WHAT SPECTRUM EFFICIENCY CAN BE ACHIEVED IN LTE ?

Shares

Spectrum efficiency is defined as the number of bits transferred per second per hertz (bits/s/Hz). For LTE, Spectrum efficiency targets were formulated relative to comparison with Release 6 of (WCDMA) HSPA baseline system.

For Uplink

LTE Uplink can achieve 2-3 times improved spectrum efficiency as that of Release 6 HSPA (WCDMA)

For Downlink.

It can achieve 3-4 times better spectrum efficiency than HSDPA (WCDMA)
