Huawei E5573 LTE MiFi Hotspot Review

More and more huawei new 4G models are available now. We get the latest Huawei E5573 4G mobile hotspot for speeds of up to 150 MBit/s in the LTE network. In addition to a fast modem, Huawei E5573 offers useful functions such as dual-band Wi-Fi, wireless extenders and connectors for external antennas. Thanks to compact dimensions and low weight, the hot spot is ideal for use on the go.


Huawei E5573s-320, this is the exact model number of new mobile hotspot. It’s delivered in a small cardboard box without lots of accessories. In addition to the router, you can get only another short micro USB cable for charging or to connect to the computer. In addition, there is a 1,500 mAh strong battery included in the box, which you must insert into the router after the SIM card plugged in.

The first impression is good overall. The device weighs 100g which is significantly less than most smartphones. The Huawei E5573 is available either in black or white, the entire body is made of plastic. Unlike many other Huawei mobile LTE hotspots, on the front of E5573, there are only two LEDs to indicate the operating status.


The Huawei E5573 supports LTE up to 150 MBit/s in the downlink and up to 50 Mbit/s in the uplink, if the network available allows these speeds. If there is no LTE is available, of course, the older 2G and 3G networks for internet access can be used via UMTS with DC-HSPA+ up to 42.2 Mbit/s in the downlink. The Huawei E5573 is well suited for use in many countries in Europe, Australia and Asia. However, the E5573 device is not particularly well suited in North America due to limited support for the frequency ranges used there. In LTE, the Huawei E5573s-320 supports the frequency bands 800, 900, 1800, 2100 and 2600 megahertz while on UMTS, the device works on 850, 900 and 2100 MHz.

In the test I could reach speeds of up to 130 MBit/s in the downlink and 45 Mbit/s in the uplink via LTE, which is almost peak speed for a Cat4 terminal. If with LTE Cat6, device could achieve higher data rates, but this is not supported by Huawei E5573. Even the current IPv6 is not supported. The reception was in the LTE network at 1800 MHz and 800 well. If necessary, you can connect an external antenna to Huawei E5573. There are two stand TS-9 connectors under a cover available. Below is the recommended 4G External antenna for Huawei E5573, you can refer the image and link to buy:

Huawei E5573 has a removable battery of 1500mAh, and the operating time is about 6 hours. Of course you can also charge the hotspot during use and thus extend the working time. You can use the E5573 directly via the USB interface, a software needs to be installed, only one driver. The operation completely without the battery is not possible.

As a mobile hotspot, the Huawei E5573 could provide the wirelesss connection to mobile devices such as smartphones, tablets or laptops. The Huawei E5573 uses either wireless on 2.4 GHz or 5 GHz, by default the connection to 2.4 GHz is preconfigured. In particular, at events and fairs, however, we recommend the use of 5 GHz WLAN, because this frequency range is usually utilized significantly less. WiFi 802.11ac is not supported.

 

Like many other current LTE hotspots from Huawei, such as the Huawei E5770 or the Huawei E5377, there is a WiFi Extender function. This makes it possible to use an existing Wi-Fi network as an Internet access. Wireless Extender also allows the automatic switching of the connection of wireless access to Wi-Fi, so you can the router on the way to work.


The web interface of the Huawei E5573 is already known by many previous devices and differs neither in design nor in functionality from previous releases. On the home page, which can be accessed via the IP address 192.168.8.1, there is a good overview of all the relevant connection parameters. Furthermore, there is the possibility to send and receive text messages as well as to update the firmware from the Web. In the settings you can configure, for example, the wireless connection, the often used guest network by some users. Also in the mobile settings, it’s lacking an important feature: you can not adjust “LTE only” or “3G only” in Huawei E5573, but simply turn on and off the possibility of LTE. This was achieved significantly better than Huawei previous models.

 

The control and configuration can be done via the web interface in the browser, there is also the Huawei Mobile WiFi HiLink app as an application for Android and iOS smartphones and tablets. Only Windows Phone users will unfortunately empty, for this operating system, there is no special app.


The Huawei E5573 is a good small LTE router, which you can buy without hesitation. Although the device has no LTE Advanced Cat6, but is still fast enough for most users and is suitable also excellent, with dual-band Wi-Fi for fairs and events. The replaceable battery and the terminals for an external antenna also among the plus points. As an alternative, for example, the Huawei E5377 and Netgear Aircard 782s(with Display), both devices are roughly the same price. Those who prefer to have a slightly stronger battery, should refer to Huawei E5770 or Huawei E5377T. And if you prefer LTE cat6, Huawei E5786 would be a good alternative.

 

Huawei E5786 4G LTE Cat6 MiFi

Many people are using the most popular Huawei E5776 4G Mobile WiFi Hotspot. It’s the world first LTE Category 4 MiFi that supports maximum download speed to 150Mbps. With the 4G LTE is more and more applied in our lives, Huawei is becoming one of the most well-known 4G Pocket router till now.

 

 

 

However, this is not the end. A few months ago, Huawei released a new generation mobile WiFi hotspot: Huawei E5786. This is the world’s first LTE Category 6 MiFi. With upgraded chipset and functions, Huawei E5786 will dominate the Cat6 terminals. Then what’re the main upgraded functions?

 

Before we introduce the details of Huawei E5786 and E5776, we should introduce some features and difference about LTE Category 6 and 4. The table below shows some main features of them for your reference:

 

 

3GPP release

User equipment category

Maximum L1 datarate downlink

Maximum number of DL MIMO layers

Maximum L1 datarate uplink
Release 8 Category 1 10.3 Mbit/s 1 5.2 Mbit/s

Release 10 Category 8 2,998.6 Mbit/s 8 1,497.8 Mbit/s

 

 

 

From the table, we can see the LTE Cat6 could fulfill the peak link speed up to 300Mbps, almost the double of the LTE cat5. Now you may know the difference between Huawei E5786 and E5776. Under perfect network environment, Huawei E5786 could achieve the downstream up to 300Mbps.Based on current technology; this wireless connection speed is really amazing! That’s the top selling point of E5786.

 

 

 

So is there other difference between E5786 and E5776? With LED screen showing important information for the mobile WiFi, they both support maximum up to 10 wireless terminals to access internet based on huawei own brand chipset. There is no doubt that Huawei E5786 is with latest, better chipset than E5776, even the best Huawei chipset till now.

 

 

 

 

The size of E5786 is a little bit thicker than E5776, and they both have external connector. We believe Huawei E5786 will also have the various sub-models like E5776. But we haven’t gotten such information. The battery capacity of them are large enough for almost 6 or more working hours, Huawei E5786 battery is more powerful with better performance after optimization and chipset grade. We will keep update about the Huawei E5786, please keep follow if you are interested in this pocket WiFi.

 

Vodafone K5006Z VS Vodafone K5005

We had noted that Vodafone K5006Z is already available on the market with tariff for users, somebody may have some memory about the previous model Vodafone K5005. Yes, you are right, they are both LTE Stick for Vodafone 4G networks. But if you want to buy a LTE Stick for Vodafone SIM card, which one to buy? What’s the difference between them? Which one is better? To ask these questions, it proves you are a serious buyer. Many people just buy the 4G sticks with the contract without the corresponding concern. But if you want to buy unlocked LTE Stick, you may concern which one you can benefit more.

In this article, we will see what the difference between the two models is and which one is better. Vodafone K5006Z is available later than K5005, but they are both customized by Vodafone in red and white appearance. Below is the table listing the specifications of Vodafone K5006Z and Vodafone K5005:

From the table above, we can see that the main difference between the Vodafone K5006 and K5005 is the manufacturer. Vodafone K5006 is manufactured by ZTE, so it’s also called Vodafone K5006Z; Vodafone K5005 is from Huawei. The second difference is dimension, the size of the 4G modems are similar. We have to mention that both of them are with rotatable USB connector, which will save much space for users.

So we can conclude that the two modems are very similar in function and performance based on the same chipset. If you prefer to Huawei or ZTE Brand, you can choose the modem on their brands.

Huawei E5786 VS ZTE Flare LTE Cat6 MiFi

Since more and more operators launched theor 4G LTE network, the end users could access the wireless network in high speed for suring. The new technology improves the quaility of our life in almost every aspect, however, when more and more industies apply this technology, the basic 4G network seems not enough for high data requirement. The lucky thing is that thechnology is developing to find better solution in our life: LTE-A technology is bound to provide higher data transmisson.

 

We had introduced many LTE category 4 or CAT 5 USB stick and WiFi router, they are born to support the wireless speed for 100 or 150 megabytes per scend. But the vendors didn’t stop here. At the beginning of 2014, two LTE category 6 mobile WiFi were presented to public. They are Huawei E5786 and ZTE flare.

 

Before we introduce the two new terminals, it is necessary to have a review about the LTE categories and their corresponding connection speed that could be achieved. Below table shows the data information for reference:

 

 

 

On the table, we can see the LTE category 6 can provide the support for 300mbit/s downlink speed, which is the double of current CAT5, and three times than CAT3. Huawei E5786 and ZTE Flare are the two new gadget to achieve this fantastic link speed.

 

So here comes a question, if my ISP provides the LTE Cat6 network, which one is better between the Huawei E5786 and ZTE Flare? To answer this question, we must first know their functions and difference, which will help us to make the right decision. Then what’s the main difference between them?

 

We can compare below the main features of them:

Model Number

From the table above, the features are very similar except the Chipset and supported WiFi users. Huawei E5786 is based Huawei own brand Hisilicon LTE Cat6 chipset while ZTE Flare is running on Qualcomm latest Gob 9×30 chipset. We can’t conclude which chipset is better, after we get the device, we will test the function. Theoretically, Qualcomm chipset is better than Huawei, which also decides the high cost of ZTE Flare. The second one is Huawei E5786 support maximum 10 WiFi users while ZTE Flare could support 32 wireless terminals via WiFi.

 

It seems ZTE Flare is more powerful than Huawei E5786, after we get the price quote, use will make a balance between them.

Difference Between Huawei E2130 and E2131

Huawei E2130 and E2131 are the world’s first 3G SD modems, which was released at CES 2014. They have the main function to memorize data as datacard, one special feature is added by Huawei. They also have the SIM card slot for wireless connection. The NANO SIM card could be inserted into the datacard and after plug the card to PC or tablets, the PC or tablets could access internet through the 3G SIM card based on the SD card.

Here now Huawei E2130 and E2131 could maximum download speed up to 21Mbps, which is enough for most applications. But since the Data card is already in small size, so nano sim card could be used to save more space.

Huawei E2130 and E2131 are both in SD card size, but Huawei E2131 is larger in size to 37 mm length, while E2130 is 32mm. This is the first difference. The second difference is that the network frequency bands. Huawei E2130 supports 3G single band 2100MHz. It seems to be a common version. Huawei E2131 seems to meet different areas because it support dual-bands, and it has many band combinations, such as 900/2100MHz, 850/2100mhz, 850/1900MHz and 900/1900MHz.

 

The third difference is on the power consumption, which is also a big concern for users. Huawei E2130 normally consumes power ~300mA/3.3V @0dm, and maximum 500mA/3.3@ 22dBM. With larger size, Huawei E2131 normally consumes ~300mA/3.3V @0dm while maximum 630mA/3.3@ 22Dbm.

 

Below are the specification details and difference for reference:

Difference Between HUAWEI E5776 and E5372

With the 4G LTE network development, more and more 4G LTE Category 4 devices are available. HUAWEI is always leading the mainstream of LTE trend. And more and more Huawei wireless devices are available. Today, we will have a look at the Huawei E5776 and Huawei E5372 4G mobile WiFi hotspot, the two very powerful mobile and wireless routers. They are both available on the 4gltemall.com now.

You may wonder where the exact advantages and disadvantages of each device are, you will see the details in following article. A common feature is the integrated cellular modem: both the HUAWEI E5776 and the HUAWEI E5372 is based on HiSilicon Hi6920 chipset which is for the LTE Category 4 with up to 150 MBit/s download speed. In addition, the modem is backward compatible with UMTS DC-HSPA+ technology and including GSM/EDGE.

 

Differences 

As we can see, the Huawei E5776 is in black color and made of plastic, but in China, the model HUAWEI E5776 is in white; and you can also see the Huawei E5372 is either black or white appearance, and with removable battery. This has some advantages, but the capacity of the E5372 battery is only 1780 mAh, which seems too much lower compared to 3000 mAh of HUAWEI E5776. This becomes apparent in the operating time: Huawei E5776 provides up to 10 hours of wireless Internet access, about 4 hours more than the E5372.

As the table shows, there is another difference: the Huawei E5372 wireless module transmits as desired in either the 2.4 GHz band or the 5 GHz range. Especially for large events with dozens of Wi-Fi networks so you have an advantage with the E5372, because the terminals of course also support the 5 GHz band. Furthermore, a repeater mode has been integrated in the E5372, so you can also use a different wireless network for Internet access when needed. Both devices have a limitation of connecting up to 10 WiFi users, in addition, an eleventh device can access the Internet with the MiFi router via USB cable.

Release In Quarter 4. 2012 In Quarter 4. 2013

 

 

For users who usually use their mobile LTE router in stationary, an external antenna can be useful. Here is important to note that only the Huawei E5372 has the necessary connections for the two MIMO technologies. The Huawei E5776 only has one TS-9 connector and is suitable only for UMTS antennas.

Conclusion

You decide which device ultimately, is a matter of taste. The Huawei E5776 has the advantage of significantly more powerful battery while the Huawei E5372 is technically more powerful in data transmission. At the main component, i.e. the modem, but both devices are absolutely equivalent and well equipped for the future.

More detailed information on the two devices you can get in the next article about test for the Huawei E5776 and Huawei E5372. Good to know: the Huawei E5776 mini is also available as a telecom Speedbox LTE, it costs a little less, but also slightly different frequency bands. Also the Huawei E5372 is cheaper available under a different name: Vodafone sold the unit from the 4th Quarter of 2013 under the name of R215 in its stores, also the frequency bands differ marginally from the original device.

HUAWEI E392 4G LTE Stick

The latest LTE stick E392 is from the Chinese manufacturer Huawei, as one of the most popular and best 4G modems, HUAWEI E392 is available for many operators worldwide.

HUAWEI E392 Not available in Germany

 

So far, Huawei is the major vendor for LTE and had supplied the major LTE network operators in Germany. Previously, HUAWEI had supplied the Speed Stick LTE for Telekom, and the K5005 for Vodafone, they are from the factory modem named Huawei E398. HUAWEI E392 is actually not a typo, it’s a newer model with a lower number than the older model E398.  The original HUAWEI E392 4G Stick (without logo of Vodafone or Telekom) so far is not available in Germany. Users could get it from 4gltemall.com . The compact USB stick is also LTE Category 3 USB Stick and could completely replace HUAWEI E398.

 

 

 

The stick E392 supports casually pretty much everything that is common to worldwide radio standards. In LTE (4G), E392 stick supports the frequency bands 800, 900, 1800, 2100 and 2600 MHz. Here, in Germany rather LTE800, 1800 and 2600 are relevant. So the HUAWEI E392 could work with other European countries 4G networks. Also the 3G spectrum is almost completely covered. The E392 supports UMTS at 900,1900 and 2100 MHz in the standard DC-HSPA+/ HSPA+/ HSDPA and HSUPA. In the 2G networks users can access in the bands GSM 850/900/1800/1900MHz (Quad-band).
Based on the LTE technology, the E392 could transmit data with both FDD and TDD. These are two different duplex methods. For FDD (frequency division duplex), which is common in Germany, there are 2 separate frequency bands to use to send and receive data simultaneously. For TDD (time division duplex), the sending and receiving transmitted on the same frequency band, but slightly delayed. FDD is to be found mainly in Asia. E-Plus also experimented with the technology, and this could perhaps bring in the future for use in Germany.

 

 

Anyone who uses a mobile LTE deal can theoretically explore the full power of the stick. This is a 100 Mbps stick for the download and it can be transmitted with a maximum of 50 Mbps. The HUAWEI E392 has provided two slots (MIMO) for connecting an external antenna. This often brings significant advantages in weak reception areas. The expandability via microSD card (up to 32GB) is now practically available. At just 40 grams of weight is also quite easy to take in hand or pocket.

 

 

Conclusion

 

The Huawei E392 is the perfect travel companion based on the huge range of supported standards. Those who usually travel the world will never be disappointed.

ZTE MF91T 4G Router VS ZTE MF91S Mobile Hotspot

If you have many electronics in pocket and want them all access Internet, it’s a good idea to have a mobile pocket WiFi hotspot. Since 4G is becoming the mainstream, more and more 4G pocket WiFi is optional for users. As one of the wireless terminals supplier, ZTE has many mobile hotspot for users, such as ZTE MF91, MF91T, MF91s, MF91D etc… Many people feel confused by the model numbers.

 

 

Most times, we see the ZTE mobile hotspots are in the same blue package, from the 3G mobile hotspot to 4G, no new design element could be found. In the aspect, ZTE is not doing well. User can only see the model number from the back stick and can’t identify the broadband difference.

 

 

If you have ZTE MF91T and MF91s, you may be unable to tell from them. You may know they are both 4G TD-LTE mobile router, but what’s the really difference between then?

 

 

Usually, the main difference between the mobile hotspot is on the frequency bands. ZTE MF91T hotspot could support 4G TD-LTE band 38 and 40 (2300/2600MHz) and 3G HSPA+ 900/2100MHz. ZTE MF91S could also support TD-LTE band 38 and 40. What’s more, it also supports TDD band 39 (1900MHz) and FDD band 7(2600MHz). ZTE MF91s is specially for Chinese operator “China mobile”. So these 4G bands are for 4G network in China, and MF91s supports 3G TD-SCDMA & 2G GPRS.

 

 

The frequency band that the pocket WiFi supports is the main concern. Since the LTE technology difference, the connection speed may vary. ZTE MF91T could support maximum download speed up to 68Mbps while upload speed to 17Mbps. Since ZTE MF91s is a TDD/FDD dual-mode mobile hotspot, when working on TDD mode, ZTE MF91S could reach same speed as MF91T, but when working FDD mode, MF91s mobile router could reach peak download speed up to 100Mbps and upload speed to 50Mbps. From this aspect, we can see LTE dual-mode mobile hotspot is more flexible to adapt to the network environment.

 

 

 

Other features are almost the same because they comes from the same design, inner part is modified to suit different LTE networks. If you want unlocked ZTE MF91T or MF91s, welcome to buy from www.4gltemall.com

 

Unlocked Telstra USB 4G (ZTE MF821) 4G USB Modem Review

Today, we get a new 4G LTE USB datacard, the 4G aircard model number is ZTE MF821. The 4G modem is packed well in a box, there is the operator’s logo “Telstra USB 4G” on the front box, and the information is telling user this 4G USB modem. The ZTE MF821 is already unlocked by our group, so users don’t need worry about the lock issue.

 

 

At the side of the box, we can see that LTE Frequency bands that ZTE MF821 could work with. The specification indicates MF821 could support FDD LTE 1800/2600Mhz, but per our information from the manufacturer ZTE, the modem MF821 4G aircard could support band 1, band 3 and band 7(1800/2100/2600MHz), we suppose this band is not activated because the operator Telstra is not providing the LTE band 1 (2100MHz).

 

 

 

And the 3G DC-HSPA+ Tri-band (850/1900/2100) is backward compatible. Under the 4G LTE network, user could enjoy high speed up to 10Mbps. Even on 3G network, ZTE MF821 could reach speed to 42Mbps.

 

 

 

Open the package, we can see the 4G dongle ZTE MF821. There is a logo of “4G” and “T”, which means Telstra 4G. On the side, we can see two small icon of signal; they are two hidden connectors for external antennas. This feature is important for 4G data transmission, and it lets MF821 different from MF820 or MF820T. On the other side, there is no slot.

 

 

 

The USB of ZTE MF821 is rotatable for 180 degree, user could hide the USB in the body of MF821. User need open the back over and find the SIM card slot. On the SIM slot, we can see the model number, IMEI number, place of origin (Made in China) and manufacturer ZTE Corporation. And close to the SIM card slot, there is a slot for MicroSD memory card. The MF821 could support maximum 32GB SD memory card.

 

 

 

Comparing with other ZTE 4G Aircard, such MF880 or MF820D, ZTE MF821 is really very slim, the size of MF821 is as big as a 3G datacard.  So if a user prefer a small size USB dongle, ZTE MF821 is a good option and without any contract. But before purchase, user should concern about the 4G frequency band  compatibility, if you want a 4G Aircard for FDD band 20 (800MHz) or TDD band 38 (2300MHz), or any other bands that are not same as MF821 supporting, you may need check other model and choose the right one.
