pCell promises speeds 1000 times faster than 4G

Artemis Networks has invented a network technology called pCell, which takes an entirely opposite approach.

Steve Perlman, the CEO of Artemis said that “instead of dodging interference, pCell exploits interference, combining transmitted radio signals from multiple pCell base stations to synthesize tiny “personal cells” – pCells – of wireless energy around each mobile device. So, rather than hundreds of users taking turns sharing the capacity of one large cell, each user gets an unshared pCell, giving the full wireless capacity to each user at once.”

Interesting We need, where do we apply?

In the demo below, Perlman demonstrates a number of situations including four laptops streaming 1080p video on the 10 MHz band over LTE along with two MacBook Pros streaming 4K video and outputting it on 4K TVs. Then he demonstrates 8 iPhones simultaneously streaming 1080p video on the 5 MHz band over LTE.

Giving this a well deserved Necrobump :

Dish wants to be a mobile phone carrier. Dish wants it bad. And Steve Perlman—the genius behind QuickTime, WebTV and OnLive—has spent over a decade working on tech that could allegedly leapfrog our current cell networks. So guess who just teamed up to potentially revolutionize the mobile internet? Yep.

Dish just agreed to lease some of its substantial new wireless spectrum to Artemis Networks, the company that Perlman created to commercialize the so-called "pCell" technology. And with that spectrum, Artemis plans to blanket San Francisco with some crazy-fast, crazy-efficient mobile data. As soon as it can get FCC approval, anyways.

What's so great about pCell, anyhow? It's pretty simple: Where existing cellular networks have to be spaced out to avoid interference, leaving dead zones between them and slow speeds on the edges of each cell tower's domain, pCell claims to actually take advantage of interference by intelligently overlapping wireless signals, creating localized pockets of signal right at your smartphone's antenna. As each phone broadcasts its location, the pCell network figures out what combination of signals the pCell antennas need to transmit in order to add up to a stable connection.

What's more, it can apparently do that trick for loads of phones simultaneously, giving each of them a full speed data connection instead of one connection that gets throttled as the network gets crowded. Here's a demo of that:

How does it do all this? That's a way more complicated question, and one whose answer requires a 99-page white paper to explain.

But as far as you or I are concerned, it could be as simple as sticking new SIM cards into our existing phones and suddenly having amazing signal and speeds. You see, pCell apparently works with existing LTE technology, so nothing needs to be modified on the phone. All the work happens on the mobile carrier side of things. As long as you've got an iPhone 6, iPhone 6 Plus or compatible Android handset, you should be able to give it a go.

But probably not for long, because Perlman says Artemis Networks doesn't plan to be a mobile carrier itself. The company's looking to get existing mobile carriers interested, and this SF trial is designed to show the skeptics that the tech can really work. Perlman actually introduced the idea four years ago under the name DIDO, but it didn't take off. If this time is different, it'll probably get licensed to an AT&T or Verizon or T-Mobile... or maybe even Dish. Who knows.

It wouldn't be the first time Perlman's proven that crazy new tech really works. His last venture, OnLive, wasn't killed by too little tech—but rather too much ego. [

I hope this technology really works. I want my science fiction fantasies to be realisable.

It seems interesting, and based on a white paper I have seen on the underlying tech, it might work. That said, we (Ericsson) spend a massive amount on R&D, and hold something like 50% of all wireless patents. If Ericsson hasn't developed something similar, or made a move to purchase Artemis, then surely there must be something that doesn't quite add up.

My gut feeling, and this is true for all distributed architectures currently, is that there is too much latency in dealing with control signalling in the manner Artemis is proposing. So while this works in a lab environment, as soon as 10km+ of distance is incorporated into the system, the system fails.

Interesting point regarding why they have not been purchased yet. It might also be due to Artemis wanting to get actual real-world testing done before opening themselves up for sale.

Even if you are right about latency over long distance, their demonstrated tech is still impressive. Particularly their indoor location system, which seems to be a minimum requirement for their system to work. Google would be interested in them only for that.

Also their tech also serves as a nice way to demonstrate the capabilities of software defined radio.

edit:
DARPA has also been doing some research into this tech for it's military uses. So I guess it must be usable outside.

Is the info in these forums legit?

Yes very legit, trust all users here. All users are tested on a lie detector before their 100th post.:whistling:

There is a white paper by Artemis that goes into the technical details. There is also a paper on the DARPA work.

Got a link for this? I read this a few years back, not sure how its progressed to be quite honest.
