This document discusses re-farming 2G spectrum bands in ASEAN countries to increase spectrum efficiency and support the growth of 3G/4G mobile broadband. It provides background on mobile broadband adoption trends and the importance of harmonizing spectrum bands. Options for refarming 850MHz and 900MHz bands are presented, along with considerations around coexistence of different technologies in these bands. The status and ecosystem around other relevant bands such as 700MHz, 1800MHz, 2100MHz, 2300MHz and 2600MHz is also summarized. The importance of carrier aggregation across bands to further enhance broadband experience is highlighted.

 Due to the overlap between the 850MHz band downlink and the 900MHz band
uplink, there is possibility of inter-band interference
 Mitigation techniques, such as filtering and guard band, can help operators minimize
potential harmful interference
 Qualcomm encourages consultation with the industry to determine the suitable filter
and guard band arrangement at the band edge
 APT AWG Report 53 on Migration Strategy of GSM to Mobile Broadband provides
guidance
 Harmonized allocation, in particularly with neighboring countries, could minimize
potential for cross-border interference and greatly reduce coordination costs

Guard Band Requirement for Various Neighboring Technology
Combinations
Contained in APT AWG Report 53:
Assumptions
(a) At least 60dB isolation between Tx/Rx Antenna
(b) Tx Path has filter for out of band attenuation of around 50dB
(c) Rx Path has filter for out of band attenuation of around 35dB
(d) Edge to Edge Guard Band is defined as separation from upper edge of 850MHz carrier in Tx path to lower edge of 900MHz carrier in Rx
path and does NOT include inherent guard band

Example: Malaysian and Indonesian 850/900 MHz arrangement
Key points of the arrangement:
• “The said band may be used in a
manner whereby different
technologies can co-exist within the
same band thus allowing maximum
utilization of the spectrum “
• GSM base station in-block
transmissions should not exceed +61
dBm EIRP; and
• GSM mobile station transmission
should not exceed 31 dBm EIRP.
• IMT Base Station in-block
transmissions should not exceed +61
dBm/5MHz EIRP;
• On a case to case basis, higher EIRP
value may be permitted if acceptable
technical justification is provided; and
• IMT mobile station transmissions
should not exceed +31dBm/5MHz
