Cellular technologies make mobile connections work—across phones, vehicles, buildings, and more. Every time someone loads a map or sends a message, cellular data is behind it.

Now, how does cellular technology do all this exactly?

What is cellular technology?

Cellular technology lets mobile devices connect wirelessly using a grid of local radio cells. Each cell is linked to a base station that handles voice, data, and text in a small area.

As people or devices move, they switch between nearby cells. This keeps the signal stable without losing signal or cutting off traffic. The design also allows many users to share the same airwaves.

You use this every time you send a text, stream a video, or get directions on your phone. But it’s not just phones—traffic systems, delivery trucks, and even smart buildings all rely on this grid.

Some of that local traffic—including building sensors and security systems—moves over CBRS data channels in private deployments. Meter delivers this as a managed network as a service, removing the need to run radios, buy licenses, or handle carrier coordination.

No extra SIMs or special plans needed.

Why cellular technologies are foundational to mobile communications

Cellular networks split regions into small zones, each covered by a base station. Devices connect to the nearest one and switch as needed based on signal strength.

Signals stay active while users move between zones, even in fast-moving cars or trains.

Frequency reuse lets operators serve more people without needing more spectrum. Non-adjacent zones use the same bands without interference.

Scalability works well in dense cities, open highways, and large buildings. Some enterprises use CBRS private LTE to build local networks in spaces where public coverage is unreliable.

What is a cellular network, and how does it work?

A cellular network is a system of radio cells that connect mobile devices to the internet and each other. Devices switch between nearby cells as they move, maintaining the connection across zones.

Coverage using “cells” with base stations

A cell is a small coverage zone. Inside each one, a base station connects to nearby devices using radio signals. The base station also links back to the core network using fiber or microwave.

Many of these zones work together to form a full mobile network. As someone moves, their device switches to the strongest nearby signal. That handoff keeps calls and data sessions active without interruption.

Meter uses the same principle indoors. Our Cellular Access Points let devices shift from the outdoor network to indoor coverage without any change to settings or user behavior.

Spectrum, signal handoff, and frequency reuse

Carriers use licensed spectrum to run their networks. Every operator gets access to a set of radio frequencies. Each cell uses specific channels from that pool to connect users.

To handle high demand, the same frequencies are reused in cells that aren’t next to each other. Careful spacing prevents signals from clashing. When a device moves between zones, it switches signals in real time. That’s the handoff process. It happens so fast that most users never notice.

Next, let’s consider the differences between the main types of cellular networks in this chart:

Public vs. private cellular network definitions

Public networks—like Verizon or T-Mobile—are open to anyone with a phone plan. They cover wide areas and follow national rules on licensing, privacy, and security.

Private networks are built by organizations. A factory, hospital, or research center might set one up for more control over traffic and coverage. CBRS is what allows enterprises to operate private LTE networks without buying exclusive spectrum rights.

Meter gives enterprises another option. We bring carrier-grade signal indoors without the overhead of running a private network. Teams stay connected using existing mobile plans and hardware.

No SIM swaps. No on-site network operations.

Types of cellular networks (2G to 5G and beyond)

Cellular networks have changed a lot since the 1980s. Each generation brought more speed, lower delays, and better support for mobile apps and devices. The focus shifted from basic voice to broadband data—and now to real-time communication.

Evolution from 1G to 5G (and what’s next):

• First, 1G used analog radio to support simple voice calls. Coverage was poor, and security didn’t exist.
• Next, 2G introduced digital voice and text. GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access) became the main global standards.
• Then 3G brought mobile internet. Early smartphones ran email, web, and lightweight apps.
• After that, 4G LTE made video, maps, and cloud apps practical with higher speed and stability.
• More recently, 5G NR unlocked low latency and high throughput for use cases like automation, robotics, and AR.
• Today, 6G is still experimental. Researchers are testing terahertz frequencies and AI-driven radio systems, but no standards exist yet.

Key innovations have shaped each generation with each set of new features. Initially, GSM defined how phones and towers communicate using digital channels. It shaped global roaming and SMS.

Then, CDMA packed more voice calls into each tower. It gained popularity in North America and parts of Asia.

Following that, LTE delivered broadband-like performance over cellular, making 4G the standard for video and modern mobile apps. To take it a step further, NR (New Radio) now supports 5G. It handles massive device counts, spectrum flexibility, and ultra-fast switching.

How each generation compares

The table below compares speeds, latency, and where each generation fits best:

Meter’s indoor LTE and 5G deployments focus on what matters most to enterprises: fast, low-latency connections that work where people actually sit, meet, and work. Instead of forcing teams to rely on weak indoor signals, we extend existing carrier networks into hard-to-reach zones.

Cellular network examples and use cases

Cellular networks support more than phone calls. They power machines, vehicles, and buildings where Wi-Fi or fixed lines don’t reach.

Mobile phones

Most people connect to cellular networks through phones. Billions of users depend on them for voice, text, and data every day.

As people move through cities or rural areas, phones switch between network cells to keep connections active. Telecom providers use this model to run large public networks across regions, borders, and continents. That scale is what makes phones feel reliable on the move.

Industrial IoT

Industrial environments use cellular networks to monitor sensors, control machines, and reduce downtime.

Machfu uses LTE and Cat-M with eSIMs to connect field equipment at oil and gas sites.

In remote mountain zones, power companies use 4G modems and edge computing to transmit live data during inspections. At factories, SmartTek Solutions combined mesh radios with cellular gateways to monitor operations across harsh and unpredictable spaces.

We often support this type of environment when clients need stable coverage across outdoor yards, utility corridors, or remote depots.

Connected vehicles

Cars, drones, and city transit systems depend on cellular networks for updates, control, and location services.

Volatus Aerospace uses eSIMs to connect drones around the world without switching carriers. In a pilot project, Ericsson ran remote-controlled buses over LTE in city traffic. V2X systems already rely on cellular signals to push traffic alerts and safety updates directly to cars.

Low-latency signal is key here. Without it, advanced automation features break down.

Enterprise environments need enhanced indoor coverage

Cellular networks often fail inside buildings. Concrete, glass, and steel stop outdoor signals at the wall.

Here are examples of how businesses have fixed these problems:

• Stanford Health Care fixed coverage gaps with a neutral host system. It improved signal access for staff and guests alike.
• Boston Children’s Hospital added a hybrid 5G network to support thousands of mobile devices across departments.
• A major e-commerce company installed an LTE/5G signal indoor network across its 430,000-square-foot warehouse to support safety tools and logistics equipment.

We work with offices, hospitals, and campuses facing these same coverage challenges. Our goal is to remove dead zones without forcing teams to replace their devices or phone plans.

Private coverage in secure or regulated facilities

Private cellular networks give tighter control over signal, data, and access. Many hospitals, labs, and industrial sites use them to meet strict reliability or compliance requirements.

Bethlem Royal Hospital installed a private 5G network to support digital health records and clinician tools.

Cleveland Clinic used 5G to support patient monitoring and AR-based staff training.

Frankfurt University Hospital brought mobile ultrasound and real-time records to bedside care using private 5G.

Some industrial zones go the same route. One quarry used a Nokia LTE setup to connect equipment and workers across a site with no Wi-Fi.

We often meet clients who want the benefits of private LTE—without the operational overhead. Meter’s managed system brings strong, indoor cellular coverage to spaces where public networks fall short.

Cellular network frameworks explained

Cellular networks rely on different layers working together—radios, transport, user profiles, and traffic rules. Each one plays a role in keeping connections stable and usable indoors.

Base stations, core networks, and SIMs

Base stations connect nearby phones and devices using radio signals. Each one sends traffic back to the network core over fiber or microwave. The core handles tasks like routing, device registration, and access control. It also connects mobile traffic to the broader internet or private resources.

SIM cards identify each device and tell the network what it’s allowed to do. Most phones still use physical SIMs, but eSIMs and virtual SIMs are becoming more common.

At Meter, we remove the need for SIMs by using the carrier signal already available. That simplifies access, reduces support issues, and helps IT teams skip time-consuming provisioning steps.

Network slicing and QoS

A single network can be split into isolated lanes called slices. One slice might support admin traffic, while another handles voice or security cameras. Each slice runs separately, even though they use the same hardware.

Quality of Service (QoS) settings prioritize certain traffic types. Calls, video, or machine controls can be placed ahead of background traffic to improve reliability.

Good performance depends on how well the network handles load and conflict. That’s why our design includes secure network design principles like isolation, traffic shaping, and fallback planning.

What enterprises need from the network

Strong signal solves part of the problem. Enterprise teams also need reliability, control, and visibility across their buildings.

Public networks offer reach but little customization. Private systems allow more control but come with operational overhead.

We aim to bridge that gap. 

Our cellular service delivers enterprise-grade mobile coverage indoors with simple tools, managed support, and no need to own radios or spectrum.

CBRS, LTE, and enterprise connectivity

CBRS gives U.S. businesses access to LTE without buying licensed spectrum. The system uses mid-band spectrum in the 3.5 GHz range and follows a shared access model managed by the Federal Communications Commission (FCC). A dynamic coordination service assigns spectrum based on location and activity, which helps avoid signal conflicts.

Private LTE setups using CBRS are useful where public networks fall short. Office buildings with blocked areas, ports with heavy radio use, and industrial zones with security requirements are common fits.

Managing a CBRS deployment takes more than installing hardware. Teams have to handle licensing, radio tuning, SIM logistics, and backend policy control. Most IT departments don’t have the time—or the budget—to build and support all of that.

Meter offers a managed option that skips the complexity.

Instead of radios or licensed spectrum, we use Cellular Access Points (CAPs) that extend existing LTE and 5G carrier signals indoors. There’s no SIM provisioning, no interference planning, and no on-site radio management.

Deployment is fully supported through network lifecycle management, which means fewer tickets, fewer surprises, and more stable service for users who rely on mobile access inside buildings.

How Meter enables reliable cellular performance

Meter gives buildings strong indoor LTE and 5G without SIM cards or radio licenses. We bring in the carrier signal already reaching the building and extend it inside using our own CAPs.

Other systems often need custom radios or full private setups. That can mean extra contracts, hardware, and time from your team.

We remove that work.

There’s no need to manage SIMs or deal with wireless carriers. Phones and tablets stay online inside offices, clinics, or remote work sites—even in spots where the signal usually drops. Users connect the same way they always do. No special settings or logins are required.

It works well in concrete buildings, large warehouses, or places with limited outdoor coverage. It’s also a fit for teams that use personal or company-owned phones on the same network.

Meter handles everything behind the scenes and ties into your current enterprise network infrastructure without added tools or hardware.
