How much time does a single transmission take?

Hello,
I was wondering what is the time taken to transmit one sample takes. For example, if the sample interval is 5 seconds, does the actual transmission take 10ms? What does it do for the rest of the time?
Also, how much energy does a 3202 node take to transmit a single sample?
Thanks,
Sravan

Hey Sravan,
I wanted to provide some additional details to Kyle's post above.
This is on average what we have seen with a 3212 node sampling at a 60 second sample interval:
Sleep Duration: 58.774 seconds
Sleep Power: 7.41 mJ
Acquisition Duration (All 4 channels): 1150 ms
Acquisition Energy: 2.84 mJ
Transmit Duration: 55 ms
Transmit Energy: 9.17 mJ
Receive Duration: 21 ms
Receive Energy: 1.83 mJ
Additionally, if your sample rate is above 61 seconds, then you will run into the Heartbeat Interval which fires after every 61 seconds of inactivity. Below are average power measurements for the heartbeat interval:
Transmit Heartbeat Duration: 55ms
Transmit Heartbeat Energy: 7.79 mJ
Note: Each heartbeat will then also need to account for receiving that a response from the gateway (Receive information from above).
Taking all that into account, the graph below shows estimated battery life for sample intervals up to 300 seconds. The dips in the graph represent a sample interval that is just larger than the heartbeat interval, which essentially means you are transmitting twice in a very short period.
Hopefully you find this information helpful. Please let me know if I can clarify anything for you.

How much time does the ESS import take?

Hi,
How much time does import of ESS into NWDI take?
I have selected following files for import yesterday:
SAP-JEE
SAP-BUILDT
SAP-ESS
SAP-JTECHS
SAPPCUI_GP
and looked at it today and it is still importing.
In CMS Transport Studio State column displays message: Import running.
Any ideas why it takes so long?
Regards,
Ladislav

Hi,
I have imported files one by one in this order:
SAP-JEE
SAP_BUILDT
SAP_JTECHS
SAPPCUI_GP
SAP_ESS
Is this order correct?
I didn't import EP_BUILDT - is it required?
I have checked the CBS logs and there is one broken DC in SAPPCUI_GP compartment
in the pcui_gp/isr development component.
The build log contains this error:

1g tc: How much time does a firmware update take?

Concerning firmware update on a 1st Generation Time Capsule.
This Time Capsule is in use solely as a backup device for iMac
(1) Is 6+ hours for a firmware update usual?
At 8am this morning, "Airport Utility found a Time Capsule 802.11n (1st Generation) that is reporting problems."
Clicked: continue
alert: "This Time Capsule should be updated to a newer firmware version.
Current Version: 7:4:2
New Version: 7.6.4
progresion bar (continues to sprial)
Searching for latest firmware version... "
(2) (now 2:00 pm and ... has the application crashed?
checked "Force Quit" Airport Utility doesn't say "not responding" although the icon seems to be dimmer than others.
(3) Since Airport Utilities show a "Searching for...." message, can I quit the update process at this point without damage?

The update takes 2-3min max..
Unfortunately if it is dead well it is long dead.. if you stop the update now and reboot the device and see if it still works.. it sounds to me like it didn't start.
If it is dead well it is long overdue to be dead. Most of them died before 2years ran out.

How much space does a new app take?

My 16GB Touch is pretty full (about 360MB left after all the music is loaded). How much space does the typical app take up?

There are some that are larger (Super Monkey Ball supposedly takes up 36 MB), but most that I have seen or downloaded are around 1 MB. SUPER small

How much time does an AP take to failover to secondary controller

hi All,
My query is to understand how much time will an AP take to failover to its secondary WLC(Backup) incase primary goes offline.
Whats the heartbeat time for each AP to verify reachability to WLC.
also what is the purpose of AP Fail over priority under each AP. i want to ensure AP's fall back to primary WLC once its back online.(Preemption)

Hi Matehw,
My query is to understand how much time will an AP take to failover to its secondary WLC(Backup) incase primary goes offline.
We can not tell exact time but normally It takes 1-3 minutes.
Whats the heartbeat time for each AP to verify reachability to WLC.
AP Heartbeat Timeout - AP sends heartbeat to WLC (By default its 30s). Once the primary WLC(or where AP is connected to)goes down, With heartbeats, the AP realizes sooner that the controller has become unreachable.
also what is the purpose of AP Fail over priority under each AP.
First of all there are three types: it goes like this Cirtical...high...medium..low.
***To configure AP failover priority, we must enable AP Fallback feature globally and then individual APs with a suitable priority level.
*** When using both the local and global backup configurations, the locally configured settings take precedence in the event of a controller failure. If an AP is not able to join any of the locally configured controllers, it then tries to join the global backup controllers.

How much time does it take to build a website in muse?

I would like to know how much time I will have to use in order to make my website from scratch.
I already have the content (Images, Text, Organization)
I would like it to be 10 pages.
I have watched a lot of tutorials and have played with muse for a while.

Hi
This would entirely depend on the site and the design you are creating.
There is no exact time defined as such , as you have already gone through tutorials and worked with Muse , I would suggest you to use the features and try.
Thanks,

How much time does 8.2 software have?

I've been reviewing software revisions for the Cisco ASA 5500 family. We have a few clients running 8.2 and the jump to 8.3 will require significant effort to make sure everything translates properly. There are no features in 8.3 that these clients require so it seems in their, and our, best interest to let them ride the 8.2 software until an upgrade is necessary to continue receiving security patches. I have looked for EOL notifications but have not found anything for 8.2. I have also placed an inquiry with our SE at Cisco, but I thought I would ask if anyone knows anything about how much time 8.2 has before we could expect to see an EOL notification.

Hi,

I can't seem to find the same for the 8.2.
Though I would consider that there are still alot of users happily going about with the very old PIX firewalls running software 6.x or even older. Not saying its a good thing but it work.
And considering 8.2 is the latest software before the BIG NAT change I would imagine it will stay in use for a long time for those that dont want to learn/adopt the new NAT format.

How much time does CATPATCH.sql take

Hi,
Iam upgrading my db from 9.2.0.1 to 9.2.0.4 . Its been 2 hrs since the catpatch.sql script is runnig. When i queried dba_registry it is showing status as loading for packege & body.
Can any tell me how much does this script takes.
Thanks in advance.
Bhavesh

The speed of execution is very dependent on the memory and CPU of the machine in which the patch is being applied. I have seen times ranging from 30 minutes to 4 hours. The four hours was experienced with a database in a virtual machine with 512MB of RAM.

How much RAM does the iPad OS take up

If I buy an iPad, how much RAM is used by the OS, or how much RAM do I have to use?

Are you actually asking about RAM, or do you actually mean "storage capacity"?
Do you actually want to know how much free space a 16GB or 32GB iPad has "out-of-the-box"?

How much time does it take to launch iMovie on Macbook pro retina ?

On my system ,it takes some 4-5 s,should not it be faster due to ssd?iPhoto opens in one -two seconds,however.

I've been downloading a rented movie from iTunes on my iPad or several hours now and barely a quarter done. What am I doing wrong?
Impossible to say. A transfer takes as long as it takes. And since you are giving us no concrete information to go on, all we can do is make guesses. For instance, you list a PB G4 platform and OS X v 10.6.3. Should I assume you are performing the transfer on an old 400 MHz PB or a newer Intel Duo PBP 2.67 GHZ platform. Are you using an old 1.1 USB connection or USB 2.0? is this a direct download from iTunes via a wireless connection and if so is it running in "a", "b" or "n" mode? Should I assume that Time Machine is making hourly backups and is interferring with normal transfer operations or not? How may other processes and/or applications should be assumed to be in operation. Should we assume the rental is in an SD or HD format?
Basically, you hardware/software combination may or may not be performing normally. But it is impossible to say whithout knowing more about what (in terms of data size) is being moved and how you are moving it.
