Comments Section – Care about them? Then you have to read this!

Blog
So  I was browsing some technology stuff on the internet. Specifically reading this one article titled " The Moon is Now a Wi-Fi Hotspot " Seeing such a flashy title, a communication enthusiast will never turn it down. So I read this great new discovery that the moon could potentially let the astronomers on moon stream netflix when they feel like.  But not what this post is about, when you read articles or if you watch your favorite youtube video there is a big long comments section in the bottom. If you do not know, those are the sections which are filled by the so-called "jobless" but not on a science article. This interesting article had the following first comment, and I bet this will be one of the nerdiest…

Establishing Radio Contacts at 60 GHz for Truck Platooning

Establishing Radio Contacts at 60 GHz for Truck Platooning

Projects
This was my final graduation project which I carried out at TNO Automotive at Helmond, Netherlands. ABSTRACT: This thesis studies the channel propagation characteristics of 60 GHz communication band to use as a secondary redundant link for Truck Platooning. Truck Platooning uses ITS-G5 as the main communication link. Extensive measurements are taken in indoor and outdoor environments to analyze the channel characteristics for various channel configurations. Channel parameters retrieved from measurements are presented and the performance of the communication channel is evaluated. Line-of-sight (LOS) and non-LOS (NLOS) scenarios on the lines of vehicular communication are considered. It is observed that multipath doesn’t affect the communication much in the environment where there are metallic objects. In addition, asphalt road helps in the propagation of signals thus better communication can be expected. This…

Investigation of membrane stretching in BCB bonding

Investigation of membrane stretching in BCB bonding

Projects
This project deals with the investigation of thermal expansion in the bonding of IMOS (Indium Phosphide Membrane on Silicon) on top of SOI (Silicon on Insulator) Wafer. It has been reported that the wafer undergoes stretching during the bonding process. The work done in this research is to identify the causes of stretching, we believe that the stretching that occurs is due to the BCB coating that helps in bonding the two layers. The experiment is conducted with various parameters to investigate whether the stretching is actually caused because of the BCB stress.

Latency Investigation in IEEE 802.11ad

Projects
One of the key parameters to be considered in any communication is the latency (delay) associated with it. 60 GHz has been in the limelight for quite some time considering it provides wireless communication at Gigabit per second. IEEE 802.11ad has been developed extensively for the standardization of this 60 GHz band. This paper is an investigation of the latency associated with the IEEE 802.11ad standard. It specifically deals with polling based TDMA MAC protocols and the CSMA/CA algorithm that this standard uses in MAC and also the coding scheme used by this standard.   Download the full report here :

Bachelor’s Graduation Work

Projects
ROADWAY MISHAP POSITIONING AND SMART TRAFFIC REGULATION WITH ADVANCED RADIO DATA STREAMING   P.C.DINESH RAO, S.MANIGANDAN, R.SARAN RAJ Supervised By, Mr.J.MANIKANDAN- Asst.Professor Grade 2 Sri Sairam Engineering College, Chennai, India. Presently, traffic has increased with over-speeding and rash driving predominantly causing accidents. In this project, the concept of an Automatic Crash Notification is discussed. A message will be sent to a traveling ambulance or a nearby hospital, after an accident happens. Upon reception of this message, the ambulance will reach the accident site. When an accident occurs, an inbuilt intelligence system in the afflicted vehicle is activated and it automatically sends select details of the accident to the appropriate emergency handler for response using GPS(Global Positioning System). The vehicle’s position is sent to a rescue team using GSM(Global System for…

#1 – After a long wait !

That Thesis
The month is February and the year is 2016. This time of the year when almost all the master students at my university got their project and sitting happily in their chairs working on their beloved thesis. I belong to the electrical engineering department where there we had to do mandatory two internship. I was done with my internships at the beginning of January and with my exams at the end of that month. It is at this point, where i contacted my supervisor for my graduation project. Every supervisor plays a very important role in a project and this person who i chose as my supervisor was one of the best in the field that i was interested in. His main focus was on antenna design and working on…

Conclusive Statement – The Winner is..

Conclusive Statement – The Winner is..

Wireless
Dear readers, this will be the last post pertaining to this series of blog posts. Before I go the conclusive statement, lets see what we have seen so far very shortly. Firstly the topic chosen was about the standardization of the 60 Ghz frequency band.  We saw about various organizations competing for the race and about the various features of the 60 Ghz band which is one of the frequency band on which the future communications will be based upon. Then we saw about the highlighting beam forming protocol and the beam forming training of this standard. Lastly in the previous post we saw about the comparison of the various organization's technologies to draw a conclusion. HIGHLIGHTS OF IEEE 802.11 ad: The beam forming training protocol enables highly directional communication.…

So Which One is It Now

So Which One is It Now

Wireless
Hello readers, we are coming to a close on this 60 Ghz band soon . In my previous posts, we have been seeing about the technology introduced in this 60 Ghz band by IEEE 802.11 ad - beamforming training associated with the 802.11 ad and the enhancement that has been made to  connect with the PCP/AP without preceding coordination. In this post we will see about what various organization has to contribute to this 60 Ghz band and then which organization hold strong position with respect to the standardization of this frequency band. COMPARITIVE ANALYSIS: BEAMFORMING:  We have already seen about the beamforming of the IEEE 802.11 ad, so lets see about the rest. The ECMA-387 uses special frames called TRN frames to determine the appropriate antenna weight vectors. The beam…

IEEE 802.11 ad Beamforming Protocol

IEEE 802.11 ad Beamforming Protocol

Wireless
Hello all, and in the previous post we saw about the general beamforming training which could be associated into different medium access schemes and the association process.  This post talks about the association beamforming training associated with the 802.11 ad and the enhancement that has been made to  connect with the PCP/AP without preceding coordination. ASSOCIATION BEAMFORMING TRAINING: The beamforming training between the PCP/AP and an unassociated station cannot rely on coordination preceding to the beam training. The PCP/AP uses its beacon sweep during the BTI, as an initiator sector sweep for all stations to overcome the challenges of directional link setup. The Sector Sweep (SSW) frame specific control fields are added to the beacon frame. To allow multiple stations to respond to a beacon sweep without coordination, the A-BFT…

Beam-Forming Concepts

Beam-Forming Concepts

Wireless
Hello readers, warm greetings and in the last post we saw about the communication at the 60 Ghz range, the design considerations and this week the subject that we are focusing is about the beamforming concept.  But before getting into the topic, we should know why we are going for this concept and why not use the old MIMO concept. Reasons for using the beamforming concept : We have already seen that one of the main problem with the 60 Ghz band is that it suffers from high signal path loss and when we used the Frii's equation for finding the losses, the 60 Ghz band suffers from 28 dB more loss than the present 2.4 Ghz band. In order to address this situation we have to use a large…
