5G comes with practical issues of limited range, necessitating a much greater quantity of microcells. These low power base stations themselves need either wired internet connectivity, or wireless backhaul connections. In order to deploy 5G to the public, more infrastructure is required. Complicating matters further for carriers, there is some public resistance to the installation of base stations.  Some dislike having them for aesthetic reasons, while others oppose them for based on health concerns. This has been an issue in the past, for earlier generations which utilized lower (further traveling) radio frequencies. In order to deploy 5G effectively, there must be many more localized base stations than were required by previous generations of the technology.

At the time of official release in 2019, 5G base station equipment was only available from China. Most notably, Huawei is a key provider of this equipment. Huawei came under attack not long before the release of 5G, for allegedly placing backdoors in their network routers on purpose.<ref>https://www.bloomberg.com/news/articles/2019-04-30/vodafone-found-hidden-backdoors-in-huawei-equipment</ref> However, Huawei claimed that this was nothing malicious, and that they had simply been using the telnet service during development, and had forgotten to remove it before sale. Regardless, the US began calling on its allies in the "Five Eyes" to ban Huawei's equipment for security reasons.<ref>https://www.theguardian.com/technology/2019/apr/30/alleged-huawei-router-backdoor-is-standard-networking-tool-says-firm</ref> Therefore, when the company released its 5G transceivers and related equipment, a number of western countries were very suspicious of how secure it really was.<br />
