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 8	Category 2	51.0 Mbit/s	2	25.5 Mbit/s
Release 8	Category 3	102.0 Mbit/s	2	51.0 Mbit/s
Release 8	Category 4	150.8 Mbit/s	2	51.0 Mbit/s
Release 8	Category 5	299.6 Mbit/s	4	75.4 Mbit/s
Release 10	Category 6	301.5 Mbit/s	2 or 4	51.0 Mbit/s
Release 10	Category 7	301.5 Mbit/s	2 or 4	102.0 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 B3000 LTE Category 4 WiFi Router

The Vodafone B3000 LTE Router is available in stores now. The device is the successor to the Vodafone B2000 , which came on the market in spring 2012. The highlight of B3000 is the support for LTE with up to 150 MBit/s in the downlink and 50 Mbit/s in the uplink (LTE Category 4), in addition, the router can be used for calls via VoIP. The design is largely identical to its predecessor, and also the target group has not changed: Vodafone offers the B3000 primarily business customers.

LTE Category 4 and VoIP
On the back and on the sides of Vodafone B3000, we can find all sorts of connections. The four LAN ports connect to network-enabled devices and two RJ11 connectors allow the connection of analog phones. Furthermore, two USB connections for the integration of a printer or USB storage device available and under a cover there are two connectors for external antennas (type: SMA). For example, the LTE reception quality can be improved by the LTE MIMO antenna . On the front, various LEDs indicate the operating status. The user can see at a glance, for example, the signal strength and network technology here.

The Vodafone B3000 LTE router is manufactured by Huawei and it carries on the model number of Huawei B593s-22. Besides LTE Category 4, the modem allows UMTS including DC-HSPA+ (up to 42.2 Mbit/s) and of course GSM/EDGE. The supported frequency bands include the 800 MHz and 2600 MHz for LTE used by Vodafone, if there are more bands are supported, it is not clear from the documents at our disposal. But we are sure that the original model Huawei B593S-22 would support the LTE FDD 800/900/1800/2100/2600MHz & TDD 2600MHz.

The WLAN module operates at 2.4 GHz and supports up to 32 simultaneously connected Wi-Fi devices. According to the manufacturer Huawei, the power consumption of Vodafone B3000 is under 12 watts.

Price and Availability
According to Vodafone, the B3000 LTE Router available until early April in the Vodafone online shop as well as in retail stores(www.4gltemall.com for unlocked version). However, some traders already now offer the B3000 with prices. But it’s better to get unlocked one before purchasing, the unlocked one would use with any other operators besides Vodafone.

Vodafone Launch LTE Category 4 Stick

Vodafone offers LTE network now speeds up to 150 megabits per second (LTE Category 4). The speeds are initially available in the cities of Dusseldorf, Munich, Dortmund and Dresden, but are offered in the coming weeks in other cities. It is important to note that the 150 Mbit/s can be achieved only through LTE2600, in the well-developed network LTE800 only about 50 Mbit/s are possible. The smartphone tariffs and data tariff through Vodafone Mobile Internet Flat 50.0 can use the higher speed at no extra charge.

The hardware for Vodafone is from Chinese manufacturer Huawei. As the first smartphone with LTE Category 4 is the Huawei Ascend P2 in the Vodafone shops, the first USB surf stick with LTE Category 4 is the Vodafone K5150H, which is also manufactured by Huawei. Might come in the next few weeks to other smart phones and modems, it is speculated, that the iPhone 5S (or whatever it is called) already support LTE Category 4.

Many of the customers may of course ask the meaning of 150 Mbit/s whom you look at the availability and the rates. My opinion: on the one hand, it is for Vodafone a great marketing tool for some users, it is certainly important to be able, at least theoretically reach 150 Mbit/s. On the other hand, the total capacity will be increased so that more people get good data rates simultaneously. And since I see the true sense: in places where currently LTE2600 is used, is expected anyway with a heavy load of networks.

In the coming days and weeks, the Huawei E3276 4G LTE Category 4 Surfstick will come available, and we will take a few tests on the Vodafone 4G network, so that data rates are achievable in reality. And we will have a clear review about the 4G LTE Category 4 network from Vodafone.
