Advances in wireless technologies are driving innovation in virtually every industry, from automobiles to consumer electronics. We recently asked 10 engineers to prognosticate on the future of wireless technology. Eileen Liu, a software engineer at Lockheed Martin, writes:
Wireless technology has become increasingly prevalent in our daily lives. It has become commonplace to look up information on smartphones via invisible networks and to connect to peripheral devices using Bluetooth connections. So what should we expect to see next in the world of wireless technology? One of the major things to keep an eye on is the effort for a global Internet network. Facebook and Google are potentially collaborating, working on drones and high-altitude helium balloons with router-like payloads. These solar-powered payloads make a radio link to a telecommunications network on Earth’s surface and broadcast Internet coverage downwards. Elon Musk and Greg Wyler are both working on a different approach, using flotillas of low-orbiting satellites. With such efforts, high-speed Internet access could become possible for the most remote locations on Earth, bringing access to the 60% of the world’s population that currently do not have access. Another technology to look out for is wireless power transfer. This technology allows multiple devices to charge simultaneously without a tether and without a dependency on directionality. Recent developments have mostly been in the realm of mobile phones and laptops, but this could expand to other electronic devices and automobiles that depend on batteries. A third technology to look out for is car-to-car communications. Several companies have been developing autonomous cars, using sensor systems to detect road conditions and surrounding vehicles. These sensors have shown promise, but have limited range and field-of-view and can easily be obstructed. Car-to-car communications allow vehicles to broadcast position, speed, steering-wheel position, and other data to surrounding vehicles with a range of several hundred meters. By networking cars together wirelessly, we could be one step closer to safe autonomous driving.
