HSPA + 64QAM

What is it ? 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 64 QAM ill l b i ifi t i d diti l t th it

Type here level of Sensitivity: “Unrestricted” 15/12/2010 Slide 24

HSPA + MIMO

What is it ?

“M lti l I t M lti l t t”

“Multiple Input, Multiple output”.

Multiple data-streams are transmitted in parallel over different transmit and

i t ’

receive antenna’s.

e.g. 2x2 MIMO (baseline for LTE) means that parallel data streams are

t t t it t ’ d i d b t i t ’

sent over two transmit antenna’s and received by two receive antenna’s.

Benefit :

Cell capacity and average user throughput increase.

Prerequisites: Prerequisites:

(26)

HSPA + Dual Carrier

What is it ?

“D l i ” i bi th i l f t diff t UMTS i

“Dual carrier” is combing the signals of two different UMTS-carriers (or UMTS-frequencies).

S d 8 8 Mb

Speed: 28,8 Mbps

Benefit : Benefit :

Average user throughput increases (only downlink!).

Prerequisites:

Both Radio Access network and the user equipment need to be upgraded. Belgacom has the licence for 3 UMTS-frequencies but is only using 2 until Belgacom has the licence for 3 UMTS frequencies but is only using 2 until now. As from 2011, 3 frequencies will be used.
