Dual SIM Dual Active (DSDA)

Product Discussion Pepwave MAX
1

Hello Peplink team,

I wanted to find out if there are any routers that support Dual SIM Dual Active (DSDA) specifically something like the Pepwave HD2. In this case we dont need necessarily the redundant SIMs but rather we need both SIMs to be active.
Are there any products that support this feature?

Thanks,

Hi!

I’m only familiar with DSDA as a concept for making/receiving phone calls. I’m not sure exactly how that translates to use with a cellular gateway. Here are a couple of questions to help me understand…

  • What is the goal/use case?
  • Are you trying to bond the two connections?
  • Is the goal maximum throughput?
  • Are you trying to achieve maximum up time?

I suspect there is likely something that can achieve your needs in the Peplink portfolio. Have you looked into Speedfusion at all?

There are several Peplinks with more than one cellular connection. All of those support two or more active cellular connections, depending on the amount of modems in it.

Many models have double slots per modem, only one slot per modem can be active at a time. This is not unique to Peplink but just how it’s physically connected internally to the modems.

Hi all and thanks for the feedback.

for DSDA, we’ve seen modems that do support this for both voice and data at the module level but not many at the product level.
There is the use case that yes you can use multiple modems at the problem but this does typically come at a higher cost point and is really overkill for the solution.

Speed fusion is an option yes but fundamentally it’s only as good as the number of active connections. having two SIMs which are metered is good but in the event of robustness I’m struggling to see how this actually helps maintain the link. As far as I can tell the link is only as good as the number of active modems. is that correct?

thanks,

I’d like to see DSDA implemented ,not for two always one data connections, but for both carriers to be connected at the same time.
It could allow sms control on both numbers and then have the pepwave switch to either the one with the better signal or check every definded interval which has the better speed when it’s idle. That makes a lot of sense to me.
