Re: Spectrum crunch: not a problem today, but eventually said by Guspaz:There's a fixed amount of wireless spectrum available, and there's a theoretical maximum amount of data that can be pushed through it. That's a laws-of-physics type limitation, no new wireless technology will ever relieve us of that limitation. You are missing one parameter: fixed amount of bandwidth within a given cell. Reduce the cell radius by half, you can now reuse the same spectrum up to eight times as often (3D space) and you can repeat the process until you reach the smallest practical cell size such as pico-cells (50-200m range) embedded into incumbent modems/ONTs/CPEs turning every wired subscriber into a wireless cell for the incumbent's own wireless network.
For now, incumbents are sticking mainly to femto-cells (~10m range) due to the technical challenges of maintaining accurate frequencies over time but this will probably change once a cost-effective and reliable solution is found. |

| Stop hd video or stop all video. I have no problem with stopping all video downloading on cell-network's. You-tube 4 billon download's a day not all on mobile network's but proly half. Let the fire storm/flaming begin. |

Re: Spectrum crunch: not a problem today, but eventually said by Skippy25:Fixed or not, improvements or not, there is one thing for sure. There we NEVER be an exoflood as networks will always work themselves out That depends on whether or not peak-hour usage will start tapering off before catching up with hardware capacity growth.
If you read Cisco VNI and other similar reports, some types of peak-hour usages such as video streaming grow by 50-60%/year. On the other hand, large routers's capacity/density/cost improve at a rate of about 25%/year.
Whether or not the exaflood will happen depends on whether or not demand will catch up with hardware's head-start before slowing down. |

Re: Spectrum is finite Its no myth. You can't change the laws of physics. We've seen what happens when no limits are placed on usage. |

Re: Siri is causing capacity problem on wireless networks Good thing only one person owns a iPhone. Imagine what would happen if millions had one and used it at the same time. |

Re: Stop hd video or stop all video. Bandwidth is not Finite Nor is spectrum, a companies lack of willingness to upgrade and improve infrastructure is this brick wall. If you follow a natural technology progression 20 years ago a 900baud modem was as fast as most thought we could go. Today I type this on a residential 100/50 fiber to the home connection. The same can and should be said about radio waves and the ability's to efficiently use them. While it seems uncommon now to do most everything over a cellular network for most bandwidth needs. Video's, games, content, media in general will continue to increase and technology will adapt to make more efficient use of market required needs. Until the market demands a substantial shift in the way business is done. Legacy companies will continue to cry foul and waste more money spinning arguments trying to convince the masses that increased cost and less service is needed for the good of the network. To be honest in a dream world most companies would love to charge you for not providing a service and continue to raise rates when they literally do nothing for you. Stockholders will never be satisfied with a 100% profit margin the market will continue to want increased profits quarter by quarter. |

Re: Spectrum crunch: not a problem today, but eventually said by battleop:That can be done but equipment, towers, and engineers are not cheap. Most of the engineering is about picking locations, prepare mounting arrangements and getting uplink/power on-site. You have none of those problems with embedded pico-cells in subscriber CPEs since the wired subscriber provides all of the above for free... doesn't matter if individual pico-cell placement is sub-optimal if you have many times more cells than you need to handle demand. Worst case, you turn off some cells where there is excessive overlap. |

Spectrum is a finite quantity. Period. |

Still there. nobody wants to pay to light it up. |

Re: Spectrum crunch: not a problem today, but eventually said by Alex J :Story above pretty clearly highlights Cisco's predictions are inflated. Two guesses why. One should be "to sell hardware." Try looking around for companies that publish statistics about their usage growth that go into comparisons between average and peak traffic growth, they all agree with numbers similar to Cisco's... 30-35%/year average, 50-60% peak.
You do not need to believe Cisco, Sandvines, Akamai or anybody else, just visit the statistics pages from any internet exchange, they all show similar trends as well.
Here are the stats page from two of the largest internet exchanges in the world:
»www.ams-ix.net/statistics/
»www.hkix.net/hkix/stat/aggt/hkix···ate.html
That 50-60% does not only exist in Cisco's and other equipment manufacturers' papers, it also exists in the real world. |

Re: ipv4 vs 6 said by hahahehehoho:ask the federal us govt how many million upon hundreds of millions of ips they have for what?
and then you see what they are doing eating them up forcing this v6 at everyone to make a buck...why the fbi alone has 120 million dedicated for just honey potting i hearzzzz
Sigh... why is your completely irrelevant conspiracy theorist comment hogging up the top spot on this article? |

Do you live in an alternate universe that doesn't have our laws of physics or something? Spectrum is a finite quantity. Period. Uh no, spectrum within a cell tower radius is finite. You can add as many cells as you want, and string up fiber to those cells as needed. In 5-10 years Verizon will be able to leverage FIOS to set up a hetnet. |
