5G (NR) = The 5th Generation New Radio
What is 5G (NR)? Exponential growth in network traffic, new use cases and shared spectrum resources have placed a tremendous pressure on MNOs to find the most efficient use of their allocated radio spectrum. There is a need for a New Radio evolution to improve spectral efficiency and superior network capacity. This evolution starts with 5G NR (New Radio) which is the new standard for 5G wireless technology capable of a much faster, efficient and scalable network. Associated with the new standards being developed for 5G RAN by the 3GPP. 5G (NR) delivers high levels of capabilities to the network by increasing the spectrum efficiency, traffic capacity, throughput, reliability, number of connected devices and reducing end-to-end latency.
5G = The 5th Generation
What is 5G? The next telecom standards operating in the millimeter wave bands (28, 38, and 60 GHz); 5G planning aims at a higher capacity than current 4G, allowing a higher density of mobile broadband users, and supporting device-to-device, more reliable, and massive machine communications. The fundamental appeal of 5G lies in the fact that the entire infrastructure acts as a cohesive platform for innovative applications and is tuned to flex with demand - providing services tailored to their unique characteristics. While the infrastructure may encompass discrete components from multiple vendors and heterogeneous wireless networks, it is designed to be a fully programmable and an interoperable framework both in the core and radio resource management.
A2P = Application to Person
What is A2P? Featured in our MaaP solution, A2P generally refers to functionality that allows an application (e.g., a web app) to send a message to one, or many simultaneous, mobile phones. Common use cases of A2P are alerts, notification, and branded marketing messages, such as flight alerts. In all the cases, communication is initiated from a business application, and not an individual’s mobile phone, as is the case with P2P SMS.
AI = Artificial Intelligence
What is AI? Artificial Intelligence is the development of computer systems that mimic cognitive learning and problem-solving functions associated with human mind. Artificial Intelligence and Machine Learning can be leveraged to manage large amounts of data using algorithms and heuristic learning abilities. These tools power Mavenir’s world-leading messaging SIM-box, grey-route and fraud detection capabilities. 
BBU = A Baseband Unit
What is BBU? A baseband unit (BBU) is a unit that processes baseband in telecom systems. A typical wireless telecom station consists of the baseband processing unit and the RF processing unit (remote radio unit - RRU). The baseband unit is placed in the equipment room and connected with RRU via optical fiber. The BBU is responsible for communication through the physical interface. A BBU has the following characteristics: modular design, small size, low power consumption and can be easily deployed. Virtualized RAN offers a strategic differentiation by enabling the RRUs to interwork with the virtualized Cloud BBU over a non-ideal fronthaul (i.e. ethernet), overcoming the traditional constraints of CPRI over fiber.
C-RAN = Centralized Radio Access Network
What is C-RAN? The acronym C-RAN, for “Centralized RAN” is sometimes mistakenly defined as Cloud RAN, but it actually refers to a centralized, cloud-computing-based architecture for radio access networks that supports 2G, 3G, 4G, and future telecommunication standards. It is an architecture which enables radios and antennas to be deployed close to the end user without the expense of a base station onsite. The Base station equipment can be located in a less expensive location and connected to the radios with fiber, allowing network capacity to be allocated dynamically.
CA = Carrier Aggregation technology
What is CA? Carrier Aggregation is a technology to combine two or more carriers into one data channel to enhance the data capacity. It is possible to combine carriers in the same or different frequency bands. The easiest way to aggregate carriers is to take two or more contiguous channels within the same frequency band (intra-band, contiguous). It is also possible to combine two or more non-contiguous channels within the same band (intra-band, non-contiguous). The most challenging form is to aggregate two or more carriers from different frequency bands (intra-band; non-contiguous). Carrier aggregation technology is implemented in most modern mobile communication systems, like LTE and WiMax.
capex = the Capital Expenditure
What is capex? The money a company spends to buy, maintain or improve its fixed assets, such as buildings and equipment. This word is commonly capitalized like an acronym, but it is now a word in its own right. Capital expenditures contrast with operating expenses (opex), which are ongoing expenses that are inherent to the operation of the asset. Opex includes items like electricity or cleaning. The difference between opex and capex may not be immediately obvious for some expenses; for instance, repaving the parking lot may be thought of inherent to the operation of a shopping mall. The dividing line for items like these is that the expense is considered capex if the financial benefit of the expenditure extends beyond the current fiscal year. Download our White Paper on how with a Virtualized RAN Deployment, Mobile Operators Can See 49% Savings in capex and 31% Annual Savings in opex.
CCaaS = Contact Center as-a-Service

COTS can be obtained and operated at a lower cost over in-house development, and provide increased reliability and quality over custom-built software. Commonly used in Mavenir's 4G and 5G Solutions.

CUPS = Control and User Plane Separation

What is CUPS? Essential to 5G networks, CUPS reduces latency on application service, e.g. by selecting User plane nodes which are closer to the RAN or more appropriate for the intended UE usage type without increasing the number of control plane nodes. Also, CUPS supports an increase of data traffic, by enabling to add user plane nodes without changing the number of SGW-C, PGW-C, and TDF-C in the network.

What is Small Cell (or Femto Cell)? Small cells are low-powered cellular radio access nodes that operate in a licensed and unlicensed spectrum that have a range of 10 meters to a few kilometers. They are "small" compared to a mobile macrocell, partly because they have a shorter range and partly because they typically handle fewer concurrent calls or sessions. They make the best use of available spectrum by re-using the same frequencies many times within a geographical area. Fewer new macrocell sites are being built, with larger numbers of small cells recognized as an important method of increasing cellular network capacity, quality and resilience. As an MEC application, Private LTE is considered a small cell. = Small Cell = low-powered cellular radio access nodesSmall cells
