LTE-Advanced, the new communications test standard for mobile device manufacturing offers you the latest and greatest for your wireless design but does it add too much complexity?

LTE Advanced key features

Some of the main headline aims for LTE Advanced are:

1.Peak data rates: downlink - 1 Gbps; uplink - 500 Mbps.

2.Spectrum efficiency: 3 times greater than LTE.

3.Peak spectrum efficiency: downlink - 30 bps/Hz; uplink - 15 bps/Hz.

4.Spectrum use: the ability to support scalable bandwidth use and spectrum aggregation where non-contiguous spectrum needs to be used.

5.Latency: from Idle to Connected in less than 50 ms and then shorter than 5 ms one way for individual packet transmission.

6.Cell edge user throughput to be twice that of LTE.

7.Average user throughput to be 3 times that of LTE.

8.Mobility: Same as that in LTE

9.Compatibility: LTE Advanced shall be capable of interworking with LTE and 3GPP legacy systems.
