5G is the fifth generation of wireless network technology, and is the latest technology for connecting wireless devices to cellular networks. It’s predecessor, 4G technology, brought us increased data transfer speeds, which enabled the adoption of cloud and streaming services, video conferencing, and Internet of Things devices. 5G technology has the potential to foster innovative smart devices that will be constantly communicating and providing faster service.
4G LTE technology uses long-range signals transmitted across a low frequency radio wave spectrum over a broad network of cell sites. 5G operates on a different part of the spectrum, which results in faster download speeds and more stable connections for wireless devices, but these waves frequencies have a shorter range, thus requiring more cell sites.
Often, matters requiring 5G technology expert witness services involve intellectual property, such as patent infringement litigation or trade secrets. In a litigation scenario, an expert witness can expect courtroom testimony, as well as other expert witness services including depositions, an expert report, reverse engineering, forensic analysis, and related consulting activities. In high profile cases, or litigation involving a significant financial stake, previous expert witness experience is often a requirement.
Cahn Litigation Services has a vast network of experts and often receives calls from an attorney firm, typically litigators, to help locate a wireless technology expert that can support cases involving 5G technology matters. At Cahn Litigation Services, sourcing wireless technology expert witnesses for patent litigation is a particular area of expertise.
Please Note: All Cahn Litigation expert witness searches are customized to attorneys' precise specifications and preferences. Attorneys are encouraged to discuss search parameters with a Cahn search specialist.
