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

 

Vodafone 3G 4G Mobile WiFi – R201, R205, R210

Many customers know there are various USB Surf sticks available for Vodafone 3G or 4G networks, but few know the mobile WiFi hotspot for Vodafone. Today, we will have a review of Vodafone Pocket WiFi for 3G & 4G networks.

 

 

The early model of Vodafone mobile WiFi is Vodafone R201. It’s the first generation for Vodafone and also the first generation of Huawei mobile WiFi. This model is produced by Huawei, follow R201, Huawei presents many new versions to publicly and gained gear success. Vodafone R201 supports HSDPA 7.2Mbps, it could transfer SIM signal to WiFi signal and up to 5 users could access internet via R201. At that time, the download speed 7.2Mbps is good enough for most activities, but with the network development and many applications for data transmission, this speed can’t meet the requirement for surfing. Then newer version comes out.

 

 

Vodafone R205 is the newer model supporting HSPA+ technology. The HSPA+ apply the MIMO technology for data transfer. So it would obviously improve the link speed. Vodafone R205 could support peak link speed up to 21Mbps and 5.76Mbps. It comes from the factory model Huawei E586 mobile WiFi. Similar to R201, it would support 5 users to share the WiFi network. As we can see, the improvement of the new generation mobile WiFi is on the supporting speed.

 

 

However, People demand for speed is not limited to 21 Mbps. Higher connection speed are required in many areas. Then 4G technology is decoupled and the mobile terminals are following. Vodafone is always leading the industry trend.

 

 

Here now Vodafone R210 4G LTE mobile WiFi is available. Under good 4G LTE network, the R210 supports up to 100Mbps. It’s really amazing, if you download a movie in big size, it would take for only few seconds. And this speed makes it true to play many online games.

 

With more power capacity, Vodafone R210 could work for longer time than its predecessors. What’s more, more users (up to 10 WiFi enabled devices) could get connected with the mobile WiFi and surf. The pocket WiFi could only work on 4G LTE network, but also back ward 3G UMTS/WCDMA & 2G GSM/GPRS/ EDGE. Where 4G network is not available, Vodafone R210 would auto choose the alternative good network available to keep user connected with network. With higher specification, there is no doubt that the price of Vodafone R210 is a little bit higher than the previous R201 and R205.

 

 

Considering the performance of the three mobile WiFi for Vodafone and budget, you can choose the right model to keep connected with the best networks.

Vodafone K5006Z ZTE 4G LTE Stick Specifications

 

Network Bands

 

The new model Vodafone K5006Z supports all relevant Web standards. In LTE, it could work on  LTE 800MHz and LTE 2600MHz. In the latter case theoretical maximum download speeds of up to 100 Mbps and 50 Mbps in upload are possible. If LTE is not available, the stick could switch on UMTS and HSPA (DC-HSPA+). The quad-band operation for four GSM frequencies 850, 900, 1800 and 1900 MHz is provided. Even abroad, the stick should almost always provide good reception.

 

 

Optics and other features

 

The panel is held in the Vodafone typical design, so setting with red border. However, compared to the K5005, the sequel looks a bit clumsy and not quite as elegant. But that is a matter of taste and a score is up to you. Same with almost all surf sticks, the dongle K5006 with an additional memory card to USB memory can be upgraded. For this purpose, the device offers a MicroSD slot. Corresponding maps are mostly cheaper than USB flash drives with the same storage capacity.

 

Under adverse reception conditions, high speed could reach by one or two TS9 connector (MIMO) antennas plug it. Just outside of urban areas, this can be very helpful, such as in tourist areas. Also noticeable is the lower weight. Instead of 40 grams (K5005), it weighs 10 grams less. With 90 x 27 x 18 mm, it is also slightly narrower and deeper dimensions.

 

 

 

Those who still does not have a LTE Stick, the 4G LTE Surfstick K5006-Z is considerable. And there are unlocked Vodafone K5006Z to use any SIM card, just one pay for the dongle and never limited to any contract. For those who have the predecessor, the newer, the better.

 

Conclusion

 

A completely ordinary stick, which brings all you need for the high speed data rates needs.

 

 

Unlocked Vodafone R210 4G LTE Router Review

The mobile hotspot router for LTE users
Since early August in 2012, Vodafone offers the R210 mobile Wi-Fi hotspot with built-in battery, which could work with GSM and UMTS and LTE networks. Today, we get the unlocked Vodafone R210 here for test review. Unlocked means it’s not limited to Vodafone SIM card, it could support other operators’ SIM card when the network frequency band is compatible.

 

First impression

In the package you will find next to the Vodafone R210, there are a USB cable and an AC adapter to charge the battery at the socket. If desired, the device can also be charged directly to the USB port of the computer.

The device itself is about the size of a cell phone and weighs, on the basis of very generously a battery of 3000mAh capacity, a little more than other mobile hotspots. Unfortunately, the battery is permanently installed in the device, so it cannot be easily changed by the user. The casing is made entirely of plastic. However, the R210 is well in hand. The side of the device you will find the power button and the button for the WPS encryption, which makes the wireless connection to computers significantly. In addition, a small reset button has been installed – it is right next to the microUSB port to charge the battery.

 

Also on the other sides of the R210 are the slots for the SIM card and a microSD memory card type. If desired, an external antenna can be connected. For the usual TS9 port is hidden behind a cover.

 

Operation of Vodafone R210

The operation of the Vodafone R210 is actually quite simple; it is not immediately clear what position the SIM card to be inserted into the device. Although it displays a small icon next to the slot as it goes, but the icon is extremely small and barely visible. A magnifying glass might help! If you have inserted the SIM card then you have to do is to run the hotspot with a short press on the power button. Then chooses the R210 into the best available wireless network – ideally, of course, the LTE network, if available locally. Connection settings, such as the APN must be entered only when a SIM card from another provider is used – which is generally no problem, because the Vodafone R210 is SIM unlocked. Vodafone cards generally require no configuration.

 

 

General information about the current wireless connection will be displayed directly on the screen of the Vodafone R210. These include the online time, the data volume, the current battery charge level or the network technology that is being used by the device. On request, you can also use a corresponding app for Apple iOS or Android smartphones and tablets, download from the respective app store and view the data directly on the smartphone. If you want to make any major settings, but this must still be done via the web interface in the browser. To this are added in the address bar “vodafonemobile.wifi” and after entering the password “admin” are various configuration options given. It can be determined, for example, that the mobile hotspot only uses the LTE network and not to fall back to the 3G or 2G network.

 

 

Power and data rates

Let’s talk about data rates. Technically speaking, the Vodafone R210 is perfectly equipped: The integrated modem LTE can handle up to 100 Mbit/s download and affairs up to 50 Mbit/s upload, and if the network and mainly used the plan, this also allows for data rates. In the UMTS network figure is still 43.2 Mbit/s based on the possible data accelerator DC-HSPA+. In a pinch, of course, also the 2G network can be used – here, then with EDGE about 250 kilobits per second.

 

 

 

In my test, I used a SIM card from Vodafone, which supports up to 50 Mbit/s downstream. In addition, tests were conducted in the telecommunications network; the SIM card is limited to 100 Mbit/s. In 4G mode (LTE), it quickly became apparent that it is not about the power or the rate is the limiting factor, but the wireless interface of the Vodafone R210: more than 30 Mbit/s are possible. A look at the technical data also opens soon discover why this is so: While the router supports Wi-Fi to the current n-standard, but only with a maximum of 72 MBit/s – which explains the low net data rates. That’s a shame, but for most users, 30 Mbit/s is also likely to to be perfectly adequate. In the UMTS network in the telecom, Speedtest incidentally reached almost 28 Mbit/s. A use of a modem via USB is not possible; the USB port is only for power.

 

Conclusion for Vodafone R210 4G Hotspot Router

The reception of Vodafone R210 is absolutely fine, but sets no new standards – in LTE and UMTS network, it could beat Vodafone K5005 4G Surfstick. Nevertheless, the reception is better than most smartphones. The internal battery is 3000mAh with pocket size and it kept six and a half hours of continuous use in test. This is considerably longer than most by keeping other mobile hotspots.

 

To sum up, the Vodafone R210 is a highly recommended device. Finally it is a mobile hotspot, with LTE, UMTS and GSM combines all three wireless standards in one device and also confident in continuous operation.  The Vodafone 4G Mobile Wi-Fi R210 allows you to connect to the internet with 4G speeds of the smartphone, the tablet, or laptop.

Will you buy Huawei E589 or Unlocked Vodafone R210 4G Pocket WiFi?

It has been a long time since Huawei E589 and Vodafone R210 available in the market. But there are still many users who haven’t gotten their 4G mobile WiFi.

 

Today, we will have a general review of the two similar 4G LTE mobile WiFi. Huawei released Huawei E589 at the beginning of 2012, then Vodafone customized this factory model per its preference, then Vodafone R210 was presented to public.

 

 

Vodafone R210 4G Pocket WiFi was first available in European areas for Vodafone 4G LTE network.  With Vodafone logo below the screen, it looks cool. The classic combination of red and black color makes Vodafone R210 attractive. However, following the factory model of Huawei E589, Vodafone R210 has only one external antenna connector, which may not be a good solution for MIMO. The battery is inserted and cannot be detachable. But the battery is rechargeable with capacity of 3000mAh, which could support the R210 to work for 6 – 8 hours.

 

 

Here comes a question, what’s the key difference between Huawei E589 and Vodafone R210? Are they just different from the logo? It’s a good question.

 

 

Vodafone R210 is for the commercial 4G LTE network from Vodafone in Europe. So when Vodafone ordered R210, it set R210 to support its deployed 4G LTE frequency band 800/1800/2600MHz. However, Huawei E589 is the model in Huawei brand, so it’s not limited to any network, per the specification, we found it would work on 4G FDD 800/900/1800/2100/2600MHz, which covers almost 80% 4G FDD network available now. Based on good reputation in 3G mobile WiFi, Huawei E589 4G LTE pocket WiFi will lead the market demand.

 

 

 

So Huawei E589 would support more operators over the world, unlimited to Vodafone. Per current sales record, Huawei E589 is the most popular mobile WiFi for 4G LTE network, especially in Asia and Europe. The good news is that there are unlocked Vodafone R210 available in 4gltemall.com , it means Vodafone R210 could not only work with Vodafone 4G network, but also support the 4G FDD network operators in other countries or areas. And the price is better than Huawei E589, so if you like Vodafone R210, and don’t want contract, to buy an unlocked Vodafone R210 from 4gltemall.com is a good idea.
