Building Tomorrow’s Telecommunications Network Today

The current 5G evolution in network connectivity is expected to drive unprecedented demands for bandwidth, reliability, and security. However, a network of this magnitude and robustness doesn’t pop up overnight and enterprises and consumers are just beginning to realize the myriad use cases a 5G network can support. For example, consider the increased number of connected devices in a house like smart thermostats, security cameras, tablets, smartwatches, and mobile phones, of course. Raj Savoor, the vice president of network analytics and automation at AT&T Labs explains, “Currently we estimate the average consumer home footprint has about 13 connected devices, including mobile and other devices.” And although that sounds like a large number, he continues to explain the real scale, “That's going to increase to 30 to 40 devices over the next five years, so a really big increase.” And the real challenge he continues to explain is that, “This growth needs advanced network architectures to support, manage and provide fast, secure, and reliable services.” Bandwidth will also increase five times in the next five years, according to Savoor, as consumers adopt immersive interactive applications. Immersive experiences also require lower latency and jitter, and a lot more security and reliability. For a company like AT&T that supports a large existing network, building the next generation network requires an incremental approach. In fact, AT&T’s 5G network has been years in the making. “We look at it as a journey. There are a lot of steps that we've taken over the past few years to build on it, and we have prepared for the next step,” says Savoor. And as businesses and consumers transition to a 5G world, AT&T keeps looking ahead. “We are thinking about the next 20 and 50 years. Network investments take a long time, and we want to make those investments with economics in mind, but also very much ensuring the most reliable network offering,” says Savoor.
