Aviat Vendor Agnostic Multi-Band

[@tituskipkorir9540]

I guess it's a good product but it's also good to mention Capacity Limitations on the 23Ghz which gives a capacity backup of around 570Mbps. Assuming We can push proper traffic to a tune of 800Mbps on the main mmwCarrier, we will definitely suffer service degradation when there is a fail over to the backup link. Good to have a disclaimer on that

other vendor use one dual band antenna to combine mmW and mW traffic as L1 radio aggregation

This 23GHZ what is the distance coverage

New technology? Game changer? Definitely not. 1) Radio aggregation has been around for many years. Most users allow the switch to load balance the two links running in parallel. Sure, you can use a radio to aggregate the traffic, buy why, unless you don't own a capable switch? 2) E-band - 10 Gbps is great for bandwidth, but not for distance. How many E-band radios are used reliably on paths longer than 1 mile? Depending on where you're located, 1/2 mile may be the max range for E-band frequencies. 3) We all get it - the 23 GHz link is basically a backup when the E-band radio fails. Next time, tell us the path length, ITU rain rate region, and the path availability of the E-band and 23 GHz radios. I'd like to see more data and less opinion.

I agree with you.

Tony C, thanks for your comment. We can try to address your questions….1) It is true that aggregating radio channels has been done for some time at L1. The improvement with MB-VA is we are aggregating an E-Band with a Microwave channel, which have very different latencies. This can be a real challenge for many ‘standard’ aggregation algorithms. We also do this with very high efficiency of up to 98%; 2) You are right that E-band is very distance challenged in some climates. The range of an E-band link can be anything from less than 1 mile to more than 3 miles (in a dry climate) with at least 99.99% availability, but we have deployed E-Band successfully over much longer distances with great results. But this is why Multi-Band is so useful - you can stretch the links out much further and get at least 99% availability on the vast majority of your traffic, while maintaining the most important traffic on the Microwave channel at 99.995% or better.; and 3) the 23 GHz link is not configured as a ‘backup link’, where traffic is 'switched' when the E-band link fails to the Microwave link (which is running in standby mode and not normally carrying traffic), with a resulting traffic hit. In contrast, Aviat's L1 Link Aggregation algorithm utilizes and shares the capacity of both links at all times, so if you only can use a 250 MHz channel on the E-Band link you can take advantage of the all microwave link capacity as well. When the E-Band link fails the high priority traffic is maintained on the microwave link with no switching, and no traffic hit at all. Doing this with your own radios is straightforward, but not when you want to upgrade an existing 3rd party microwave link with an E-Band overlay. This is what Aviat's MB-VA does so well. You can also use an external Ethernet switch to do this if you want, but not at L1, so the efficiency and capacity utilization will not be anywhere near as good.
