] The FCC press release (in PDF format, no HTML) said that
] 255 MHz in the 5.470-5.725 GHz band are now available for
] unlicensed devices. This action will also harmonize the
] spectrum available for these U-NII devices throughout the
] world, enabling manufacturers to reduce product
] development costs by allowing the same products to be
] used in many parts of the world.
]
] The FCC is also requiring the items covered in IEEE
] 802.11h, which was developed to conform to European/World
] Radio Congress concerns, also apply to the lower indoor
] bands of 5.250-5.350 GHz as well as the new 5.470-5.725
] GHz bands: dynamic frequency selection (DFS) - a
] listen-before-talk mechanism — and transmit power
] control (TPC).
]
] That additional 255 MHz should translate into as many as
] 12 additional nonoverlapping channels for 802.11a, which
] already has 12 nonoverlapping channels. In a talk with
] Atheros that Glenn had recently, the company noted that
] bonding channels in 802.11a to create multiple channel
] throughput of 108 Mbps or higher has enormous potential
] because of the lack of channel overlap.
