GPS is great — until it isn't. Park a trailer inside a warehouse, drop a container at a port, or leave equipment in a dense urban canyon, and your tracker goes quiet. You're left staring at a stale last-known position wondering if your asset is still there or halfway across town.
Starting today, that gap gets a lot smaller. Hapn trackers can now estimate their location using nearby WiFi networks and cell towers when GPS isn't available — and the live map makes it crystal clear what you're looking at.
What Is Location Assist?
Location Assist is a fallback positioning system built into Hapn's newest hardware. When a tracker can't lock onto GPS satellites, it scans for nearby WiFi access points or connects to cell towers and uses that information to estimate where it is. The position isn't as precise as GPS, but it's dramatically better than no position at all.
The key difference from GPS: these positions are approximate. A WiFi-based position is typically accurate to within 50–200 feet. A cell tower position can cover a range of a quarter mile to a full mile, depending on tower density in the area. Hapn now shows you that difference right on the map so you always know how much to trust a position.
What You'll See on the Map
We designed Location Assist to be obvious when it's active, without getting in the way when everything is running on GPS as usual.
Accuracy Halos — When a tracker is reporting a WiFi or cell position, you'll see a colored halo around the pin on the map. This halo represents the area where the tracker could actually be. Amber halos indicate WiFi positions (smaller area, higher confidence). Pink halos indicate cell tower positions (larger area, wider range). GPS positions look exactly the same as they always have — no halo, no extra indicators.
Source Badges on Tracker Cards — In the asset sidebar, trackers using WiFi or cell positioning show a small badge next to their status ("WiFi Location" or "Cell Location"). If you don't see a badge, the tracker is on GPS — we only flag the exceptions, not the baseline.
Map Legend — A new collapsible legend in the top-right corner of the map explains what the amber and pink halos mean, including their typical accuracy ranges. Expand it when you need a refresher, collapse it when you don't.
First-Time Explainer — The first time you encounter a non-GPS position on the live map, a brief popup walks you through what you're seeing. Read it once, dismiss it, and you're set.
Why This Matters
If you manage a fleet or track high-value equipment, you've probably dealt with the frustration of a tracker going dark indoors. Before Location Assist, your options were limited — wait for the tracker to get a GPS fix, or check back later. Now, you get an estimated position immediately, and the map is honest about how precise that estimate is.
That honesty is the design philosophy behind the entire feature. We don't want you dispatching a driver to a cell tower half a mile from your actual asset. The halo shows you the real picture: your tracker is somewhere in this area. Plan accordingly.
For individual users tracking personal vehicles or belongings, it means fewer gaps in your timeline and more peace of mind. Even when GPS can't reach your tracker, you'll still see roughly where it is.
How It Works Behind the Scenes
When GPS signals are weak or unavailable, the tracker automatically falls back to alternative positioning:
- WiFi Positioning — The tracker scans for nearby WiFi networks and compares them against a global database of known access point locations. This works best in urban and suburban areas where WiFi networks are dense.
- Cell Tower Positioning — If WiFi isn't available either, the tracker uses its connection to nearby cell towers to estimate location. Accuracy depends on how many towers are in range and how close they are.
- Automatic Switching — You don't have to do anything. The tracker picks the best available method automatically and Hapn displays the result with the appropriate accuracy indicator.
Get Started Today
Location Assist is available now on the Hapn live map at app.gethapn.com, with mobile support coming soon. If your tracker supports WiFi and cell positioning, you'll start seeing it automatically the next time GPS isn't available — no settings to change, no firmware to update.
Log in to your Hapn account and check your assets. If you see an amber or pink halo, Location Assist is already working for you.
