Different Types of 5G Technology 2024

5G wireless technology has continued to advance and expand since the initial rollout in 2019. As we enter 2024, there are several key types of 5G networks that have been deployed or are in development. In this article, we’ll provide an overview of the most important 5G technology types and what makes each one unique.

1. Sub-6 GHz 5G

Sub-6 GHz 5G refers to 5G networks that operate on frequency bands below 6 GHz, typically in the 3-5 GHz range. This type of 5G offers a good balance of coverage and capacity, making it well-suited for widespread initial deployment. Key advantages of Sub-6 5G include:

  • Broader coverage area – Sub-6 signals propagate farther than mmWave signals, enabling operators to provide 5G coverage to larger areas.
  • Penetration through walls/objects – Sub-6 GHz frequencies are better able to pass through obstacles like walls and trees compared to mmWave.
  • Easier mobility – Provides continuous 5G connectivity when moving in and out of coverage areas.

Some of the major wireless carriers like Verizon, AT&T and T-Mobile have utilized Sub-6 spectrum to rollout broad 5G coverage throughout many cities across the country. Speeds typically fall in the 100-500 Mbps range for Sub-6 networks.

2. mmWave 5G

mmWave 5G uses super high-frequency spectrum in the 24-40 GHz range (and higher) to enable ultra-fast data speeds measured in gigabits per second (Gbps). The tradeoff compared to Sub-6 is much shorter range and limited ability to penetrate obstacles. Key attributes include:

  • Extremely fast peak speeds – Current mmWave networks support up to 4 Gbps speeds with future potential for 10 Gbps+. Enables cutting-edge applications.
  • High capacity – mmWave spectrum opening up a much wider lane for data traffic compared to older cellular bands.
  • Low latency – Response times of just a few milliseconds, enabling innovations for real-time control and interactivity.

To date, mmWave deployments have been small scale and limited to major city centers or sports stadiums where high capacity zones can provide targeted coverage. But in 2024 and beyond, scaling up mmWave to wider areas is an active area of development to unlock the full potential of multi-Gbps 5G connectivity.

3. Low Band 5G

Low band 5G leverages frequency bands below 1 GHz, including 600-700 MHz spectrum, to provide control, connection density, and coverage over very wide areas – especially rural locations. Key features include:

  • Long range propagation – Low band signals travel much farther across open spaces than higher 5G frequencies.
  • In-building/underground penetration – 600-700 MHz spectrum can better reach challenging locations like basements.
  • Support for massive IoT – Enables large scale 5G connectivity for sensors and smart devices.

The compromise is moderately lower peak data speeds compared to mmWave or Sub-6 GHz 5G. But low band’s long range and reliability are ideal for ubiquitous 5G in sparsely populated regions as well as IoT services.

4. Hybrid 5G

Most 5G network operators are pursuing a hybrid approach that utilizes a mix of Sub-6 GHz, mmWave and low band spectrum. Each frequency range serves a specific purpose – Sub-6 for widespread coverage, mmWave for high capacity zones, and low band for extended reach. Key aspects:

  • Nationwide coverage – Broad 5G access across all locations by combining different spectrums.
  • Speed and capacity flexibility – Adjust network architecture based on local speed/capacity demand.
  • Supports all usage models – Enables wide range of consumer and industrial 5G use cases via one integrated platform.

Big wireless carriers are aggressively driving hybrid 5G so they can provide a tiered set of 5G service capabilities adapted to different geographic areas and applications requirements.

5. Standalone 5G

The initial rollout of 5G from wireless carriers utilizes a non-standalone architecture that relies on integration with existing 4G LTE networks for key control functions. By contrast, standalone 5G features:

  • Independent operation – Standalone 5G networks handle all communication and computing functions natively within the 5G network.
  • Advanced capabilities – Supports cutting-edge 5G features like network slicing and ultra-reliable low latency not fully available on non-standalone networks.
  • Simplified infrastructure – Avoiding interaction complexity with 4G core may provide opportunity to optimize next-gen infrastructure for 5G efficiency.

Many carriers worldwide have aggressive timelines to deploy standalone 5G architecture by 2024 to realize the full technology potential. The transition is enabled by upgrades to the core network and software functions.

6. Private 5G Networks

Private 5G networks provide dedicated local 5G connectivity under the control of a specific enterprise or industry. This contrasts with public 5G coverage from consumer wireless carriers. Key private 5G attributes:

  • Customized for vertical needs – Tailor network capabilities around specialized performance, security and capacity demands.
  • Local control – On-site private 5G puts real-time connectivity firmly in hands of enterprise or site owners.
  • Potential for edge computing – Enable low latency services by integrating computing power at the local edge of private networks.

Private 5G early movers include manufacturing facilities, ports/shipping, oil/gas sites, smart venues like stadiums, and automated robotics applications. In 2024 and beyond, private network functionality may merge with public 5G services.

7. Integrated Access & Backhaul

An emerging 5G networking architecture called IAB (integrated access & backhaul) features consolidated connectivity between the radio edge and core network. Innovations include:

  • Efficient mid-band backhaul – IAB allows flexible mesh backhaul topologies utilizing mid-band 5G spectrum already present at access sites.
  • Cost and complexity reduction – Converging distinct access and backhaul links provides opportunity to lower expenses.
  • Extended coverage – Multi-hop mesh architecture stretches 5G signal reach further than traditional single-hop backhaul.

IAB remains an emerging concept today with upcoming commercial trials planned through 2024 and beyond. It promises a path to streamlining expansive 5G infrastructure for ubiquitous next-gen connectivity.

8. AI-Enabled 5G

AI-enabled 5G leverages artificial intelligence and machine learning techniques to actively optimize performance across 5G networks. Major impact areas:

  • Predictive user mobility – AI anticipates locations/movements so networks proactively adapt for continuous high speed service.
  • Dynamic spectrum allocation – ML algorithms assign spectrum resources in real-time based on application demands to maximize 5G efficiency.
  • Proactive congestion mitigation – Identify potential congestion points ahead of time and steer capacity to where its needed most.
  • Automated infrastructure management – Take human operators out of many real-time decision processes for increased reliability.

With rising 5G complexity, agile and often cloud-based management layers will become increasingly crucial for carriers worldwide throughout the 2020s.

10. Network Slicing

Network slicing allows operators to create multiple virtual partitions within a common 5G infrastructure that act as independent networks tailored to specific applications or services. Custom slices can offer:

  • Guaranteed user/traffic separation – Unique security, capacity and functionality for each distinct slice.
  • Precise performance controlFine tune latency, throughput, reliability and other capabilities based on use case requirements.
  • Maximized asset utilization – Slice common infrastructure into a wide array of services for disparate clients.

11. Multi-Access Edge Computing

Multi-access edge computing (MEC) is an important 5G concept that pushes compute/storage resources to the extreme edge of networks. Key benefits:

  • Ultra-low latency – Run applications directly at the 5G edge to enable real-time responsiveness.
  • Location/context awareness – Edge presence combined with network APIs give apps access to valuable insights about end users and attached IoT systems.
  • Enhanced performance – Edge nodes alleviate backhaul bottlenecks and allow caching popular content closer to end users.

Over 2024-2025, MEC deployment is expected to accelerate in tandem with 5G standalone core network rollouts. This will support new edge-based 5G applications.
