ZTE MF822 4G Modem VS ZTE MF823 4G Aircard

Since more and more people are using 4G network for their home or office, they improve the communication efficiency through high network connection speed. As one of the important telecom equipment sipplier, ZTE had releases many 4G Aircards for various operators. And more and more people know ZTE and ZTE 4G modems.    

ZTE MF822 and MF823 are two of the hot 4G dongles. ZTE MF823 is the world's slimmest 4G USB dongle. Due to the compacity requirement, the inner part of a 4G modem usually contains more contents so as to fulfill more functions and high demand for network. This feature makes 4G dongle in bigger body than 3G modems. ZTE optimized this feature and let MF823 in slim size, actually, some predecessor model of ZTE MF823 is also very big, many users feedback they don't like the big body..

 

ZTE MF823 4G USB Stick is now available for O2 contract, the O2 LTE USB 4G could support 4G LTE FDD bands 3/7/8/20 (800/900/1800/2600MHz), which is for Germany 4G network. However, the unlocked ZTE MF823 would in other European countries, such France, Portugal, UK, Switzerland, Netherlands and Finland. Most of the 4G network frequency bands are similar, which makes the roam of ZTE MF823 come true. What's more, ZTE Mf823 could work with most 4G operators in Asia and Middle East.    

By the way, unlike the first generation 4G dongle from ZTE, MF823 is in compact USB design, the USB can't rotate. The other model ZTE MF822 is one special one, it's a 4G USB Modem for North America. It could support 4G LTE frequency band 4 and band 7 (1700/2100/2600MHz), which is mostly deployed in Canada and USA. ZTE MF822 is already available for Canada operator "Rogers". To work with Rogers, the FCC certificate is necessary for the device. As we know, ZTE MF822 is the only model that combines 4G band 4 and band 7. So unlocked ZTE MF822 could work in Canada and also roam to work with some operators in USA. Frankly speaking, ZTE MF822 could also work with the operators in Asia and Europe who provider the LTE band 7. So MF822 is also powerful in the compatibility with global operators.

   

ZTE MF823 and MF822 are not brother models, but they are both LTE category 3 USB modem. They both support the peak download speed up to 100Mbps and upload speed up to 50Mbps. The speeds are amazing for the user to trip or surf outdoor, if you want unlock MF823 or MF822, welcome to visit http://www.4gltemall.com/4g-usb-modem/zte-4g-lte-modem.html .    

ZTE MF820T TD-LTE Modem VS ZTE MF820D FDD-LTE Modem

Most of ZTE 4G modems looks the same, and the first generation of ZTE 4G Dongles are all using same appearance design, so it becomes much harder to identify them. No wonder what the difference between them is. We open the blog especially for clear out the similar 4G devices and let users know more about the details of the LTE modems they had used.    

ZTE MF820T and ZTE MF820D are two similar 4G LTE sticks for first generation ZTE 4G USB modems. Most of the modems, appearance similar or not, their difference are mainly on the core part, that is the platform chipset, which decides what LTE frequency bands that could support and where they can be used.

 

ZTE MF820T is based on Qualcomm MDM9600 chipset, it could work TD-LTE bands 38 and band 40 (2300/2600MHz). ZTE MF820D is based on Qualcomm MDM9200 chipset, it would support FDD LTE band 3, 7 and 20 (800/1800/2600MHz). Unlike ZTE MF880, they can only work on single TD-LTE network or FDD network, MF880 would support LTE dual-mode (TDD&FDD).    

As the typical features of ZTE first generation 4G USB stick, there is no external antenna connector in the dongle, so the LTE MIMO transmission can't make true. But there is built-in antenna which is still reliable to connect network in high speed.

 

What's more, there is no MicroSD card slot available in MF820T and MF820D. We suppose they are not for single user, it's more like designed for large data in project test or other research terms. However, the 4G aircard may be more reliable when there is no SD card sharing function. According to the experience in 3G modems, SD card usually causes the application of wireless dongle in trouble.    

And we can see the big body of the 4G modem ZTE MF820D and MF820T is not user-friendly. It's almost twice bigger than ZTE 3G modems. We hope there will be some smarter or slimmer models available in near future, and this will not only need the improvement in the design for inner part, but also the function more powerful.
