Status LTE1800


[from GSA]

Advantages of LTE1800



Coverage area 2x

compared to deploying in 2.6 GHz band



Possibility to
re
-
use assets
including antenna cables of GSM1800



Possibility to
deploy multi
-
RAN
with simultaneous LTE and GSM capabilities



Operators often have
sufficient bandwidth

in 1800 MHz to secure full benefits of LTE



Often
easier to re
-
farm

than 900 MHz



User
device eco
-
system

is building; a good choice of user devices by end 2011



Can be a
transition strategy

between HSPA and availability of new spectrum

Broadband Infrastructure Development

Summary


Broadband requires
significant investment
in Transport Network Infrastructure


LTE1800/2100 can be used

in interim to provide last mile for broadband


Dedicated and sufficient LTE spectrum
to be made available to support higher
speeds (180 Mbps DL requires 2x 20
Mhz
)


Lower Frequency

can reduce significantly number of LTE sites
