What’s the difference between HUAWEI E5331 and HUAWEI E5220?

At the beginning of 2013, we found Huawei released a new pocket WiFi on CES 2013. At the first sit when we see it, we thought it was Huawei E5331 3G 21Mbps Mobile WiFi, because from the outside appearance, it's completely the same as Huawei E5331.  

 

However, after we read the specifications on the stick, we got to know we are wrong. It's the new mobile WiFi hotspot Huawei E5220. Then here comes a question: why did Huawei release a same model with different name?  

 

On the stick beside the demo of Huawei E5220, we read that Huawei E5220 supports single, dual or triple UMTS bands by its variant model. This feature is also specified on Huawei E5331.Huawei E5220 supports maximum download speed up to 21.6mbps, and upload speed to 5.76Mbps. It's also the same as E5331.    

 

The key feature of Huawei E5220 should be the link time. It says Huawei E5220 could network in 5 seconds with HiLink technology. HiLink is a new user-friendly system that users don't need install any software or setup any parameters, once the device with HiLink technology connects the supported gadgets, the gadgets can then start surfing freely.  

 

It's obvious that this system brings much convenience for customers and save much time. Take a example, in the past, if you use Huawei E372 and plug it to PC, it would take around 1 or 2 minutes to install the driver in the modem; after driver installed to PC, you need to setup the parameters, such as Profile, APN, dial number etc... and if there is something wrong in the settings, you may can't get connected to Internet. With HiLink technology, it would completely change this situation, once you plug the Huawei E3251 HiLink USB stick to PC, the PC then get connected in 5 seconds, no driver installation, no setup. And you can manage the modem through Web UI.  

 

Huawei E5220 also follows this rule. After the WiFi enabled devices get connected to E5220, they can surf in 5 seconds, or slower in 10 seconds. No setup and driver are needed. In our opinion, this should be the revolution for this new pocket WiFi.    

 

 

What's more, Huawei E5220 supports maximum 10 users to share the network while Huawei E5331 supports 8 users.  From the above two upgraded features, we can see Huawei E5220 has different system from E5331 and it also improve the user experience and functions.

HUAWEI E3276s-151 4G LTE Cat4 USB Stick Specifications

As the first LTE Cat4 USB Modem in the world, HUAWEI E3276 attracts the eyes of the world when it’s first released by HUAWEI, the top telecom equipment supplier from China. The typical feature of the LTE Cat4 is that the LTE devices could support maximum download speed to 150Mbit/s, which increase the 50% speed than the current LTE speed. This speed is even 10 times faster than 3G.

   

Under this speed, users could surf and link to internet in awful experience. What’s the more, HUAWEI E3276 supports 3G and 2G simultaneously, with 3G and 2G backward, the modem could auto switch to the lower network. The UMTS network can achieve up to 84 Mbps download speed due to DC-HSPA+ technology.

 

   

 

Just like HUAWEI E398 and E392, HUAWEI E3276 also has many variants models, such as HUAWEI E3276s-150, HUAWEI E3276s-151, HUAWEI E3276s-152, HUAWEI E3276s-210, HUAWEI E3276s-500, HUAWEI E3276s-601 and HUAWEI E3276s-920 etc…They support different frequency bands to meet the requirement of various operators in many countries or areas. HUAWEI E3276s-151 should be the most popular model, because it supports the popular 4G LTE Spectrums all over the world: 800/900/1800/2100/2600 MHz. And it has been presented to the public by the provider Megafon (Model Number: M150-1) and Vodafone( Modem Nuber: Connect Pen K5007)

 

Below are the details specifications for HUAWEI E3276s-151:  

* 4G LTE FDD 2600,2100,1800,900,800 MHZ

* supports LTE Downlink 150 Mbps

* 3G HSPA + / HSPA / UMTS 2100, 1900 AWS, 900 MHz

* 2G GSM, GPRS, Edge 850, 900, 1800, 1900 MHz

* Built-in antenna

* Uplink 50 Mbit/second (4G)

* Downlink 150 Mbit/second (4G)

* Output for external antenna - 1st For signal reception and 1st for increased bandwidth

* Slot for micro SD cards up to 32GB size (optional)

* Slot for SIM card

* Supports Windows 7 Sp1, SP2, XP SP2, SP3, VISTA SP1, SP2, and MAC OS X 10.5,10,6

ZTE MF880 and MF820T 4G LTE TDD USB Modem

As one of the most important 4G vendors, ZTE has released many 4G LTE modems. ZTE MF820T and MF880 are two of the popular TDD models.  

 

Just like other 4G LTE modems from ZTE, ZTE MF880 and MF820T followed the same design as ZTE MF820 4G LTE FDD Surf stick. The modem body is a little bit larger than usual 3G USB stick. And taking them in hand, users can feel the weight is more than 3G modems.

 

   

 

What is a pity that both ZTE MF820T and MF880 don't have the connectors for external antenna. Perhaps at the big inning when engineer designed the mode, they didn't take this factor into their blueprint. As we can see, in the serials of ZTE MF820D, MF821, MF821D, MF820S2, MF820T, MF880, they all incorporates no antenna ports. As the key features of MIMO connection, we are afraid it may not be as good as the modems with MIMO antenna for data transmission.

    

 

ZTE MF820T and MF880 both work for 4G LTE TDD network, perhaps due to for different providers, they support different TDD frequency bands as below:    

 

ZTE MF820T 4G LTE TDD Single Mode USB Modem:

* Single mode LTE TDD 2300/2600MHz  

 

ZTE MF880 4G FDD TDD USB Modem:

* FDD 800/2600MHz

* TDD 2300/2600MHz

* DC-HSPA+/HSPA+/HSPA/UMTS 2100/900MHz

* EDGE/GPRS/GSM 850/900/1800/1900MHz

   

This should the key difference between ZTE MF820T and MF880. Per current information, ZTE MF880 had need presented to public under provider "3" from UK. And ZTE MF820T should be for China Mobile. What should focus is that ZTE MF880 could also support FDD LTE band 800/2600MHz. It means MF880 could switch between FDD and TDD networks, so ZTE MF880 is somewhat like a enhanced ZTE MF820T.      

 

Regarding the data transmission speed, they both support download speed at 68Mbps and upload at 17Mbps under TDD –LTE network. ZTE MF880 seems more powerful because when working at FDD network, the peak speed could reach to 100Mbps for downlink while uplink could reach 50Mbps.  

 

In conclusion, ZTE MF880 seems more powerful than ZTE MF820T, so if you want to want buy ZTE 4G LTE TDD USB Modems, welcome to www.4gltemall.com
