Blog: GPS Pet Trackers networks: Why your dog’s safety depends on the right connection

When your pet goes missing wearing a GPS tracker, the difference between a successful reunion and heartbreak often comes down to cellular network technology. Your GPS tracker might know exactly where your pet is, but without reliable cellular connection, that critical information never reaches the app on your phone. The satellite knows, but you don’t.

At the home of pet safety, PetLink understands that the network powering your GPS tracker isn’t just technical specs—it’s the invisible lifeline that determines whether your device works when you need it most.

How GPS tracking actually works

GPS tracking involves two separate technologies working together seamlessly. First, your tracker’s GPS chip receives signals from satellites and calculates your pet’s exact location. Second, cellular networks transmit that location data to your smartphone app in real-time.

This two-step process reveals a crucial point: even if your GPS tracker device knows exactly where your pet is, without reliable cellular connection, that information is rendered useless during an emergency. The technology is only as strong as its weakest link.

Why older networks have failed pet parents

Many GPS trackers purchased just a few years ago have stopped working due to systematic network shutdowns. Major carriers have discontinued older technologies on a predictable timeline:

2G networks shut down completely between 2017-2020, leaving thousands of pet trackers permanently offline. 3G networks followed suit, with all major carriers completing shutdowns by 2022.

Pet parents discovered their “lifetime” trackers had become expensive paperweights overnight, often during emergencies when they needed them most. Unlike smartphones that people upgrade regularly, pet trackers are expected to last for years—making network obsolescence particularly devastating for families who depended on these devices for their pet’s safety.

Understanding modern network options

Today’s GPS trackers primarily use two network types, each designed for different needs:

• Standard 4G LTE Networks

Standard 4G LTE offers reliable data transmission and good urban coverage. These systems work well in cities and suburbs, providing regular location updates and supporting advanced tracker features. However, they typically consume more battery power and may have coverage limitations in remote rural areas or inside buildings where scared pets often hide.

• LTE-M Technology

LTE-M represents a new approach, specifically engineered for devices like pet trackers. This technology is designed for extended coverage in challenging environments, improved battery efficiency compared to standard 4G, and maintained connectivity during high network usage periods. LTE-M networks are built with Internet of Things (IoT) devices as a priority, making them well-suited for pet tracking applications.

Real-world performance differences

The difference in network technology becomes apparent in challenging situations where lost pets are most likely to seek shelter:

Areas where standard networks may struggle:

• Dense forests or mountainous terrain
• Indoor locations like garages, sheds, or basements
• Rural areas with limited cell tower coverage
• Underground spaces where frightened pets hide
• During emergencies when networks experience high traffic

LTE-M technology is specifically designed to address many of these coverage challenges, providing more reliable connectivity in the difficult environments where traditional networks often fail. Like all technologies, it’s not perfect in every situation but LTE-M is currently the best pet tracer option.

Why PetLink chose AT&T’s LTE-M network

• PetLink’s partnership with AT&T’s LTE-M network provides several key advantages for pet tracking:

• Extended Coverage: Reaches areas where standard networks may struggle, including better performance in rural areas and inside buildings where scared pets often hide.

• Battery Efficiency: LTE-M technology is designed to consume less power than standard 4G connections, extending device life between charges.

• Network Reliability: Maintains connections during high-usage periods when standard networks may experience congestion, with IoT device connectivity designed as a priority.

What to ask before buying any GPS tracker

Protect your investment by asking the right questions:

• Network Specifics: Ask exactly which cellular technology the device uses—not vague claims about “4G connectivity.” Verify whether it’s standard 4G LTE or LTE-M technology.

• Future-Proofing: Understand the expected lifespan of the network technology and whether the company offers upgrades if networks change.

• Coverage Reality: Request realistic coverage expectations for your specific area and lifestyle, not theoretical maximum coverage claims.

• Emergency Performance: Verify how the device performs during lost pet situations and whether it maintains connectivity during network congestion.

Red flags to avoid

Be wary of marketing claims that often indicate outdated or inferior technology:

• ‘Works on all networks’ usually means older, less reliable technology
• ‘Lifetime service’ promises are impossible to guarantee as network technology evolves
• Vague coverage claims without specific network partnerships

Instead, look for specific network partnerships, transparent coverage information, and clear policies that protect your long-term investment.

Making the right choice for your lifestyle

• Urban Pet Parents: Both LTE-M and standard 4G networks can work well, though LTE-M typically provides better indoor tracking when pets hide in buildings.

• Rural Families: LTE-M technology offers advantages for reliable coverage in remote areas where standard 4G networks may have limitations.

• Adventure Families: Those who hike, camp, or travel benefit from LTE-M’s design for challenging terrain and diverse conditions.

• All Pet Parents: Choosing future-proof technology prevents expensive replacements during network transitions.

The future of pet tracking networks

Network technology continues to evolve, with emerging technologies like 5G and satellite integration potentially enhancing pet tracking capabilities. However, LTE-M currently represents an optimal balance of performance, efficiency, and reliability for pet safety applications.

PetLink’s partnership with AT&T’s LTE-M network ensures your pet tracker continues working reliably, with support for seamless transitions as technology evolves.

The bottom line on pet tracker networks

Your GPS tracker’s network technology may be invisible, but its impact on your pet’s safety is profound. When choosing a GPS tracker, the network technology often matters more than device features alone.

Standard 4G and LTE-M networks each offer different advantages, but LTE-M technology is specifically designed for the unique challenges of pet tracking applications. When your pet’s safety depends on reliable communication, choosing a pet tracker with purpose-built network technology can make the difference between a successful rescue and a heartbreaking outcome.

Your pet’s safety shouldn’t depend on outdated or inappropriate network technology. Choose the connection designed to work when every second counts.
