MESSAGE OF THE CHAIR OF THE WORKING GROUP TO QUANTIFY ANY INCOMPATIBILITY
ISSUES BETWEEN FWA AND PCS
IN THE RANGE 1850-1990 MHZ

Mr. Héctor Budé

At the meeting held in Mexico City in August 1995, the Permanent Consultative Committee III
(PCC.III) began work on recommendations concerning the allocation of spectrum in the 1900 MHz
band, and since then has produced documents such as recommendations 11/95 and 12/95 which deal with
so-called Personal Communication Services (PCS). Subsequently, it was observed that certain
administrations were using fixed wireless access technologies on that frequency band, and it was felt that
it was important and appropriate to quantify any incompatibility between Fixed Wireless Access Systems
(FWA) and Personal Communication Systems in the 1850 - 1990 MHz range.

That task began in December 1996, and, since it involved various aspects and was not a purely
technical initiative, there was a slight possibility that there would be some delay in obtaining the results,
as did in fact occur.

Today, however, all participants who have directly and indirectly assisted–firms and
administrations–can see that the effort was productive. Although not everyone, particularly the firms, is
satisfied with it, this report should be consulted by administrations when they evaluate the allocation
spectrum for various technologies on the 1850-1990 MHz band.

I therefore wish to thank all participants for their dedication and collaboration in preparing this
document. To the Vice Chairs of the Working Group, Mr. Michael Lynch (Nortel) and Mr. Marco
Rodolfo Perez (Ericsson Colombia), and the experts, a special vote of thanks.
