WRC 2019 Agenda Item Details
| Agenda Item: | Agenda Item 9.1.1 |
| Resolution(s): | Resolution 212 (rev. WRC-15) |
| Description of work: | This relates to the implementation of IMT in the frequency bands 1 885-2 025 MHz and 2 110-2 200 MHz. The Resolution invites the ITU-R to study possible technical and operational measures to ensure coexistence and compatibility between terrestrial and satellite components of IMT, in particular in the frequency bands 1 980 - 2 010 MHz and 2 170 - 2 220 MHz. |
| Comments: | These bands were proposed to be used by the non-GSO MSS system ICO Global Communications (amongst others) but it only launched a single satellite. |
| Lead Working Party(s): | WP 4C |
| Involved Working Parties: | WP 5D |
| How Visualyse products can help: | Visualyse Professional can model both terrestrial IMT and also the satellite component of IMT, whether GSO or non-GSO. In either case it can model the uplink and downlink and any combination of sharing direction. It can also model hybrid systems, i.e. satellite IMT with a terrestrial component, and model both co-frequency and non-co-frequency scenarios. Terrestrial scenarios can be modelled using a range of propagation models including Hata / COST 231 or P.452, P.1546, P.1812, P.2001 using terrain and/or land use data. Satellite systems can be imported from the ITU IFIC/SRS database or generated using constellation wizards and use Earth to space propagation models such as Rec. P.618 and P.676. |
| How Transfinite consultants can help: | We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at the ITU-R WPs. Using our in house Visualyse Professional we can quickly model a very wide range of systems, services and scenarios. |
