London Power amplifier specialist Wireless Systems International has closed its doors and laid off 53 employees. The Bristol, UK based designer and manufacturer of base-station amplifiers for wireless systems was placed in administration late last month, but administrators Baker Tilly failed to sell the company as a going concern.
Most of the assets at WSI have been sold to US antenna and wireless infrastructure group Andrew Corporation for an undisclosed sum. The assets include Intellectual Property relating to PA design, including the Adaptive Parametric Linearisation technology and techniques relating to RF and digital predistortion, as well as equipment and stock.
WSI's test, development and assembly plant, in Cwmbran, Wales has also been closed and a manufacturing partnership with Flextronics terminated.
The main backers of WSI were venture capital groups 3I, Advent Venture Partners and Deutsche Bank. About £17m has been invested in the company over the pat three years, as well as regional development grants for the Welsh facility, which was officially opened in April 2001.
Cedric Clapp of Baker Tilly said the administrators "worked day and night to sell the business as a going concern. [But] the nature of the business meant that we had a window of opportunity to sell lasting just days."
Clapp said "the high costs involved in maintaining this business made a going concern sale untenable in the current business climate. The conclusion of a sale of the technology and equipment (to Andrew Corporation) is an achievement in itself given the risks and uncertainty in [the] global telecoms market today."
