b'5G IN THE DoDspectrum wavelengths. One area is the mid-band layer of spectrum, known as sub-6, where existing 4G and 4G LTE networks are already concentrated. The 5G solutions that leverage the high band are known as millimeter wave, or mmWave, and could be even more game changing. Those high-band solutions that can process significantly larger volumes of data, communicating and transmitting at extremely high speeds, though they have coverage and propagation limitations. AT&T is planning advances in both realms.For the DoD, our vision is that well use a combination of the two, says Bill Lantzy, client executive vice president for AT&T Public Sectors Navy division. Its really going to be driven by the application or use, in terms of latency and bandwidth. Were not just going to rely on millimeter wave or sub-6 wave. Preparing for the future of 5G will require coordination with service providers. Jill Singer The spectrum that supports 5G development is scarce and the subject of fierce competition. DoD is working on a strategy to share some of the relevant spectrum it owns with carriers for 5G development. Its the scarcity of the resource and the exponential increase in the demand for connectivity that 5G is driving that creates this opportunity for dynamic spectrum sharing, Singer says.Implementing 5G also amplifies whats known as edge computing, which could bring a sea of change in how both DoD and the private sector operate. Simply put, computing at the edgewhat AT&T calls network edge computing, or NEC, is the fusing or convergence of the cloud into the network. The idea is to push computing power closer toward the device or other endpoint where its most efficient. A related concept known as Multi-access Edge Compute allows carriers to route specific data traffic for local processing. It essentially acts as a shortcut in the data processing flow, by allowing a customer to designate specific data traffic to be processed by specific applications on the customer premises, which significantly reduces latency. This can lead to cost savings and enhanced data security, as the designated customer data isnt routed to the cloud for processing. Instead, 4 5'
