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. The association beamforming training and two level beam forming training are the fundamental elements of this standard. The two level training includes the following.
- The association beam training aligns antenna beams between a station and a central network controller while direction between the devices is unknown.
- The two level training reduces the beam training search space using its primary coarse-grained training stage that relies on predetermined virtual antenna sectors.
With the fully trained transmit and receive antenna configurations, IEEE 802.11 ad reaches its maximum throughput of upto 7 Gbps. Another highlighting feature of this standard is the combination of the hybrid MAC layer and the novel beam training protocol which we have already seen before. The standard follows a highly secured process resulting from short tranmission distances due to oxygen absorption and narrow antenna beam width. High level of frequency re-use enabled communication needs of multiple customers within a small geographic region can be satisfied. One more useful highlight is that Fiber optic data transmission speeds possible. The best feature that seperates this standard from the rest of the proposed protocol is that it allows backward compatibility meaning the network need not be rebuilt again.
Looking at all these highlighting features of this standard, we could conclude that IEEE 802.11 ad will lead the race in standardization of this 60 Ghz band and emerge victorious among the other proposed standards. Before the close of this post I would like to highlight the role of 60 Ghz communication in 5G era.
ROLE OF 60 GHZ communication in 5G Era:
One of the important focus of 5G communication is to introduce communication at new frequencies in the mm wave frequency bands inorder to deal with scarcity of spectrum at lower frequency bands using large bandwidths . With this in mind and the technology that we have seen so far associated with this standard, we could see IEEE 802.11 ad is a very useful tool to realize the 5G technology.
I would like to thank my university professor Dr.Peter Smulders who has already published research papers on the same lines, who is my internship mentor for giving me good insights on IEEE 802.11 ad and the professor for this course Dr.Smits, who has given us some good insights about the standardization processs.
I would like to thank all my readers for this wonderful journey on 60 Ghz band and we would soon see on someother time starting on the same standard technologies.
Thanks and Regards,
