One easy enough term in the cellular lexicon that may lead to lots of confusion is “band”. therefore in a shot to induce you up to hurry, here’s my take on what that basically suggests that.
Bands are groupings of frequencies of the radio-frequency spectrum. Specific bands are assigned to different carriers for their use. this is often nothing new. It’s something that’s been done with radio, t v and currently cellular.
Let’s verify t v as a simple example. within the days once they used to have ultrahigh frequency and VHF (or with radio, AM and FM), participants might choose their own channels at intervals those bands.
In the mobile world, there are multiple bands, a number of that don't seem to be certain jurisdictions. every band is assigned a reference range, that indicates a block of frequencies (e.g. 850 to 890 rate is Band 5). therefore why are bands therefore important? Let’s say you cosmopolitan to European country and purchased a phone. It’s possibly that the phone are going to be compatible with Band but, it would not work on networks within the U.S. since major carriers like T-Mobile and AT&T use Bands two, 4 and 5.
If you’re shopping for a phone direct from a carrier, your phone is meant to figure on their network. however if you purchase from Amazon or the phone manufacturer, you need to verify that it’s compatible with the band used by your carrier.
Here’s wherever Cel-Fi fits in. just like a phone, a wise signal booster needs to be designed to match the suitable bands for your carrier. but not like a phone, you can’t get a 14-year-old on the corner to unlock your Cel-Fi system – and that’s an honest factor. as a result of Cel-Fi is carrier specific (and independent agency compliant) it's licensed to figure at much higher levels for every carrier than the other booster out there.
