Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases capacity and speed using a different radio interface together with core network improvements.
Fifth generation (5G) performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. 5G succeeds 4G and 2G (GSM) systems.
Narrowband IoT (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard developed to enable a wide range of cellular devices and services. NB-IoT focuses specifically on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band.
LTE category 1 (CAT-1) sits between the high-speed LTE categories that are most commonly seen in smartphones and the low speed LTE categories developed specifically for Internet of Things (IoT) and Machine-to-Machine (M2M) applications. It is the lowest cost LTE category that still has the required speeds to support data streaming.
VoLTE stands for voice over LTE, which is essentially voice calls over a 4G LTE network. Voice traffic over VoLTE frees up spectrum and allows it to be used for other purposes.
Multiple-input and multiple-output (MIMO) is a method for multiplying the capacity of a radio link using multiple transmit and receive antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards.
Carrier Aggregation is an advanced technology that bonds multiple spectrum channels together.
4X4 MIMO (Multiple Input Multiple Output) is a technology that delivers twice the speed and incremental network capacity to a wireless device by doubling the number of data paths between the cell site and the wireless device.
Full Dimension MIMO (FD-MIMO) is LTE technology utilized in the evolution to 5G.
256 QAM (Quadrature Amplitude Modulation) increases the number of bits delivered per transmission to enable faster speeds.
License Assisted Access is a technology that utilizes unused, unlicensed 5GHz spectrum to augment available bandwidth. This technology provides a huge speed and capacity boost for heavily un-utilized outdoor spectrums across the US.
