What’s the difference between ZTE MF880 and ZTE MF820S2?

As one of the 4G LTE modems from ZTE, the TDD modem ZTE MF820s2 may not be well known because it’s born for China Mobile 4G LTE networks. ZTE MF820s2 looks very similar to ZTE MF820, they are using the same appearance module, but inner parts are completely different. ZTE MF820 is for FDD network while MF820s2 works for TDD & FDD.

 

 

There is another 4G TD-LTE modem ZTE MF880, which is also FDD compatible. Today, we will have a look at what’s the difference between ZTE MF820s2 and MF880.

 

 

Frequency Bands

 

 

Frequency band should be the key difference between similar 4G modems, even though some modems looks almost the same. The frequency band decides where could work or not, and which operators they could support. ZTE MF820s2 supports FDD 2600MHZ and TDD 1900/2300/2600MHz. The band 1900MHz is a special band that very operator has chose as their 4G network spectrum. So many other 4G modems could replace ZTE MF820s2 if the band 1900MHz is not a must frequency. ZTE MF880 could also support TDD 2300/2600 MHz, but it cannot work with band 1900MHz. As a TDD and FDD surfstick, ZTE MF880 also supports FDD800/2600MHz. So when users don’t require modem to support 1900Mhz, ZTE MF880 could fully replace MF820s2.

 

 

4G LTE Speed

 

 

As standard 4G USB modems, ZTE MF880 and MF820s2 both supports the TDD and FDD network. However, under the two technologies, the data transmission rates are different. When working on FDD network, the peak download speed could reach 100Mbps while upload speed up to 50Mbps. But if on TDD networks, maximum download speed could reach 68Mbps and upload speed could reach 17Mbps. By the way, the speeds are only theoretical speeds. In real practice, the network can’t be perfect as we wish; the link speeds may vary time to time.

 

 

 

External Antenna and MicroSD card

 

It’s a pity that both ZTE MF880 and MF820s2 both don’s have connector for external antenna. And we didn’t find any place to plug the MicroSD card. So they couldn’t use as flash memory card.

 

 

 

USB Design

 

ZTE MF880 and MF820 are both under design of 2D USB design. The USB is rotatable for 270 degrees. This design will help users to use more space when plug to PC.

 

 

We can’t make conclusion that which is better. They are in same brand and could meet different requirements from users or operators. So it would be better to know more about the difference between similar models. If you want to check more 4G LTE modems, welcome to land www.4gltemall.com

 

ZTE MF880 4G LTE FDD TDD Modem Review

ZTE had release many 4G modems, such as ZTE MF820, MF820D, MF821, MF821D, MF820T, MF820s2 and MF880 etc.. And many 4G mobile WiFi are available now on the market. Today, we get the ZTE MF880 4G Modem and we will show the details for readers. Hope you will know more about this modem ZTE MF880.

 

 

Logo and USB Interface

 

The ZTE MF880 is with logo “3”, which means it’s customized by the UK operator “3”.

 

 

Like ZTE MF820, ZTE MF880 also has a rotatable USB interface; the USB could be hidden in the body of the modem. And beside the logo, there is a small indicator in oval shape, which will help users to know more about the connection status.

 

 

Back

 

On the back, the model number MF880 is printed on this modem. With the model number, there is CE number, RoHS mark and below them is the IMEI number of this modem, which is on behalf of the modem’s ID. The IMEI number is printed on the back cover, unlike ZTE MF820, whose IMEI number is on a extra stick. And it also show the original produce place “Made in China”. ZTE also print its brand with this mark.

 

Inner Part

 

Beside the indicator, there is a little cap to open the back cover of ZTE MF880. But you may take effort to open. At this point, the modem is not user-friendly. The cover is very tight. After opened the modem, you can find the SIM card at the side of the body. But there is no slot for memory card. And it’s a pity that it also doesn’t have even one external antenna connector. In 4G LTE technology, the MIMO connection is one of the most important features for high speed data transmission.

 

 

Network bands

 

According to the official files from ZTE, the ZTE MF880 4G LTE Modem could support 4G LTE TDD and FDD bands as follows:

 

* LTE FDD DD800/2600 MHz

* LTE TDD 2300/2600MHz

* 3G UMTS 900/2100MHz

 

So unlocked ZTE MF880 could support all the operators who had launched Band 20, band 7, band 40 or band 38. ZTE MF880 should be one of the LTE modems which could support TDD and FDD simultaneously. If you want to buy unlocked ZTE MF880, welcome to land www.4gltemall.com .
