NetAmerica Alliance Model: Uniport – a.k.a. Ericsson MBR L21. This picture is of an L21 in Pompano Beach, Florida during testing without an external antenna.
In the next few days we will be installing and testing an Ericsson L21 on a yacht in the Miami, Florida area. We will be connecting an external antenna – and activating the unit on a 4G LTE connection (likely AT&T). Actually with the picture above we have tested one NOT on a yacht but in a house.
Often nobody wants to be the first one to try a product, and yachts are no different. Everyone wants proven technology and systems. Well these units were designed to be used in homes and businesses (and mobile platforms? ie the name Mobile Broadband Router) with either the built-in cellular antennas or with an external antenna. (With the picture above: 04/18/2013 – an L21 has been tested on AT&T LTE 4G Network … 4G Sim Card. We had to enter “broadband” as the APN in order to get it to work.)
They have some very neat functionality built-in to them. Not many on yachts probably know what an “Asterisk Software PBX” is … but I do. I have experimented with the software. But basically the Ericsson L21 came with a limited miniature installation of Asterisk PBX installed and configurable as part of the Very Nice Web GUI (Management Interface.) This PBX allows 1 RJ-11 actual hard wired Telephone extension … This could even be used as a connection (as was done before with Ericsson W25 and W35) to a boats actual hardware PBX system. But what’s even cooler about this is that it allows 4 VOIP Phones. That could be hardware SIP Phones or Software SIP instances. In other words you could pick 4 important locations (or persons) that get a SIP extension to the “Mini-PBX” that can make and receive VOIP telephone calls. A SIP VOIP provider is required – and that can be easily configured in the system.
* Anyway I will try and post the results of the installation testing after it’s done, on here.
