...gateway, to function as a cellular modem. This task is too small for our in-house SW devs to be concerned with as they are busy developing the main software platform which sends messages to the modem. Primary development platform is Digi TransPort WR41, I have one here I can send to you. Final implementation would be run on a TransPort device which supports global cellular frequencies including CDMA while it lasts in the US. Solution should also be applicable to other TransPort devices in the same family. Must interface with Vaisala viewLinc continuous monitoring software, alarm notifications and acknowledgements are sent using AT Hayes modem commands to a PC serial port. The modem must utilize those commands to send and receive SMS only, no voice, no data. AT command functio...

We need a non-gui app that operates in two modes a) Continuous mode b) Remotely controlled mode The app should do the following in either of the above modes 1. Record phone screen continuously 2. Record all calls (both GSM/CDMA and VoIP, Whatsapp etc.) 3. Send locations 4. Record mic 5. Record cameras We know this can not probably be done through stock android ROMs so we have an option to do the same from a custom ROM. All the files that the app generates should be uploaded to Amazon S3 bucket (access will be provided). A short interview might be conducted before hiring for the job.

This is a duplicate of a project I saw on GetaFreelancer. I would like the same thing. I'm looking for a WordPress plug-in (ideal!) or PHP script that will take the 1003 form data like: on the front end of the script, and it to save data to a database on the server in Fannie Mae Version 3.2 format but also email me the data in that format after the loan application is completed. The front end would require the user to create a quick username and password so the person can save their progress during the application process because most people will not be ablt to complete the entire form in one visit, so progress must be saved. I would also need an admin section where we can add/remove/edit/export the loan app
We are looking for solution like a traditional GSM or CDMA VoiP gateway. This project will be separated in two parts. One is mobile application and another one is registration server. The Mobile application will register to a server and accept call from that server with IXA or SIP protocol. After that call will terminate to a GSM network. (this part just like a traditional GMS getaway) This mobile application will work on only wifi Internet connectivity, coz GSM internet data normally disable during any GSM call. All call will pass with G729 codec The registration server may be Asterisk or VOIP switch or any other server or customize server. This server will receive call from another VOIP switch server with SIP protocol. Certain number of registered Mobile will be able to ass...
We are looking for the person specialized in GSM CDMA LTE mobile enhancers / boosters. The perfect candidate working background should be in Mobile Providers company or related field which has ever dealt with antennas and signal boosters. The job is for customer support for signal boosters users by helping them to install product and make it work correctly. Only bidders who have relevant experience will be reviewed. You will be examined before hiring.
Due to slow acoustic propagation of acoustic waves the data rates in underwater acoustic communications that can be archived is relatively very low compared to RF channels in the air. In this work we will study through matlab simulations first then experimentally the performance of uniquely decodable ternary code sets for highly overloaded synchronous Code-Division Multiple Access(CDMA) systems in underwater acoustic scenarios. The underlying main challenge is to design and experiment advanced receivers that could potentially mitigate the high multipath and Doppler effect present in the underwater acoustic channels.
Due to the slow acoustic propagation of acoustic waves the data rates in underwater acoustic communications can be achieved is relatively very low compared to RF channels in the air. In this work we will study through Matlab simulations first and then experimentally the performance of uniquely decodable ternary code sets that can provide many more users then the conventional CDMA ternary codes sets. The main challenge of this project is to design and experiment advanced receivers that could potentially mitigate the high multipath and Doppler effect present in the underwater acoustic channels.

I bought a used SAMSUNG Galaxy Tab S 10.5 LTE US CDMA SPRINT tablet (SM-T807P). This device works in CDMA networks but I need it to work in GSM networks (GMS / HSDPA / LTE). I'm outside US. I have the MSL code and the device is already rooted (CF-Auto-Root), unlocked and debranded (idoneapps app). In addition with a custom recovery flashed (TWRP). After a few weeks of trying different configurations (ServiceMode), programs (CDMA Tools, Qualcomm Tools, DFS, etc) and patches (editing the , etc) all, basically, taken from the XDA site, I'm still not getting connection to any (2G/3G/4G) of my 3 local carrires.

...network problems and other related IT problems. WeCare often looks to experts for assistance. WeCare has recently hired you to help on a new project. Assume that you are requested to design a Medium Access Control protocol for a set of low power wireless (mobile) nodes that have to communicate with a wireless access point. Your constraints are: 1. You can only use FDMA and TDMA like schemes (CDMA is not considered for cost and complexity reasons). 2. The nodes clocks can drift in time by some maximum known value. 3. Nodes can have three modes: Transmit, Listening/Receiving, Sleep. While transmitting nodes consume twice in comparison to when they are receiving. In sleep mode nodes consume 1% power in comparison with transmit mode. Only the mobile nodes are power limite...
