EDX SignalPro alternative for land mobile coverage studies
Stolz Telecom · October 4, 2026
EDX SignalPro is the planning suite many consulting engineers run, and the name a dealer hears when a bid calls for a coverage study. This guide sets it beside Sentinel RF fact for fact, because the two were built for different jobs, and an operation should know which job is its own before paying for either.
What SignalPro is, and who it is for
SignalPro is the RF planning product of EDX Wireless. EDX describes it as an advanced RF prediction engine for today's wireless landscape, with propagation support from 30 MHz through 100 GHz, terrain, clutter and building data under the predictions, measured-data import for tuning its propagation models, and a GIS platform carrying all of it. The technologies it lists run from LTE and 5G NR through Wi-Fi 6 and 7, mesh and point-to-multipoint, LoRa and LPWAN, CBRS and fixed wireless, with add-on modules for 5G, mesh, LTE, in-building DAS planning and LoRa/IoT. Land mobile is one of its solution areas: EDX names P25, TETRA and DMR networks, area studies of base and portable coverage reliability, point-to-point backhaul paths with link margins, and export of coverage results as shapefiles for GIS platforms.
Its licensing, as EDX presents it, comes in project (short-term), subscription (ongoing) and hybrid (perpetual licenses plus scalable users) forms, with map data offered as a separate subscription. EDX publishes no price on its site, so none is quoted here. SignalPro is a trademark of EDX Wireless, Inc., and this guide describes it from EDX's published pages as of this writing.
Where it fits a two-way radio operation
If your operation designs cellular, Wi-Fi, mesh or IoT networks alongside land mobile, or employs engineers who tune propagation models against drive-test data, SignalPro is in its element: one platform spanning the technologies, a module for each, and the GIS to carry the data. System houses with staff RF engineers run it for that reason, and the consulting engineer who stamps the coverage exhibit on a public-safety bid often works in it.
Most dealers and integrators are not that operation. Their coverage questions are the land mobile ones: how far does this repeater reach and how good is it out there, will every siren hear it, will it pass TSB-88 acceptance, will the backhaul stay up, does the proposed station clear the incumbents. Those questions arrive beside the licensing and tower work, and the answer has to be something a customer can be handed. That is the job Sentinel RF was built to, and the table below is where the two differ.
Side by side
The SignalPro column states what EDX publishes, as of this writing. A row that says EDX's pages do not describe something means exactly that, and no more.
| EDX SignalPro | Sentinel RF | |
|---|---|---|
| Cost model | Project, subscription and hybrid (perpetual plus scalable users) licensing, with map data as a separate subscription. No price is published. | Subscription per operation with seats included: from $99 a month for the full product, or $29 for FCC search and monitoring alone. Every plan starts with a 14-day trial and no credit card. |
| Terrain data | Terrain, clutter and building data. EDX's map data subscription offers US terrain at 10 meters and hybrid clutter at 5 meters, with automatic updates. | USGS 3DEP at 1/3 arc-second, about 10 meters, and ESA WorldCover land cover, loaded and cached by the service and included in the plan. |
| Propagation model | A library of published propagation models from 30 MHz through 100 GHz, with measured-data import for tuning them. | Longley-Rice with terrain roughness measured at the site; Hata, COST-231 and Egli for quick estimates; the FCC's own curves where a Part 90 or Part 22 rule calls for them; Vigants-Barnett and ITU-R P.530 for microwave; P.2108 and P.833 clutter above 1 GHz. No custom model development. |
| FCC license and tower data | EDX's pages do not describe a built-in FCC license or antenna structure database. | A full weekly copy of ULS and the antenna structure register, leases and market licenses included. A callsign loads the site as filed, and incumbents for short-spacing, intermod and Part 101 screens come from the same copy. |
| TSB-88 tile study | EDX publishes material on TSB-88 Monte Carlo studies and simulcast planning in SignalPro. | A uniform tile grid with a Longley-Rice median per tile and area reliability against the channel performance criterion you enter, bounded to the area you trace or upload, with receive gain cited to the TSB-88 Annex D table. |
| Report output | Coverage results export as shapefiles for GIS platforms; LTE and 5G studies produce cell, neighbor-list and sector performance reports. | A letterheaded PDF for every study: parameters, results, the map, the method and the planning-study notices, kept in a report history. |
| License monitoring | Not part of the product as EDX describes it. | Renewal alerts at 180, 90 and 30 days, buildout deadlines, tower owner, status and height changes, FAA lighting NOTAMs, and area watches for new towers and licenses. |
| Who runs it | RF engineers and planning teams, licensed per user, project or seat. | Every seat in a dealer or integrator operation, in a browser, with saved studies and antenna patterns shared across the operation. |
What SignalPro does that Sentinel RF does not
- It plans LTE, 5G NR, Wi-Fi, mesh, LoRa and IoT, fixed wireless and in-building DAS. Sentinel RF's only cellular-technology study is the CBRS site study, and it has no in-building modeling.
- It carries a library of propagation models and lets an engineer tune them against measured data. Sentinel RF runs a fixed set of published models and offers no model development or tuning.
- EDX's own material covers simulcast planning with TSB-88 Monte Carlo studies. Sentinel RF's TSB-88 study predicts tile reliability for a site against the criterion you enter and does not model simulcast.
- It uses building data and runs Monte Carlo capacity simulations and automatic site-selection tools for network design. Sentinel RF models clutter from land cover, not individual buildings, and sizes nothing for you.
- It is a GIS platform that exports coverage as shapefiles. Sentinel RF imports a service-area boundary as GeoJSON or a shapefile, but its output is the report, not a GIS layer.
What Sentinel RF adds
The FCC copy sits under every study. A callsign loads the site as licensed, a short-spacing study names every incumbent that passes, fails or needs a letter of concurrence, a Part 101 screen names the controlling exposure on a microwave channel, and a site intermod study builds its frequency list from the tower you click, FM and TV included. Those are the studies a frequency coordinator or a bid reviewer asks for, and they come from the same weekly data the FCC publishes.
The studies are shaped to land mobile questions. A receive-site survey solves every siren or outstation on its own terrain profile and sorts them weakest first. A microwave path study resolves the rain zone from the coordinates and works availability to the annual percentage. A CBRS site study derives Category A or B under Part 96 and estimates the protection area. Thresholds, criteria and building losses are yours to enter, and nothing is chosen on your behalf.
The result is something you can hand over the same day. Every study prints under your operation's letterhead with the inputs and the method written out, and a saved study stores the inputs so that reopening it recomputes against today's FCC data and terrain.
And it is one subscription for the rest of the work: the license and tower watch lists, the FAA lighting-outage alerts, the FCC search on a map, and the cited answers from your own manuals, for every person in the operation rather than for one planning seat.
These are planning studies, not a measurement, and Sentinel RF is not an engineer of record. Where a bid requires a stamped coverage exhibit, the licensed engineer who stamps it chooses the tool, and the output here is there to inform that review rather than to stand in for it.
