➀ Blu Wireless, a specialist in mmWave technology based in Bristol, and Nomad Digital, a railway system integrator, have deployed superfast wireless connectivity on a key commuter line through Silicon Valley, California. They have implemented Blu Wireless' mmWave system, LightningBlu, for onboard Wi-Fi on Caltrain's electrified service. The technology offers high connectivity speeds to train passengers across San Francisco. ➁ Key features of LightningBlu include minimal interference, extended range between access points, and reduced infrastructure needs. ➂ The project is part of Caltrain's modernization efforts and is expected to be explored across various rail environments.
