Cell phones, one the other hand, take great pains to ensure only the intended recipient has access to the information being broadast. Amateur radios can transmit at higher power, up to 1500 W in the US, while cell phones are usually less than 5 watts to limit interference. This also means cell phone signals don’t travel as far and have to be handed off from tower to tower. Amateur radio is usually going to be point to point, although there are various repeaters and gateways available. Finally, many amateur frequencies can skip off the atmosphere and reach hundreds, even thousands of miles. Cell phone frequencies specifically avoid this to limit interference.Besides that, they have lots in common. They both transmit using radio waves, they both can be analog or digital, and both can be used to transmit voice or data.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
