RE: stds-802-16: sub10. On the Frequency Bands of Interest for 802.16.sub10

Vicente Hi!
As was noted by a number of contributions in our previous IEEE 802.16
meeting, for the standard-based >10GHz BWA equipment to be successful their
cost must be low, because price will highly affect the deployment.  I
believe that most participants agreed with this.  I believe that this cost
issue also holds for the sub10 BWA equipment, and I am assuming that most
people will agree with me.   One aspect that will minimize the cost of the
sub10 equipment(on economy of scale basis) is to establish maximum
commonality of all the sub10 bands equipment, licensed and unlicensed.    
Moreover I do not agree with your statement Vincente that
     "Unlicensed bands might  be considered as well, although with minor 
     priority, as their use for public applications is doubtful for the 
     reasons mentioned above, while on the other hand private applications 
     are already covered by suitable, consolidated  IEEE 802 standards" 
as a number of our customers are either using, or plan to use, the Adaptive
Broadband's TDD BWA equipment in the unlicensed 5GHz band for public
applications.  So I find no good reason for discriminating between licensed
and unlicensed bands standardization.  I can give some good reasons why
unlicensed bands equipment should be standardized with priority, but then we
would not be minimizing the equipment cost.

Best Regards
Demos

802.16.sub10



     Seen from the business viewpoint, there is at the moment a big 
     interest in wireless point to multipoint solutions for  SoHo and 
     high-end residential segments, for the provision of data traffic, in 
     particular access to Internet and Intranets, LAN-to-LAN 
     interconnection and data-based VPNs.
     This is derived from several aspects, such as the de-regularization 
     process around the world and the enabling of suitable, cost-effective 
     wireless technologies for those services and applications.
     To suit these solutions, operators are looking for licensed frequency 
     spectrum bands, as a way to have control of the volume of 
     infrastructure required and proper offering of Quality of Service to 
     their customers.
     
     It is therefore advisable to consider as high priority within the 
     scope of IEEE 802.16sub10 the most important licensed frequency bands 
     identified below 10 GHz, specifically the (2.5-2.686) GHz US MMDS band 
     and the (3.4-3.7) GHz CEPT band
     
     Unlicensed bands might  be considered as well, although with minor 
     priority, as their use for public applications is doubtful for the 
     reasons mentioned above, while on the other hand private applications 
     are already covered by suitable, consolidated  IEEE 802 standards
