Following new security measures implemented in ITU in early August 2005, no one without a valid badge will be admitted into the facilities.

6. Registration and VISA Information ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To register your meeting attendance, please send e-mail to Seong-Ho Jeong shjeong@hufs.ac.kr, providing the family name, given name, company name, address, country name, phone number, fax number, e-mail address of person(s) attending. Every participant should use the registration form at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Regist ra tion_form.doc.

Early registration of your attendance is welcome and encouraged, but preferably before 18 November 2005 to facilitate the production of badges for all participants. People needing visa support letters (see below for requirements) should register as soon as possible.

We would remind you that citizens of some countries are required to obtain a visa in order to enter and spend time in Switzerland. The visa must be requested and obtained from the office (embassy or consulate) representing Switzerland in your country or, if there is no such office in your country, from the one that is closest to the country of departure. If problems are encountered for ITU members, the ITU can, at the official request of the administration or company you represent, approach the competent Swiss authorities in order to facilitate delivery of the visa. Visa requests should be made by official letter from the administration or company you represent. This letter must specify your name and function, date of birth, passport number as well as the date of issue and expiry. The letter must be accompanied by a photocopy of your passport and completed registration form and must be sent to TSB, bearing the words "visa request", by fax (No.: +41 22 730 5853)

or e-mail (tsbreg@itu.int). Please note that ITU needs at least one week to process all papers required for the delivery of a visa. For the ones needing this letter, TSB should receive a meeting registration form which can be found at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Regist ra tion_form.doc.

7. Hotel Room Reservation ^^^^^^^^^^^^^^^^^^^^^^^^^

Participants should contact the hotels directly regarding room availability and for making room bookings. Hotels offering preferential room rates for participants of ITU meetings are found at: http://www.itu.int/travel/index.html. An appropriate hotel reservation form can be found at: http://ftp3.itu.int/av-arch/avc-site/2005-2008/0511_Gen/0511-WP2-16-Hotel- re servation-form.doc. Please note that this hotel reservation form must be used in order to be able to get the special ITU rates.

Note: the closest business-class hotel to the ITU buildings is the Intercontinental, and a more popular strategy is to obtain hotel accommodations downtown, e.g., near the Cornavin train & bus station (which is more centrally located than the ITU or the Intercontinental), from which buses run frequently to the vicinity of the ITU. Not all hotels are equipped with high-speed internet access, so you participants may want to check with the hotel for the availability of this service.

We are looking forward to meeting with you in Geneva.

Sincerely yours,

Patrick LUTHI Paul JONES Christian GROVES Sakae OKUBO (document manager of this meeting) Bastien LAMER Noah LUO Seong-Ho JEONG (meeting organizer of this meeting) Martin EUCHNER Leo LEHMANN
