Feature: Communications
Other SoC examples for such
applications come from NXP: the Layerscape family is well-suited for the protocol stack and access to the PHY. For example, the LX2160A multicore processor, the highest-performance member of the Layerscape family, includes sixteen Arm Cortex-A72 cores, as well as features that make it ideal for 5G packet processing applications.
Transport applications Public transportation has become an increasingly important market for wireless communications. LTE can provide connectivity between the Internet and moving vehicles such as aircraſt , trains, subways and buses. T e data connection can then be shared between passenger Wi-Fi and other functions such as fl eet management, driver/staff communication and security systems. T e ability to off er fast, dependable Wi-Fi to customers is a competitive advantage for transport operators, and can also provide another revenue stream. Wireless communication will also
become vital as we move toward more connected cars and, eventually, to fully- autonomous vehicles. For instance, in a pilot project in Germany, called InVerSiv, CommAgility’s eNodeB has provided robust and high-speed delivery of sensor data to a server and distribution of map data to mobile devices. As you’d expect, low latency is essential
for automotive applications, to maintain safety with fast responses. By customising
Building a private network with LTE involves developing a radio access network (RAN) that wirelessly connects base stations (often called small cells, access points or eNodeB) and mobile devices known as user equipment (UE)
the LTE eNodeB scheduler for delay- sensitive applications, and locating the eNodeB close to the Evolved Packet Core (EPC) soſt ware running on the server, these low-latency requirements are addressed.
Looking ahead T e next step beyond LTE is 5G wireless broadband. T is is already familiar, as it is being rolled out to consumers for their smartphones, but is now also starting to be used in private networks and similar applications. For specialised applications as discussed
here, there is still a need to customise 5G soſt ware to meet particular requirements, such as going beyond the speed or distance
supported in the 5G specifi cation. Compared with LTE, there are some
signifi cant technical improvements in 5G, for example more effi cient modulation. 5G also uses diff erent frequency bands, including new millimetre-wave bands above 6GHz. Taken together, this means that 5G can deliver higher bandwidth than LTE, at lower power consumption per bit. 5G also provides lower latency than LTE, so the response to new data or messages can be much faster. LTE provides an excellent solution
for private networks and transportation applications right now and will continue to do so for many years, while 5G provides another option and a path for future upgrades.
