There is no curator in the subject. For questions about filling caps, please contactauto RU in QMS or moderators section through a button under the messages. How to do it right, what would you understand the first time, well describedhere. Finally it is time to give an extended description of the device.
1. Element base modem:
The ATHEROS 9341 processor clocked at 533 MHz.
64 MB ROM memory implemented on EM6AB160TSE-5G
USB HUB controller on GL805G HH1JEOGY37
8 MB flash memory on MX 25L6433F chip
Power supply JW50225 GP838CK
Enclosure connectors - RJ-45
SIM card slot
All plug connections are IP66 protected.
The power supply circuit is protected by a switch against polarity reversal of the input supply voltage.
There is an indication of the mode of operation of the modem, consisting of 8 LEDs.
The router comes bundled unpretentious, no frills, clocked at 2.4 GHz
Element base:
MTK7628 processor
Flash memory
25L8006 E
WAN - 1x10 / 100 Mbps WAN port (RJ45)
Lan - 2x10 / 100 Mbps Ethernet port (RJ45)
2 x WI-FI antennas
The power supply is common to both devices - the allowable output voltage is from 5 to 18 volts.
Continued Description:
The modem is controlled by a web-muzzle. Despite the English-language interface, there are no problems in the settings. Of the useful “goodies”, one thing is especially pleasing - the URL filter, which is just as relevant for the mobile Internet. A simple rule is created with a ban on a specific page and voila, goodbye paid subscriptions. For two months of work, not a single write-off :) The rules are created separately for each resource, not a list, but you do not have to do this often, so it's worth it. Again, there is no need to use third-party sites, such as noip, to organize such a service.
There are no USSD commands in the interface, but I would not count it as a minus, well, no and no. I could not check the maximum distance between the outer and inner parts of the device - in fact, in my case, the cable length was 35 meters. On the other hand, it is difficult to imagine a mast with a height of 10 storey house.
The overall impression of the modem is purely positive - the device is easy to operate and reliable in operation. Due to the price, the modem is not very popular, but the ability to distribute a pair of modem router at a very large distance makes it in some cases the only option for organizing communications. This is especially true for cases where the house is located in a lowland or in the presence of tall trees in the direction of the base station. The design of the remote module provides for mounting on a wall or on a mast / pipe, fasteners are included. I don’t know, however, what will happen with a lightning strike and how to organize lightning protection, but this is the topic of another section, not related to a specific model.
A small minus in the translucent case of the router, the LEDs shine with such force that in the dark the case resembles a Christmas tree.
I did not find any firmware for this model, yes, and did not see any need. The device turned out to be easy to operate, like an iron - turned on and working, i.e. lovers of various improvements it will be just uninteresting. Those who want to change IMEI will have to invent something of their own - DC Unlocker is not an assistant here.
Of course, I am not an authority on the forum, but in my opinion the device is worthy of finding its niche and is recommended for purchase.
P.S. I completely forgot about the "rate of fire" of the device. The photo shows the results of SpeedTest, but you should not accept this data as an axiom. In general, the speed depends not so much on the signal level, but to a greater extent on SINR (noise level) and BS load. In my case, the result shown refers to the time from 1:00 and later. During the day, the speed is lower than once every two or three due to the active work of awake users. True, it is possible to manipulate the operating frequency with the range settings in the modem. So, with an incoming speed of 10 mbit / s in the 4G range, switching to 3G gave a result of 28 mbit / s. Those. all "hooked" on 4G in anticipation of high speed and released 3G.
