HSPA + 64QAM
What is it ?
64 QAM
= modulation scheme
= method to put more bits into a transmitted signal
Speed : 21 Mbps.
Application : Indoor microcells (e.g. Zaventem Airport)
Benefit :
With 64QAM, it is possible to deliver 6 bits in one transmitted burst.
In 16QAM, we can transmit 4 bits.
Prerequisites:
Both Radio Access network and the user equipment need to be upgraded.
Constraints
The more bits in 1 signal burst, the more the signal must be undisturbed.
Th f
Therefore
64 QAM will

t t”
Multiple data-streams are transmitted in parallel over different transmit and
receive
i antenna’s.
