Will you choose Vodafone K5005 or ZTE MF820D?

In most cases, if you have a look at a Huawei 4G USB modem, you can also the similar model from its competitor ZTE, we don’t know whether Huawei followed ZTE or the contrary, but the two vendors are playing more and more important role in global telecom market.

 

Today, we will compare two similar LTE FDD modems Huawei K5005 (also name Vodafone K5005) and ZTE MF820D.

 

Vodafone K5005 is a customized model from Huawei, the factory model number is Huawei E398 4G LTE FDD TDD multi-mode Data card. Vodafone changed the UI of this modem to its classic red color, which looks much cooler than the other Huawei E398 branch models.

 

 

ZTE MF820D is the derivative model from ZTE MF820. Also with the rotatable USB design, it’s in big sharp.

 

 

LTE Spectrum

 

To support Vodafone 4G LTE network in Germany, Huawei K5005 could work on FDD frequency 800/2600MHz. ZTE MF820D could work on FDD band 800/2100/2600MHz, which let it support more operators. Of course, it could also support Vodafone 4G network in Germany.

 

 

External Antenna Connector

 

 

Here now, most USB modems have built-in antenna. So do Vodafone K5005 and ZTE MF820D. To gain better signal so that users could surf in higher speed, MIMO technology is used to meet this demand. The obvious feature of MIMO is that there are two external antenna connectors.

 

 

We could see that Vodafone K5005 has double external antenna ports, with two pigtails; the 4G modem will provide amazing speed. However, follow the design of ZTE MF820, there is no port in MF820D.

 

 

Frankly speaking, the modem with external pigtail hole would be better than modem without antenna connector. To gain better signal and high surf speed, you will need the external antenna. But if you don’t use them, it would be the same to choose any of them. Because in our testing, the test speeds are almost the same under same networking conditions.
