Is wifi saturated? whats coming up in wifi world?
Lately, i have been hearing this question a lot and decided to find an answer.
I believe that the field of wifi is very busy in the coming years, technology wise not so much change, the basic protocol remains same and so are the basic rules, but its more user-centric now and more real world scenario based. Lets take a look at the things coming up and soon in wifi
Lets divide the upcoming things in wifi in to technology based and user based.This time less text and more crisp no detailed technical analysis :-) , because most of these things have a roadmap of around 2015-2016, many of the TG's are in the nascent state.
In short, we have got all the three tracks covered IEEE is working on huge
Major PHY changes :
Minor MAC changes
where as WFA is working on IOT and End-User scenarios and applications.
So for coming 5 years i would say wifi has lots of work to do. Especially the standard 802.11ah and ad are very popular among engineers and companies and are highest attended TG's.
Any more new ideas/use cases for wifi ? Please share your opinion.

In short, we have got all the three tracks covered IEEE is working on huge
Major PHY changes :
- Spectrum : 3.7GHz, sub 1GHz, 60GHz
- Bandwidth : 1, 2,4,8 and 16 MHz
- Low power : Energey Efficient
- FSN OFDM : 64 subcarriers (Fixed Subcarrier Number)
Minor MAC changes
- All advanced WFA programs are P2P based.
- Fast Discovery
- Fast Connection,
- Efficient and Long powersave,
- QoS for Management,
where as WFA is working on IOT and End-User scenarios and applications.
So for coming 5 years i would say wifi has lots of work to do. Especially the standard 802.11ah and ad are very popular among engineers and companies and are highest attended TG's.
