LONDON, Nov 19 (Reuters) - Sequans Communications, a French maker of chips used in high-speed wireless networks, has picked Jefferies JEF.N and UBS UBSN.VX to help it prepare a $100 million Nasdaq listing, people familiar with the matter said.
Sequans has also engaged Frank Quattrone's technology boutique, Qatalyst Partners, in an "equity advisory" role on the initial public offering (IPO), the people added.
Paris-based Sequans, which is backed by Alcatel-Lucent SA ALUA.PA, Motorola Inc MOT.N, Swisscom AG SCMN.VX and several financial investors, asked banks to pitch for roles on a New York listing, Reuters reported last month. [ID:nLDE69O25H]
Jefferies, Qatalyst, Sequans and UBS did not immediately respond to requests for comment.
Sequans was founded in 2004 by Chief Executive Georges Karam, a former Juniper Networks Inc (JNPR.N) executive. It initially made chips based on so-called WiMAX technology but since last year has also worked to the rival "Long-Term Evolution" (LTE) standard, which is gaining ground.
Companies including Acer Inc (2353.TW), Cisco Systems Inc (CSCO.O) and Huawei Technologies Co Ltd [HWT.UL] use its chips in the hubs, known as base stations and subscriber stations, that underlie fourth-generation (4G) wireless networks. (Reporting by Quentin Webb; Editing by David Holmes)
