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

- Two external antenna connector    

 

Sierra Wireless AirCard 320u:

- LTE 1800/2600 MHz

- WCDMA 850/900/2100 MHz

- Two external antenna connector  

 

ZTE MF820:

- LTE-FDD 1800/2100/2600Mhz

- 3G UMTS 900/2100Mhz

- No external antenna connector  

 

So if you can’t wait and urgent for project, the above three models could be taken into consideration or replacement.

Huawei E398u-18 4G LTE FDD USB Modem Review

Comparing with Huawei E398 other branch models, such as Huawei E398u-11, E398u-1 and E398u-15, Huawei E398u-18 should be a special one, it's not because Huawei E398u-18 has different appearance as other models, it's due to Huawei E398u-18 supports the special FDD LTE band 8 (900MHz), which is rarely deployed per current 4G network situation.

According to the GSA report about 4G LTE network, the Band 8 (900MHz) is only available in few countries and areas, such as KT Corporation in South Korea, Telenor in Sweden. And in the market, few 4G modems could support this band. Huawei E398u-18 is one of them.

Today, we get the Huawei E398u-18 4G LTE FDD Surf stick with Telenor logo. Telenor is the provider in Europe and provide 4G network in three countries: Hungary, Norway and Sweden.

 In the three countries, Telenor provides different LTE frequencies as below:   Hungary: FDD 1800MHz Norway: FDD 2600MHz Sweden: FDD 900/2600MHz     So to save cost, Huawei E398u-18 could support all of the bands/Spectrum above: 4G LTE FDD 900/1800/2600MHz   With same appearance of E398u-11 and E398u-15, Huawei E398u-18 has only one external antenna connector at the side Micro SD slot. If user wants to use data card with MIMO technology, E398u-18 may not be a good option.

Like other E398 Modems, Huawei E398u-18 could also work with 3G UMTS network and 2G GSM/GPRS network: 3G UMTS band is 900/2100MHz and 2G qual-bands. And the rotatable USB is classical features of Huawei E398.

As the brother model, Huawei E392 4G FDD TDD multi-mode data card also has one similar model, the model number is Huawei E392u-6. HUAWEI E392u-6 supports 4G FDD 900/1800/2100/2600 Mhz, which seems more powerful than HUAWEI E392u-6.   If you want any of them, welcome to buy it from www.4gltemall.com .

HUAWEI E392u-12---- The Most Popular Surfstick of HUAWEI E392 4G USB Modem

As the flagship of 4G LTE USB Modem, HUAWEI E392 4G LTE Multimode USB Modem like a big tree, derives many branch models, such as HUAWEI E392u-12, HUAWEI E392u-21, HUAWEI E392u-22, HUAWEI E392u-92, HUAWEI E392u-6, HUAWEI E392u-9, HUAWEI E392u-511 etc… They are for different operators in different areas, so they incorporates difference modules to support various 4G LTE bands.

[/caption] Based on good quality and reliable performance, HUAWEI E392 4G LTE Modem is the first option for many network providers. Which one is the most popular model?

 

Before we give the conclusion, let us talk about the 4G network deployment status. From the beginning of 2012, operators all over the world are planning and starting deploying the 4g networks. At this trend, the providers in Asia seems running faster than European operators. Perhaps it’s due to the economic depression in European area.

 

Per the report of 4G network status, LTE technology is most commonly adopted to use in data transmission. And the LTE Band 1800Mhz is most commonly deployed spectrum, 38% current LTE networks choose 1800Mhz (Band 3). It’s the refarming of GSM 1800Mhz. As we know, GSM is the most common 2G network. And per our information, Band 7(2600Mhz) is also the common FDD network in Europe and APEC areas. Then we look back to HUAWEI E392. The brand model works on band 3 and band 7 has two models HUAWEI 392u-12 and E392u-6.

[/caption] In this case, we could conclusion that HUAWEI E392u-12 is the most commonly used 4G LTE Surfstick. If you are a professional journalist or other professional who usually travel between countries and need fast data transmission, it’s necessary to take HUAWEI E392u-12 around. Frankly speaking, comparing with 3G USB modem, HUAWEI E392 seems a little large, but compare with digital camera and luggage carrier, it’s slim enough. 4GLTEmall.com could offer unlocked one.
