base station hardware, including complex mechanics, with the client developing specialist software to deliver the required overall system functionality.

A number of fully functioning prototypes were delivered to the client along with a full manufacturing data-pack which defines all processes required for the client to manufacture the unit.

Wireless Solutions also stepped in to manufacture units to meet urgent customer demands, and to diagnose & repair damaged units returned from the field.

The product became a successful and leading component of the client’s product range and is in use by government security agencies around the world.
