How can 5G cell phone signal boosters help with speed and connectivity ?

Before we can understand how the 5G we need to understand how 5g works.

• Resources should be be shared between the LTE and NR and what is the goal from DSS?
Resources will be dynamically assigned based on traffic conditions.
• What is the main goal and motivation for using 4G DSS?
I. The Main goal is wide area coverage.
II. Current NR frequencies are in mid and high bands which are important for capacity.
III. Lower operating bands be used, and those bands are currently occupied by LTE.
• What do LTE and NR Need to boost performance and work together?
LTE and NR systems need to be synchronized in both time and frequency domain. When using 15
kHz sub-carrier spacing for NR, both technologies can operate on a common time/frequency grid.
NR can also operate in a 30 kHz spacing.
• Is DSS Visible to LTE only Devices?
DSS is transparent to LTE devices This means NR must operate around LTE’s “Always On” signals
such as the cell specific reference signal

5G nomenclature

  1. 5G – A name for a collection of new services that will be offered by network operators using a variety of technical means.
  2. 5GNR – the name for one of the new technologies used to implement 5G. Specifically, it refers to the make-up of the actual signal that goes between a 5G phone and the base station.
  3. 5G mm WAVE – the name of one of the new technologies used to implement 5G. Specifically, it refers to using very high frequencies (12GHz or 23GHz or even higher) between a phone and the base station. These signal don’t propagate well but can support very fast data rates.
  4. 5G sub-6GHz – the name of one of the new technologies used to implement 5G. Specifically, it refers to using frequencies below 6GHz between the phone and the base station. These signals propagate better than mm WAVE signals and provide greater coverage areas.
  5. 5G-DSS – Dynamic Spectrum Sharing (DSS) is a technology that is used by network operators to share their spectrum between 4G LTE services and 5G services, in a single hybrid channel.
  6. NSA – Non-standalone mode (NSA) of operation means that in order for 5G signals to be received on your phone, your phone must also be connected to a 4G LTE signal. The way you can think about this is that the network uses the 4G LTE signal to tell your phone how to access the 5G signals.
  7. SA – Standalone mode (SA) of operation means your phone can directly connect to a 5G network, just like it connects to LTE network today.
  8. MBSFN – Multi-band Single Frequency Network (MSFN) is a technique used by LTE networks to create space for special services to be sent from a base station to a phone. This space can be used to deliver broadcast content for example or can be used to send 5G signals to a phone. One option an operator has is to create space in the LTE network for 5G using a MBSFN configuration, and then filling that space with 5G signals creating a 5G-DSS system.
  9. Non-MBSFN – a different technique to share the spectrum between 4G LTE and 5G, but the results is the same – a 5G DSS system.
