Determining RF Performance


Trip

Recommended Posts

Is there any way of determining what a phone's RF performance is short of buying it?  I always see specs on battery life and processor performance, but never RF performance.  I ask because I know my LG G6, for example, has far worse RF performance than the Moto E5 Plays even on the same network.  Given how much time I spend in rural areas, I really need to make sure my next phone is a better performer in weak signal conditions.

Some people can interpret the FCC certs and predict how a phone should perform, AJ used to do write ups on flagship phones years ago. From my experience LG seems to be subpar to Samsung, but they're about the only two manufacturers I've played around with recently.  I went from an LG v20 to a Galaxy S9+ when I came back to Sprint and the difference was night and day. My LG phone would constantly drop to 3G just riding in a car.

The FCC certifications are designed to deal with RF exposure/output and determine if the device is safe to use.  While a lower EIRP from the phone could indicate reduced RF performance, that's not necessarily the case.

I need to figure out if other phones have a feature like LG's "Knock On" and contemplate those as I look at new devices.

Every phone reviewer I've seen doesn't care to review RF performance. And every blue moon when someone attempts to review RF performance, they do it completely wrong. I have just about given up looking for info myself since there is no way to say which phone is good and which is not. Even FCC data doesn't tell us much (the Note 2 proved that).

All I do now is just keep an eye out on forums to see if there are known signal issues on new phones. I've been pretty satisfied with OnePlus. Better than the iPhone series IMO.

    • Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
    • Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.
    • Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
