Great site! BTW: I just noticed the downloadable version still has the wrong range for LTE Band 70. |
01 09 2016 |
Niviuk |
RS, I changed the Earfcn values for B70 to fit with the frequency band range, waiting for the next 3GPP release.
Wazzup, the RRC message UE Capability Information provides all the CA combinations supported by the device |
31 08 2016 |
RS |
Great site, use it regularly for my work.
LTE Band 70 seems to be incorrect, UL should be 1695-1710MHz and DL 1995-220MHz. However EARFCNs in the spec also seem to be wrong. |

Hi, I would like to know what are the frequency channels for Verizon and ATT in Philly |
16 08 2016 |
Wazzup? |
Wonderful site! One question though, is there a way to know the CA bands (and bandwidths) that are supported by a LTE phone/chipset? It might be traced via capability messages but before enabling CA on some bands, we would like to be able to know if it will be used or not (even though it is specified in 3GPP CA band combinations). |

Hi, the best tool I ever seen for 3GPP bands!
Only 3GPPv14 approved bands 69 and 70 are not yet included, I assume they will be soon added :o) |

Very nice and useful database. I'm wondering why powerful 3GPP and other forum like IEEE do not have such nice tool, or maybe I did'nt found them. I'll keep the link and share it !
Thanks to all the contributors. I hope to be able to support such nice initiative. |

Hi, I found European DD bands range is 703-733, 758-788 MHz which fits in the same range as band 28, then it should be renamed from 700 APT to 700 AP + EU, for Asia Pacific + Europe |
05 06 2016 |
Ralph A. Schmid |
Hi!
Great site, I started years ago using it.
One thing, is the new European DD 700 MHz LTE band the same like "28 700 APT"?

It appears that your Band 66 downlink EARFCN middle and high values are incorrect on your chart. The form appears to calculate them correctly (65536 offset from uplink). |

Why not about TETRA, do you know how to calculate the radio channels, is it ETSI TS 100 392-15 ? |
06 03 2016 |
Niviuk |
Hi Dave, Wikipedia offers many detailed network operators information, but no sorting is possible. I have added all the structure to show operators and devices frequency information here Supported bands. There is some filtering by country, or operator or brand. Hope some smartphone vendors or network operators will fill it. Cheers |

Can anybody suggest how I may find which Bands (all protocols) are deployed by country? Easy to find which freq ranges are deployed by country, but I need that broken down by bands. Thanks |

The CDMA frequency/channel search is not populating the Band 0 line which is causing the rest of the display to not work proper. All of the other columns are a space off since the other values are accounting for the Band 0 spot.

Hi, probably higher interferences on the overlapping zone |
08 01 2016 |
Jacob Wu |
Hi there, I have a customer says their L1800 frequency allocation as follows:
DL LTE F1 (L1800): Earfcn 1300, Fc DL 1815.0 MHz, 20Mhz BW
DL LTE F2 (L1800): Earfcn 1471, Fc DL 1832.1 MHz, 15Mhz BW
That means for F1, the frequency range is from 1805~1825MHz. For F2, it is from 1824.6~1839.6.
My question is, is it possible to use this kind of configuration with 0.4 overlapped frequency? (F1 ends at 1825, F2 starts at 1824.6)
Thanks. |

Might be nice to add upcoming 5G bands from World Radiocommunication Conference on 12/3/2015 |

Hi Mike, the PRS upper frame grid is using a static value of PRS Index equal to 0, whereas the lower whole SFN view takes into account the PRS configuration Index input. This explains the difference. I am searching for a solution to fix that |
03 12 2015 |
Niviuk |
Hi Jacob, the 5 MHz bandwidth includes a guard band on both sides. We can use an effective bandwidth value of 4.68 MHz. For Band 1, the Freq offset is equal to 0, then Freq = Arfcn / 5. The lowest DL Arfcn is 10562, or a central frequency of 2112.4 MHz with 2.34MHz bandwidth on each side = [ 2110.06 .. 2114.74 ]. Same formula for the highest Arfcn 10838 |
03 12 2015 |
Mike Morgan |
Hi there. Great site. Just had a comment on the OTDOA. I was putting in some different settings and noticed that the grid view (PRB vs subFrames) showed PRS starting on subFrame 0 and then when I looked down the page at the view over whole SFN period of 1024 frames showed the PRS pattern starting in subFrame 1. just wanted to bring that to your attention. |
02 12 2015 |

Hi there, have a question here. For UMTS band1, the first channel center frequency is 2112.4MHz which means the operating bandwidth is from 2110~2115MHz (backward 2.4MHz, forward 2.6MHz); the last channel center frequency is 2167.6MHz, and the operating bandwidth is from 2165~2170 (backward 2.6MHz, forward 2.4MHz). With a known center frequency, How could I determine the operating bandwidth? Backward 2.4MHz or 2.6MHz? |

Sur la page Frequency search, on peut chercher pour une frequence toutes les bandes en LTE, UMTS, ... Et il y aussi une possibilité d'exporter les tables utilisées pour le calcul. Si cela ne correspond pas ce que vous aimeriez trouver, vous pouvez m'envoyer par mail une description plus detaillee. Je regarderais. Cdlt |

Est ce que vous avez une api ? Si non, est ce que vous pourriez offrir ce genre de service ?
L'idée est d'avoir un moyen rapide d'avoir les informations sur une bande de fréquence (GSM, UMTS...) a travers un programme.
Merci d'avance

Hello,
LTE band 31 is more EALA than CALA although Brasil has shown interest in this frequency band. It was originally used in the Nordics for NMT450 where it was later replaced by CDMA450 which is now migrated to LTE450.
NMT450 was also used in Poland, Russia, Ukraine, Saudi Arabia etc. |

UE Categories |
There is mis-typed information within the Downlink Categories table, for downlink category 16 under "Maximum number of bits of a DL-SCH transport block received within a TTI" you have
149776 (4 layers, 256QAM)
It should read,
149776 (4 layers, 64QAM)
195816 (4 layers, 256QAM) |

Hi Mr Wad, nice to hear from you. Your LTE web pages are useful, with a good graphical design. I did not know how to contact you before doing a copy, and as you may have seen, I added on the web pages it was a copy from your previous web site. I can add your name as the author if you wish, and of course, I will remove the copy if you ask me to do so. Cheers. LG |

Hi. I noticed that this site has a copy of my original LTE resource grid and other tools. That's fine, because I had some bad luck with my old web hosts, and haven't yet found a solution that works for me. I do want to let you know that my web pages are still available at an awfully long Google Drive URL, which can be accessed via:
http://tinyurl.com/pewscorner (then select "LTE stuff" from the menu).
The full URL is:

The band numbers in the GSM table are wrong.
Number given in the table refer to the chapter number in 45.005.
Please align with UMTS and LTS bands or remove bands for GSM, to avoid confusions. |

Dears,
Maybe to be more precise about request on resource grid, it will be more than useful to take into consideration the new transmission mode TM9/10 which induces additional overhead on FDD LTE resource grid (TDD maybe ?).
Indeed, thanks to this new TM, it is possible to perform SU-MIMO 4xn & SU-MIMO 8xn using new reference signals (CSI-RS & DMRS). Hopefully, you will have enough time to add this request into the pipe :)
Cheers, the site is great !

Hi Mr student, it allows to break the link between UL and DL for the future categories. A device will declare a legacy category common for UL and DL, and may add a specific DL or UL cat. The additional UL/DL cat allows to define new 3GPP Release 12 categories, for instance category 0 for low complexity devices; it may be useful also to indicate new capabilities to the network like the support of UL 64QAM, or just indicate enhanced throughput either in DL or UL.The device should be compliant with the combinations set rules at the bottom of the page. Cheers |

I changed to "AWS-1 +" so that AWS-3 can be used for the new band to come in the 3GPP. Please tell me if there is any other usual naming for B10 |
18 03 2015 |

LTE Band 10 is mistakenly listed as AWS 1+3, but does not cover the entire gamut up to xx80 MHz. A new superset LTE band is required. |

Hi Gautam, the umts page is built from several include files. The freq/arfcn info is using a php array that you can export to Excel from this link http://niviuk.free.fr/wls_search.php. The formula to compute arfcn or frequency is displayed in an example at the bottom of the umts_band page. I think that with the export table and the formula, you have all the data to be able to generate the umts tables in any language |

Hi Disinto, I have tried to add some filtering on the CA spectrum page lte_ca_spectrum.php. I don't find the result convincing, but I added it anyway. You can drop me a mail if it is not what you had in mind. Cheers, LG |

I usually cross check the standardized/future CA pairs here: http://www.3gpp.org/DynaReport/SpecVsWi--36101.htm |
09 02 2015 |
Disinto |
I'm in the telecom business and use your site nearly on a daily basis, especially for CA pairs. Two comments though:
- Can you specify which revision of TS36.101 you consider in your tables? (e.g. 3GPP 36.101 Rel12 June'14
- Would it be possible to have a spectrum graphical view segregated by low band, medium band and high bands? It'd help spotting overlaps more easily (i.e. B38/B41 and B28/B20)
Merci :) |

Have you thought about making a mobile app for your website?

One remark : China is no longer on B38 as MIIT finally decided that B41 would be the main profile for the 2.5 GHz band (just like Japan and US). So B38 is no longer for "China" as mentioned, and I would say that B38 is "EMEA" just like B7 (since they were designed together in the CEPT band plan) |
