BaoFeng DMR! BaoFeng DM-5R Dual Band DMR Digital Radio.....and it starts!

These sons of bitches getting licenses these days (WITH CERTAIN EXCEPTIONS) think their IT certifications make them experts in the radio field. *sigh*. These are appliance operators.

That's why the average enterprise WLAN is terrible.

Does it have Telnet? Does it have SNMP? Is it a managed scalable solution as a service SAAS? What kind of an endpoint doesn't have SNMP, SSH, or Telnet? Where is the single pain of glass hosted on the private cloud?

They don't even know IT, they buy their wireless APs based on who their switching and routing vendor is, not who has the best RF and antenna design, thermal management, cpu, ram, and software/firmware.

Gotta love those Aironets frequently installed with 2 feet of tiny coax to panel antennas with massive feedline loss at 2.4/5GHz.

When you have decent internal RF design with implicit beamforming on 2.4GHz (where you only have 3 non-overlapping channels) which was optional in 802.11N 2009 (and only Belair, Ruckus, and few others bothered to implement), you don't need so many crappy APs and panel antennas with lossy feedlines to mitigate interference and do efficient channel reuse.

With 5GHz, you can get away with junkier access points closer together since there is more spectrum, but 802.11AC decent throughput is only realized with high quality RF design. Otherwise its just like flaky inconsistent 802.11N 5GHz HT40 on Steroids.

On most APs out there, change a phone or tablet from vertical polarization to horizontal (laying on table) and you loose 6db since the design doesn't account for it. Not to mention all of the unnecessary multipath and reflection on onmi antennas or poorly designed beamforming elements.

Have you been laughing at all the consumer shit just plastered with antennas these days (I mean as saw a router AP with at least 9 antennas on it)? Triple chain and up are where I start deeming excessive for PMP use (one vertical, the other horizontal is how I like it). Granted majority of my 802.11 experience is solely based on wide area WLANS (with backhauls spanning miles) in more of a cellular sectorized type setup and not necessarily an enterprise setup. I don't claim to know jack shit about routing…just what I've picked up working with microwave radios over the years.

What is the difference between a Tier 1 and Tier 2 DMR radio? Wasn't able to find any info about the difference.

Tier 1 is dPMR in Europe, an unlicensed FRS type digital service. The radios are simplex and low power mode only.

Has Anyone purchased one yet? And how is the tier 2 upgrade going to work? Will it be a flash? Or a fix? I didn't think these radios were sophisticated enough for flashing.

The tier 2 upgrade will not work. Read this. What a POS!!! GARY
haha, just got this from Radioddity in regards to the DM-5R.. I knew it!

Dear Customer,

We have an update for you on the status of the BaoFeng DM-5R.
Your DM-5R is ready to be shipped. We are confident you will enjoy the crisp, clear sound of the DM-5R. The DM-5R comes out of the box supporting only MOTOTRBO Tier I.

Thanks to the help of our Radioddity Review Team, we have found a bug in the software that makes updating the radio to Tier II inherently risky. If upgraded incorrectly, the user faces the possibility of disabling the radio, which would then need to be sent back to the manufacturer for repair. Radioddity does not suggest that you upgrade your DM-5R to Tier II manually. Manual upgrading should be done only by professionals.

We are working to fix this. We will re-release the DM-5R in one month’s time with a system update. This re-release will have Tier II standard.
Here are your options:

- Maintain your order status, receive the DM-5R with the current software in the next 5-10 days.
- Transfer your order to a DM-5R with upgraded software, for no additional price. Receive your radio October 20-30th.
- Cancel your order, receive a full refund.

We are working to provide detailed documentation to assist in the Tier II upgrading process, to support those who wish to upgrade their DM-5R.

Please respond to this email and let us know which option you would like to take going forward.

Sincerely,
Radioddity

Well at least they will give the money back
