Coverage Comparison b/w HSPA+ and LTE
n LTE 2.6G has much better coverage in DL than HSPA+ 2.1G; But HSPA+ 2.1G has better coverage in UL than LTE 2.6G.
n LTE can reuse existing 3G sites, no additional LTE alone sites are required at the beginning of LTE deployment.

Advantagesü No need additional space for
new antenna .
ü No or Small impact on
performance of existing network.
Disadvantagesü Require more feeder installation
space.
ü Replacing new antenna.
ü Independent tilt but same azimuth,
partly independent network planning
and optimization.
Recommendationü New antenna should keep same
beam width and gain for least
negative impact on existing
network.

Typical Co-location Scenario - Shared Antenna & Feeder (2)
Existing 2G/3G 2G/3G + LTE
Advantagesü No need additional space for
new antenna and feeder.
ü Reusing existing feeder.
Disadvantagesü Replacing new antenna or existing
antenna is wide band.
ü Same tilt & azimuth, impossible
independent network planning and
optimization.
ü Additional diplexer cost and loss,
negative impact on existing network.
Recommendationü New antenna should keep same
beam width for least negative
impact on existing network.
ü It ‘s not recommended if other
solution is applicable.
