Market forecasts predict the IoT device industry to exceed $40 billion by 2030, with a significant share of that growth expected in cellular IoT (5G). For modern organizations, IoT deployment is not enough; they also require uninterrupted connectivity between devices. For healthcare, supply chain assets, utility grids, analytics, and more, multi-network cellular IoT is an essential solution to modern data management issues.
Businesses need the right tools to make real-time decisions even in shifting regulatory environments. This article explains the benefits of finding multiple carriers to manage organizational IoT frameworks. These tips provide a network approach that allows them to easily change course based on real-time data coordination across the entire network.
What Are Multi-Network IoT Devices?
Multi-network IoT devices are equipped with SIMs that can use multiple carrier networks to transmit data. Traditional IoT relies on one mobile operator, but a multi-network approach allows the system to switch carriers based on the requirements of the transmission and the current network status.
IoT devices that can access multiple networks are more dynamic than those with a single provider. Using pre-configured signal conditions, they provide real-time information exchange between multiple worksites or within an environment where single carriers would experience connectivity issues.
Common use cases for multi-network cellular IoT include:
- Operations with dispersed geography, such as vehicle fleets
- Operations with high-uptime requirements, such as medical care
- Operations in challenging connectivity environments, such as energy and agriculture
The usefulness of the network depends on three essential factors of multi-network IoT: consistent uptime, high load balancing, and reliable failover.
What Is Carrier Aggregation?
Carrier aggregation typically combines multiple frequencies within a single carrier’s spectrum, improving bandwidth and reducing latency. This differs from carrier switching, which, as the name suggests, switches between multiple carriers. While these processes sound similar, they achieve very different purposes.
Carriers aggregate their signal to boost speed and bandwidth by utilizing multiple bands from the same network. However, carrier switching is done to help ensure device uptime and failover while providing broader coverage. Put another way, aggregation prioritizes performance and throughput while switching prioritizes reliability and coverage.
Benefits Of Multi-Carrier Support
To summarize the essentials of multi-network IoT adoption, consider these strategic advantages that organizations can achieve:
- Better coverage in rural areas
- Higher uptime and lower service disruptions
- Better global deployments without regional provisioning
- Faster performance
- Improved ROI on network investments
These ideal benefits can only be achieved when technology leaders know how to match the network carrier to the organization’s specific needs.
Key Components & Features
Multi-network IoT devices do not operate through guesswork, and neither should IT directors. As the systems rely on internal rules, recognizing how the system operates can help organizations choose the best network for their needs.
1. Signal Strength & Quality Assessment
The first step to choosing the right IoT network is to compare its signal strength to the organization’s network requirements. This involves measuring RSSI, or Received Signal Strength Indicator, to examine how strong the signal is. However, strength is not the only measure of signal quality. Considering other metrics, such as RSRQ, SINR, and RSRP, can help organizations make sure their on-network devices connect more seamlessly by avoiding crowded grids.
2. Network Availability Checks
Multi-network devices work by keeping a list of pre-approved carriers and scanning for available networks in that list. This requires several individual checks to make sure the network is reliable, including:
- SIM profile
- Roaming and access rules
- Device registration restrictions
Carriers that fail one or more of these checks will be de-prioritized as the system searches for an alternative to maximize connectivity.
3. Network Selection Algorithms
Many organizations focus on the signal when choosing a carrier, but the selection algorithm is another important consideration. The device logic that chooses the best available network accounts for the priority settings, load balancing, failover rules, and time-based network activity to choose the carrier with the best conditions at the time the task needs to be carried out.
Factors Influencing Carrier Selection
Multi-carrier IoT networks help organizations adapt to dynamic data environments, provided they account for key transmission factors, such as:
- Geography: Carrier coverage differs depending on the terrain and region. While cities can often maintain consistent coverage more easily, rural areas deal with large performance disparities.
- Congestion: No matter how strong the signal, carrier towers can become congested with data transmissions. Adaptive multi-network devices can examine networks for signal activity and switch to less congested carriers to maintain signal quality.
- Load Spikes: In addition to assessing network congestion, multi-network platforms can analyze time-of-day usage trends and adjust network preferences accordingly.
Optimizing Multi-Carrier Performance
Optimizing multi-carrier performance requires not only the right choice of carrier and a strong, high-quality signal but also the right configuration and monitoring strategy. This includes:
Setting and monitoring minimum signal quality thresholds- Whitelisting trusted networks and blacklisting problematic ones
- Leveraging multi-IMSI profiles
- Avoiding bouncing with smart failover logic
- Using IoT connectivity platforms to track signal trends, network issues, and downtime
- Generating alerts for anomalous network behavior
- Logging historical performance data to improve decision-making
A trusted IoT device carrier can help organizations implement a multi-network IoT strategy that ticks all the right boxes, even in a competitive data environment.
