3 solutions for WiFi in your car
For a wireless network outside the home, you'll need cellular internet. Mobile WiFi works via 3G or 4G. Just like wired internet, mobile WiFi can't be faster than the connection the Internet comes on. To use WhatsApp, send email, and surf to news sites and blogs, 3G speed is sufficient. Planning to stream music or videos? In that case, I recommend 4G or 4G+. You can get a data plan for this or use a prepaid data SIM card. The latter is especially handy to avoid high costs when driving outside the Netherlands.
1. WiFi via portable router
A MiFi router is a mobile WiFi router that allows you to take 'your WiFi' with you anywhere. A MiFi router can supply up to 20 devices with WiFi. Because you'll place a SIM card inside a MiFi, you won't need a network cable. A power cable isn't required either, because MiFi routers have batteries. A MiFi router with a USB port can often be used as a power bank too. That way, you can carry your WiFI with you even outside of your car. For example when attending a business meeting, or going to the beach for a relaxing day off.
2. WiFi via car charger
Only planning to use WiFi inside the car? Go for a solution you can attach to the car battery. That way, you won't have to worry about your battery running out. The Huawei CarFi is currently the only product that can do this. You can attach this device directly to your car lighter. These 4G routers allow you to connect up to 10 devices to the Internet wirelessly, so all passengers can connect their tablets, smartphones, and laptops to the Internet.
3. WiFi via USB WiFi dongle
Your car doesn't have a cigarette lighter, but it does have a USB port? In that case, plug a WiFi dongle into the USB port to give your car WiFi. Of course, you can also opt to plug the dongle straight into your laptop. Already got a WiFi dongle, but don't have a USB port in the car? Use a car charger to connect the dongle.
Prefer WiFi via your phone?
Prefer to use your phone's data bundle? Create a WiFi hotspot and share the connection from your smartphone. The tethering function lets you share your phone's 3G or 4G signal with others.
Note: your phone antenna is often weaker than the antenna on a WiFi device.
