![]() ![]() CRAN was the first RAN to use cloud computing and IT infrastructure to provide cellular improved cellular coverage, capacity, and reliability. Notably CRAN also uses real-time visualization to allocate shared resources dynamically, and support multi-vendor environments. ![]() CRANs take advantage of different types of new technologies like the CPRI standard, which gives CRANs the ability to transmit over long distances reliably from a centralized tower deployment. Sometimes referred to as Cloud-RAN, this type of RAN architecture uses cloud computing as the core of its network and data processing for cellular signals. This form of RAN also began to use ODFMA digital modulation which dramatically helped reduce interference. This RAN was the next evolution of UTRAN that rolled out a new air interface system that could provide better data rates, lower latency, but most importantly was optimized for packet data. The technology behind UMTS RANs are more commonly known as 3G to the public, and was the first form of RAN to make the first generation of smartphones possible. The network consists of base stations and Radio Network Controllers which take the signal of a cellular device and process into the core network. This is a form of RAN that is responsible for connecting user equipment (UE) to the core network. UTRAN: UMTS Terrestrial Radio Access Network EDGE technology was first used on GSM networks in 2003, and delivers three times the capacity and performance compared to GSM/GPRS alone. This network standard uses the Enhanced Data Rates for GSM Evolution (EDGE) cellular technology that helps improve data transmission, and acts as a backwards compatible addition to standard GSM. After first being deployed in the late 1990s, it quickly became a global standard by 2010 with the mass adoption of 2G technologies. Global System for Mobile Communications (GSM) is one of the earliest technologies seen in RANs, and was first introduced for protocols in the second-generation 2G cellular networks. There are also a few other types, such as CRAN, VRAN, and ORAN. There are many different types of radio networks, mainly GRAN, GERAN, UTRAN, and E-UTRAN. Specifically, cell phones and other devices send and receive radio signals from the RAN network’s radio transceivers to connect to the core network. 4G LTE, 5G) devices back to a public and / or private mobile core network via an existing network backbone. Radio access networks are the part of a communications system that traditionally connects cellular wireless capable (eg. Looking for a complete explanation? Here’s what radio access networks (RANs) are, the different types of RAN, how RANs work, RAN architecture, RAN components, and the 5G future for Radio Access Networks. ![]()
