[EVO 4G General] bitbang3r:
Search Market for "Sensorly" and install it. It shows 4G signal levels detected by users, and uses crowdsourcing to update itself. Broward by far has the best overall coverage so far, with Pembroke Pines probably having the best coverage of any single city within it.

By the way, I'm 99% sure that one of the towers is located north of Pines Blvd along the western edge of CB Smith Park. I got 4 bars while sitting a block away from the tower last night (mapping with Sensorly) ;-)

Now that I've managed to wardrive the middle third of Pembroke Pines for a couple of days and help fill in Sensorly's map, the tower range is looking a little more visible.

Despite Sensorly showing coverage, I can say for a fact that there's NO reliable 4G coverage at the intersection of Hiatus and Johnson Street, nor most of the extreme northeast corner of the mall's property. 4G kicks in along Johnson Street about halfway between Flamingo and Hiatus. At Flamingo and Johnson Street, it's rock-solid. So, it looks like the tower that's at the western edge of CB Smith Park (just north of Pines Blvd near 129th ave) has a range of about 1.5 miles from tower to fringe.

Tower #1: western edge of CB Smith Park, just north of Pines Blvd near 129th avenue. ~1.5 mile radius puts intersection of Hiatus and Johnson *just* a tiny bit outside its service area, and this is consistent with what I've observed. Sensorly's readings for that intersection are just wrong (probably due to GPS error and cars moving quickly from an area with service when Sensorly takes a reading, then rounds it due to gps error to the intersection), but the area to the east, west, and south has 4G. No detectable 4G along Hiatus between Johnson Street and Taft.

Tower #2: near Davie Road and Sheridan Street. Once again, a predicted radius of ~1.5 miles and accounting for GPS bias towards intersections gives a fairly consistent pattern of observed signal. Contrary to Sensorly's map, there's no meaningful signal at either Lowe's nor the plaza with both a Publix and Sprint store (west of University, between Pines and Johnson). Harbor Freight (University and Taft) had 2 4G bars and usable signal indoors. I'm not 100% sure about the intersection at Pines & University itself, but from what I remember, that intersection's coverage was either nonexistent or flaky, too.

Tower #3: Pembroke Pines municipal center, by the asterisk formed by Pines Blvd, Palm Ave, and the FPL power lines. HOWEVER, I think this tower is running at much lower power than the other two, because its footprint doesn't appear to be nearly as big as the first two. Pembroke Road is almost devoid of 4G. I can confirm that Taft Street is basically dead between Hiatus and Palm, as well. So, that would put the radius of tower #3 at roughly 1/2-3/4 mile.

Two more towers somewhere south/east of Pembroke Road and University. This area's kind of an enigma, because service existed in patches, but was not consistent. It's WAY too far from the Davie, Pembroke Muni, and CB Smith towers to be a signal from them, though.

I personally take full credit for just about every secondary road within a mile of Pines Blvd between I-75 and the Turnpike... it's oddly satisfying to go driving through an area, then see your path show up in green the next day. If somebody lives or works in a gated neighborhood that's large and has more or less free access to the whole area once beyond the gate, they should enable Sensorly, walk a '6', disable sensorly, wait a couple of minutes, walk a few hundred feet, re-enable sensorly, then walk a '9'. It would be kind of amusing to see a big '69' mapped into the middle of somewhere like Century Village ;-)

Update: OK, just spent an hour mapping the boundaries of the western half of the Pembroke Pines 4g service area. Once Sensorly updates in a few hours, you can pretty much believe that anywhere there's blue and no green between Pembroke Road and Sheridan Street east of I-75 and west of Hiatus either has no 4G, or is a community with a gate (confession: I did gate-crash a few neighborhoods where they were open for some reason, including the one between Pines Blvd and Pembroke Road east of 146th avenue.)
