Bad explanation of frequency reuse

This article omits explaining that the entire reason cellular technology was developed was frequency reuse. The Infrastructure section says at the top "Each cell uses a different set of frequencies from neighboring cells" and doesn't make clear that nonadjacent cells reuse frequencies, only mentioning this at the end. It doesn't mention the overcrowded radio spectrum and that there is not enough bandwidth in the entire mobile band to give each phone in a medium sized town its own frequencies, much less an entire country. In the mobile phone systems before the advent of cellular, callers often had to wait until one of the limited number of channels was free to make a call. The amateurish example at the bottom "one uses frequency 1–500, next door cell uses frequency 501–1,000" doesn't explain how many channels an actual cell phone system is assigned. The text doesn't make clear that the cell tower transmitters have low enough power that the radio waves don't interfere with nearby cells using the same frequencies. --Chetvorno^TALK 05:56, 25 January 2023 (UTC)

The first cellphone

The first cellphone information is incorrect and says that it was introduced in 1973 and that's wrong. I have an article showing Mansfield Telephone Co. had a prototype in 1963, it would not allow me to edit it. ~*Brandi*Marie*~ 03:55, 16 April 2023 (UTC) — Preceding unsigned comment added by Brandimarie1985 (talk • contribs)

"Mobile phone (or cellphone)"

As confirmed in the article, these are not synonyms. Grassynoel (talk) 11:20, 12 February 2024 (UTC)

Are there still a lot of mobile phones that aren't cellular? --Wtshymanski (talk) 17:36, 16 February 2024 (UTC)

More information needed

" The growth in popularity has been rapid in some places, for example, in the UK, the total number of mobile phones overtook the number of houses in 1999. Today, mobile phones are globally ubiquitous, and in almost half the world's countries, over 90% of the population owns at least one. " - It would be nice to have more detail on this. Also, is >90% even really correct? Or is it >90% of those people over age X ? Considering that 5.6% of the US population is under five (https://www.census.gov/quickfacts/fact/table/US/RHI125222), I find it improbable that the >90% figure is correct.

Clarification on Recent Edits to the Mobile Phone Wikipedia Page

Hi @MrOllie,

I hope you’re doing well! I noticed that you reverted my edits to the Mobile Phone Wikipedia page, and I wanted to touch base with you. I’m a bit curious about how my edits might have contradicted the existing content. I was excited to add some details about a mobile phone created by Millicom, and E.F. Johnson & Co. I want to make sure my contributions are helpful and accurate. Thanks so much for your time! I really appreciate your feedback and look forward to hearing from you.

Best,
