Deciding to get a new piece of equipment can be an exciting time, especially if it's been 7 years since you upgraded your Hotspot device!
I will be more than happy to provide you with some information on the benefits of upgrading to a newer device. There are three main differences between these two devices that I would like to highlight for you; battery life, speeds, and Wi-Fi technology.
The battery life in your current unit is only 2000 mAh which will give you about up to 6 hours of use if the battery is healthy. The Novatel has a 4400 mAh battery and is a far more efficient unit with a battery life of up to 24 hours and it has Quick Charge with USB Type-C.
The AC763S can only achieve maximum download speeds of up to 100 Mbps. The Novatel is capable of speeds of up to 337.7 Mbps using LTE Cat 9 which is over 3 times faster.
The AC763S only supports 2.4 G Wi-Fi and up to 10 devices can connect at a time. The Novatel supports 2.4 G and 5 G Wi-Fi and up to 15 users can connect at the same time. 5 G Wi-Fi is significantly faster than the 2.4 G and it less susceptible to interference from other devices using the 2.4 G bands.
The Novatel is definitely a much more advanced device. I personally haven't used either of these devices but if there are users in the Community who have experience with them feel free to chime in! =)
I'm not convinced that this is going to make any difference, given our location -- distant, with marginal Rogers service -- but I bought the new hotspot anyway, at Rogers in Barrie. We'll be back in Canada in a couple of months, and then we'll see if there's any noticeable improvement.
