Private LTE / 5g

Bridging Private LTE/5G and Wi-Fi

A critical issue that has been deliberated and debated for years now has been how technologies like MultiFire, LAA and CBRS would reduce the need for Wi-Fi networks and possibly eliminate the need for Wi-Fi altogether.  This idea that suggests Wi-Fi is on its deathbed with the advancements made in private cellular use is, flawed. 

With each advancement that we collectively experience in licensed RF spectrum use, unlicensed spectrum advances at the same rate.  Be it chipsets, modulation techniques, security and more – for every advancement that lowers the cost per bit and the efficacy of a licensed network the same is true for unlicensed technologies.  Thus the question is not if Wi-Fi has a place or Private LTE has a place as much as how do we best design and deploy RF networks in a way that creates cost and operational efficiencies. 

Ultimately, both licensed and unlicensed RF technologies and protocols are transport layer protocols.  As such, they should and can be used in parallel to one another or in support of one another.

Consider K-12 remote learning initiatives.  School districts have a need to ensure that their students have access to Internet for things as simple as keeping up with school work or as critical as attending school remotely during periods shutdown like we have seen during Covid-19 lock-downs. 

We have seen several larger school districts already deploy Private LTE to extend the reach of the campus to the home of students but the very last piece of connectivity from the CPE is still Wi-Fi.  The CPE is actually a modem with a 3.5ghz WAN connection and 2.4/5Ghz LAN connection in the home as a separate overlay to the school network.  With the rXg as a head-end to both the private LTE/5G network and Wi-Fi network, the same RBAC tools can be used to extend each function afforded in the classrooom to the school supplied home network. 

Of course, these use cases exist beyond K-12 and fit well in manufacturing where the determination should be what traffic type should be routed over which L1.  For example if you consider a manufacturing facility that relies on robotics, UAV or programmable automation leveraging 3.5Ghz which is less prone to interference and routing less latency sensitive traffic over Wi-Fi maximizes function and cost simultaneously. 

With rXg you can:
  • Route based on applications and functions to maximize cost-per-bit
  • Ultra-scalable DDI capable of supporting hundreds of DHCP requests per second and thousands of DNS requests per second
  • Automatically equalized and fair share hierarchical per-user / device / group / policy traffic shaping 
  • Ultra scalable micro-segmentation and device aware network admission control (NAC) system
  • Improve frame delivery efficiency, improving network capacity and throughput
  • Efficiently leverage existing NAC and security policy over disparate infrastructure

The breadth of credential possibilities available in the rXg enabled the IT staff at The International Centre to support the full spectrum of use cases of Internet purchase use cases from wholesale facility or single hall buyout to retail purchase by an individual attendee as well as everything in between.
