Juniper QFX running on ESXi

Because of my day to day job I'm spinning around networking more and more. Which is not that bad if you ask me. Up until some time ago I was, and I think it's not only me, taking routing/switching for granted - yet another transport layer.
The more I'm getting into it.. it stays as boring as it always was. (joke, but it's boring)

No matter how your views on R/S are recently I found something worth sharing. To be honest, almost each day I'm seeing something from Juniper worth sharing, therefore there will be more resources/links posted here.

Now, in case you haven't noticed, Telecom market is turning towards virtualized solutions. Currently I'm a happy guy as I'm part of the Affirmed Networks, leader in virtaulizing telecoms.
This is also a reason more and more resources will be about boring IT, because virtualization is an IT thing for what 10-15 years by now probably, rather than virtual telecom.

Today I want to share post where David is showing how to run Juniper QFX on ESXi.
This might be useful if you dont have enough to spend on physical appliance of QFX to start fooling around.

Resource: SIM Card Forensics - Introduction

Just few moments ago I have found quite interesting article that covers in details how the SIM card is build and works. Maybe for Terminal-side guys this is obvious but myself I found few new things for myself.
As the title says this is just introduction, more information could be coming.

SIM Structure and File Systems

A SIM card contains a processor and operating system with between 16 and 256 KB of persistent, electronically erasable, programmable read-only memory (EEPROM). It also contains RAM (random access memory) and ROM (read-only memory). RAM controls the program execution flow and the ROM controls the operating system work flow, user authentication, data encryption algorithm, and other applications. The hierarchically organized file system of a SIM resides in persistent memory and stores data as names and phone number entries, text messages, and network service settings. Depending on the phone used, some information on the SIM may coexist in the memory of the phone. Alternatively, information may reside entirely in the memory of the phone instead of available memory on the SIM.

Resource: Basic LTE call flows and tutorials

Found this when surfing the web, maybe any of you will find it useful.
Most of the topics I've covered here, but this looks good for a Radio/Device reference.

Anniversary 40 years of mobile calls

I'm a little bit late, but still I think this is bigger or smaller anniversary for all of us and because of that all the best to all of you telecom-interested and/or telecom-engineers mates!

"The first mobile phone call was made 40 years ago today, on 3 April 1973."

Some other LTE resource

Just noticed that someone (Bandwidther thaks for sharing links mate!) put links to this blog on his forum. I went there and it looks like guy(s) are creating community which is worth participate in.
I did not read through, but on the first sight there are many sections including the LTE but also 2G, 3G and even the US version of 3G ;-)

Check it on your own

Resource: filtering, principles, measurements durring HO, and more on Radio part

Yesterday I found good resource on multiple LTE Radio topics covered by one site.
To Whom it may concern.

Enjoy!

Multiple LTE Radio topics

• How Handover Filtering by UE in LT?
• Handover principles and Handover measurements in LTE
• Handover Algorithm and Procedure in LTE
• What is AMC & its Algorithm in LTE  
• How UE Switch to Service types in LTE?
• PLMN selection in “IDEL Mode” for LTE-UE
•   
• and much more from radio side

Resource: RF and Microwave Engineering Tutorial Site

Lately I don't have spare time to read and prepare something for all of you.

Today I hit really good resource covering RF and Microwave and radio signal modulation in one place.
I wish I found that when I was at the University. For all of you who can find it useful.

Enjoy!
