Mobile broadband drives subscription growth


Globally, for several years, the most common way to access the internet has been over a mobile network

North America

for mobile broadband, population coverage is currently at around 80 percent and forecast to grow to over 95 percent in 2023

it took just 5 years for LTE to cover 2.5 billion people, compared to 8 years for WCDMA/HSPA

with the expected growth of IoT services, there is a higher demand on geographical coverage5G coverage will commence in metropolitan and urban areas

Affordable access to spectrum for 5G- Fundamental to society

Preference is for dedicated licenses Auctions represent a fair regime by providing a rational market value of

dedicated exclusive spectrum to users who value it the most; therefore auctions• should be designed to stimulate maximize spectrum usage• should be designed to maximise benefit for society• should be designed to stimulate investments in infrastructure• should not be designed to maximise revenue

Greatest benefit to society (e.g. increased GDP) is in its sustained use

Simultaneous access to low, mid and high bands will be needed to meet 5G requirements and use cases

Expeditious and timely regulatory action is needed, to make available the existing harmonized mobile bands suitable for 5G

Affordable access to spectrum is fundamental to users; greatest benefit to society from spectrum (e.g. increased GDP) is in its sustained use, not from revenue‐based auctions

5G represents a new communication paradigm

Background of WRC‐19 Agenda Item 1.5 (ESIM)

• Mobile 5G operation in 28 GHz (26.5 – 29.5 GHz) overlaps the E‐s portion of the Ka‐band under consideration for ESIM under WRC‐19 agenda item 1.5

• Three types of ESIMs are envisaged to operate under FSS allocation:• Land‐based (connectivity for trucks and other moving vehicles)• Air‐based (connectivity for airplanes)• Sea‐based (connectivity for ships and boats)

• In the US, ESIM and 5G are in adjacent bands (ESIM above 28.35 GHz) but in other countries there could be a full overlap in the entire 2 GHz (27.5‐29.5 GHz)

• Mobile and FSS are co‐primary in RR (in the US FSS is secondary)

ESIM Coexistence Conditions

• Air‐based (ESIM‐A)• ESIM antenna mounted on the fuselage tracking the satellite• Corresponding 5G deployments are:

• 5G in urban/suburban areas near the airports; hotspots at the airports; airport facilities using 5G• Interference more likely at low‐altitudes and on the ground (parked‐taxi)

• Sea‐based (ESIM‐M)• ESIM antenna mounted on a mast tracking the satellite• Corresponding 5G deployments are:

• 5G hotspots in urban/suburban areas near the pier; shipyard facilities• Interference more likely in docked situation or short distances to the port

• Land‐based (ESIM‐L)• ESIM antenna mounted on the roof of a truck, train, etc.• Corresponding 5G deployments are (both inter‐city and intra‐city):

• Hotspots in urban/suburban areas; V2X connectivity on highways in urban/suburban/rural area• Significant interference expected in most cases with potentially very short distance

• Aggregation of ESIM interference could be a considerable factor in all cases

Protection of the Mobile Service from ESIM‐ maximum allowed PFD regime should apply to ESIM

Phased array beamforming nature of the MS antenna makes it difficult toCalculate an PFD envelop for all AZ/EL angles, hence maximum allowed PFD

Mobile industry view from studies in WP4A

• Must take into account mobile service characteristics agreed by WP5A (System A, System B)

• Overall, co‐channel studies so far point to potential for serious interference when ESIM TX operates in close proximity to MS RX in all three cases

• Adjacent channel study is also important due to cases such as the US, as well as potential for band segmentation as means for sharing the band

• Best solution for protection of the MS seems to be through establishing ESIM PFD by taking into account MS characteristics

• Mobile industry is of the view that ESIM‐L is the most critical source of interference to 5G operations. No mitigation solutions have been proposed by ESIM proponents.

Issues on 28 GHz band at WRC‐19

• WRC‐19 Agenda Item 1.5 (ESIM)• Studies to consider the use of the bands 17.7 – 19.7 GHz(s‐E) and 27.5 ‐29.5 GHz (E‐s) by earth stations in motion communicating with GSO space stations in the FSS and take appropriate action (Res. 158(WRC‐15))

• WRC‐19 Agenda Item 1.14 (High Altitude Platforms, HAPS)• Studies for considering appropriate regulatory actions for HAPS , within existing fixed‐service allocations at 47.2‐47.5, 47.9‐48.2 & 31.0‐31.3*/27.9‐28.2 *GHz(* Outside Region 2 + 5countries at 6.5/6.5MHz),

HAPS Studies in WP 5C (1/2)

• Some deployment scenarios extended now also to urban and suburban areas

• Meanwhile, Resolution 160 (WRC‐15) clearly mentions that• HAPS for providing fixed wireless broadband connectivity in remote areas, including mountains, coastal

and desert areas;• Existing services and their applications shall be protected from HAPS applications, and no undue

constraints shall be imposed on the future development of existing services by HAPS;• the studies include sharing and compatibility studies to ensure protection of existing services

HAPS Studies in WP 5C (2/2)

• System characteristics have been significantly modified. E.g. • New power control concept to reduce current max EIRP by up to 35 dB.

• Considerations for some systems to extend radius of HAPS service coverage from 50 km to 200 km

• Mobile industry is of the view that HAPS service using same and/or adjacent bands with 5G should only be implemented if co‐existence is possible with 5G mobile service !

• Any identification for HAPS should include regulatory provisions for the protection of terrestrial 5G. This can be achieved through setting PFD limits on HAPS.
