Why HUAWEI E398u-11 4G LTE FDD USB modem is Hot?

Here now, many customers are looking for Huawei E398 4G LTE FDD USB modem, the accurate model number is Huawei E398u-11. However, due to the supply shortage, many customers have to wait for the new stock arrival, and they would never will to change other similar modems. Then someone may ask: why Huawei E398u-11 is hot in the market?  

 

 

Usually, the frequency band that a 4G USB modem could support is important for user to choose and decide whether it is appropriate for specific areas or countries. Let's have a look at the frequency band that Huawei E398u-11could support, it works with 4G LTE FDD 1800/2100/2600 MHz.  

 

 

 

The FDD band 2600 MHz is the common band for FDD, and band 1800MHz is the most popular band, so there are many 4G USB dongle could support them. They are not the focus from customer, then the Band 2100MHz is the focus from customer, because comparing with the previous two bands, few modems are available on the market to support this band.  

 

 

 

Another factor is also important for users: the external antenna connector. And there should be two antenna connectors available in the modem. Actually, Huawei E398u-18 also support band 2100 MHz, but most customers don't change to E398u-18 because there is only one external antenna connector. The single pigtail can't finish the task for MIMO connection.

 

   

 

The third factor is that Huawei brand. As the most professional vendor for USB modem, Huawei is always the most trustful brand not only for 3G USB dongle, but also on 4G LTE Surfstick.  

 

   

 

Now that Huawei E398u-11 is in shortage, which 4G modem would be alternative foe replacement? Below are the some models for consideration:    

 

Huawei E392u-6:

- 4G LTE bands: FDD 2600/2100/1800/900Mhz

- 3G UMTS: 900/2100Mhz
