Broadband technology expert witness candidates typically have extensive experience and a background in wireless technology, electrical engineering, computer engineering, mobile technology, telecommunications, and/or have specialized knowledge in wireless communication and wireless network technology.

Broadband refers to high-speed and high-bandwidth transmission technologies used to transmit data, voice, and video across long distances. Broadband service providers can be telephone or cable companies, internet service providers (ISP), a wireless network provider (cell phone) or satellite service. In telecommunications, broadband transports multiple signals via coaxial cable, fiber optics, radio or twisted pair. Broadband internet service is offered in four different forms:

Mobile broadband is a term used by wireless carriers to describe mobile Internet access that uses the mobile phone infrastructure, or cellular network.

Often, matters requiring broadband expert witness work involve intellectual property, such as patent infringement litigation or trade secret disputes. Expert witness services by a broadband expert witness could include expert consulting, expert report preparation, expert opinion, depositions and/or expert testimony in the courtroom. In a high-profile case, or litigation involving a significant financial stake, an attorney may require a technical professional with prior expert witness testimony experience. In addition, clients often seek an industry expert for pre-litigation consulting work. While many experts have broadband technology expertise, an expert witness carries the additional responsibility of providing testimony before the court in a manner whereby lay people can understand the technology and evidence.

Cahn Litigation Services has the experience required to turn an expert witness search around quickly. The firm has an earned reputation for providing candidates with the right balance of expertise and testimony to support each project and it nuances.
