In the first debates of the 2019 World Radiocommunication Conference (WRC-19), the group that discusses how earth stations in motion (ESIM) will work held about five meetings, to discuss the ten main issues on these artifacts. Two very clear and distinct positions about aerodynamic ESIMs were evidenced: on the one hand, Korea and Iran (with some contributions from Japan) consider that PFD masks are not viable to protect the ground services of the aeronautical ESIM; while other countries and regions do support these PFD masks.
Item 7 of the WRC-19 agenda, focusing on satellite coordination procedures, is addressed by a group chaired by Jack Weyngrynic of the United States. In the first days of debate it was shown that the theme will held until the end of the conference, since there is no consensus in sight even among current proposals.
Regarding agenda item 1.13, presidents were identified for the different drafting groups. DG4A1a will be led by Luciana Camargos, from Brazil, whose main problem to be approached is the limit for protection in the 23.6-24 GHz band. Meanwhile, DG4A1b, in charge of Hiroyuki Atarashi (Japan), shall address as main issues which parts of the bands will be identified for IMT (37-40.5 / 40.5-42.5 / 42.5-43.5 GHz), and consideration of protection in these bands. The DG4A1c, chaired by Kenneth Concannon (Ireland), addresses the identification of the 66-71 GHz band.
In addition, to accelerate work on the most controversial point of the conference, it was agreed to discount the 31.8-33.4 GHz (band B) and 47-47.2 GHz (band G) bands, for which contributions proposed "no changes" (NOC).
In turn, it was decided to divide the documents on 28 GHz and 31 GHz, in order to facilitate global support for 31 GHz, while the 28 GHz band is still under discussion.
With regard to WiFi in 5 Ghz, an NOC agreement was reached for the bands 5,250-5,350 MHz, 5,350-5,470 MHz and 5,850-5,925 MHz with respect to the identification of WiFi (mobile service). Meanwhile, the bands 5,150-5,250 MHz and 5,725-5,850 MHz remain under discussion.
