What Skills are Required to be Radio Frequency Engineer?

Published

on

Radiofrequency (RF) technology is not the type of career that has a high wear rate. But if the job is as good as it sounds, why is it so difficult for companies to find RF engineers to fill their vacancies?

There are two main reasons. The first is due to the basic rule of supply and demand. The field of wireless communication has grown steadily in recent years, as have the areas of software and computer technology.

Because the demand for software developers has been so high, and the profession has a reputation for paying extremely high salaries, many engineering students have focused on this field.

How RF Works?

Radiofrequency (RF) is generated when an alternating current flows through a conductive substantial. Their frequency and length consider waves. The frequency is measured in Hertz(Hz) (or cycles per second) and the wavelength in meters (or centimeters).

Radio waves are electromagnetic waves and move at the speed of light in free space.

The equation that connects frequency and length is as follows: Speed ​​of light (c) = frequency x wavelength.

In the equation, you can see that the wavelength decreases as the RF frequency increases; this is how RF works.

Become a Radio Frequency Engineer

Radiofrequency engineers are specialists in the field of electrical engineering. They work with devices that send or receive radio waves, including wireless devices, radios, and cell phones. Training in general electronics, physics, and mathematics is required to design and improve wireless networks. Engineers must also have excellent communication skills, as they can expect to work as a team or with others outside their area of ​​expertise. These employees generally work in an office environment for a typical full-time week.

Skills Required

Although the role of the RF engineer is highly technical, general skills such as active listening and listening are critical to success in this area. RF engineers must also have the perfect mix of independent work and collaboration with others. Based on our analysis of vacancies for RF engineers, here are some general and advanced skills that employers expect from RF engineering candidates.

Job Description for Radio Frequency (RF) Engineer

RF engineers are in charge of conducting research that helps the success of communication sensors and surveillance radars, including research in the areas of bistatic, passive, and active multiple inputs, multiple outputs, monostaticdetectors, and speed cameras above the horizon.

RF engineers need to broaden their current knowledge of radio frequency sensor components, data acquisition, and analysis to improve the design, testing, and evaluation of radars. Their job is to take measurements to measure performance, efficiency, and relevance in the laboratory and to create systems that other engineers can use to test these areas in the laboratory. Executive engineers can directly supervise some of their work. Experienced engineers generally assist RF engineers in all aspects of data campaigns and acquisitions. Cleaning and office work may also require for each shift.

This situation generally requires at least five years of experience in the radiofrequency field. Some institutions require at least a bachelor’s degree in engineering, others a master’s degree. Some employers also need to know about analysis software such as Matlab, C, or VHDL.

RF Engineer Duties and Responsibilities

RF engineers specialize in the development, implementation, and maintenance of wireless communication systems. The following tasks and responsibilities illustrate what specific tasks look like

Optimize the performance of existing wireless networks

Think about how the wireless internet on our smartphones has changed from 1G to 4G LTE. These advances are the result of RF engineers who continually review the network’s KPIs and regularly maintain existing equipment.

Design RF patterns for new wireless networks

Another critical task for the RF engineer is to design RF diagrams for the construction of new wireless networks. For those working in telecommunications engineering, this can include surveying the land acquired to position communication towers optimally. This data then examined, and it used to create a personalized plan that makes the team’s vision a reality.

Make sure that the legal standards observed

Anyone operating in a regulated industry such as telecommunications must pass several government license tests. RF engineers use the information they received during this licensing process to ensure full compliance with FCC regulations.

Analyze the equipment and identify areas for improvement

Much of an RF engineer’s time is spent in the field, either installing new radios or maintaining existing equipment. It includes analyzing the functionality of the devices and recommending upgrades for decision-makers if necessary.

Communicate data with digital software

Understanding the KPIs of wireless networks in a way that decision-makers understand is an essential part of an RF engineer’s job. According to our research on job descriptions for HF engineers, this usually done using Excel worksheets.

Salary

The average salary for electronics engineers, which includes RF engineers, is $ 90,300. Agreeing to the BLS, those in the 90th percentile earn more than $ 152,000, while those in the 10th percentile make $ 63,400. The three states with the highest average wages for RF engineers are California at $ 111,500, Maryland, at $ 117,000, and Rhode Island at $ 118,600.

Primary Founder, James Billson, Shares Insight On How to Build Better Software with Application Modelling

Published

on

James Billson has seen it all in the tech world. He started his first pizza delivery business at a time when Wi-Fi didn’t exist and orders had to be delivered by fax.

This business transformed into a software development outfit, and with it, he witnessed the rise and fall of tech in the early 2000s.

He made his grand exit with a sale to international advertising behemoth BBDO. He now runs Primary,  the result of his years of development service experience. In this article, he shares a simple agile technique for building better software.

Agile methodologies are here to stay. They have received widespread acceptance in the sphere of software development. An agile approach helps teams to work together as well as with their stakeholders.

Agile practices help development organizations focus on their individual end-users and the way they interact with products.

Actions speak louder than words, and in software that is part of the problem. In the Agile Manifesto, having  ‘working software’ is prioritized over compiling comprehensive documentation that exhaustively defines the product before development. Coincidentally, this manifesto was written by coders, and the universal belief of a coder is, if there is a problem, code it. If we extend the definition of ‘working software’ to include an application model, opportunities to work faster and more efficiently arise.

Introducing Application Modelling

Much like in manufacturing, product modelling can be used as an alternative route to effective application design. Modelling is the process of creating a simulation that gives insight into how the real product will function at the end of the development process.

There are many merits to this approach. First, it re-creates the full size and expanse of the product, in a holistic full-dimensional way that allows due consideration of all its facets. This way, it helps the team to understand the features of the product better and translate it into a design that the users can also comprehend. Finally, it presents all the necessary information in a light and vivid format rather than the dull and impenetrable nature of typical requirements documentation…

With a well-developed application model, there is direct access to the full scope required for the development process. It removes the likelihood of overlooking future steps and pathways by revealing the features of the future product.

Involving the Whole Team with Modelling

Modelling creates a unique environment for synergy among the UX team, the developers, and the product owners. A product model is an agile system that allows real-time creation and modification. All parties can raise potential concerns and create a matching solution as work progresses. In comparison to a ‘straight-to-code’ process where decisions are usually made during development, application modelling greatly saves time and team resources.

Telling Stories with User Flows

James Billson founded Primary.app to give developers an easy way to conduct product modelling. However, beyond simply using a tool, there must also be a systematic approach.

Developing a product model should be very much like telling a story. A story has a single important ingredient that allows its teller to connect with audiences. This is the narrative. To find this narrative, the development team must create user flows. A user flow is a series of steps that outlines the journey of the product user through the life cycle of the application. The user is the hero, and over each step, we see what they do, how they do it, and why they do it.

The narrative of the flow is the backbone to which you attach the details and conditions that will inform the different aspects of the product work. Once you have that overreaching structure in place, you can manipulate and modify details, creating different user scenarios and comparing end results. All of this can be done without making any grave changes to the main body of the model.

User flow models have another advantage in helping product managers to avoid the pitfall of ‘happy pathways’.These happy paths are easy and fun when you are looking at an engaging prototype that has all the characteristics of your minimum desirable feature set. However, the building process will reveal all the other less exciting processes that are needed to support these main functions, leading to a development lag and a generally uncoordinated process. A user flow-based model will highlight these necessary support functions and help you stay on top of them from the very beginning.

Modelling is The New Documentation

Comprehensive documentation fell out of favour because it became seen as a blocker to creativity. Development teams want the freedom to identify opportunities that arise from seeing the product in operation.  As decisions are made in development, the document becomes increasingly redundant. The long descriptive passages and confusing diagrams did not lend themselves to easy updating. 

Application modelling completely redefines all of this. It is a light system that can be edited and modified in real-time. The entire team can make input based on the progress to date and see those ideas implemented in the following sprints. The result is a clean and compact model that mirrors the reality of the developed application. 

Conclusion

At Primary.app, James and his team have created a system that allows users to build large application models that are easily modifiable and constantly under development. Models can be changed any time, in response to key drivers that affect the app functionality in real life. It is as easy as changing sheets or doing the dishes before heading out.

Application modelling is the future of software development. User flow-based models of your app can be created with minimal resources, and then used to engage product team members for maximum and meaningful output. What you get is a comprehensive system that can be modified and iterated to synchronize with your desired result perfectly.

For SaaS Startups, Freemium Beats Free Trials

Published

on

Let’s get one point out of the way — your customers don’t really care very much about your aspirations for an IPO and shareholder liquidity. 

It’s an intuitive statement, but one that, in my experience as an investor, entrepreneurs often overlook when bringing a Software as a Service and other subscription-based startups to market. Just the other day, I was advising a pair of co-founders for a European startup who are expanding into the U.S. market. They were primarily focused on setting up their go-to market strategy to get to profitability within 18 months and then pay dividends to their investors. These founders made plans to build their business on a platform of paid subscribers and walled off any interest from a free user base that might last beyond a brief trial.

Theirs was a viable strategy, but not one suited to sustainable and strong growth. When founders for SaaS startups focus solely on free trial or paid only models that will allow them to repay their investors as quickly as possible, they curtail their company’s potential growth and can actually underrepresent the interests of their consumers. To succeed with a SaaS model, entrepreneurs should make a case for why customers should even bother to sign up or pay in the first place — and frequently the best way to accomplish that is to hook their users by demoing their services on a freemium model.

The Value of a Freemium Hook

When I spoke to the co-founders mentioned above, I pushed them hard to turn their free trial plans into a full-blown freemium model. It’s simple math; as marketing researcher Vineet Kumar put the matter in an article for the Harvard Business Review, “All other things being equal, you would do better to convert 5% of 2 million monthly visitors, for example, than to convert 50% of 100,000 visitors.” 

The research backing the freemium approach is compelling. Researchers have found that a free user is typically worth as much as 25% of what a fully-paid user is, and often brings significant value in the form of referrals. According to findings circulated by Kuman, these referrals plus a free-first approach can create a moderate conversion rate of between 2% and 5%. Those percentages may seem small, but when a SaaS startup’s cultivated user base counts in the tens of millions, they can bring in significant funds. 

That’s the value of a freemium model, and we see examples of its success everywhere — from our Hulu channels to Dropbox accounts and Linkedin profiles. 

However, such a model won’t find viral success immediately. Going freemium isn’t just about offering your product for free, it’s about how you do it, what you share, and what you withhold from free consumers. Why should people take the time to sign up for a free account? What makes your freemium model compelling, and how are you retaining or extending your Premium features to make your product the best in the pack? It’s not enough for SaaS startups to have a solid product and an accessible subscription model — they need to know which features to include in the free version to make it useful enough to demonstrate value, and which features they should offer to make signing up for a Premium subscription not just an attractive choice but an inevitable decision. 

Let’s consider Spotify as a case study. 

Spotify – A Case Study for Viral Freemium Success

Spotify was founded in Stockholm, Sweden, in 2006. Its founders, Daniel Ek and Martin Lorentzon, intended the platform to be the legal answer to the digital piracy that had plagued the music industry at the time. Their subscription streaming services proved to be precisely what consumers at the time needed, and Spotify came to revolutionize streaming music. It continues to dominate the industry today; according to the company’s 2019 Q1 earnings report, the platform now boasts 217 million monthly active users and 100 million (46%) paid subscribers.

It’s worth looking at the numbers, here. Spotify’s percentage paid rate stands out as a far cry from Kuman’s average 5% free-to-paid conversion rate. There are several reasons for this; first, Spotify found its niche and established itself as a foremost service provider early on in the streaming era, allowing it to gain a high number of subscribers before its competitors found their footing. Secondly, (and more relevantly for SaaS entrepreneurs) Spotify carefully designed its free packages to provide exactly what consumers needed — but not what they hadn’t yet realized that they wanted. 

Spotify’s free package offers users the wide music selection and on-demand features they want. However, it does so at lower sound quality than its premium offerings and only when the user has an internet connection. Spotify Free also interrupts users’ music streams with periodic advertisements. Premium, on the other hand, is entirely ad-free — and comes with higher sound quality and download capabilities to boot. Premium offers an answer to all the grating inconveniences that subscribers didn’t realize that they had until they tried Free and realized that they could have an ideal experience by upgrading. It removes the ads, the service interruptions, and low-quality offerings. For many subscribers, the convenience that those top-tier features provide is well worth the price of a premium subscription. 

The company has also found creative ways to hook users on their Premium offerings without first signing on to Free. In the last year, Spotify made a deal with Samsung to ensure that all consumers who purchase Samsung’s Galaxy S10 will receive a six-month free trial for Premium and the app pre-loaded on their phone. This deal will allow new customers to become accustomed to the conveniences of their Premium offerings and — when the trial comes to an end — either struggle with the now-unfamiliar inconveniences of the free package or sign on for a subscription. 

For early stage founders focused on liquidity, a freemium model may seem not adept enough at gathering paid subscriptions and reaching profitability quickly. In particular, as the market for capital formation tightens and the IPO window gets more challenging, controlling cash burn is important. In practice, however, freemium platforms aren’t centered on giving a service away for free but scaling quickly and efficiently. Your platform and message can reach a much larger base faster and if you have strong marketing and conversion strategies you can persuade a tangible portion of the subscriber base that your premium package is worth the upgrade. Successful freemium services achieve impressive, long-term gain by building on a bedrock of carefully-selected free services. This ultimately can make them more beneficial for investors and customers alike.  


When founders build SaaS businesses, they can’t focus solely on providing returns to their investors. Instead, they need to strike a balancing act that weighs the needs of consumers, investors, and the business itself. Freemium models can help founders accomplish this — but only if they can hone in on the why behind their business, find out what their customers will value the most (preferably before they have to ask for it), and craft premium and free packages that make upgrading a necessity, rather than a luxury.

5 Tips On How to Correctly Pitch to a Song to Spotify Playlist Curators

Published

on

By

In today’s era of streaming in the music industry, one of the biggest trends to surface has been marketing through Spotify playlists. While some independent curators charge for slots on their lists, others just curate their playlists for pure enjoyment. Although the process of pitching to curators and getting placed can often time seem like a drag, the results can be impeccable. The main problem I see with many managers and artists is that they shoot a thousand emails to a thousand different curators while missing some vital pieces of the pitching process.

Here are 5 tips to hopefully make the process a little less painful

Tip #1: Don’t send mass emails!

This is probably the worst mistake I have seen artists make. To avoid sending a thousand individual emails, some artists will simply just stack the same email with a number of different addresses. This is not a great way to do it at all. Curators can easily tell when you’ve sent a mass email and normally won’t even consider your track because of it.

Tip #2: Be specific!

One of the biggest mistakes I see artists and managers make while pitching to curators is being too general in the email. Something like “Hey, I came across your playlist on Spotify and thought my song would fit great” won’t cut it. One of the most helpful things you can do is be specific as to why your song would fit on the playlist. Maybe tell the curator how you came across his list, how you sound like an artist already on there, or something like that.

Tip #3: Give Compliments

This is a step almost 99 percent of artists and managers miss. I highly recommend giving the curator a compliment when submitting your song. This sets a nice tone and can easily win some brownie points. Don’t go overboard, just be kind.

Tip #4: Give Context!

I can’t stress the importance of giving context when pitching your song. Having a story behind your music brings it to life. It makes it real. By relaying your story to the curator you are opening a door for an emotional connection to the song. A lot of modern day decisions are based heavily on emotion.

Tip #5: Establish Relationship First

A key step to building your playlist volume up on Spotify is to become close with curators. If you can be friends with the curator take that opportunity. I’ve seen artists get on New Music Friday just from personally knowing a curator.

Final Thoughts

The process for building up a base of playlists on Spotify can be challenging, but the benefits are super important. When you stack up playlists you have a lot better shot of making Spotify’s own playlists and in-betweens like Discover Weekly. It’s all about the algorithm.
