4G WAN Overview

What do you need to set it up?

A 4G WAN solution is made up of four main components. Once these have been set up and configured, your connection will be available immediately.

  • Site routers
  • 4G SIMs from multiple carriers
  • An optional central hub if you are bonding (which is sited in your data centre or hosted on your behalf)
  • A management service

Your hub will be set up in your data centre (or your MSP may offer to host it in theirs).  The site routers need to be sent to site along with the SIMs, ready for set-up, configuration and importantly, tuning (which is best done by an engineer working with a Network Operations Centre).

A central hub

The central hub is what bonds the traffic from the SIMs at your sites. It can support multiple sites, and can be installed at multiple data centres if required, or hosted on your behalf.

A 4G router

Your 4G router is delivered to site together with your SIMs. The router provides the secure connection back to your central hub. We’ll highlight things to look out for in a router, later in this document.  Two of the leading providers of 4G routers that we like are Peplink and Viprinet.

4G SIMs

Multiple 4G SIMs are bonded to provide you with a single, high speed connection. For additional resilience and 100% coverage, you can bond SIMs from multiple mobile networks. However, you should avoid mixing 3G and 4G SIMs in the bond as the maximum performance of the network will be determined by the slowest connection – which will be the much slower 3G network in this situation.

Monitoring

This means that your department, and your chosen supplier, can monitor the performance of your solution 24/7 – giving you complete confidence and peace of mind.

All in one box

Since 4G WAN is so often required quickly, experienced suppliers will hold pre-configured routers, with SIMs and aerials ready to go.  They’ll have them boxed in appropriate containers because of the environments they’re commonly going to. They’ll usually also have a mix of aerial types to cope with the specific location that they’ll be going to.  The best providers will be able to have an engineer bring this to site and set it up for you within a couple of working days.
