Hi Anant, I added on the UE capabilities a filter by band, number of carriers, or uplink CA

Hi Jesse, I added in the "Export" menu a search for a single frequency, a frequency range, in uplink or downlink, for all technos. The menu name is not intuitive but I did not find where else to add it

Could you add a search function for LTE bands where you enter a frequency or a frequency range and it would show all bands that include that frequency/range? Would be really useful!

Hi, Is it possible to support INTEL chipset based UE CAPABILITY INFORMATION protocol message?

Sunil Joseph

I believe measurement gaps ought to be 6ms long everytime. When selecting gapoffsets can they be spread over two SFNs ?. If my understanding is correct, then the display does not show the entire 6 sub frames in such cases

Hello ,excellent work ! I wonder if the bands 5150-5250 and 5725-5850 are for LTE downlink or Uplink, because in the LTE field i found the specification of DL only and in the WIFI field is marked LTE UL !! Thank u in advance :)

You are right, I changed the column name

Stefan Blomeier

Dear Sir, regarding LTE TDD you made nice table and picture for the SSF. But I think there is a mistake in the description for "SSF Special SubFrame, normal CP (Dw / GP / Up)" => you named the column "number of slots per subframe" but it should be rather "number of OFDM-Symbols per subframe" as the Normal CP allows for 14 Symbols in a Subframe of 1ms. thanks for your great tables and analysis. I appreciate your efforts. kind regards, Stefan

Great site, use it a lot. On page http://niviuk.free.fr/lte_ca_spectrum.php bands above 3800MHz (ie. band 46, 252, 255) fall of the chart. Would also be great if these items are available as excel download files, so that I could make my own charts. Keep up the good work!

Could you add LTE Band 71 to the list?

21 04 2017

Dear Niviuk, I have used LTE sounding reference signal page in order to see allocation. I think there is a mistake in Ko overline calculation. Instead of using mSRS,0, mSRS,Bsrs is used. Regards, Daniel

The Fd_low for band 46 is incorrect. It should be 46790 as per 36.101

Actually just downloaded the file again and it looks like I downloaded it just before you fixed it. Looks good now.

Great site! BTW: I just noticed the downloadable version still has the wrong range for LTE Band 70.

01 09 2016
21:46

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
14:59

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.

30 08 2016

Walktester

Hi, I would like to know what are the frequency channels for Verizon and ATT in Philly

16 08 2016
09:42

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).

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
11:58

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"? Ralph.

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).

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

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.

17 01 2016

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.

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
22:50

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
17:07

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
07:51

Jacob

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?

27 11 2015

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 Martin

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.
