BT has won a three-year deal to supply UK courts with Wi-Fi hotspots, aiming to speed up the legal system by making sure jurors, lawyers and judges have access to the most up-to-date information.
Seven courts in England and Wales are being Wi-Fi enabled by BT OpenWorld as part of the trial.
Lawyers would benefit by being able to research new points of law as and when they arise, according to Lord Justice Thomas, senior presiding judge of England and Wales.
"The hotspots should enable lawyers to access information held at their offices, or receive emails and have information sent to them while they are attending court," he said in a statement.
Courts Minister Christopher Leslie explained that the hotspots would also benefit jurors.
"Lawyers, jurors, expert witnesses and the public will be able to access the internet or their office files while waiting to be called to court," he said.
"It makes delays during proceedings more productive and less inconvenient for those attending court."
The Royal Courts of Justice, along with Southwark, Birmingham and Swansea Crown Courts, and Winchester, Liverpool and Leeds Combined Courts, will take part in the trial.
The Department of Constitutional Affairs, which oversees courts in England and Wales, will decide on whether to extend the scheme at the end of the trial.
