Broadband

A broadband technology expert witness typically has extensive experience and possesses a background in wireless technology, electrical engineering, computer engineering, mobile technology, telecommunications, and/or has 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: DSL (Digital Subscriber Line), fiber-optic, cable, and satellite. 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, as an example patent infringement litigation. Expert witness services by a broadband expert witness could include expert consulting, an expert report, expert opinion, and/or expert testimony. In a high-profile case, or litigation involving a significant financial stake, an attorney may require a testifying expert 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.
