Boswell of Ericsson 2303GPP calls the coming release of 5G standards "Ultra-Reliable Low Latency Communication" (URLLC). However, key members of 3GPP strongly disagree. Jason S. Boswell, Ericsson's head of network security for North  America, cautions, "[5G] will create new mobile security challenges. There will be broader attack surfaces, more devices, and greater traffic."  

Primary 5G safety is not adequate. Instead, those needing certainty will have to pay extra for "tailored security solutions such as 'network slicing.'" These enhancements will be necessary, although not a guarantee. 

Boswell sees a problem. "We must have networks that are trustworthy, resilient, and secure by design – all on day one." Given that 50 million people are already connected to 5G that will be difficult.

The standards are not yet ready.

3GPP TSG RAN Chair, Balazs Bertenyi, expects 3GPP Release 16 to "freeze" in June and Release 17 not until December 2021. It typically takes a year or more for the standards to be available in tested equipment.

Hundreds of millions will have 5G before that's ready. 

Impractical dreamers run the 3GPP standards group, making promises that will be impossible to deliver. 5G was supposed to be 1 ms latency and 20 gigabits. The 5G shipping is off by an order of magnitude. It probably will take a decade for even 10% of 5G to come even close to that performance.
