Carriers building superfast 5G networks must install tons of small cell sites — about the size of pizza boxes — to light poles, walls or towers, often in relatively small proximity to one another. For that reason, superfast networks are mostly being deployed city by city. Eventually, most US carriers will have a mix of the different 5G network types (low band, mid-band, and high band) that will enable both broad coverage and fast speeds.
It is important to note that when new cell sites are installed or if cell sites need repair, carriers are already replacing them with 5G devices that do not service the older 2G and 3G networks. All Highland Park alarm customers have already migrated from the old 2G networks, but some of our customers with 3G/CDMA (Code Division Multiple Access) alarm radios are already experiencing degraded service (longer communication times, communications failures) due to cell site unavailability.
