In addition, femtocells only support a limited number of users and have a far limited range than microcells and picocells – often around 10 metres. They are pitched as an easy to way to improve indoor coverage at home or in the office, although recent developments such as Voice-over-Wi-Fi (VoWi-Fi), which allow users to make and receive calls on their smartphone over a local wireless network, may have reduced their appeal. Whereas operators are responsible for the deployment, maintenance and performance of microcells, femtocells are installed and run by an individual user or business. Femtocellsįemtocells are another type of microinfrastructure with a crucial difference. This might mean complicated or lengthy negotiations with the landowner or through a public authority. There must be an appropriate power source and operators must have physical access to the site. Operators must ensure they have backhaul – either fibre or wireless – at the site. Some of the limitations that apply to macroinfrastructure also apply to microcells. Microcells help satisfy these requirements. For example, a smart city application might involve hundreds of devices feeding back to the network, while a connected car will need reliable connectivity as it moves around a city. The additional capacity afforded by microinfrastructure is essential for 5G-enabled machine applications – especially those enabled by ultra-high spectrum. This means the user gets seamless connectivity, better speeds and possibly even better battery life because they are connecting to a closer cell.īut it’s not just smartphone users that benefit. This means the microcells can support a user as they move around and ensure the local macro network isn’t swamped by the additional demand. This means operators will need to deploy multiple microcells in the desired coverage area. Additionally the number of users might exceed the capacity of the microcell. Mobile operators can then provide additional capacity to cover a large number of users in a crowded area – such as a public square, shopping centre or football stadium.Ī range of up to 2km is possible, however if the microcell is using high range spectrum such as mmWave, the reality is that buildings and other objects will block the signal. Microcells don’t take up much space so can be affixed to street furniture such as lampposts, bus shelters or the side of a building. Microcells are essentially small masts that can be affixed to existing physical infrastructure in areas where it’s impractical to install a full-size mobile tower or even more standard mobile antennas that are found on rooftops of tall buildings. There are three types of microinfrastructure that will help assist with this densification, each of which has different advantages and disadvantages – microcells, femtocells and picocells. Microinfrastructure will play a critical role in densifying the network so that devices and applications that require a constant connection can be supported, and so that smartphones in busy, heavily populated urban areas can maintain a signal no matter how many people are around them and where they travel. That’s before you consider the expense of maintenance and the tower’s power requirements.ĥG networks are instead looking at microinfrastructure – compact antennas that are deployed alongside traditional macroinfrastructure. 5G towers take up a significant amount of space that cannot be found in a major city like London or New York, and even if authorities could identify a location, the height of the mast would be unsightly and would likely fall foul of local planning laws. Traditional masts are not suitable for such a task. As a result, operators will have to densify their networks to maintain reliability. However high range spectrum has low range and poor propagation qualities that make it a challenge to provide coverage – especially in urban areas. The millimeter (mmWave) spectrum covers higher frequencies than current 4G technology. ![]()
