Module : Understanding the Ebola Virus and How You Can Avoid It
INTRUDUCTION
There has been an outbreak of the Ebola virus in West Africa. Guidelines have been issued by a number of public health Agencies Worldwide to assist in halting the spread of this deadly disease. This free lesson summarizes the health guidelines issued and will help you Understand the background of this disease, its symptoms, and how the medical profession Is dealing with treatment.File:The virus I hope this short, free lesson on Ebola virus will assist education among those who are at risk From the disease and increase awareness of its treatment, and also increase understanding with regards to the limit of its danger to public Health.
THE YATEBTS TECHNOLOGY COMING SOON IN CAMEROON
What is YateBTS
YateBTS is an open source GSM Base Station software.
You can use this software to create a 2G GSM network, either standalone or connected to the public telephony network.
The use of a non-DSP aproach for GSM protocol together with a SIP implementation that supports an IMS core and SS7 core network makes it a disruptive technology.
Please see the INSTALL file for information of how to download, build and install YateBTS.
Configuration
YateBTS is a module for the Yate telephony engine.
You will need to configure Yate to load it and also YateBTS itself.
YateBTS
The module is configured by the ybts.conf file. Depending on the install method you may have just an ybts.conf.sample which you will need to copy as ybts.conf
As a minimum you will need to configure the radio band and frequency (ARFCN) on which YateBTS will operate. Please read the minimal instructions at top of ybts.conf.sample
Depending on the transceiver you will need to edit the path setting in ybts.conf:
[transceiver] Path=./transceiver
replace ./transceiver with ./transceiver-rad1 or ./transceiver-uhd or ./transceiver-usrp1
Alternatively you may create a symbolic link to the desired transceiver:
cd /usr/lib64/yate/bts (or wherever it is installed) ln -s transceiver-rad1 transceiver
Network In a Box
The Network In a Box (NIB) is a configuration that allows using YateBTS standalone with just local subscribers.
To use it you need to configure in Yate:
In file javascript.conf:
[general] routing=welcome.js
[scripts] nib=nib.js
In file extmodule.conf:
[scripts] gsm_auth.sh
For more info see: http://wiki.yatebts.com/index.php/Javascript_NIB
Cellphone Network Brings Coverage Almost Anywhere
OpenBTS and YateBTS help communities replace expensive cellular network infrastructure with open source software. Image: mayo5/Getty Antarctica is probably the last place you’d expect cellphone service. But thanks to the Australian government and a company called Range Networks, you’ll soon be able to find a signal near several research facilities on the continent. Range has already brought GSM service–the same type of network that carries voice calls and text messages elsewhere in the world–to Macquarie Island, a small island just outside the Antarctic Circle. This is preferable to walkie talkies or Wi-Fi because it provides wider coverage while using less energy. And although the network has a satellite uplink to connect it with the rest of the world, it doesn’t depend on satellites for local communications, which is essential to the safety of field researchers.
