Establishing IP Based Repeater Network

[guzinmf_2017]

Good Afternoon,

My company is currently attempting to establish a private DMR IP connected conventional network and was just wondering if there were any suggestions someone might have for hardware and vendors who provide these systems and services. I am open to any manufacturer except Hytera or any of their subsidiaries. I am under the impression that Mototrbo is likely my best best, but if there are other vendors and manufacturer barring the ones I already mentioned that someone might suggest that would ideal. Thanks for any insight you can provide.

Tait offers networked DMR hardware. I don't know much about it but I know it's out there.

Mototrbo would be a good contender. Recommend Ip Site Connect or Linked Capacity Plus (depends on system needs). TT

MotoTrbo IP site connect looks like a great solution, one I have recommended. I have heard however, that Motorola has since made it a bit less friendly to implement. Aside from the legal issues regarding Motorola patent infringement, Hytera has a terrific line up of equipment and DMR capabilities that surpass Motorola's offerings. They, Hytera are unfairly being dragged into the federal spotlight due to being a Chinese firm. I suspect Motorola has applied pressure to DOJ to their own advantage. I would not discount Hytera as a supplier.

Difficult to be sure how large your network will be from the description, but I would definitely look at Kenwood as well as Tait. ICOM has some linkable products as well, but does not offer DMR.

Just a thought does your company have a FCC license for the frequency used at each site?
Most are only licensed for a base site and radius of that site.
Anything CHINA and IP is a security risk per US even the CELLPHONE SYSTEMS that were China owned have been shut down in the US.

Find a local dealer / shop to work with -- They are going to know a lot about your local area from FCC Licensed Frequencies (used & open) to Low Voltage codes for site installations. One two hour sit down with a good dealer / shop will save you tens if not hundreds of hours.

We will be getting licenses to transmit.

As Firebuff stated, don't place a high value on the brand, find a local dealer/partner that you are comfortable using. Having worked for Motorola and now working at a large dealership, I am a bit partial to the brand and how it works. But, the people who design, I stall, and maintain the equipment will have a greater impact on your satisfaction than a specific brand. TT

Also, for these business repeater licenses, once my company owns the licenses for the frequencies, there's no need for the individual users to be licensed correct? They would be covered for use on my repeaters by our licenses?

Most FCC "IG" business licenses are site specific (need tower location, height etc) with Frequency Coordinator recommending frequency to FCC and a specific radius for portables and mobiles around the tower location. So it is best to have a plan and proposed sites and obtain the FCC license before purchasing the correct equipment. The license part takes patience, but is a crucial piece of an overall successful plan for the communications project to deliver commercial value for the business. The repeaters and radios would be able to operate for the company according to the parameters of the FCC license without additional individual user licensing.

Hytera got dragged into this by Motorola for having the audacity to compete with them. Oh the intellectual property thing? Motorola sent engineers to Japan back in the early days of cellular to eavesdrop on the Japan cellular telephone network switch.

What I was trying to say was what was said in post #11
If each repeater site has to have its own License
You have to License each Repeater and its area of operation.

I've installed Trbo and Hytera, both worked well. Hytera does analog, it's been about 7 years since I worked at Bearcom so I don't recall if Trbo had that.

We have implemented a trbo system using all used moto geat and it works well. We started with a multi site IP Site connect and eventually went to linked capacity plus.

Lately we have been working with Icom "IDAS" which is NXDN type D. I like it better than trbo. both have plusses and minuses. Both are not hard to build.

If you go Motorola Trbo, here is some "light reading" which may shed some light on Trbo based systems. More what your installer maintainers would need to know though. https://www.lightspeedcommunication...s/2015/12/MOTO-TRBO-System_Planner-111715.pdf

I used to work for the JVC/Kenwood Group (Zetron) and some NXDN networks....Icom was across the street, so I did some IDAS, as others have mentioned, it comes down to the install and attention to detail, not necessarily the brand. Although, you do get pulled into a specific brand ecosystem at some point.
