<p>5G networks will be used with much smaller cell sites. Higher frequency radio waves are only capable of travelling short distances as compared to the lower frequency 4G LTE waves. Since the 5G signal can only be transmitted about the distance of a city block and cannot permeate buildings, there will be less need for large network towers and more need for small cell towers approximately every city block as well as within buildings. This also means that the speed on the individual networks will be greater than before.</p><p class="inline">An article written by professors from the University of Waterloo, Carleton and Ozyegin Universities explains that 5G networks could completely transform the current cellular architecture. They explain that for 5G to function with such a high demand for network bandwidth from IoT devices, the traditional cellular architecture may be divided into a two-tier architecture: 1) a macrocell layer, for base station-to-device communication, and 2) a device layer, for device-to-device (D2D) communication.</p> <p class="expand inline mw-collapsible-content">. However, this poses risks for security. D2D communication requires more complex network security than what is currently available. Communication is possible through the use of device relaying; connected devices use one another to retransmit data, creating an ad hoc mesh network. In this way, the devices can communicate with one another in a licensed cellular bandwidth without the use of a base station (BS).

   <p class="inline">Previously, D2D communication has only been used minimally. Recently, demand for this capability has grown as more context-aware applications come to market. These applications generally require both location services and the ability to communicate with other devices. Providing this capability through D2D would offer cost savings since not all devices on the network would need to be connected through the BS. D2D could also play a role in mobile cloud computing and enable more effective sharing of resources. If a device is at the edge of a cell site or in a crowded area, D2D could eliminate a significant resource burden on the BS.</p>
