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.

Band 20 (LTE 800MHz-Digital Dividend) – Operators and UEs

LTE 800MHz is also called Digital Dividend spectrum and 4G LTE Band 20. FDD LTE Band 20 is paired to allow simultaneous transmission on two frequencies. The Uplink frequency is 832-862MHz and downlink frequency is 791-821 MHz. The Width of the band is 30MHz, duplexing spacing is -40MHz and band gap is 71MHz. The duplex configuration is reversed from the standard, having the uplink higher in frequency than the downlink.  

 

LTE Band 20 has been chosen by many operators as their 4G LTE Spectrum, expecially in Europe areas and now many 4G LTE USB Dongle/modem/Surfstick, 4G LTE CPE for band 20, and you could check below the 4G LTE Mobile router and 4G LTE Modulefor band 20.

Unlocked Rogers LTE Aircard 330U from Sierra Wireless General Review

You may had seen a 4G LTE Modem which support 4G Band 4(1700/2100MHz) or 4G LTE Surfstick which is for 4G FDD Band 7 (2600MHz), but do you know any 4G USB modem that could support them together?

 

Today, we will recommend a 4G Aircard which could support the 4G LTE FDD Band 4 and Band 7 simultaneously. The model number is Rogers AirCard 330u LTE Rocket Stick. This is the successor of Sierra Wireless AirCard 320u. They are both from Sierra Wireless. The difference between them is that Aircard 330U is capable of LTE FDD Band 7 and Band 4, but AirCard 320U could support band 3 and band 7.

 

 

 

The Rogers LTE AirCard 330u looks cool in red color, but it's unlocked to Rogers network. It means the AirCard 330u could support any operators' SIM card.     Just like the brother model AirCard 320u, 330u is in square shape and it's bigger than AirCard 306 or 308. The USB could rotate for 180 degree. On the front, There is logo of Rogers and one the back, there is printer of "4G LTE" on it. Below the "4G LTE", we can see the icon of the manufacturer "Sierra Wireless" logo, and the indicator of data transmission.  

 

 

 

Open the back cover, we could see there is a stick indicating the model number "AirCard 330u" and the IMEI number of the 330u. Belie the stick, we can see the SIM card slot and MircroSD card slot. At the side of the SIM card slot, there are two external antenna connectors for MIMO. They are covered by two small cap, user need open the cap and then connect the external antenna.

 

 

 

The connector of the external antenna is TS-9 model, so if you want buy external antenna for AirCard, you could check here: http://www.4gltemall.com/external-antenna-for-huawei-4g-l...  

the 4G Antenna is also usable for Aircard 320U and 313U. 

 

 

After plug the two external antennas, the data link speed would improve obviously. The AirCard 330u is apt for North America 4G LTE networks band 13 and band 7, so it could also roam in Europe or Asia. In conclusion, AirCard is a cool USB modem that will be a good gadget for 4G networks.
