GPS-enabled medical alert systems extend emergency protection beyond the home to wherever the senior goes. But they cost more, require regular charging, and are not right for everyone. This guide helps you decide whether a GPS medical alert system is the right choice for your situation.
Who Needs GPS Coverage?
The core question is simple: does the senior regularly leave the home alone? If the answer is yes — driving, walking, grocery shopping, visiting friends — GPS protection makes sense. A home-only system provides no protection during those outings, which are often when seniors with mobility or cognitive issues are most at risk.
GPS is particularly important for seniors with early-stage dementia or mild cognitive impairment who may become disoriented or lost while out. For these users, the location tracking feature (which allows family members to see where their loved one is via a smartphone app) may be as valuable as the emergency response capability.
For seniors who rarely leave home alone — or who are always accompanied when they do — a home-only system is often sufficient and more affordable.
How GPS Medical Alert Systems Work
A GPS medical alert device is a cellular device that the user wears or carries. It connects to the cellular network (like a smartphone) rather than to a home base station. When the help button is pressed, the device calls the monitoring center through its own cellular connection, and the monitoring center can see the user’s GPS location — allowing them to dispatch the appropriate help to the right location.
Many systems also offer a companion smartphone app for family members and caregivers, showing the user’s location in real time and sending alerts if the help button is pressed or if fall detection activates.
Key Considerations for GPS Systems
Battery life: This is the most important practical consideration for GPS systems. Unlike home systems (where the base station is plugged in and the button battery lasts months), GPS devices run on rechargeable batteries that typically need charging every 24-72 hours. A device that is not charged provides no protection. Consider who will be responsible for ensuring the device is charged regularly.
Cellular coverage: The device uses cellular networks. Confirm the device works on a carrier with good coverage in your area. Most quality systems use major carrier networks (AT&T, T-Mobile, or Verizon).
GPS accuracy: GPS accuracy varies, particularly in dense urban areas or indoors. Most devices are accurate to within 10-30 feet outdoors. Indoor location is typically less precise, using cell tower triangulation.
Size and wearability: If the device is too large or uncomfortable, it will not be worn consistently. This is a critical practical issue — the most technically capable device is worthless if it sits on the nightstand.
Two-way communication: Can the monitoring center speak with the user through the device? Most GPS systems include a speaker and microphone so the user can communicate with the operator even without a phone.
GPS vs. Home System: Cost Comparison
Home systems typically cost $20-$35/month. GPS systems typically cost $35-$55/month, reflecting the higher cellular data costs and GPS infrastructure. Over a year, that difference adds up to $180-$240. For active seniors, the extra coverage is worth it. For primarily homebound seniors, the home system saves money without reducing protection for their actual lifestyle.
The Hybrid Approach
Several companies offer systems that combine both: a home base station for in-home use and a GPS device for outings. This maximizes coverage but comes at a higher cost ($45-$65/month for combined coverage). For some families, the complete peace of mind is worth the premium.
