Press a button on a phone and there is a response. In today's 4G systems, latency is around 15 to 20 milliseconds (ms). The goal of 5G is to drive latency down to 5 ms. This is critical because 5 ms or less latency provides an experi- ence that feels innately real to the human body in vir- tual reality or simulations. Apple has coined the term "taptic" as an amalgama- tion of the words tap and haptic feedback to describe the components in its devices that provide a physical response to a user. It will only feel more real and natural with 5G, and these tactile systems will be found in a vari- ety of devices. Medical training programs utilizing virtual reality systems with taptic interfaces can be used by providers to practice medical techniques and role playing in a way that feels very real without any possible negative out- comes. Imagine a learning environment with a surgeon using a virtual reality mock-up to practice invasive surgi- cal cutting techniques; feedback is real and instantaneous, but without needing cadavers or live animals for practice. Virtual reality is also being developed for patient care. Patients might don a headset with visual displays that guide them through some form of therapy; embedded sensors in the headset measure heart rate, breathing, temperature, and other vitals while providing instanta- neous feedback and direction. 5G means much greater capabili- ties for healthcare devices. Other technologies that hold great promise for enabling medical systems include Citizens Broadband Radio System (CBRS). This system is an emerging wireless technology that will deliver better, faster wireless connectivity. The Citizens Broadband Radio Sys- tem, based on TD-LTE technology, will utilize a very large amount of spectrum (150 MHz in the 3.5 GHz space) and will be the first technol- ogy of its kind that allows dynamic spectrum sharing. This spectrum has been used primarily for naval radar, but it is only in use about 3 percent of the time. The Federal Communications Commission (FCC) wisely made plans to free up this spectrum for commercial use, provided there is a way to still allow prioritization. The spectrum access system (SAS) does just that. It manages the spectrum and the three classes of users: Incumbents (mainly naval radar), Priority Access (for organizations acting as CBRS service providers, up to 70 MHz of the 150 MHz) and General Authorized Access. The CBRS trials are already underway, and handset manufacturers will soon be deploying CBRS-ready handsets. Long-term evolution (LTE) is the wireless standard based on 3GGP. Unlike Wi-Fi, LTE is inherently secure due to encryption. This fact, coupled with the high-speed capabilities of CBRS and other LTE (cellular) 5G networks, has excited many in the IT community. The thinking goes: If I can get high (Wi-Fi like) speed on my handheld device, along with the best possible security, why would I not put all my devices on such a network? A tricorder was an object of science fiction lore that promised the ultimate in patient care and mobility for Trekkies; it was a handheld device that could perform a variety of medical diagnostics by sensing, computing and recording. That vision may soon become a reality.
