Internet and GPS Access with Modem Sierra 881u

In this article I will discuss my neighbor Sierra 881u modem device, whatever strengths and weaknesses. Hopefully this article can be a reference for those of you who want to buy the 3G modem.

Back when I bought this modem price is still about $100, but listen to hear the price down now to around $90-80.

Sierra 881u modem uses a USB interface that can plugged on your PC or laptop (and don't plug in nose, especially in your ass..ha..ha...)

For a USB modem, Sierra 881u includes a large size. This may be because the modem have not the facilities in other 3G modem, the facility GPS (Global Positioning System).

With GPS you can find out where you are now on the map and determine where you want to go with the help of satellites. This is possible because the modem is embedded a GPS chip.

From my experience even used this modem day stay cool, aka not hot, when you use a different mobile phones / 3G mobile phone as a modem. Mobile you will quickly heat and age-life was shorter.

Here are the advantages and disadvantages Sierra 881u modem :

Excess Sierra 881u modem

1. support 7.2 Mbps HSUPA (4G)
2. there GPS facility
3. cold, not heat quickly
4. can add an external antenna to strengthen the signal

Lack of Sierra 881u modem

1. rather large size
2. USB plug folding model, risk of fracture. use a USB docking solution.
3. use the additional battery (which is the excess or lack of it?)

Sierra 881u modem is HSUPA network support 7.2 Mbps downlink and 2Mbps uplink. But at first I bought was still wearing the setting HSDPA 3.6 Mbps.

To change to the 7.2 Mbps HSUPA mode, you need to give AT command (AT command) to the modem. Here are step step.

Enabling mode at 7.2 Mbps HSUPA Modem Sierra 881u

First you must know the port number sierra modem AT commands on your computer (may differ different case). The following way :

1. right-click on My Computer icon and select Properties
2. click the Hardware tab
3. click the Device Manager button
4. click the Ports (COM & LPT)
5. search the Sierra Wireless AT Command Port (UMTS)
6. note how his COM number, for example COM15, COM18, etc

After that do the AT (AT command) to your modem sierra, the following steps steps :

1. run the HyperTerminal program in windows by clicking the Start button> Accessories> Communications> HyperTerminal.
2. on the Connection Description dialog, fill in name (any) and click OK
3. the Connect To dialog, see the Connect using, select the port number that you noted earlier, click OK
4. typing AT! HSDCAT = 8 and then hit enter, it will display the message OK
5. typing AT! HSUCAT = 5 and hit enter, it will display the message OK
6. restart modem
7. done, now your modem speed 7.2 Mbps

Activating the GPS feature on Sierra 881u modem

1. download the firmware for the modem sierra here
2. SIM card out of the modem
3. firmware update by running the setup to complete. firmware updates can not fail because of dead lights for example, because it could be fatal for the modem hardware. so make sure you do not power off (use a UPS or a laptop)
4. 3G Watcher software download new here
5. do 3G Watcher software update MP by running the setup to complete
6. modem ready for GPS

To open the GPS menu, run the MP 3G Watcher software and click the Tools menu> Display of GPS. It looks like.
Keep in mind for the GPS with Sierra 881u modem is no SIM card need alias don't need pulse, you need a signal from the satellite over there.

To display the map you can use additional software such as the software that has been equipped garmin maps of course your country.

Tips n Trick Accelerating hp smart modems Haier D1200P

( "Horeeee .... Fun to the package from the Smart modem and free internet for 3 months", so about the joy when the first picture to buy this internet modem package from Smart services. Tetapinya ya But there, perhaps because there is a connection that's free rather a little slow. But do not fret old, below is the trick and tipsnya koq, let's be listened to. ") => authors joy
Before trying Tips2 below I suggest you to system restore point before your windows. Do I click start menu> all programs> Accessories> System Tools> System Restore> trus choose "Create a restore point. Ntar klo changes in your windows system problems can be returned to the system before it was changed. Please try tipsnya ...

1. The first Windows OS to talk the problem must first diakalin soale Windows using 20% of our bandwidth. So how much faster this way:

* Click the Start menu> run and type gpedit.msc
* In the computer configuration> administrative templates> select Network.
* In the QoS packet scheduler> Double Click on Limit Reservable Bandwidth.
* Click the Enabled Reservable bandwidth and fox settingannya to 0 (zero)% and then Apply and OK.

2. Click start menu> run and type regedit. In the HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Servic es \ TCPIP \ Parameters. The contents of this registry value:

* DefaultTTL content value 00000040
* EnablePMTUBHDetect content value 00000000
* EnablePMTUDiscovery content value 00000001
* GlobalMaxTcpWindowSize content value 0005ae4c
* SackOpts content value 00000001
* Tcp1323Opts content value 00,000,003
* TcpWindowSize content value 0005ae4c
* Restart your computer.

When the registry was not in the above parameters, can be added in a way, right-click New, then select DWORD, type the parameters above and fill valuenya.

3. If you can use Mozzila Firefox browser that've known Browsers Most Powerful and Safe ... download here http://en-us.www.mozilla.com/en-US/ and also setting Mozzila fox so much faster when browsing ... .. how :

* Open Firefox.
* Select the address bar type about: config and hit enter. If the exit warning click ok.
* Right-click in Firefox (under Preference Name) and select New and then Integer.
* In the New dialog box integer value - Enter the preference name with nglayout.initialpaint.delay content. Then when another dialog box appears content value / value to 0 (zero).
* In the Filter Bar (Filter:) is located under the tab opened type pipelining reply.
* Click two times (double click) on the written order settingannya network.http.pipelining changed to true.
* Then double click (double click) on the network.http.pipelining.maxrequests after leaving the contents of the dialogue box with a number between 10 to 30. The contents of 30 to get more leverage.
* Restart Firefox.

4. Use the pan Kilik:) See / Click HERE or the like to improve your modem signal.

5. There's also a smart modem users who approach it with HP Smart Antenna TV UHF TV lit conditions or Teflon coated with aluminum foil ... almost as rich pan Kilik this difference is coated with aluminum foil.

6. Smart Connections setting is not only using the username and password: smart dial up to * 777 but could also use:
user and password: wap - dial-up: 222
user and password: cdma - dial up: * 777 #
can also dial up to: * 99 # or * 31 * 11,111 #
aja try which dikombinasiin faster between the user / password with the dial-up which could also aja ko

7. For use AMD processors and failed to connect. You can use the driver version 1.3.13 Haier at their website directly smart http://www.smart.co.id/ aja open there.

8. Use as Cfosspeed Internet Accelerator, SpeedConnect, to use the browser to download FirefoxOptimizer and use Internet Download Manager (IDM) to increase the internet speed when browsing and downloading.

9. Recommended by Smart said when I disconect and will use the modem for the restart smart hpnya and pull the battery ... then plug it in again and make connections to the Internet. But I try to change the connection to the others turned out to be ko. Pake example of the smart user and password are connection 1 then move to 2 with user connection and other passwords tough .. no 6. So bikin aja 2 connection with a different user and password.

10. If you want to browse and download the current use smart modems night> 12 nights until the morning when traffic is not crowded smart.

11. Usually bad weather greatly affect the smart internet connection ... this one yet knows how to handle it ... wait for good weather or course;) wrote to complain ato cs smart.

12. If Automatic Updates to Windows and other program2 disabled it. Because it would interfere with our connection at the time the program runs automatic update feature. But everything has a risk. Yg antivirus user may want to antivirusnya regularly updated will be disturbed.

Bandwidth Optimization Model

Bandwidth usage in an institution is an ideal that can be achieved with many methods of approach. One is the modeling technique (Lakshminarayanan et al, 2004). Bandwidth usage can be distinguished on the basis of objective utilisasinya: web-session and streaming-session.

In opening a web page, the bandwidth will be used to download pages and files related, such as graphics (in various formats: GIF, JPEG, PNG, SWF), style and formatting (CSS), data (XML), and even streaming (FLV, MOV, AVI) short run automatically. The nature of the data tape utilization is sesional, or opened by the session.

For example, in the configuration of the browser (Mozilla Firefox: about: config, network.http.max-connections; about: config, network.http.max-connections-per-server) is set to a server that can only have a maximum of 8 connections, whereas total downloaded files in a web page is 32. There will be 32 sessions, with a maximum of 8 sessions running concurrently. This is a simplification (the actual principle is divided into data packets per session) to facilitate the representation that are said to be open sesional website. Examples of the characteristics of bandwidth to open a web page can be seen in Figure 1.

RealNetwork (2000) provides information on the characteristics of the streaming bandwidth utilization. Schubert et al (2008) mentions, the main challenge in doing the optimization of bandwidth for streaming purposes are to distribute streams (data streams) with high bit-rate without halting. Examples of characteristics to open stream bandwidth can be seen in Figure 1.
Figure 1. Characteristics of the HSDPA bandwidth usage Telkomsel (maximum speed of 480 Kbps) for a single user web-session (opened with Mozilla Firefox in rotation: http://www.google.com, http://research.microsoft.com/en-us/ people/padmanab/msr-tr-2004-44.pdf, http://www.youtube.com) streaming-session (opened with Mozilla Firefox: http://www.youtube.com/watch?v=qZe5D3MSjOI&feature=dir ). Bandwidth utilization observed in% in speed computer-modem connection is 10 Mbps.

Biogeographic

1. Based on the number of Users

The use of bandwidth for multiple users in an institutional environment will be influenced by many factors: characteristics of the sites accessed, the number of users, the delay (pause) transmissions, and bandwidth available. These factors will be analyzed with the following assumptions:

1. Bandwidth optimization index is proportional to the total bandwidth available.
2. Bandwidth optimization index is inversely proportional to the number of users.
3. Bandwidth optimization index is inversely proportional to the transmission delay.
4. Bandwidth optimization index is inversely related characteristics.

From this assumption, then created the index logic optimization model of the data tape as follows:

Description:
Optimation Index = number optimization to be achieved (without units)
Bandwidth = total data bandwidth (Kbps)
User = number of users (PC connection)
Transmission delay = interval (ms delay)
Characteristic = index site characteristics (Kbps / ms delay)

2. Based on the number of requests / second

The use of bandwidth for multiple users in an institutional environment can also be approached by other factors, the number of data requests / second, not just the number of users. These factors will be analyzed with the following assumptions:

1. Bandwidth optimization index is proportional to the total bandwidth available.
2. Bandwidth optimization index is inversely proportional to the number of requests / second.
3. Bandwidth optimization index is inversely proportional to the transmission delay.
4. Bandwidth optimization index is inversely related characteristics.

From this assumption, then created the index logic optimization model of the data tape as follows:
Description:
Optimation Index = number optimization to be achieved (per s)
Bandwidth = total data bandwidth (Kbps)
Request = number of requests (per s)
Transmission delay = interval (ms delay)
Characteristic = index site characteristics (Kbps / ms delay)


Engineering Optimization

1. Index measures the characteristics of the site (Kbps / ms delay)

At its core is to find a minimum value for the two situations (a) a web-session (b) streaming-session is in the current conditions: minimum bandwidth, maximum delay.

2. Stress-test done at the level (amount) of a particular user

Allocate sufficient number of users. These parameters can be calculated based on the average number of users online simultaneously at peak conditions (peak load) at a measured location.

3. Stress-test done at the level of requests / second

Allocate sufficient number of requests. These parameters can be calculated based on the characteristics of users (one user opens the website and how many sessions) at a measured location.

4. Conduct stress-tests on the level of transmission delay

Getting the value of the transmission gap in peak condition at a measured location.

5. Calculating the index optimization

Optimization index is measured by equation (1) or (2). Further optimization index can be approximated by three methods: best-fit, average, minimum index.

* Best fit: index optimization, where one of the selected characteristics of bandwidth utilization priority (eg priority to open stream more than opening web page). Therefore, the results of analysis of variance (ANOVA) on the characteristics of bandwidth priority should utilitasi superior characteristics significantly from the other bandwidth utilization
* Average: index optimization explained that all the characteristics of bandwidth utilization score is not significantly different.
* The minimum index: index optimization explained that all the characteristics of bandwidth utilization in a state of minimum requirements (large data or delaynya)

READ send SMS and SMS with AT commands

I. SEND SMS with AT commands

Previous connect your PC ama HP / GSM modem, and hold pake HyperTerminal application we started writing it AT commands.

The logic is like this:

0. Previously a PC with a terminal make sure we (HP / GSM modem)'ve connected ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... .. AT

Try tanyain our terminal equipment (HP / GSM Modem, whether he support PDU mode (0) or SMS text mode (1) or both ... ... ... ... ... AT + CMGF =?

1. For example kalo our tool support SMS text mode, then I want ngajak HP / GSM modem operating in SMS text mode ... ... ... ... .. AT + CMGF = 1

2. Now, we write the new number and we will send messages to the Message Storage on the HP / GSM modem (SIM card) we ... ... ... ... ... ... ... ... ... AT + CMGW = "reply destination phone number" ... ... (Enter) ... YG WANT TO SENT A MESSAGE ... .. (Ctrl-Z to end the message) ... then came info index number where the message we were saved in message storage.

3. We send our message in message storage index was ... ... ... ... ... ... .... AT + CMSS = nomorindexpesankita

Done ... for example AT commands, and his response below:

AT
OK
AT + CMGF = 1
OK
AT + CMGW = "+85291234567"
> A simple demo of SMS text messaging.
+ CMGW: 1

OK
AT + CMSS = 1
+ CMSS: 20

OK

-------

Complete AT commands for Send SMS:
AT command Meaning
+ CMGS Send message
+ CMSS Send message from storage
+ CMGW Write message to memory (the destination number and the message will be sent)
+ CMGD Delete message
+ CMGC Send command
+ CMMS More messages to send

------

II. READ SMS AT Commands Pake

1. Invite HP / GSM modem we make SMS text mode ... ... ... ... ... .. AT + CMGF = 1

2. Read all messages in the Message Storage HP / GSM modem (SIM card) we .... AT + CMGL = "ALL"

Examples:

AT
OK
AT + CMGF = 1
OK
AT + CMGL = "ALL"
+ CMGL: 1, "REC READ", "+85291234567",, "06/11/11, 00:30:29 +32"
Hello, welcome to our SMS tutorial.
+ CMGL: 2, "REC READ", "+85291234567",, "06/11/11, 00:32:20 +32"
A simple demo of SMS text messaging.

OK

--

See there are 2 messages in the Message Storage GSM Modem (SIM).

- "REC READ" means the message is read uudah

- "+85291234567" Sender number

- "" 06/11/11, 00:32:20 +32 "... the message is received on Year 11 ... 2006/Bulan 11/Tanggal hour time 00:32:20 (GMT +32 / 4) which is GMT +8

- The contents of the message

-------------

* To find options in the Message field Message Reading Storage (+ CMGL) ... ... ... ... ... ... .. AT + CMGL =?

* Reading the SMS messages on a particular index in the Message Storage ... ... ... ... ... ... ... ... ... .. AT + CMGR = nomorindex

Example I want to read SMS messages in Index 15 Message Storage:

AT + CMGR = 15
+ CMGR: "STO SENT", "0411363xxxx",
TEST OK TONY

* Setting up a new SMS If there are incoming HP / GSM modem we were told doing ... ... ... ... ... ... ... ... ... ... ... .... AT + CMNI = ..., ...., ..., ..., ... .. (options suitable number untu AT commands manual HP / GSM modem that we pake)

We can ordered "every time there is an incoming SMS sent directly to your PC" or "every time a save incoming SMS in Message Storage aja then mberi-known PC

* SIM card Mencheck whether we've just entered the GSM Modem ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... .. AT + CPIN?

AT + CPIN?
+ CPIN: READY

-------------

AT Commands for Reading SMS:
AT command Meaning
+ CNMI New message Indications (Kalo is a new SMS entry will diapain?)
+ CMGL List messages (See LIST (L) SMS in Message Storage!)
+ CMGR Read messages (Read / READ (R) messages in the index ...)
+ CNMA New message Acknowledge

-------------

* + CNMI for my GSM Modem (Wavecom)

AT + CNMI = treatment code for a NOT search results (only support mode 2: stored in memory and sent to the PC later), treatment for SMS Check-in (default 1), treatment for Cell Broadcast Messages are entered (0: if CBM is entry NOT be forwarded, 1: first stored in the modem and the index memory location is sent to PC applications, 2: forwarded directly to the PC), SMS Status Report on the route or not (default 0: not sent, 1: sent, 2: stored and shipped ), buffer (default 0: the contents of buffers sent to the PC, 1: fill the buffer is removed)

AT + CNMI = 2, 1, 1, 2, 0

--------------

So now the question:

"What if I want to send SMS messages rather than with HyperTerminal but I woke Application pake Language Programming and the AT commands (so that its interface easier to use by common people and its features can macem2?"

Answer: we need to write the script to send AT commands sequence to HP / GSM modem we had with our Programming Languages
