The following Q&A were a selection of the remaining questions we ran out of time to answer at our Replacing Leased Lines with Smart Radios webinar session.
Q. What FCC part certifications do you support?
A. For radio performance, we support the following:
400MHz – FCC 47CFR part 90
700MHz – FCC 47CFR part 27
900MHz – FCC 47CFR part 101
Q. Do you have a VHF solution?
A. Mimomax does have a VHF version of our Tornado radio, however, we are currently working on an enhancement to this product – after which it will need to go through the compliance process. For this reason, the VHF product is not listed as available currently on our website. If you have a VHF opportunity you would like to discuss, please reach out to us so we can look at how our timelines may fit with your needs.
Q. What is Mimomax’s Yagi antenna gain and beamwidth?
A. We offer a range of antennas which can be found here. In 700MHz we offer a 12dBi and a 15dBi Yagi and can provide a 400MHz yagi also.
Our 700MHz 12dBi Yagi has an E-Plane 3 dB Beamwidth of 42 degrees and an H-Plane 3 dB Beamwidth of 49 degrees.
Our 15dBi Yagi has an E-Plane 3dB Beamwidth of 30 degrees and an H-Plane 3 dB Beamwidth of 35 degrees.
Q. Is the Over the Air protocol proprietary or a standard like IEEE 802.16?
A. Mimomax’s OTA protocol is proprietary.
Q. Is the NMS SNMP compliant for use with a Manager of Manager?
A. Mimomax works with a variety of third party NMS providers. You would need to check compliance with a Manager of Manager with each NMS vendor.
Q. Is there an RF Coverage tool you offer to assist with moves/additions or changes?
A. Mimomax offers a free preliminary RF Coverage design service and can provide this service, for a fee, for future changes/additions to one of our networks or links.
Q. What is the Effective Radiated Power of the 700MHz radio?
A. This will depend on the gain of the antenna you use. As an example, if you take the Tornado’s 24dBm transmit power and use a 10dB gain antenna, your ERP will be 34 dBm.
Q. Regarding latency, if you could do under 4 milliseconds per hop, how many hops on a 25 mile path?
A. This depends entirely on the path loss on the link in question and would take into account antenna height, clutter and terrain. We have achieved links of up to 60 miles with a single hop in the right environment (i.e. clear line of sight, from hilltop to hilltop) so the number of hops required for any link is contingent upon environmental factors.
Q. Does the link stay up if something in either the horizontal or vertical part of the radio, coax or antenna element fails?
A. Unfortunately, with our current Tornado radio the answer would be “no”. This may be a feature for one of our future product developments – however, it would come at a cost to the data throughput and latency rates. If low latency and high throughput is critical for the application you are running, a more resilient approach would be to use our 1+1 solution which would ensure hot-swappable redundancy in the event of failure in the primary link. We also have a redundant antenna solution available.
