The truth about Blackberry?

Question

blackberry

I have heard a lot about Blackberry, but could not get any clarity on the following issues:

1. I was told that the savings in email traffic through Blackberry is due to push email technology. Say, you are not hammering at the server, eating money, but it is hammering at you if a letter has arrived and only in this case. To me, that looks like bullshit. Indeed, in this case, there must be a permanent connection to the server via GPRS. And the exchange of traffic is still there. What happens to the battery in this case?
   
2. Is there any freebie when communicating with BES ? Maybe free traffic?
   
3. What does the phrase "with Blackberry coverage" mean?
   
4. I was told that, unlike the iphone, which ate $ 1500 in roaming to check mail, in Blackberry it is free or almost free. This is true?
   
5. Praised mail encryption when working with BES. Is it just the encryption of the smartphone <-> BES channel or something more?
   
6. Is traffic saving when working with BES achieved only through compression? (like opera mini for mail?)
   
7. Is there anything about Blackberry that other smartphones can't achieve?
   
8. Is it true that BES should be at the operator? Do our operators have BES?
   
9. Why is he so loved?
   

Answer 1

1. Yes, Push works when you register with the Blackberry Service and set up accordingly. Usually, the Blackberry Service agreement with the mobile operator includes a clause on free service traffic, including server scoring.
2. Usually a subscription fee is taken, and service traffic to it goes free of charge
3. Where local operators provide preferential access to Blackberry Services, including Push email, free traffic, notifications and other services. Those. the local network must negotiate with RIM.
4. In those countries where the Blackberry Service operates and, accordingly, in the networks of those operators where there is a partnership
5. Encryption of packet data (not voice) during transmission, works in conjunction with the Blackberry Service
6. I don’t know about compression, but the fact that there are no periodic checks (due to push) also affects. Perhaps the server optimizes messages for the device (squeezes pictures, cuts off unnecessary headers ...)
7. Working with blackberry service, very good build quality, comfortable keyboard, business recognition (not pop music), price level (unclench your hand - and everything is immediately clear )
8. That's right, to work with its services must. Beeline and MTS have.

Answer 2

I can only answer the first point. It's true. But only if you have an official service. This automatically means that you are constantly connected to the Internet. The battery holds 4-5 days, at ~ 15 min. calls and ~15 min. internet per day. I can add that the local browser is shit. And I look at sites with Opera Mini. Which after Opera Mobile is also not a gift. Phone Blackberry Bold 9700.

Answer 3

A bit of history, because then it is more difficult to explain. Since its inception (and this was in 2003, if my memory serves me right), Blackberry gave its users only two advantages, but competitors did not have these advantages at that time: (1) guaranteed message delivery time; (2) encryption of all traffic from the BES (which, according to the norms, should be inside the DMZ) to the subscriber device. At that time, no one did that. SMS could go for days (72 hours waiting at SMSC is the norm), mail - either pull every 5 minutes, or wait for the weather by the sea. Therefore, BB was the first to be appreciated by traders who need the speed of information transfer and its secrecy. Well, stock market players (especially the lucky ones) in America are at the level of Gods. And since they go with BB, this platform quickly became an image platform for corporate clients. Just looking at BB
Now, in order of the questions asked.
1. These are unrelated items. "The kitten is warm because it is fluffy." No kitten and warm and fluffy. You can, of course, say that PushMail saves traffic due to a constant connection to the service, but how do you yourself imagine a “permanent connection” on the Internet? Network static doesn't work. Nuzher HeartBit - constant test impulses. The MS, for example, simply sends an HTTP request to the ActiveSync server with a very long response time. If something appears on the server, it is immediately transferred to the device. If the waiting time ends, the device raises the next session. And so all the time. You can look at the details on the MS website in the description of the vSync protocol. I don’t know the details about BB, but it’s unlikely that there is something very different. And traffic is compressed using a simple ZIP algorithm, there is nothing original here either. Another question,
2. As already mentioned above - if the BB has an agreement with the operator. Often this results in the fact that under the BB you need a separate tariff, to which you can only connect “when buying a device from an operator” ... I don’t know, you need to check with your OPSOS.
3. I think the same as in paragraph 2
4. Roaming is the golden cow of all operators. Check this question with the operator ten times. Only if the BB pays both one and the other OPSOS, then traffic will be free for you in roaming.
5. Yes, this is exactly “vaunted encryption” in the best sense of the word. Pretty crypto-resistant supposedly proprietary encryption algorithms BES <-> Smartphone. That is why our special services did not certify this system for so long, and certified it in a very "castrated" version - when the BES is at the operator, and between the operator and the client's mailer - at least the wind is whistling (well, it's like, the client himself should take care, but, again -All within the protocols and systems permitted by our special services).
6. Already almost answered above. Of course, there is compression, but on top of it there is encryption, which, if not a lot, adds traffic.
7. In relation to Russian realities, only “here, this is such a phone that no one else has!” In America, this is the most corporate standard of all corporate standards. And here MTS is trying to sell it to ordinary users. The phone is the phone. Operating system - its own, applications - a very limited list. It seems that there are no problems with Russian anymore, but ... There are a lot of BlackBerry-Style devices from all manufacturers - from Nokia to HTC. PushMail on ActiveSync Server (Exchange) presses traffic in the same way, can load headers, not whole letters, in the latest editions of WinMo 6.x it was already very, very economical to eat a battery, etc.
8. No, not true. As I said above, BES should be inside the DMZ, directly attached to the mailer (Exchange, Lotus, etc.). The current Russian implementation, when BES is at the operator's place, is a laughing matter, or rather, "big brother said to do it."
9. For what he is loved in the USA, I wrote. I can say why our corporations do not favor him so much. (a) BES stands at the OPSOS, you somehow have to reach for it, gimorroitsya. (b) All traffic from BES does not go directly to the OPSS, but is downloaded through the central BB servers in the USA. And which of our “oil workers” (for example) will want to download their traffic through the USA, especially since the protocol is proprietary, and no one knows its details, except for the BB. "But what if?" (there was still (c), but I forgot ... I remember - I'll write)

Answer 4

The most important thing is that RIM agreed with the FSB;)

Answer 5

And I'm more interested in the question - what for this Blackberry is needed ?!

Answer 6

1. BIS is not available in my area, so I use the free Shangmail service for push mail. There are no disadvantages compared to a full-fledged BIS - only a delay in receiving letters for 1-5 minutes. By billing: in the Beeline detail, only the moments of receiving / sending letters are noted - i.e. interval write-offs do not occur. The battery requires recharging every 4 days.
2. I can’t say anything about BES - probably, it depends on the agreement between the BES owner and the operator. By BIS - a subscription fee usually includes unlimited mail and IM.
9. Why is he so loved?
Already the third BB and competitors are not nice to me. Ultimate intuition, I guess. And both software and hardware.
I have hooked more than one person on this wonderful device.

Answer 7

To use all the advantages of BB, do I need to be connected to the paid BES service from the provider?

Answer 8

in the case of BB synchronization with mail, we are talking about a protocol with an implementation of something like IMAP idle
