Tutorials / Open BTS Installation

(bp432) — Sat, 19 Jan 2013 23:15:28 GMT

ITP is running OpenBTS 2.8 on Ubuntu 11.04 with a USRP2 Software Radio from Ettus Research with an RFX900 Daughterboard. What is OpenBTS? OpenBTS is a Unix application that uses a software radio to present a GSM air interface to standard 2G GSM handset and uses a SIP softswitch or PBX program to connect calls. The combination of the global-standard GSM air interface with low-cost VoIP backhaul forms the basis of a new type of cellular network that can be deployed and operated at substantially lower cost than existing technologies in many applications, including rural cellular deployments and private cellular networks in remote areas. http://en.wikipedia.org/wiki/OpenBTS What makes up the OpenBTS System? SOFTWARE: Ubuntu 12.04LS clean install. Prerequisites and basic updates suggested after a new Ubuntu install. GNU Radio and UHD drivers which are the software radio components that allow control and modulation over the USRP Radio. They also have prerequisite libraries to install. OpenBTS itself. Currently version 2.8 Opelousas. This is the GSM implementation and the main SIP interface which is normally on port 5062. Transceiver. This is the software radio-modem which is started by OpenBTS automatically. A SIP PBX or softswitch (Asterisk, FreeSwitch, etc.). This component connects speech calls. Its SIP interface is normally on port 5060. This is not packaged with OpenBTS and needs to be installed separately and following a non-standard procedure mentioned in this guide. Note that, if using Asterisk as in this guide, Asterisk will need the ODBC module installed and supporting libraries for proper configuration because it needs to communicate in realtime with the databases that store the phone and IMSI numbers. An IMSI numbe ...

Tutorials / GSM Notes

(bp432) — Fri, 18 Jan 2013 22:34:22 GMT

Quick overview of GSM Networks The GSM system is comprised of a a chain of technologies that are linked to encode receive and route your data from your handset or mobile device to an end destination. The flow of the system is as follows starting from your GSM capable handset or MS Mobile Station. Overview of BTS System and its components MS (Mobile Station): SIM (Subscriber Identity Module) holds an IMSI (International Mobile Subscriber Identity) number. ME (Mobile Equipment/terminal) BSS (Base Station Subsystem): BTS (Base Transceiver Station) BSC (Base Station Controller) NSS (Network Switching Subsystem): MSC (Mobile Switching Center) performs the switching functions and connection to other networks. GMSC (Gateway Mobile Switching Center) gateway that connects the cellular network and the PSTN. HLR (Home Location Register) The HLR stores information of the subscribers (such as services) in the coverage area of a given MSC. The MSC (Mobile Switching Center) connects to: |----- SGSN (Serving GPRS Support Node), which routes data to and from users’ MEs. --- GGSN (Gateway GPRS Support Node), which links mobile networks to external networks such as the internet. |----- GMSC (Gateway Mobile Switching Center), which links the mobile network to other phone networks and handles roaming. --- PSTN (Public Switched Telephone Network) or regular ol’ phone lines. --- ISDN (Integrated Services Digital Network) such as new digital phone lines. |----- SMSC (Short Message Service Center), which handles SMS. GPRS - General Packet Radio Service.SMS - Short Message Service. Typical Call Flow The ME is linked to a BTS via EM pulses. Once the ME's identity is verified via its International Mobile Subscriber Identity (IMSI) code and a channel is allocated, the transfer of data can ...

Labs / MIDI Output using an Arduino

(ndy204) — Wed, 12 Dec 2012 22:30:58 GMT

Overview This page covers only the details of MIDI communication on the Arduino module. For a more general introduction to MIDI on a microprocessor, see the MIDI notes on Tom's physical computing site. MIDI, the Musical Instrument Digital Interface, is a useful protocol for controlling synthesizers, sequencers, and other musical devices. MIDI devices are generally grouped in to two broad classes: controllers (i.e. devices that generate MIDI signals based on human actions) and synthesizers (including samplers, sequencers, and so forth). The latter take MIDI data in and make sound, light, or some other effect. Table of Contents (hide)1. Parts 1.

Intro / Topics

(dpr2) — Wed, 21 Nov 2012 19:08:45 GMT

Some time in weeks 1 - 3: Attend a tool safety session in the shop For each week, you'll find: Practice Topics we'll discuss in class. Course notes are linked so you can read them before class, to know what we're talking about. Lab assignments that illustrate the practice topics. You should read through the labs and try as much as you can the week before the lab is discussed in class. We'll go over the principles in the lab in class, so bring your hardware, and you'll get a chance to try it while we discuss, and ask questions. You'll be responsible to show at least one lab finished lab project in the first half of the semester in class. Your instructor will pick the next week's lab presenters at random each week. Production assignments larger assignments which have scheduled times you'll be expected to show them in class. Reading to be read in the week they're assigned. Will come up in discussion the week after, usually. Blog assignments Writing the week when it's assigned. Will come up in class from time to time. Read each other's stuff too. Come to class with questions prepared about that week's assignments. If you have no questions, be prepared to show a working version of what you made. Week 1 Practice Topics: What is physical interaction? Interaction concepts: discrete vs continuous, parallel events vs serial events, play testing, user observation. In-class exercise: As a class, we'll make a list of fantasy devices; things that don't exist, but that we wish did. For the moment, we'll ignore technical feasibility, and concentrate on how you'd operate these devices if they did exist. You'll be divided into groups of 3. Pick a fantasy device from the list. Design a control interface for this device and demonstrate it in-class. Think about what a person has to see, hear, touch, etc. while operating the device. Think about what cues they need to understand the interface. ...

Labs / Serial Duplex using an Arduino

(ndy204) — Mon, 01 Oct 2012 15:56:38 GMT

Overview In the first serial lab, you sent data from one sensor to a personal computer. In this lab, you'll send data from multiple sensors to a program on a personal computer. You'll use the data from the sensors to create a pointing-and-selecting device (i.e. a mouse). Table of Contents (hide)1. Parts2. Connect the sensors3. Read and send the serial data 2. Parts For this lab you'll need: Solderless breadboard 22-AWG hookup wire Arduino Microcontroller module accelerometer(or two other analog sensors) switch 3. Connect the sensors Connect two analog sensors to analog pins 0 and 1 like you did in the analog lab. Connect a switch to digital pin 2 like you did in the digital lab. The photos and schematic in this lab show an accelerometer and a pushbutton. You don't have to use these, though. Use whatever sensors are appropriate to your final application. While you're figuring what sensors to use, use the most convenient sensors you've got in hand; perhaps two potentiometers for the analog sensors and a pushbutton?

Labs / Serial Out using an Arduino

(ndy204) — Mon, 01 Oct 2012 15:53:39 GMT

Overview In this lab, you'll send data from a single sensor to a program on a personal computer. The program will graph the output of the sensor onscreen. This is a common way to find out how a sensor's output corresponds to the physical events that it senses. Table of Contents (hide)1. Parts2. Connect the sensor3. Read and send the serial data 5. Parts For this lab you'll need: 22-AWG hookup wire Arduino Microcontroller module 10Kohm potentiometer (or a different form of analog sensor) 6. Connect the sensor Connect your analog sensor to analog pin 0 like you did in the analog lab. A potentiometer is shown there because it's easy, but you might want to pick a sensor that's more interesting. IR distance rangers are fun for this exercise, for example. Force-sensing resistors are good as well. 7. Read and send the serial data Program the Arduino module to read the analog sensor and print the results to the Serial monitor. Instead of using Serial.println(), however, use Serial.write() to send the sensor value serially. void setup() { Serial.begin(9600); } void loop() { int analogValue = analogRead(A0) /4; // read the pot value Serial.write(analogValue); // print the value in the serial monitor as a binary value } [Get Code] document.write("What is the effect of dividing the sensor reading by 4?") You get a result that ranges from 0 to 255 instead of 0 to 1023. This means that the result will fit in a single byte. You'll see why that's convenient shortly. %lframe width=300 ...

Here are some of the components you'll use frequently when making electronic circuits. For more on any component, check out its datasheet. Table of Contents (hide)Voltage RegulatorLED Voltage Regulator 5V voltage regulator Voltage regulators take a range of DC voltage and convert it to a constant voltage. For example, this regulator, a 7805 regulator, takes a range of 8 - 15 volts DC input and converts it to a constant 5-volt output. Note the label on the regulator that reads "7805". Check the label on every component. This physical form factor, called the package, is used by many different components, and not all of them are voltage regulators. This is a TO-220 package. The 7800 series regulators come in many different voltages. 7805 is a 5-volt regulator. 7809 is a 9-volt regulator. 7812 is a 12-volt regulator. All the regulators of this family have the same pin connections. In the image above, the left leg is connected to the input voltage. The middle leg is connected to ground. The right leg is the output voltage. Link to 7805 datasheet 3.3V voltage regulator 3.3V regulators are also common. Note that these ones don't have the same pin configuration as the 7805 regulators! LED LEDs LEDs, or Light Emitting Diodes, are diodes that emit light when given the correct voltage. Like all diodes, they are polarized, meaning that they only operate when oriented correctly in the circuit. The anode of the LED connects to voltage, and the cathode connects to ground. The anode in the LEDs in this photo is the longer leg on each LED. LEDs come in many diferent packages. The packages above ...

Please be present and prompt. Lateness will hurt your grade. If you're going to be late or absent, please email your instructor in advance. If you have an emergency, please let your instructor know as soon as you can. Please turn in assignments on time as well. Laptops Laptop use is fine if you are using your laptop to present in class, or if we're in the middle of an exercise that makes use of it. Whenever classmates are presenting or we're in the midst of a class discussion, however, please keep your laptop closed. The quality of the class depends in large part on the quality of your attention and active participation, so please respect that and close your lid. Mobile Phones Please put them on vibrate or turn them off before you come to class unless they are part of your project. If you have an emergency that requires you to answer your phone during class, please tell your instructor ahead of time. Lab Assignments There is a lab activity for nearly every class in the first half of the semester. They are very short, simple activities. These are the basic steps you need to go through to understand the principle discussed in class each week. They're designed to help you not only to understand the technical details, but also to get a feel for what the technologies we're discussing can do, so that you can incorporate them into actual applications. You should at least complete the steps outlined in the lab activity each week, so that you understand practically what it is we're talking about. Document on your blog any discoveries you make, pitfalls you hit, and details not covered in the class or the lab that you think will be useful for your fellow students and future students ...
