5G must succeed indoors where 4G failed, and neutral hosts will be key

Despite the hype about 5G, many MNOs are clear that LTE still has considerable headroom, and a mature ecosystem. For many applications, including those requiring wide area coverage and affordable gigabit data rates, they will continue to enhance their 4G networks, adding new spectrum and smaller cells to boost capacity. However, there is one area in which 4G – or rather, the way MNOs have deployed it – has failed, and that is in deep indoor coverage. High quality indoor mobile signals remain elusive and in many industries, in-building coverage is scandalously low. This severely limits the extent to which enterprises can support basic applications like unbroken voice calls, let alone think about ultra-reliable IoT services or other 5G-class activities.…
