Diary of a solid man-a beginner antennae in excess of high frequencies.

My programmer-engineer says that this program "compass-3d viewer v16.01" - can only watch and measure.- You can not edit the compass on this.. -that's what he says. I do not even know how to work on a "compass", especially since I am. I do not know how to work AutoCAD. Unfortunately, I do not have time to study these program

I'm at home. You give me this file - I'll try to open it. Maybe I do not understand you, this must also be taken into account.

WiMAX.TDD (Time Division Duplex). No need to use different frequencies for transmission and reception, allowing for more optimal use of allocated bandwidth (for 802.16 e is 5, 7, 10 MHz for 802.16 d it is possible to use 20 MHz).

FAQ

How can I check where my traffic is going / which computer uses the most traffic?

Why UPLOAD speed is lower than DOWNLOAD speed?

This is due to a technical characteristics of TDD LTE technology. In addition, higher speed Download is more demanded than Upload. We have optimized our network in order to give our customers the highest Download speed for a more comfortable user experience.

Was the answer helpful?

They do not know that they have fdd?

I am very, very sorry for my duplication of my question elsewhere. Sometimes I think - as if I understand little. Hence my doubts. So I want to double-check. It's a shame to me. A good word.

The first experimental samples of the mimo "Jomy" antenna. Of course, this is semi-artisanal, hand-made. But, there is no other option. Especially no radom. Tomorrow I will check SWR

[Admin 2484]

To the formidable people, you have overwhelmed me with your perspicacity,

for that you receive all my admiration .. !!!

 

Bravo, you are great ... !!!

[Admin 2484]

Erkin, this would be an almost perfect geometry for a reflective box

 

[Admin 2484]

And here's the result, with a tronconic box,,,,

Friend-teacher, Admin, I'm surprised at the frequency 2367 - SWR 1.16 ........ at a frequency of 2397 - in the picture everything is visible. I did not suggest that the first measurements of the Jomy antenna would be like this. By the way - I'm also a good student and performer. Long live Admin! Glory to Admin!
Of course, still need to check for the coefficient of amplification and cross-polarization. That's not for long.

[Admin 2484]

Erkin and my friends, you have done a wonderful job, you get my whole appreciation and keep it so ... !!!

[chilanzar2 85]

It is fantastic! Boss, you are great !!!

[Admin 2484]

Erkin, as Anritsu says, I think I will have to change some antenna dimensions. So you have to wait a bit ... !!!

WiMAX license to 2305 – 2320MHz, and 2345 – 2360MHz(2312,5+2352,5/2=2332.5MHz)

So the work center frequency should be 2332.5MHz

[chilanzar2 85]

This is the far-port. I removed and approached the strip lines to the reflector. I think it's better this way. Cross-polarization will improve. SWR was not worse, but everything is normal.

On this line of adaptation try to position some insulating spacers with final stiffening with your "gun"

[chilanzar2 85]

Hot melt in the heat - depresses. You need to think up another. I will think

Huawei B593S-601  This modem is used by our company. The manager says, and assures that they have a system running on TDD. Frequencies 2367-2397 ..- the Uzbek state issued a permit.

Why...??/

Router Huawei B593 LTE CPE is the 4G broadband communication device (LTE) fourth generation (4G) with full-duplex communication, using a time and frequency division (TDD, FDD). 

Operating frequencies:

* 2G: EDGE/GPRS/GSM 850/900/1800/1900 MHz

* 3G HSUPA / HSDPA / UMTS / DC-HSPA+ 900/2100 MHz

* 4G LTE TDD FDD 800/900/1800/2100/2600 MHz

And where is the 2300MHz band....????/

These are the dimensions for two working frequencies

A new form of WIMAX-Antenna

[chilanzar2 85]

These fools insist that they have the LTE-TDD system. They have an antenna with two cables. Apparently, they invented a new LTE-TDD system with two cables. They refuse that their antenna is a FDD. I do not even know what to do. Jomy, our antenna is better than their antenna. The tests showed excellent results. The band of the amplitude-frequency characteristic is very narrow.

[Admin 2484]

My friend, they can say whatever they want but we see our business,,,!!!

I was thinking of adding a director element to the antenna, what do you say ... ??

[Admin 2484]

,,,see this..

Slsoft, a friend from Latvia, did that....
