Have you or your customers ever faced situations where internet access was urgently needed — but there was no fixed broadband, no WiFi, or the WiFi signal was simply too weak?

For example:

• While traveling, you want to transfer photos from your camera to your phone, but there’s no WiFi nearby.
• During exhibitions or business trips, the local WiFi is unstable, yet you urgently need to join a video conference with clients.
• During outdoor live streaming, several devices need internet access simultaneously, and some devices only support Ethernet connections instead of WiFi.
• You need to temporarily install surveillance cameras in a warehouse for real-time monitoring, but there’s no available network.
• And many other similar scenarios.

So, what can be done?

Is MiFi the Perfect Solution?

For many people, the first thing that comes to mind is using a MiFi device.

Indeed, MiFi devices can solve many networking problems in these situations. However, they also introduce several new challenges.

1. Built-in Battery Issues

Most MiFi devices come with built-in batteries, which bring concerns related to:

• Safety risks
• Transportation restrictions
• Certifications and compliance requirements
• After-sales service issues

We frequently see news reports about battery swelling, overheating, self-ignition, or even explosions in battery-powered devices. For suppliers and distributors, this creates significant after-sales risks.

In addition, shipping battery-powered products is more complicated and costly, as many logistics channels impose restrictions on lithium battery products. Importing and exporting such devices also requires additional certifications and regulatory approvals.

2. No Wired Network Support

Another limitation is that MiFi devices only provide WiFi signals.

But what about devices that do not support WiFi, such as:

• Traditional security cameras
• Printers
• POS terminals
• Industrial equipment

How can MiFi provide internet access to these devices?

Then Why Not Use Traditional CPE?

Some people may say:

“Then just use a traditional CPE device — no battery, and it supports Ethernet.”

Yes, traditional CPEs can solve the issues that MiFi cannot. But they also come with their own disadvantages.

1. Poor Portability

Traditional CPE devices are usually:

• Larger in size
• Equipped with external antennas

This makes them inconvenient for travel. They are difficult to fit into backpacks or luggage and occupy much more space. External antennas can also easily be damaged during transportation.

2. Power Supply Limitations

Most traditional CPE devices require DC 12V power adapters.

This means users must:

• Carry a dedicated power adapter
• Find a wall outlet whenever using the device

These limitations greatly reduce deployment flexibility and restrict usage scenarios.

So What’s the Ideal Solution?

MiFi has limitations. Traditional CPE also has drawbacks.

To solve these problems, the R&D team at SmileMbb developed a brand-new MINI CPE solution — the XMC1842.
