Standard announced: Streaming without network!!

Posted by: Fred Mulder on 17 October 2009

Wires, routers, switches, complicated settings are history!

A Dutch audio site mentioned that Wifi Alliance (Intel, Cisco, Apple) have announced the new wifi standard. In two words: it enables a wireless connection between 2 devices without using a network. This will give streaming audio a big boots! Only a wireless streamer and NAS are required Smile To be released in 2010.

Greetings, Fred



´Wi-Fi Alliance® announces groundbreaking specification to support direct Wi-Fi connections between devices. Upcoming Wi-Fi CERTIFIED™ Wi-Fi Direct program will make it easy to connect devices directly to one another in a new kind of Wi-Fi network´

More info, see: www.wi-fi.org


Press release:
Austin, Texas, October 14, 2009 - Wi-Fi devices will soon be able to connect in a new way that makes it more simple and convenient than ever to do things like print, share and display. The Wi-Fi Alliance is nearing completion of a new specification to enable Wi-Fi devices to connect to one another without joining a traditional home, office, or hotspot network. The Wi-Fi Alliance expects to begin certification for this new specification in mid-2010, and products which achieve the certification will be designated Wi-Fi CERTIFIED Wi-Fi Direct.

The specification, previously code-named "Wi-Fi peer-to-peer," can be implemented in any Wi-Fi device, from mobile phones, cameras, printers, and notebook computers, to human interface devices such as keyboards and headphones. Significantly, devices that have been certified to the new specification will also be able to create connections with hundreds of millions of Wi-Fi CERTIFIED legacy devices already in use. Devices will be able to make a one-to-one connection, or a group of several devices can connect simultaneously.

"Wi-Fi Direct represents a leap forward for our industry. Wi-Fi users worldwide will benefit from a single-technology solution to transfer content and share applications quickly and easily among devices, even when a Wi-Fi access point isn't available," said Wi-Fi Alliance executive director Edgar Figueroa. "The impact is that Wi-Fi will become even more pervasive and useful for consumers and across the enterprise."

The specification targets both consumer electronics and enterprise applications, provides management features for enterprise environments, and includes WPA2® security. Devices that support the specification will be able to discover one another and advertise available services. Wi-Fi CERTIFIED Wi-Fi Direct devices will support typical Wi-Fi ranges and the same data rates as can be achieved with an infrastructure connection, so devices can connect from across a home or office and conduct bandwidth-hungry tasks with ease.

"With Wi-Fi technology already shipping in millions of consumer electronics devices and handsets every year, this is a terrific innovation for the industry," said Victoria Fodale, senior analyst and market intelligence manager at In-Stat. "Empowering devices to move content and share applications without having to join a network brings even more convenience and utility to Wi-Fi-enabled devices."

The Wi-Fi Alliance plans to publish its peer-to-peer specification upon completion, and will begin certifying devices for the Wi-Fi Direct designation in 2010. Only Wi-Fi Alliance member companies will be able to certify devices to the new specification.

Wires will still be more reliable (probably)

Perhaps, but it now seems that many network dummies/doubters have an easy route to streaming audio. Some purists will always stick with wires (lets not make this another wire vs wireless discussion).

It's very natural and definitely a winning strategy.
There are dozens of peer-to-peer opportunities around us.
Direct streaming of audio, video, photo, remote control Smile, mouse, keyboard, phone connections, PC connections etc...
IR and Bluetooth will die (I hope) if the new standard will be economical and energy-saving.

It's a very good message.

This isn't ground breaking tech but it will be great to have a standard to follow so that universal recognition becomes the norm. There are closed systems like SONOS that already have this type of function and beyond. Any will talk to any other and work as repeater besides.

When we see practical wireless mains I will be impressed.

interesting stuff, can anyone explain if this eliminates the need of a streamer, as we know it today?

When a remote control with user interface (similar to SB touch) controls the NAS directly using this wifi standard, then it would make sence if the NAS feeds the DAC with the necessary ones and zero's without a streamer in between?? (or am I missing something here Confused)

Well a stream is a streamer is a streamer. IF the network is just between an player and a nas the stuff will still need to be streamed.

I'll be honest assuming you have a robust network I fail to see how this is very exciting at all. I can see it being used by teeny boppers to play games on trains.

You'll still need a streamer in the same way as today.

There may be a performance increase if using wireless from UPnP server to UPnP renderer (for example) as currently this requires 2 wireless links (Server to Access point then AP to rendered) but fundermentally the wireless technology will be the same so if you have problems due to dropout because of distance from AP to renderer there is nothing (as far as I'm aware) in this mew specification to improve this - hense my initial comment of wired may still be an improvement.

I probably haven´t got a clear picture what a streamer actualy does. I though the streamer functions could be divided over the other devices.
I’ll try to clarify my thoughs, which will hopefully make it easy to spot my thinking flaw Smile

To start, I assume this is my current situation.
1. [Remote] Controls SB3 device: browse, select, forward, previous, etc
2. [SB3/user interface] passes orders to Squeezecentre
3. [Squeezecentre] follows up intructions recieved via the SB3, controles the NAS
4. [NAS] does what the Squeezecentre tells it to do, pushes commands/tracks (ie 0101101..) to Squeeezcentre
5. [Squeezecentre] pushes tracks (ie 0101101..) to SB3 device
6. [SB3/user interface] pushes tracks (ie 0101101..) to DAC
7. [DAC] recieves 0101101 and translates it into analoge signal.
All this is connected with a Netgear router and heaps CAT5e cable across the house (when installed I was quite proud everything worked at once, after connecting all those lovely RJ-45 plugs GRBML..).

In this situation I presume the SB3 device with Squeezecentre are the streamer.

I had the following in mind:
1. [Remote/user interface] Controls NAS: browse, select, forward, previous, etc
2. [NAS] does what the remote tells it to do, pushes commands/tracks (ie 0101101..) to DAC
3. [DAC] recieves 0101101 and translates it into analoge signal.
(same as streaming via computer which is directly connected to DAC, but then with user interface remote and out of sight NAS)

In this situation the remote (user interface), NAS (track control) and DAC (understanding 0101101 from Wifi/UTP) have a shared streamer function. Well I thought...

ps. In comparison with printing a MS-Word document.
1. [Keyboard] Controls computer: print, settings color, greyscale, landscape, etc
2. [Computer/user interface] does what the remote tells it to do, pushes commands/documents (ie 0101101..) to printer
3. [Printer] recieves 0101101 and translates it into analoge paper output.

the flaw in your thinking is that a DAC can be a network device - it can't even with this new WiFi model. It will ALWAYS need something to convert the network packets into i2s / SPDIF type data. This is done by a streamer (which could be incorportated into one box ala Linn DS)

Aaaah, there´re two digital signals.

So, the streamer is a ´DDC´ (digital to digital converter), and DAC's start where computers stop. Probably Linn will (have to) update their boxes then, to make them robust for future use (I guess in 10 years time the current/old protocol isn't very familiar any more).

Thank you!

It's more than that as it still needs to supply access to and utilize library info, have features like play lists and artwork and all control functions. It also needs to be a DDDC Winker as compressed and lossless formats need another level of dig conversion.

blimey, yes indeed. Then from recording a track till reproducing it´s converted (thinking in progress.., thinking in progress.., thinking in progress.. ) 6 times!!

notes:
ad master
dd cd
dd flac
dd wav?
dd ie SPDIF
da (c)
