Low or modest data requirement in Failover to 4G
There is a low-cost rental multi-network SIM with no attached data allowance and data is charged per megabyte when the SIM is actively passing data. This is a good solution where the data requirement when in back-up/failover to 4G, is modest or controllable.
Medium to high Data use
Choose a data allowance from our price list that is a reasonable estimate of the likely data usage when in failover mode and if required add a bolt-on of additional data if the usage is significantly above the data allowance in any given month. If it is only just over the data allowance, it can be more cost effective to just pay for the overuse as our rates are very reasonable in comparison to many other suppliers.
Where the SIMs are on the same network and data allowance we can aggregate the individual SIM data allowances into a shared pool of data which is available to any single site that needed to failover to 4G. With multi-network SIMs this can be done regardless of which operator each site uses. So, a simple example would be if the estimate is 50GB to support a site whose fixed line had failed and there were 10 sites, we can supply 5GB SIMs to each site to create the shared data pool required to support the effected site.
Very high data use
If fixed IP is required, we would deploy an SD-WAN device with a public fixed IP and provide a 4G or 5G router with one or two “unlimited” dynamic IP SIMs from Vodafone and/or O2.
The SD-WAN software defined networking device has been designed to avoid the higher costs of high data capacity fixed IP data SIM contracts. This device has four main functions; 1) It hosts the public fixed IP(s) 2) It handles port forwarding to any attached devices 3) It provides QoS controls to prioritise any interactive traffic such as VoIP or remote desktop 4) It provides protection from DDoS attacks. This solution is designed to be plugged into existing LAN infrastructure and can also be used in conjunction with 5G routers with dynamic IP SIMs.
Where there is a need for high data volumes, speed is also a consideration and so where 5G coverage exists, it would be a good choice. Otherwise 4G LTE has been developed beyond the original LTE CAT4 standard where the maximum theoretical download speed is 150mbps and an upload of 50mbps. There are now CAT6 routers with double the maximum download speed of CAT4, CAT12 routers with 600mbps down and 100mbps up and the latest is the CAT20 router with a maximum of 2gbps down and 300mbps upload. The cost of the routers goes up slightly with the faster routers, however, the costs of not having a useable internet connection in today’s world can huge.
