Talk:Personal radio service

Purpose?

What is the purpose of this page as much of its content is simply copied from Family Radio Service? —danhash (talk) 19:35, 9 March 2012 (UTC)

Well, ultimately, there will be a summary of this page at the FRS page and all the non-FRS radio services will be described here. Ultimately this could be a list of all the world's personal radio services with blue links to detailed articles on each one...that might not happen in my lifetime, so this article is a step in that direction. It seems desirable for an article to be about its topic, and if we've got so much material on a related but different topic, it should be another article. --Wtshymanski (talk) 22:46, 9 March 2012 (UTC)

It is also largely a duplicate of PMR446 and other material. This article should be deleted. DieSwartzPunkt (talk) 15:18, 6 June 2012 (UTC)

removed prod

I've removed a prod from this. It was on the basis that it's a duplication of other (unspecified) articles. I presume that the articles implied are Family Radio Service and PMR446. One difference between these articles is that Personal radio service (or Personal mobile radio, call it whatever you like) would be an international article, whilst FRS & PMR446 are national systems that would likely be unknown to someone from outside their regulatory sphere.

Prune the unnecessary duplication by all means, but there is clearly value in an article with the scope of "Worldwide systems for personal mobile radio". This seems to be the current closest we have to that. Andy Dingley (talk) 15:08, 7 June 2012 (UTC)

What an article can become

It's come a long way in 6 years. I'd like to see more references. Dates of initiation of services would be useful as well. It looks like UHF personal radio services really started to flourish in the late '90s, I wonder if anyone has written about why this was so - all that cell phone R&D making cheap RF power transistors widely available? --Wtshymanski (talk) 16:06, 16 April 2019 (UTC)

Japan

I tried to find more information about 900MHz personal radios in Japan, but couldn't find anything to support their availability. Every source I found indicates that the 903MHz band is assigned to cellular phones. --Bigpeteb (talk) 23:32, 27 August 2019 (UTC)

This application was assigned 903-905MHz until the end of November 2015. Channel control is MCA and Up to 5W operation is possible with FM. The frequency assignment was handed over to the mobile phone. Currently, only licensed sets are allowed to operate.

VHF in Japan

I've tried to verify the VHF range, but can't find any info about it. SLPR covers use of 142 MHz for animal tracking, but the usage (5 channels from 142.94-142.98 MHz, 10 kHz spacing, 1 watt) doesn't quite match what's described here (18 channels from 142.934375–142.984375 MHz and 146.934375–146.984375 MHz, 6.25 kHz spacing, 0.5 watts). The closest thing I see is that Digital Simple Radio (デジタル簡易無線, dejitaru kan'i musenkyoku) covers 28 channels at 154.44375-154.61250 MHz, 6.25 kHz spacing, 5 watts, for digital voice and data. Is this what was meant, or have the standard perhaps changed since this text was written? --Bigpeteb (talk) 19:31, 8 September 2020 (UTC)

"デジタル簡易無線" is 5W (1W for airspace use) and uses 154MHz, 467MHz and 351MHz. 154MHz and 467MHz are for business use only and cannot be used for leisure.

In 2023, the number of 351MHz デジタル簡易無線 channels will be increased and used 351.03125 to 351.1 MHz ,351.2 to 351.63125 MHz.

The "デジタル小電力コミュニティ無線"(Digital low-power community radio) is 0.5 W and uses 142.934375 to 142.984375 MHz,146.934375 to 146.984375 MHz. Available for both leisure and business, it is mandated to transmit GPS information. In the past, this frequency could only be used for animal tracking, but in 2018 the regulations were relaxed to allow use as walkie-tokie it.

Confusingly: "パーソナル無線"(pāsonaru musen, Personal radio) are analog(FM) radios using 900 MHz. The personal radio system is ended in 2021, and its spectrum is currently allocated to cellular phones. 61.197.110.136 (talk) 03:56, 19 April 2024 (UTC)
