@Max, thanks for posting this one. I contacted someone at The MathWorks about getting an in-person demo. MathWorks is about a 20-minute drive from here.

I've used this toolbox very successfully to demodulate LTE uplink transmissions in signal captured in the field.  It is a great product!

Improving wireless design

Hi Max,

I share the same desire of having ubiquitous wireless communication.  When travelling in remote areas of New England, where I live,  or while going through Boston tunnels, I often wish I didn't lose reception right in the middle of a conversation.

As your chart notes and my experience validates, wireless technologies are rapidly evolving and growing in density, making their design and ultimate success quite challenging. The various wireless technologies need to be engineered and designed to play nice together.

For example, given that our smartphone includes more than one wireless technology – Bluetooth, LTE, and WiFi - engineers need to make sure that they model environmental effects like proximity of user and nearby objects, such as the user's car, to ensure robust transmission and reception. 

Through more reliable engineering design practices, we can all look forward to a future with fewer dropped calls.

What other similar toolboxes are out there that engineers are using for LTE system design? Has anyone tried this tool out yet?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
