Calling all devs, 5GHz Wifi - Asus Eee Pad Transformer Prime

Is doable...
in our device /system/etc/nvram_nh615.txt
that file has the configuration for our wifi
if you notice, you will see 2g in there, anything that says 2g should have a 5g version in it.. but doesnt...
ive come up with this edited file:

the only thing is i dont think its a copy past kind of thing, there may be extra options and what not, but its evident that 5ghz support is easy to add (galaxy s 2 has roms that have 5ghz support and some that dont)

The radio hardware must be capable of 5Ghz frequency. It's not just software.

I was not aware that the Azurewave WiFi controller in the Prime had 5GHz radios in it? Without a 5GHz radio, it won't matter much was you do on the software side, you won't have 5GHz support.

Even if its possible, I dont think it would add anything to table, people complain 2.4Ghz range, 5 Ghz makes it worse

Hrm, I was also under the impression we had a broadcom dual band chip in these. Can someone confirm?

I think we do. only way to confirm is go back to that teardown pic from GPS thread showing the broadcom chip. then run the serial number from it through Google or whatever to find out more details on it. No one is exactly sure if this does have the 5Ghz hardware or not.
Good idea Op. If this does have the hardware to push it, might be one of the many ways to improve wifi for those who think it could be better on range or stability of signal.

Found this info about the chip we have.
Product reference: BCM4330
Title: 802.11a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0+HS and FM Transceiver
Description: The Broadcom BCM4330 single chip device provides the highest level of integration for a mobile or handheld wireless system, with integrated IEEE 802.11 a/b/g and single-stream 802.11 n (MAC/baseband/radio), Bluetooth 4.0+HS, and FM radio receiver and transmitter. It includes on-chip 2.4GHz and 5 GHz WLAN power amplifies that meet the output power requirements for most handheld systems while permitting and optional external power amplifier for higher output power applications, if requires.
Utilizing advanced design techniques and process technology to reduce active and idle power, the BCM4330 is designed to address the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power topology and allows for operation direct from a mobile platform battery while maximizing battery life.
The BCM4330 implements the highly sophisticated Enhanced Collaborative Coexistence radio coexistence algorithms and hardware mechanisms, allowing for an extremely collaborative Bluetooth coexistence scheme along with coexistence support for external radios (such as GPS, WiMax, or Ultra Wide-band radio technologies, as well as cellular radios) and single shared antenna (2.4 GHz antenna for Bluetooth and WLAN). As a result, enhanced overall quality for simultaneous voice, video, and data transmission on a handheld system is achieved.

Where do you see the BCM4430? The Prime has the AzureWave AW-NH615. The AzureWave site has a ~610 part which is dual-band and a ~611 which is single-band. The 615 can be either.
It doesn't matter anyway. As already said, there's no antenna nor supporting circuitry for 5GHz. And even if there were, and you get it working, it'd be worse than 2.4GHz.

Thats some good news, hope we can get the FM Transmitter working too!

It's in the /vendor/firmware folder, maybe just unused?

It looks like the AW-NH615 is using the BCM header for compatibility reasons.
# bcm94329sdagb board
# $Copyright (C) 2008 Broadcom Corporation$
# $id$
# Azurewave Release 2011/03/21
# NH615
But per OP, if config has no "~5g" params, only "~2g", then it's a single-band (2.4GHz) part.

AW-NH615 looks to contain the BCM4330 ..... the firmware and kernel drives all point to it being a BCM chip .... probably the BCM4330

keep the research going. anything possible worth a try.

To what end? I have a NetGear N900 which is a beast. I use 5Ghz to avoid fighting with others for channels on 2.4GHz. I lose about 25% of the range by using 5GHz vs. 2.4GHz. If the Prime's Wi-Fi is weak(er), it'll be worse on 5GHz, not better. That's what e.mote was trying to say in his previous post. The only potential advantage to 5GHz on the Prime is to move Wi-Fi off the 2.4GHz band so it doesn't interfere with BT which is a problem that should be resolved by Asus without users having to hack their way to a solution.
Wi-Fi networks have limited range. A typical wireless access point using 802.11b or 802.11g with a stock antenna might have a range of 32 m (120 ft) indoors and 95 m (300 ft) outdoors. IEEE 802.11n, however, can exceed that range by more than two times.[38] Range also varies with frequency band. Wi-Fi in the 2.4 GHz frequency block has slightly better range than Wi-Fi in the 5 GHz frequency block which is used by 802.11a. On wireless routers with detachable antennas, it is possible to improve range by fitting upgraded antennas which have higher gain. Outdoor ranges can be improved to many kilometers through the use of high gain directional antennas at the router and remote device(s). In general, the maximum amount of power that a Wi-Fi device can transmit is limited by local regulations, such as FCC Part 15 in the US.

interestingly, the drivers mention the BCM4329 instead of the 4330.
This would explain the device's bluetooth 2.1 only functionality.
BCM 4329:
Broadcom's most integrated 65 nm single-chip combo device with single-band (2.4 GHz) 802.11b/g/n or dual-band (2.4 GHz and 5 GHz) 802.11a/b/g/n, plus Bluetooth 2.1 + EDR and FM receiver and transmitter features
Offers one of the industry's most advanced Bluetooth/Wi-Fi coexistence technologies to ensure the best possible user experience
Full featured, on-chip Power Management Unit supporting direct battery (2.3V to 5.5V) connection
Bluetooth Core Specification Version 2.1 + EDR compliant with provisions supporting future specifications and Bluetooth Class 1 or Class 2 transmitter operation
Supports 802.11n performance and range features, such as Space Time Block Coding (STBC), Short Gual Interval (SGI), A-MPDU aggregation, Block Ack, Greenfield, RIFS
