Comparing Embedded EVDO vs. Dedicated Devices

Embedded EVDO vs. Dedicated Cards

You might be considering buying a new laptop with an embedded EVDO device. Well you might want to re-consider. Here are eight reasons why buying a dedicated device is a wiser purchase.

1. Carrier - The embedded EVDO device is locked to a specific carrier, so you won't have the freedom of choosing between Verizon or Sprint. What if that carrier doesn't have great service in your area? Too bad!

2. External Antennas & Amplifiers - If you find places that you often lose connectivity due to low signal, or wish your signal strength was better, you can't connect an external antenna or amplifier to boost the signal with an embedded device. All of the dedicated cards that we sell have an external antenna port which allow you to connect an amplifier and external antenna.

3. Long Term Use - You can only use the EVDO connection on the laptop with the embedded EVDO device. When you buy a new laptop in a few years, you will have to buy a dedicated device, unless your new laptop just happens to have an embedded device as well.

4. Multiple Computers - With an embedded EVDO device, you can only use the EVDO service on the laptop with the embedded device. If you have a dedicated device, like the USB720, you could use the EVDO service on ANY computer with an available USB port!

5. Routers - With a dedicated device, you can connect it to an EVDO router and share the connection to all of your computers via WiFi or ethernet.

6. Replacement - If your embedded EVDO chip dies or need to be replaced for any reason, you will be wishing you had purchased a dedicated EVDO device instead. Having the chip replaced is a big ordeal, when I contacted Sony Vaio support about having the chip replaced, they suggested that I purchase a service & repair manual to manually replace the chip myself. I don't think many of us want to open a laptop computer which has very small and delicate parts to replace an EVDO chip. Not to mention I couldn't even find a replacement EVDO chip online to purchase as a replacement. So I've come to the conclusion that replacing one of these embedded chips is nearly impossible. Do you really want to have your entire laptop replaced just so you can use an embedded EVDO device?

7. Connection Manager & Firmware - With an embedded EVDO card, you can't use the carriers connection manager. You must use the connection manager that is provided by the manufacturer. This means that you will have to wait for the manufacturer to make updates to the connection manager and firmware, and thats not a top priority for them! With a dedicated device, you use the carriers connection manager, and its a top priority for them to have the latest features and support available (This can be a support nightmare).


8. Rev-A - Most embedded cards are Rev-0, unless you just purchased a new laptop with a Rev-A embedded device. This means you won't be able to take advantage of the Rev-A network, which improves download & upload speed, as well as lower latency times.
