LTE frequencies of Russian operators. Topic: B8 and B20 which is stronger? Which operators work on b20

I won’t argue about the curvature of the arms - this is of course very important. But facts are also stubborn things. About 4 years ago I purchased two Ziljian ZBT crash bars 16" and 18" (B8 alloy). The thicker 18" one is still alive, thank God, but the thinner 16" one with a good sound died exactly two years later (as I indicated manufacturer on the packaging). I buy a new 16" (exactly the same), but it lasts not 2 years, but only 1 year. I buy another one of the same kind and it, like a dog, also lives for about a year, and it didn’t even burst along the edge (as usual) , and in the middle of the field. With all this, we used to rehearse for 3-4 hours 2 times a week, but over time we switched to 1 time a week for a maximum of 3 hours. Are your hands also getting crooked? In fact, I think the quality has dropped a lot. So I decided to try changing the manufacturer.

Brass crash Amati lived 15 years, nickel silver Trowa cymbal lived 40 years, bronze ride (B8) Amati lived 20 years, bronze (B8) Leningrad hi-hat lived 30 years, B20 STAGG ride lived 15 years, Paiste PST 5 crash (B8) lived 12 years. And so on. What lives longer is a question only for the drummer. :)
Actually, I only broke one plate with my own hands, which was 25 years old. And only one Soviet plastic failed, the rest simply fell into disrepair, sagging. I play from metalcore, thrash and punk, to pop and folk music.

23.09.16 19:40:28

In my Paiste 2002 set there are cymbals that are over 10 years old and still intact (ugh ugh ugh)

and here's what else - budget cymbals, in which the sound is not structurally incorporated, last less, because young and inexperienced musicians beat the sound out of them, trying to make them sound at least somehow

23.09.16 20:57:39

Greetings! In addition to the wrong blow, which is the sin of many metallurgical rockers, who think that the sound must be knocked out of the cymbals, another important factor is the installation of the cymbals. Under no circumstances should crashes be delayed too long!!! The plate should swing freely!!! Even the top plate of the high hat! Well, again, correct sound extraction! And the conversation about whether bi 8 or bi 20 is better is absolutely nothing. We need to start with at least the difference in price. And we don’t even have to talk about sound. That's such a big difference.

24.09.16 09:17:59

Thanks everyone for the answers! I never attached any importance to this, but now, having specifically asked myself this question and scoured the Internet, I have no choice but to agree with you, colleagues. I’ve been playing for 5 years now, but I didn’t know such things. Live and learn! Thank you all so much again!!!

By the way, anyone who wants to add anything else on the topic is welcome! I'll read it with pleasure.

Especially the penny stagg, tempo and other kitayva. And also “buy a set for the price of a normal ride” from the Turks. And, as noted above, 2002, rud, giant beat is the lot of never-beginners, like the top Meinl from B8/B10/B12. The question of alloy is a matter of taste, but not price.

Of course, it’s a matter of taste, which a beginner has not yet formed, which is why he allows himself to be convinced that the B8 is also a professional hardware.

as Primus wrote above, the Paiste 2002, RUDE and Giant Beat cymbals are made from CuSn8 alloy, in other words B8 and this is professional iron.

26.09.16 18:28:11

Cymbals made from B8-based alloys are generally more durable. The amount of tin in the alloy affects not only the sound, but also the strength.

But there is an important nuance - you need to look at specific series of plates and their thickness.

With a "power" style of play, a professional HEAVY CRASH from B20 will most likely live longer than a budget THIN CRASH from B8.

And the fact that B8 is an alloy for non-professionals - many have already said that this is not true.
Most PAISTE series are made from B8, which does not make, for example, the 2002 series any less professional.

What is there to think about? B8 cymbals are for beginner drummers who have not yet fully decided whether they will quit playing tomorrow or the day after. Professional plates only at 20.

15 years on 2002 from alloy B8... Ippat, I'm an undecided beginner sucker. This Monday has begun))))

26.09.16 22:41:21

I don’t want to offend anyone, especially the owners of alloy B8 cymbals; if this happened, then I apologize. For me personally, the B8 topic has been closed for a long time. And I sincerely don’t understand what’s good about PAISTE 2002 plates. And I never have. IMHO PAISTE has cymbals that sound much nicer. I also understand those “old” drummers who bought 2002 in those distant 80-90s, when Amati was considered good hardware. And now they regret parting with them. And the ear got used to it. And you can’t sell them to anyone at a high price. And the memory of my younger years warms my soul. But now, when the choice of cymbals is huge, and you can try hardware for every taste, I personally cannot speak seriously about the beauty of the sound of the 2002 series.

Once again, sorry if I offended anyone. This is just the personal opinion of a professional sound engineer, who also plays drums for 28 years, but, unfortunately, still does not consider himself a professional drummer.

For hard rock they haven't come up with anything better yet.

Then you should know that the 2002 is one of the most versatile plates with a top (sand). that fit well into the mix. Unlike the new series of the same zilds and pasties (which sound very good) they don’t hang the “I’m a signyche series” egg out of the mix. Zilds have similar properties to "K", but they are much brighter.

27.09.16 08:52:03

Well, we've gone off topic again about which is better - iOS or Android, nothing changes. The original question was about the survivability of the plates, and not the superiority of some manufacturers/alloys/colors/sizes over others. Allow me to insert my two cents. Dear Topicstarter, I would pay attention to the sales section, at least within this forum. Approximately see how many crashes and teas cut in a circle are on B8, and how many on B20. Of course, this is a very inaccurate indicator. But anyway. I agree with what was said above about the overly forced game. If you want to chop trash with oak sticks 2B, then it’s better to select pieces of iron that are not the thinnest of the jazz series, although here Captain Obviousness already enters the scene.

27.09.16 13:52:18

Dear kullervo, can you tell me how I can optimize my search in the sales section? What should I enter into the site’s search engine and what should I pay attention to to summarize? As of today, there are 319 pages in the forum section in the kpl/prdam section - somehow voluminous... Or did I misunderstand you?

27.09.16 17:07:05

Bulky is not the right word, but very few things are served on a silver-rimmed saucer these days. I didn’t say that it would be easy =)) Here’s the thing - is there really an irresistible desire to find out what kind of plates are less brittle or just to hear the common phrase take %the name of any brand% they are awesome because they play %the name of a cool guy Drummer%, or another option, “the brand is nothing, the hands are everything,” I more than agree with the last statement, but my innate curiosity pushes me into the arms of mild insanity. In both cases, this is not an answer to the original question. But in order to really determine which iron is more durable, you need to conduct a normal experiment, and who can boast that they actually used a couple of hundred plates before they were slaughtered (and such a quantity for a good sample is nothing at all, we omit unnecessary details about the delivered blow , random and not very defective and other factors that will contribute to the test). But if you look at the average temperature in the hospital, that is, compare someone’s already broken iron, then you can get at least some picture.

As not only a drummer, but also the owner of a commercial rep database with an 8-year history, I can say some of my observations. I provide all clients with their own hardware. Initially I used Paist 2002 exclusively.
So crashes - there were three 14-inch ones, each lasted about 8 months in public use. 15-inch ones - there was one, 4 months. 16 inches were medium and power, 6 pieces, 3 of each - 6-7 months. 17 inches - 1 piece, 5 months.
Hi-hats - two crunches, 15 and 14 inches, a year and a half each, 1 heavy, second hand - a year, a new soundage - 1.5 years.
Ride - 1 piece, 22 inches heavy ride - 15 years (7 in personal and 8 in base))))).
Teas are 16 and 18 inches, three Wilds are 11 months each, 4 mediums are 11-13 months.
Oh, and a couple more Ores - tea 18 from hand, a year old, cut off, still holding to the norm for six months. Het - 3rd year, everything is fine
Istanbul Mehmet and Agop traditional, alloy B20 - hat 14th - 7 years, still alive.
Ride - 5 years old, they broke up when they started crashing for six months.
There are countless crashes, probably 20 of them, 16, 17 and 18 inches, none lasted more than 3 months, on average 2 months.
Zildzhan A custom, three crashes, one 15th and two 16th, all medium - 4-5 months.
Sabian AA, AAH, NN, NNH. Hat NN medium - 8 years old, crack in top.
Ride 20 NN medium - 10 years old, still alive.
Hat AA rock - 3 years old, alive.
HHH 16th evolution crashes are the most fragile - 4 months maximum, 3 pieces. NHH studio and NHH stage, 16th, two each - 8 months, the latter is still alive. AA rock crash 16th - two pieces, I sell before they break, but it easily lasts 8 months. AAHsplouzhn 16 - 5-6 months, 5 pieces. AAH studio 18th, 2 pieces, 8 months, the second one lasts more than 10 months. NN medium 16th year, 18th dark bank, therefore 5th year alive.
China AA 18th - two years, 16th one and a half years. NHH mini 14 and 16 are also fragile, 2 and 4 months, respectively.1

All frequencies, arfcn and bands are labeled on the diagram.

Table of standards in ranges:

Comments:

1. Attention, it’s 2019 and 4G/LTE can already work in all 5 bands! Even at 900 MHz, a network is already being deployed in the Leningrad region.
2. LTE Band 38 (2600 TDD) is used only in Moscow and Moscow Region by Megafon and MTS operators. In other regions, television operates on this frequency.
3. Yota essentially became the virtual operator of Megafon, i.e. where Megafon 3G operates at 900 MHz, Yota will operate at the same frequency, provided that the subscriber device supports this standard.
4. LTE Band 7 (2600 MHz) is used only in cities and large populated areas.
5. LTE Band 3 (1800 MHz), in my opinion, one of the most common will be in areas with an average density of “dacha residents”. For example, the Moscow region is completely covered by this range by the operators MTS and Megafon, Beeline is a little behind, but work is also underway. The main thing is to raise the antenna higher to catch this range.
6. Band 20 (800 MHz). Its main task is to cover areas with low subscriber density. Due to its low frequency, the range of the operator’s base station reaches up to 20 km. Although this is a 4th generation network, the speed will, as a rule, be no more than 5 Mbit/s due to its narrow spectrum of 7.5 MHz.
7. Recently, the SCRF allowed operators to use 4G in the 2100 band. But I don’t think this will start happening before 2019.

In the previous article we already looked at third generation standards under the general name . However, communications of the fourth generation - 4G - are spreading rapidly. The main standard in 4G at the moment is LTE. Strictly speaking, LTE was not the first fourth-generation standard; the first widespread one was the WiMAX standard. Yota worked there for the first time, and some operators still use WiMAX. The maximum WiMAX speed is 40 Mbit/s, but real figures range from 10 to 20 Mbit/s.

But let's return to LTE. It is now the most widespread in the world in general and in Russia in particular. But what is 4G LTE? LTE (from English) Long-Term Evolution) is a standard for wireless high-speed data transmission for mobile devices. It is based on the same GSM/UMTS protocols, but theoretical and real data transfer speeds in LTE networks are much higher, sometimes even superior to wired connections!

LTE FDD and LTE TDD: what are the differences?

The LTE standard comes in two types, the differences between which are quite significant. FDD- Frequency Division Duplex (frequency separation of incoming and outgoing channels)
TDD- Time Division Duplex (time separation of incoming and outgoing channels). Roughly speaking, FDD is parallel LTE and TDD is serial LTE. For example, with a channel width of 20 MHz in FDD LTE, part of the range (15 MHz) is given for download, and part (5 MHz) for upload. Thus, the channels do not overlap in frequencies, which allows you to work simultaneously and stably for loading and unloading data. In TDD LTE, the same 20 MHz channel is completely given over to both downloading and uploading, and the data is transmitted to both sides alternately, with downloading still having priority. In general, FDD LTE is preferable because it works faster and more stable.

LTE frequencies

LTE networks (FDD and TDD) operate on different frequencies in different countries. In many countries, several frequency ranges are used at once. It is worth noting that not all equipment can work on different “bands”, i.e. frequency ranges. FDD ranges are numbered from 1 to 31, TDD ranges from 33 to 44. There are additionally several standards that have not yet been assigned numbers. Specifications for frequency bands are called bands (BAND). In Russia and Europe, band 7, band 20, band 3 and band 38 are mainly used.

Here is a list of frequency ranges of 4G LTE networks in Russia of the Big Five operators. There are also regional 4G LTE networks of local operators operating in other frequency bands, but their consideration is not necessary within the scope of this article.

The most important criterion, which is of particular interest to subscribers, i.e. users of 4G LTE networks, is the data transfer speed. And the speed primarily depends on the width of the frequency range of a particular operator, as well as the type of duplex used in the network. For example, for a 10 MHz channel, the 4G LTE speed will be 75 Mbit/s. It is with this nominal speed that the LTE FDD (band 7) networks of Tele2, MTS and operators operate. What about Megafon? And Megafon can afford more. Because several years ago there was a merger, or rather the absorption of Yota by Megafon, now Megafon has licenses for Yota frequencies, respectively, the maximum channel width can reach 40 MHz in the frequency range of 2600 MHz (band 7), which in theory gives as much as 300 Mbit/s! But basically the Megafon 4G network operates in a 15-20 MHz channel, which gives a download speed of 100-150 Mbit/s. After all, something must be left for Iota.

LTE-Advanced, or 4G+

The next stage in the development of 4G LTE networks is the LTE-A (LTE-Advanced) standard. Some operators call this technology 4G+ for marketing purposes, but this is completely incorrect. Those. in fact, it is LTE-Advanced that is truly 4G. Data transfer speeds in the LTE-A network are significantly higher than conventional LTE. The main feature of LTE-Advanced is the aggregation of frequency ranges. A subscriber device with LTE-A support summarizes data transmission channels in different frequency ranges available to the operator. For example, combining several frequency ranges in the 2600 MHz band, a channel of 40 MHz is obtained, which gives a speed in the LTE-Advanced network of 300 Mbit/s. But this is far from the limit. If you add another 20 MHz from the 1800 MHz band, you get a 60 MHz channel (band 7 + band 3), and that’s already 450 Mbit/s! However, these are theoretical or bench speeds. In reality, they are of course much smaller, but nevertheless, LTE-Advanced wireless technology is quite close to wired speeds.

It is worth noting that all operators can aggregate different channels in different frequency ranges if they have the appropriate licenses and network infrastructure. The main task is to expand the frequency range. The wider it is, the higher the maximum speed, i.e. network bandwidth. But of course there must be subscriber equipment that supports LTE-Advanced.

Prospects for 4G LTE

Despite the fact that the 4G LTE standard appeared several years ago, many regions of our country still do not even have 3G networks. So there is still room to grow. The world is already testing 5th generation (5G) networks, but in real conditions 4G LTE networks will dominate for a long time, fortunately operators are actively developing them.

In many cases, 4G Internet is not only an alternative to a wired connection, but also the only option, including an economically feasible one. Remote objects, the laying of wires to which involves certain difficulties or risks, and sometimes is completely impossible, also need to be connected. It is often possible to connect to 4G Internet even where there is no LTE network coverage. For this purpose special , which catch and amplify the 4G LTE signal. To choose the right antenna, you need to know which operator’s network you need to catch, at what frequency it operates, and also in what duplex mode (FDD or TDD). Our They will determine the type of signal, measure its parameters, and select the appropriate equipment to ensure fast and stable access to the Internet via the 4G LTE network.

Suddenly I had to delve into technical details that I would prefer not to know, so as not to bother myself with unnecessary details. However, in these difficult times, the desire to save money forces us to pay more attention to various technical specifications and so on.

During the Chinese sale, I ordered myself a beautiful ZTE Nubia Z9 mini smartphone at a low price. I actually have only two complaints about the available Beeline Pro - the quality of the photos and the size of the memory available for installing programs.

After some time, I received a parcel with Nubia, was glad about the camera and the fact that all 16 gigabytes of built-in memory were available for installation, and were not divided into two parts, and began to use it. A day later I noticed that the mobile Internet was clearly working worse than on its predecessor. Before ordering, I was already aware of the differences between FDD-LTE and TDD-LTE, that only FDD is suitable for Russia, and that’s what I ordered, and that’s exactly what I received - “with worldwide/international support for LTE networks.” Nevertheless, the picture compared to Beeline Pro was sad. The picture shows that Beeline Pro works great with 4G/LTE, and Nubia has generally switched to 3G/HSPA (clickable if anything)

At first I thought about the settings. Selected “preferred network”, etc. - did not help. But I found several more messages that the Z9 mini received the LTE signal worse than the other device and realized that the problem was not with my device and this was not a defect.

Then I began to understand LTE and read that the standard is not only of two types with time division (TDD) and frequency division (FDD), but also different frequencies (800, 850, 1800, 2100, 2300, 2600MHz, etc.) and these ranges are numbered 1, 2, 3, etc. The specifications indicate something like “Data transmission FDD LTE (Cat4, up to 150 Mbit/s) 1800/2100/2600 MHz” or “FDD LTE: bands B1, B3, B7”. I compared it with the bands supported by operators in Russia and it turned out that in our country the bands mainly used are B3, B7, B20. Moreover, my Beeline operator uses B7 (2500-2600MHz) and B20 (800MHz). A high frequency allows you to increase the transmission speed, and a lower frequency provides greater coverage with one base station, so, of course, we have more 800MHz towers. But Nubia does not support this range and can only use the 2500-2600MHz band, and coverage with this frequency in Moscow is small. So, unfortunately, this device is not very suitable for Beeline. But Tele2 subscribers, in theory, should not experience any problems - Tele2 in Moscow only has 2600MHz (it seems).

The Qualcomm chipset on which Nubia is built has the ability to use a special engineering program to unlock any frequency range in the modem. Which I did immediately. Unfortunately this did not give anything. Having rummaged around on the xda-developers forum, where we found quite a lot of upset French, Germans and English who generally have all LTE in many places only on the 20th band, I found out that unlocking band support with a modem will not do the trick - the radio module/antenna also needs to be designed to support the B20 band.

I had to part with my phone. Fortunately, there were a lot of people who wanted to buy it at the sale price - I sold it in 1.5 hours.

Along the way, I found out that many Chinese smartphones (Redmi Note2 FDD for example) with “international LTE support” do not support the 20th 800MHz band, only the same 1st, 3rd and 7th.

Now I know what to look for in the specifications. :(
