La FCC determina que la banda de 3650 a 3700GHz és d'ús lliure.

La FCC ha resolt que la banda dels 3650 a 3700GHz se'n pugui fer ús des de les comunitats sense fils. El document és aquest:

Amb la incorporació d'aquesta nova freqüència, la FCC espera aconseguir que les comunitats de xarxes sense fils es desenvolupin millor. Un pas endavant que esperem que es vagi complementant amb la incorporació de noves frequències, tamble a la banda de prop dels 900MHz, amb un ampli ventall de freqüències que permeti combinar amb comoditat i eficiència els diferents tipus de connexions necessaris pel desplegament d'aquest tipus de xarxes.
Val la pena reproduir les consideracions (an anglès) que ha publicat en Jonathan Adelstein, un dels comisaris de la FCC, sobre aquest assumpte, on destaca que l'importància de la creativitat des moviments de les comunitats que fan xarxa sense fils i l'impacte positiu que comporten.

A little over two years ago, I was very pleased to support the
Commissions innovative decision to make the spectrum in the 3650-3700
MHz (3650 MHz) band available on a licensed, but non-exclusive, basis.
In many respects, this was a bold statement. We wanted to take advantage
of the success of the WiFi movement and take it to another level. We
wanted to find the right balance between a licensing model for
traditional, area-wide mobile systems and a model for unlicensed,
consumer-based services. Our licensing regime for the 3650 MHz band will
serve as a wireless highway between small towns and the big city it will
facilitate the delivery of broadband to all corners of the country by
serving a different user group, one that often is driven by more
localized, community based needs.

Since our initial decision, I have talked often about the public
interest benefits of the new licensing rules for the 3650 MHz band. I
have spoken with many supporters of our decision, and with those who
believe the band would be better used on an exclusive basis. But I
remain convinced the hybrid licensing approach that we first adopted for
the 3650 MHz band is the correct one, and I enthusiastically support our
reconsideration order today.

During my time at the Commission, I have pushed for flexible licensing
approaches that make it easier for community-based providers to get
access to wireless broadband opportunities, and the rules we affirm for
the 3650 MHz band should help make wireless broadband services available
to a large number of new users. Today, we uphold our earlier decision to
put in place a regime that doesnt rely on first in time and provides
equal access to all. I have heard from representatives of the Community
Wireless Network movement about our 3650 MHz licensing rules, and they
are thrilled with the hybrid approach and the positive impact it will
have on their efforts to deploy broadband networks in underserved
communities around the country.
 
So, once again, I wholeheartedly support our 3650 MHz licensing
decision. Of course, only time will tell if this unique approach will
result in increased use of this spectrum band. But I think that given
the success of unlicensed wireless networks, we are on the right track,
and our creative spectrum management approach is well justified.

Parlem de 50MHz? aixó crec

Parlem de 50MHz? aixó crec que es l'ample de banda d'un sol canal wifi actual.

Les bandes licenciades de 23-26GHz tenen canals de 150MHz Sticking out tongue

entenc que si, 2/3 canals reals...

Depèn de la separació que posem de canals, però si pensem que la separació és entre 15MHz i 20MHz, 2 o 3 canals.
Similar al que passa als 2.4GHz

Adaptació de les normatives

A veure com els legisladors europeus i de casa nostra adapten aquesta determinació de la FCC per a poder-la usar.

Ja podien pendre nota per

Ja podien pendre nota per aqui de desicions com aquestes que en comptes de anar posant pals a les rotes el que fan es fomentar i posar mitjans a les xarxes sense fils Eye-wink
