5G Fixed Wireless Access (FWA) will be one of the earliest uses of 5G. 5G FWA will provide lightning fast gigabit internet speeds to homes, apartments, and businesses. Better yet, 5G FWA will be a fraction of the cost compared to traditional cable & fiber systems.

Fifth generation wireless systems are not far from becoming a reality, thanks to recent research being done on the millimeter wave (mmWave) radio spectrum.
Experts agree the way forward is to manufacture mass deployable wireless devices across a range of markets and for different applications. Among other things, these applications include mobile computing and data processing over networks. The technology also has applications in the field of medicine and healthcare.

Three Erie companies will manufacture the shields, creating 5,000 every day
Bliley Technologies has partnered with researchers at Penn State Behrend and Case Western Reserve University to fulfill and distribute a face shield for medical professionals who are treating patients who have the COVID-19 virus. They expect to produce nearly 240,000 shields.
Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.

Maintaining strong frequency stability in electronic RF circuits by eliminating phase noise is important in many high-end communication applications. This is especially true for precise targeting in radar systems and spectral purity in other communication systems.
Let's take a deep dive into exactly what phase noise and jitter mean. This will help give you a better idea as to why reducing a system's phase noise is significant.
In the simplest terms, phase noise describes the stability of an oscillator in the Frequency Domain, while jitter describes stability in the Time Domain.
Step 2: When plotting each spectral density point at varied frequency intervals of your choosing (In this case every 1Hz), you're left with a graph that looks like this:
You are now looking at what is known as the Signal Power Density of the noise.
Now focus only on the upper sideband of the graph from fstart to fstop, this is called the "Single Side Band".
We can now refer to the plotted part of the single side band as noise (Anything above the nominal oscillator frequency (Fosc) and not harmonically related can be considered phase noise). The technical term for this part of our graph is Noise Power Density (Step 3). We measure noise power density in dBW (LOG(Watts)) at this point because of the large range which we are looking.

Our engineering team at Bliley is growing, which is great, but it also introduces some new challenges for small business like ours... finding the best performing engineering laptops for our engineers.
We want to give our engineers the best tools available and create an environment where they can be their most innovative and do the best work of their careers. Of course, a key to this whole equation is the technology they use day-to-day to get those next generations products designed. We recently kicked off a search for the best laptops that are perfect for engineering workloads. As you can probably imagine, the ideal laptop for an engineer needs to have great compute and graphics power.
