Andrea Tarasconi a écrit : | Dear Sir/Madam, | | even if we have an official TLA with Atheros, we cannot have the | needed support about few RF Register usage, so we are looking for | somebody giving us the needed support. | | What support we are looking for the Atheros AR5414 | ======================================= | The support we need to sombody very well knowing the Atheros chip-set | are both related to the RF Registers (not documented): | | - Operating in the 802.11a mode, how to move the base systhetized | frequency to 4600 or 4700 MHz and how to move to 5500 or 5600 MHz | instead of the 4800 MHz default. | | - How to change the RF channel stepping from the standard 2.5 and 5 MHz | stepping to a more fine 1 and 2 MHz stepping. | | Unfortunately there is no official documentation about and we were not | able to guess the correct numbers to write into the RF registers because | the structure of the RF Registers is very complex and quite completely | not documented! | | Any help will be appreciated. | | *A reward of 5000 USD will be provided to who will be able to give us | the two solutions (just the consultancy), otherwise a reward of 2000 USD | will be provide to who will give us only one solution.* | | Please feel free to forward this email to anybody you think may be able | to help us directly or indirectly forwarding to others. | | Thank you again for your cooperation. | Kind regards, | Andrea | | | Should you have any question, please do not hesitate to contact us. | Best regards, | | Dr. Andrea Tarasconi, Technical Director (CTO). | | Direct phone: +39 0522 9483.22 | Mobile: +39 335 8049677 | E-mail: andrea.tarasconi <at> essentia.it | <mailto:andrea.tarasconi <at> essentia.it> | | Essentia S.p.A. ?

What you are searching looks quite interesting even if I won't be able to give you the answer. I just have few questions: * I quickly read the atk5k source code and apparently, only the 4920 - 6100 Mhz is supported by the PHY. Does your chipset already work at 4800Mhz and you want to move to the 4600 - 4700 MHz band? * RF stepping of 1 MHz would mean that you will be able to set the frequency to 4601, 4602, 4603 MHz, right? Or do you mean the channel bandwidth (typical : 20Mhz, can be change to 5 or 10 MHz AFAIK) ? Adding the ath5k people since they might have better knowledge of this topic.
