Niviuk, thanks for fixing the frequency calculator for 5GTF. |
23 11 2017 |
Alfonso |
Thanks Niviuk! |

5G TF calculator issue is fixed. 5G TF UL/DL ratio is not 3GPP, it is only a predefined static choice to display alternate UL and DL subframes. I can try to propose a digital value for UL and DL to avoid predefined choices |

Alfonso |
Great work Niviuk! The web is very useful. One question: in http://niviuk.free.fr/fiveg_sfn.php in the 5G TF Frame parameters there's one UL/DL data cycle. Where in the specs can I find this parameter? |

Hi, I have sometimes some errors as well, the web pages are hosted on a mutualised server, then may be when there is some higher network traffic, or server issues ? an area where I have no control. Regards |

This is a very useful tool, thank you, Niviuk, for making it! Not sure if it only happens to me or my friend, seems recently the webpage(s)/tables doesn't show up correctly. We tried Chrome/Firefox or even MS IE, but same issue. Any ideas? |

Hi, for all techno, there is now an option to search for a frequency range. The filter/sort option is now saved after selection. LTE geographical area option is selected by default. I disabled the UMTS equivalent band by default, but I can enable it back easily. Cheers |

Thanks for such a useful resource. I use the LTE bands page once or twice a week! A few suggestions: 1) I find that every time I go to the LTE bands page, I change the sort order (it's not actually a 'Filter') to "DL Increasing" and turn on the Geography checkbox. Any chance those can be made the default?, 2) After changing and pressing Display, the Filter popup and checkboxes change back to their default; it would be nice if they stayed at the selected value to indicate what the table is showing (that confused me a couple of times), 3) It doesn't seem you can turn off the channel numbers anymore; the EARFCN check box appears to be ignored. I swear this used to work. |

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 |
20 08 2017 |
Jesse |
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! |

Dear, where Can I find information about LMS(Layer Management strategy) in LTE? |
23 07 2017 |

Sunil, fixed gapoffsets that can be spread over two SFNs |
23 07 2017 |
Niviuk |
Anant, added dl-256QAM and ul-64QAM-r12 information associated to each LTE band |

Anant |
Hi,
Is it possible to support INTEL chipset based UE CAPABILITY INFORMATION protocol message? |
18 07 2017 |
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 |

Bill, from Wikipedia LTE networks, B3 is used widely : Europe, Asia, Korea, Africa, Australia, South America, but not in USA |

Hello,
Enhancement Request to existing UE Capabilities Tool:
Is it possible to include dl-256QAM, ul-64QAM-r12 information associated to each LTE band?
Thanks, |

Iman |
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 :) |

Hi, I need to search on the web, as I don't know how that can be done, I guess calling the php functions from any client |

Vignesh Kannan |
Excellent data. I am wondering whether you guys provide any API's to access the information from a code. I did go through the export section. But I am curious about the API side. Thanks |
30 05 2017 |
Niviuk |
You are right, I changed the column name |
29 05 2017 |
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 |
Saken |
Hello! Could you please add information about Kazakhstan networks, if you want I can send it to you... And also it would be better to update information about Samsung devices (They support a lot more LTE bands than it shown here) |

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.

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 |
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. |
30 08 2016 |
Walktester |
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"?

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.

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 |

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 |
