True 100mbp/s WLANs on the horizon

From desktops to laptops to mp3 players to media centers, wireless is becoming a big part of computing, moreso with more houses having multiple computers. Many are turned off by it, though, due to very slow transfer speeds as compared to wired connections. MIMO is a newer technology designed to give wireless LANs a larger area and fast speeds. “Multiple Input, Multiple Output” has been developed by multiple partners, though Airgo Network is getting much of the credit for their work. Cisco and others are starting to include their technology in their products. It works by letting a wireless device, say a laptop, to use multiple datastreams on multiple receivers simultaneously. It potentially results in a tripling of available bandwidth. Other companies that produce competing chipsets are developing similar technologies. Atheros, one of the most popular wireless chipset producers, is using multiple antennas and multiple radios to broadcast the same datastream, slightly different but still effective.

Ultimately, this means much faster wireless for everyone available soon, perhaps within a year. The 802.11n standard, unfinalized as of yet, will bring a true 100MBp/s wireless network solution to the market that has wider ranges without needing to be amplified to extremes, with a 500' radius feasible. Once wireless connections are truly able to match the majority of home wired connections (100MBp/s Full Duplex, for instance) and in price, the only area left is security. But what an area that is.

  1. This reminds me of P2P technology which may be where the idea stemmed. I like this idea as I have very little need for wireless security in my home network setup. Though, I feel businesses may have a different take on it when needing to secure their high risk data. We'll have to see how it plays out.
  2. I don't think this is exactly like a P2P client. It would be more apt to be compared to a download manager like GetRight.I think what they are suggesting is that instead of broadcasting one signal on one frequency band, the antenna would broadcast multiple signals on a wider band of frequencies. For example, if one were sending a file, it would be divided into x number of parts, and each part would be broadcast over a different frequency band, all at the same time. Even though each individual broadcast is only at 11Mbps (or 54Mbps if it is a 802.11g type transfer speed) the total speed of the connection would be the transfer speed multiplied by x (from above, the number of simultaneous broadcasts)Although this does serve to increase the speed of the transmission, it does raise an interesting question about congestion. There are only so many frequency bands available, many are regulated by the government, others are very prone to interference. So if and when this is implemented, and every wireless computer is consuming as much frequency bandwidth as 10 computers are now, we could have some very interesting conflicts over frequency range rights.Who knows, in the future property laws may have to be re-written so that you also own the rights to a certain frequency bandwidth in an area around your physical property. It will indeed be interesting to see how this plays out.
  3. Yeah, alot of people have been turned off by the slow transfer speeds, including me. This however, changes my mind about how I look at wireless connections. It's nice to see that they are getting drastically faster than before. It would make a big improvement at my parents work shop. They don't have alot of laptops, but wires are going every way you can think of. They never really considered the wireless thing, hence it's slowness. Bottom line is, this would make a huge improvement with anyone that wants to go wireless.
  4. Sounds like it would only work in areas covered by multiple wireless routers/access points, though, not for the typical home which is only covered by one.The lack of speed doesn't pose as much of a problem when the wireless access is only used to browse the internet, as typically even an 802.11b card would saturate that kind of connection except in the case of a big campus or corporate office with a T3 or something along those lines.The cable at my old house was 4mbit down, so it was easy for me to experience full speed internet connectivity even on my old 802.11b integrated wireless computerI can see the advantage that these improvements would pose for an intranet comprised of many wireless devices, though, such as hospitals and other vertical markets.

The access point has several antennas, but it's still only one access point. And there are a whole lot of different ways to utilize the speed, for example LAN games and large data transfers. U wouldn't want to play Warcraft with ur friends, or transferring a DVD movie u downloaded from the internet, on a 10MBps.
  6. I like the idea of wireless because wires isn't useful anymore. Wireless is the way forward, as are laptops though your opnions on THAT may vary. However, i like the way the title says "true" lol but the fact is that this type of technology is always a double-edged sword. On the one hand you have no wires, good speed and decent price but on the other hand you have congestion and perhaps a drop in performance as its popularity increases because of this.
