This 4x2 configuration isn't the only one possible, however, upgraded cell towers can have many more transmit/receive antenna elements. In this case, 4x2 means four transmit/receive antennas on the tower, and two on the user device: A basic 4G/TE network 4x2 deployment - with 4 antennas on the cell tower and 2 in the mobile device working together. This figure illustrates a relatively simple 4x2 MIMO deployment. These antennas connect to a cell tower that will usually have at least four antennas - and as many as 128! The number of antennas on the tower gives devices more options to get a good, high-performing connection. #Lte antenna booster pro#This allows those devices to utilize 2x2 MIMO.ĭevices with four antennas for 4x4 MIMO is now common, with consumer devices such as flagship hotspots (the AT&T Netgear Nighthawk M6 Pro Hotspot Pro, the Verizon MiFi Orbic Speed 5G UW, the T-Mobile Inseego 5G MiFi M2000), and many newer smartphones like the iPhone 13.Īlthough the latest cellular standards (Category 18 & higher) support 8x8 MIMO, consumer devices with 8 antennas are not common. The cell tower will have a number of transmit/receive antennas and most LTE devices will have two antennas. The ability to make multiple connections on the cell tower the better the transmit speeds, even with weak signals. With more antennas transmitting a signal, there are more possible echoes and reflections (read the "how it works" section below to understand the magic here) for the receiving device to catch a signal. On the other end of the line - cell towers typically have multiple antennas working together in tight synchronization to communicate with you. MIMO is one of the core technologies enabling 4G/LTE and 5G cellular, and almost every modern mobile device (whether a phone or a hotspot) has two or more cellular antennas on board to enable the magic of MIMO. Read on to get a grasp of what MIMO is, how it works, and how you can use a little bit of MIMO awareness to potentially increase your cellular speeds. MIMO technology is fundamental to both 4G/LTE, 5G, and WI-Fi radios - but cellular boosters and MIMO have some. One of the key technologies making these sorts of speeds possible is known as MIMO (Multiple Input, Multiple Output) - an incredibly clever technique for putting multiple antennas to work to increase both data transmission speed and reliability. 5G, for now, isn't much better than LTE unless you're on the super-short-range millimeter-wave network, but that will change over time as 5G network capabilities are expanded. An early MIMO antenna prototype?īut real-world 4G/LTE speeds over 50Mbps are actually not at all uncommon, and speeds over 100Mbps are now widely reported - and things just keep getting faster. Of course, theory rarely equals reality - and the cellular networks need to be substantially upgraded and built out to even come close to being able to deliver speeds like this to real people outside of a lab.Īnd in the real world - you will be sharing this speed with perhaps hundreds or thousands of others connected to the same cell tower. For RVers and Cruisers, understanding what MIMO technology is, how it works, and how it can be used to enhance cellular speeds has the potential to make finding great mobile internet on the road an easier experience.įor anyone who knows a thing or two about wireless communications, modern 4G/LTE and 5G cellular radios are borderline miraculous.Ĭonsider the first iPhone - which launched in 2007 with a maximum theoretical cellular speed of around 500 Kbps using AT&T's 2G EDGE cellular network.Ī decade and a half later - the latest flagship cellular devices were able to support maximum theoretical speeds of over 2,000 Mbps.Īnd as we head into the 5G era, peak theoretical speeds are approaching 10 Gbps, another 10x increase!
