While China has been a leader in 5G development and has already woven into telecom systems in the rural U.S., Washington is voicing concerns over the security of the networking equipment.China says its simply a ploy to hamstring Chinese companies, while U.S. and European companies catch up in the 5G market.Wherever the truth lies, theres plenty of opportunity with 5G stocks, since Chinas privately held Huawei isnt likely to run away with all the global 5G business. 7 Travel Stocks to Buy Banking On Pent-Up Demand My selection of the best 5G stocks includes the following seven stocks: Telefon AB LM Ericsson NASDAQ:ERIC Samsung Electronics OTCMKTS:SSNLF Digital Realty Trust NYSE:DLR Corporate Office Properties NYSE:OFC BCE Inc NYSE:BCE ATT NYSE:T Verizon NYSE:VZFor an in-depth look at the biggest winners in the 5G revolution, InvestorPlace advisor Matt McCalls 5G Highway Super Portfolio considers many facets to the movement that investors are overlooking.

But now, Ericsson is again a leading 5G equipment provider, supporting 55 live 5G networks, in 27 countries, including China.ERIC stock is finally getting the attention it deserves, which means its still one of the and its up 35 in the past 12 months, near its 52-week high. Theres plenty more growth to come. Samsung Electronics SSNLFSource: JPstock Shutterstock.com Theres little doubt that you havent yet heard of this South Korea-based electronics giant.But its not in this list because all of its mobile phones will be 5G-ready by the end of the year. Or that 90 of its phones will be Internet of Things IoT enabled.In fact, 5G is about much more than just faster mobile phone connectivity. It will enable the next steps in multiple technological revolutions, which is a large part of why identifying the best 5G stocks to buy is so important for todays investors.The biggest benefit of Samsung from a 5G perspective is its 5G chipsets. It is a massive chip maker.According to B2B networker BizVibe, Samsung is the largest semiconductor chipmaker by revenue in the world by a large margin. It has 44.8 of the global chip market, with Intel NASDAQ:INTC far behind in second place, with 15.5.The fact is, Samsung makes chips for all its own devices as well as a lot of others. Its consumer electronics is its most obvious business but its dominance in chips is significant.And if its phones are all 5G enabled, it is also selling those chips to other phone makers.Whats more, it also sells the networking equipment that makes 5G run. 10 Small-Cap Stocks Ready to Become Large Caps SSNLF stock is a little more difficult to buy because it is only listed in South Korea, but its ADR is available and worth the trouble. SSNLF is up 33 in the past year and will be a strong player for many years to come. Digital Realty Trust DLRSource: Shutterstock This real estate investment trust REIT is one of the leaders in hosting secure, reliable and state of the art data center properties for cloud computing, artificial intelligence, financial services, healthcare and networking.In that laundry list you can include 5G networking equipment.DLR estimates that there will be 75 billion mobile phones in use by 2025. And by that point they will all be using 5G technology, which is 100x faster than current 4G technology. Thats the difference between downloading a movie in 7 minutes with 4G, versus 10 seconds with 5G.Thats a game changer. And DLR will be the company that carriers and networkers turn to for data centers that are ready for the coming 5G boom.With 280 data centers in 22 countries on 6 continents, Digital Realty Trust will be a major player.DLR stock is up 30 in the past year and still delivers a respectable 2.8 dividend. Corporate Office Properties OFCSource: Shutterstock This is another REIT that is in the office property and data center sectors, but it is less than a tenth of the market cap of DLR.However, it has a very specific niche that makes it a key 5G stock to consider. Specifically, it operates around the Washington, D.C. area to government agencies, defense and intelligence agencies and contractors.Its top 3 tenants include the General Services Administration the U.S. governments real estate department with 34 of total 2019 revenue, Amazon NASDAQ:AMZN at 7.9 and General Dynamics NYSE:GD at 4.9.That is the ideal tenant in todays market. Whats more, working with the defense and intelligence communities means OFC can build out secure data centers to exactly the specifications that their clients need and know that theyll get pricing to make it profitable.However, as McCall reminds us, 5G road builders like OFC, DLR and others on this list are just the tip of the iceberg. They will be among the power players in the 5G revolution, but the key players he identifies with his research team are the ones that will drive on that road for years to come with their breakthrough technologies. The 7 Best 5G Stocks to Buy Now OFC stock is off 5 in the past year, but it delivers a 4 dividend. And many analysts are beginning to upgrade the stock in recent weeks. BCE BCESource: madamF Shutterstock.com Investors often look to telecom stocks like BCE for income. After all, telecoms often pay some of the largest dividends. But thats not the only way to find income. My book, Income for Life details more than 60 different revenue streams anyone can collect.While you sift over all of those unique ways to make money, Id also like to change the way you view BCE stock. Instead of looking at it as just a telecom stock, imagine its role in our upcoming 5G future.It has been a dominant carrier for almost 40 years, its a household name and it doesnt have a ton of competition.BCE is the Baby Bell of Canada. For those of you too young to remember, ATT aka, Ma Bell dominated the entire North American phone market until it was broken up into the Baby Bells in 1984 through an anti-trust lawsuit.Bell Canada Enterprises was formed in 1983 and remains one of Canadas largest companies and a dominant player in the nations telecommunications industry.And now its set to be one of the key road builders in 5G networks. In June, it launched the largest 5G network in Canada. Its using equipment from Nokia NYSE:NOK, so there wont be any trade issues with the U.S. or Europe regarding its 5G infrastructure in the future.BCE stock is off a bit over 7 in the past year, but it has a 5.7 dividend and will be a reliable and important telecom stock in the long term. ATT TSource: Jonathan WeissShutterstock Ma Bell was such a powerful force before its breakup that there was a movie in the early 1970s where it was simply called tongue in cheek of course The Phone Company.After the breakup, ATT lost its local markets, but kept its international markets and national U.S. market. No one was thinking about mobile phones back then, so they werent in the deal.The Baby Bells had a good run until the mobile wave hit. And then ATT dove back in and became a dominant player almost immediately.Today it has a market cap of 212 billion and is one of the bluest blue chips around. But it also has a lot more competition. Thats why it has diversified into content and streaming services.All this has been new to this traditional telecom and it has proven to be a bumpy ride. But this is a long-term play. 7 Travel Stocks to Buy Banking On Pent-Up Demand T stock is off 13 in the past 12 months, but it has a secure dividend of nearly 7. There are some near-term concerns about consumer belt-tightening and defaults, but it will endure. Verizon VZSource: Ken Wolter Shutterstock.com This company was one of the Baby Bells that flourished after the breakup. Bell Atlantic, as it was called operated in a very important corridor -- Virginia to New Jersey.That meant it had all the U.S. government, all the New York businesses and offices in New Jersey, as well as Philadelphia and other key Mid-Atlantic business and population hubs.When the mobile telecom revolution hit, it went on an acquisition spree buying up mobile territories where weaker Baby Bells couldnt afford to launch mobile divisions.Soon it was neck and neck with ATT and optimizing its fiber optic network to deliver content which directly competed with cable providers.It now carries a 240 billion market cap, yet trades at a price-to-earnings ratio of 12x. And its the No. 1 mobile carrier in the U.S.
