OK, I have changed the name of the bands

Just FYI, the original iDEN 800 MHz SMR band is 806-825 MHz for TX, with RX 45 MHz above. So, if anything, it would be more appropriate to label LTE Band 27 as iDEN rather than Band 26...or delete all references to iDEN.

Answer to Stefan. The solution I found was to add a button to hide/unhide TDD and MBMS information in the ASN1 grammar. Cheers

Answer to Neel. Bug fixed : In UMTS, channel search is now allowed in both uplink and downlink

hello, just realized that MBMS is also a feature that up to know almost no Operator wants - except maybe in Japan or China. MBMS failed to get widely accepted. So it is rather nice to keep it separate in the ASN.1 code of WCDMA. As I already suggested to keep the entire TDD-ASN.1 separated from the WCDMA-FDD I would like to encourage also to keep the MBMS ASN.1 related messages and IE's separated. Moreover, TD-SCDMA is the only TDD version having survived, so I rather suggest to have a "chinese" LCR-TDD ASN.1 code. Note that also in Low-Chip-Rate TDD some channels like PDSCH and PUSCH are never used, similar in FDD. Maybe a clean-up of unnecessary ASN.1 IE's is advantageous to provide only the messages and IE's that are really used. That make searches in the WCDMA ASN. 1 simplier. However, there is a thin line between the fully beaty of exhausting information and keeping all stuff in WCDMA-ASN.1 and the practical usefulness. It is my personal opinion of course. Stefan.

your band3 is in correct please check channel=1288

Interesting idea. I have written a script that generates the html code from the 3GPP grammar, and it would require to filter the TDD IEs. No obvious filtering algo yet, I will look at it.

hello, it would be nice to split up the ASN.1 of UMTS RRC in two sections: A) UMTS FDD B) UMTS LCR (TD-SCDMA). No country uses both versions of UMTS, except maybe China. So it is rather simplier just see UMTS FDD messages and IE's without that TDD stuff. You Web-page is cool - useful. cheers, mate.

Effectivement, mais on trouve des infos sur plusieurs sites web dont les sites FCC US

Bonjour, où avez-vous trouvé les noms des bandes ? Dans les specs 3GPP, il n'y a que les n°. Sinon vraiment merci car c'est plus compréhensible pour référencer une bande que les n°.

Je ne sais pas si vous êtes au courant, mais votre site est devenu le site de facto pour les ingenieurs dans le "Test and Measurement" pour les calculs de canaux pour LTE. Chapeau et bonne continuation!

Hi, 36.101 for LTE and 25.101 for WCDMA. Added US WCS band plan

Hey! Cool info, i was wondering where can I double check info for the channel number in the lower 700 MHz band, do you have a 3GPP ref ?

I will check, UMTS bandwidth is 5MHz, so probably linked to the carrier frequency close to the 2.5MHz band edge

Unless you are using specific country frequency allocation, you made a mistake in the UMTS frequency range Band V. It should start from 824MHz

LTE Band 7 appears twice in the selection. Is that a mistake?

when we pick lte freq band it shows us the low and high channel, would it possile to also show the middle channel

Do you have updates on Japan LTE allocation around 895-905MHz??

In LTE calculator there is a mistake in Band 5 and 1.4 Mhz BW for the calculation. You can put in 869.8 and it automatically switches to another frequency = 869.7 Mhz with the corresponding earfcn.

Hi, I think there is a mistake in band 10, the downlink frequency is noted the same as for Band 4. Could you check that please? According to my information it should be 1805-1875,5 MHz. Thanks.

for the UMTS freq, UARFCN should be the correct name. by the way, great work!

Oups, sorry, for LTE band 37, it is rather UL high frequency that should be 1929.9Mhz instead of 1979.9Mhz

Lavaudoire

There must be be a mistake in LTE frequency band 37, DL high frequency is probably 1979.9 MHz and not 1929.9 MHz

The LTE EARFCNUL has changed in rel 8.4.0 (anyway for band I). Otherwise your web page is very useful.
