Speeds and Signals
Why am I getting slower speed with this product than
with the mobile phone?
The latest mobile phones, will often have a higher Cat
standard than that of a 4G router, so the speeds attainable are
higher.
Creating a hotspot, will cause your device to be unusable as a
phone during this period, as answering a call will interrupt the
hotspot and will cause the battery to discharge quite rapidly.
How can I improve the 4G signal by finding a better
placement of the product?
Yes, 4G/5G signals are often strongest outside, so positioning
your device near a window is optimal.
Once the device is setup, we recommend running a few
speedtests to find the best position within your home (www.
speedtest.net)
Does geographical location have an impact on the speed
of the 4G connection?
Yes, before purchasing a 4G router/hotspot, please check the
availability of 4G/5G in your local area, to better ascertain the
signal strength available.
