Reliable and secure wireless connectivity is an essential requirement for all industries. Nowadays, all types of communications, Human-to-Human (H2H), Human-to-Machine (H2M) and Machine-to-Machine (M2M) are needed. Some of which require centralized cloud processing; however, a lot of data has a local context.
The network must be capable of supporting various Quality-of-Service (QoS) profiles. Long communication data delays (latencies) may degrade the performance or quality of processes, or may even be prohibitive.
Strong security and privacy are major concerns for enterprises. For many enterprise applications, data exposure to the “cloud” cannot be tolerated.
Public mobile networks are frequently unable to fully meet the above-stated requirements.
The obvious alternative would be to build the local network using Short Range Device (SRD) technologies such as WLAN (WiFi). However, due to operation in unlicensed spectrum, i.e. shared frequency bands, these technologies cannot sufficiently support mission-critical industrial applications. Also, building radio coverage for a large industrial campus may require a high number of Access Points, thus will be expensive.
Private LTE, takes the best of both. Through relocating mobile data processing from the network core to the edge, Private LTE
