Treatment will be brought to the patients and patient data will be centralized, \u201cturning hospitals into data centers,\u201d a telco equipment maker says in a recent report.\nEricsson, in its 2017 Mobility report (PDF), published this month, says patient treatment will, in the future, no longer be performed in hospitals located far from patients\u2019 homes, but performed remotely through new 5G wireless radio.\n+ Also on Network World:\u00a0Reliability, not principally speed, will drive 5G +\nWearables will be among the tools used for keeping an eye on folks\u2019 health and dishing out medication. Diagnosis will be accomplished through online consultations, and robots will remotely execute surgeries at nearby healthcare clinics rather than far-off hospitals.\nEricsson is a mobile technology company actively involved in 5G wireless development, which it\u2019s pitching at Internet of Things (IoT) uses. It says IoT devices in general will increase at a Compound Annual Growth Rate (CAGR) of 21 percent between 2016 and 2022 and that there will be 1.5 billion cellular IoT devices by 2022. That\u2019s partly because of 5G.\nThis vision of decentralized healthcare is an example of something that could be driven by next-generation wireless networks, the company pitches in its report. A good thing: Patients are demoralized by the costs and inconvenience of medical attention, Ericsson points out, yet hospitals need to reduce costs.\n5G devices, with low power consumption of possibly up-to-10-years battery life, along with new-found, low-latency that is expected to become possible with the millimeter frequencies in the spectrum used, could deliver haptic feedback. That might be good enough to supply a sense of close-to real-time touch for surgeries. 5G latency rates could be a single millisecond\u2014compared to 4G LTE\u2019s 50 milliseconds, Ericsson explains.\nAdditionally, 5G, with its possibly fresh approach to security, might be more watertight than existing communications channels and thus better suited to healthcare.\n5G\u2019s rollout, coming commercially as early as 2020, is \u201cdue to provide 10 to 100 times more capacity than 4G,\u201d according to Ericsson. Interestingly, though, the 5G tech could encounter trouble, according to a consultant.\nA bump in the road to 5G\nIt isn\u2019t all about wireless, consultant Deloitte says. For 5G to achieve its suggested blockbuster status the U.S. must invest in fiber, of which there isn't enough..\n\u201cThe success of 5G wireless will hinge on deep fiber,\u201d the company says in a press release.\nNetworks in the U.S. don\u2019t have the \u201cfiber density\u201d to cope with the bandwidth demands of future 5G applications, Deloitte says.\u00a0One issue is that the nature of shorter-distance millimeter spectrum is that it needs more cell sites. They need connecting.\n\u201cWithout more deep fiber, carriers will be unable to support the projected four-times increase in mobile data traffic between 2016 and 2021,\u201d Deloitte says.\n(Ericsson\u2019s latest projection is a 33 percent compound annual growth rate for U.S. mobile data between 2016 and 2022).\nIt will take \u201can investment of $130 billion to $150 billion in fiber infrastructure over the next five to seven years to adequately support broadband competition, rural coverage, and wireless densification [needed for 5G],\u201d Deloitte says.\nSo, 5G might not be as simple as the pre-marketing rhetoric suggests. Someone has to come up with, and pay for, more underlying network, Deloitte says.
