Resilient Network Set Up via TTCL Internet

Hey guys,

So I recently got connected via TTCL fiber. I used their Triple Hub Extra fiber deal that costs 100,000 per month

It has the following offers (all included in the price above):

• 150 Mbps unlimited internet via fiber
• 30GB per month via mobile data (4G/5G)
• 2 sim cards to share the mobile data above
• 700 minutes of voice call to any network each month
• 1 landline that can also call use the 700 minutes above to call

I'm trying to set up a resilient network (always on, always connected) network to maximize my usage of the offer above. My thoughts are as follows:

1. A router that is capable of handling multiple internet connections (i.e., fiber + mobile data)

Basically, this is a router that I should be able to connect one of the 2 sim cards and the fiber internet. Ideally, the router should do a quick and automatic failover from fiber to the mobile data (30GB offer) in case there's a downtime in fiber. Given the number of construction projects in Dar, we are seeing a number of incidents involving accidental fiber cuts and therefore fiber outages that can take a few hours to resolve.

2. A portable Uninterruptible Power Supply (UPS)

This would ensure the above router is always online. When TANESCO power is off, the UPS should kick in and keep the connection running. This will also protect the router above from power outages.

3. Multi sim card phone or pocket 4G/5G router

The other sim card should go into a phone with multiple sim cards. This should completely eliminate the need to buy separate data bundles from my current provider (Vodacom). Option 2, I could use a pocket router that will be with me at all times and keep me connected to the internet via WiFi.

4. A cheap landline

This can remain at home. Ideally for calling my kids at home (who I've not permitted to have mobile phones) when I'm at the office. Or for when the Mrs is away from her phone (happens a lot). Or for my kids to call me and speak to me (usually requesting me to get them some snacks when I come from office).

For those experienced in networking, can you share what kind of devices I need and what budget I should set for this?

A few things to consider:

• I'm not looking to spend more than 500,000-600,000
• No devices from American / European tech and network companies (Cisco, Ubiquiti, Mikrotik etc)
• Only Chinese tech (TP-Link, Huawei, Cudy, etc)
