Many of the original mobile licences were issued for a specific technology (e.g. GSM or
CDMA) which stops the band being ‘refarmed’ to a more efficient technology (e.g. LTE)
We support a licensing approach that allows any compatible, noninterfering technology
to be used in mobile frequency bands
Technology neutral licences encourage innovation and promote competition, allowing
markets to determine which technologies succeed, to the benefit of consumers
Spectrum identifications for IMT are technology-neutral. IMT technologies including
GPRS, EDGE, UMTS, HSPA, and LTE are standardised for technical coexistence

SPECTRUM HARMONISATION

Adopting harmonised, regional/international band plans for mobile broadband ensures
that interference between services can be managed, and consumers could enjoy a
wider selection of affordable handsets

In the future, more capacity in the extended 850MHz band may be realized through the
development of new harmonized bands, such as band 26 (814MHz – 894MHz) or band
27 (807MHz – 869MHz). These bands are starting to be used in Asia Pacific

 UMTS900/1800 networks can co-exist with other UMTS900/1800 networks
with a carrier separation of 5 MHz;
 UMTS900/1800 networks can co-exist with other GSM900/1800 networks
with a carrier separation of 2.8 MHz;

TECHNICAL STUDIES
 Protection of GSM microcell/picocell from UMTS by separating them with the
GSM macrocell frequency block in between;
 Operator to deploys both UMTS & GSM in the same band is suggested to
use the so-called “Sandwich” frequency arrangement.

TECHNICAL STUDIES
 LTE900/1800 & GSM900/1800 networks
 in uncoordinated operation are recommended to have 200kHz or more
separation between their nearest carrier channel edges;
 in coordinated operation (co-located sites) don’t require frequency
separation at nearest carrier channel edges.
 LTE900/1800 & UMTS900/1800 networks don’t require frequency separation
at neighbouring channel edges;
 No frequency separation is required between neighbouring LTE900/1800
networks.

 Border Coordination – maximum carrier mean field strength value before
coordination is required at borders
