Addressing frequency fragmentationin the industry

Mobile Broadband growth

Great take up but to sustain growth, capacity demands need to be met – requires technical advancement and more spectrum.

Worldwide spectrum availability

There are multiple bands for LTE as defined by ITU - both paired and unpaired

US/Canada700, 850 MHz

1.7/2.1, 1.9, 2.5 GHz

Europe800, 900 MHz

1.8, 1.9/2.1, 2.3, 2.5 GHz

Asia-Pacific450, 700, 850, 900 MHz

Africa & Middle E.450, 800, 850, 900 MHz

1.8, 1.9/2.1, 2.5 GHz

Latin America450, 700, 850, 900 MHz1.7/2.1, 1.8, 1.9, 2.5 GHz



What is the issue ?

Fragmentation of spectrum allocations is bad for industry as a whole

Devices need to support multiple bands for single markets

Devices need to support further bands to allow for international roaming

Benefits that consumers have gained so far in affordable devices will belost


RF component costs increase with number of bands – impacts device,network and spectrum acquisition

Leads to multiple chipsets in the industry

some expensive but supporting all bands – generate scale but cost is high

some cheap but supporting limited bands – implies smaller addressablemarket and inability to roam to some regions

GSMA supporting the harmonisation of spectrum

This in practice means regional harmonisation

Devices can handle a limited number of frequency bands

GSM, UMTS/HSPA, WiFi, Bluetooth, LTE in the near future

Support for Roaming

Each technology normally has a capacity and coverage band(900/1800 or 850/1900)


Inclusion of multiple bands may affect filter design (duplexer)leading to loss on link budgets (hence reducing coverage and ormax through-put)

Without addressing the band aggregation issue, the developmentof mobile broadband might be hindered due to problems withdevice design



Current global status of UHF at a glance

Region 1Europe:790-862 MHz

Possibly extend down to698 MHz?


Region 2USA:698-806 MHz

Region 3Focus in Asia on698-806 MHz

Population 3.7 billion



Conclusions

Fragmentation of spectrum allocations and band plans across theindustry damages the mobile telecoms ecosystem

There is a need to promote frequency harmonisation to ensure thatuser devices are affordable and work efficiently especially whenconsidering roaming


The GSMA works with regional bodies like CITEL and APT/AWF aswell as ITU to promote this in an effort to minimise the number ofband plans

Alignment across as wide a geographic area as possible promotesscale and consumer choice by lowering costs per unit and allowing agenuine ecosystem to develop
