Wi-Fi: Future Roadmap and LTE

At the WBA Wi-Fi Global Congress, Intel provided a good summary of the way things are progressing in the WiFi world, including the standards updates that are going on. Luckily I found a video by the same author in from an IEEE conference which is also embedded below.

Wi-Fi is becoming important and a useful rule of thumb is that the spectrum in 5GHz is roughly around 10 times that of 2.4GHz and the spectrum is 60GHz is roughly around 10 times that of 5GHz. (not all spectrum is available everywhere so just use this as a rough guide).


As I mentioned in a presentation I gave this week, there are three different approaches being proposed at the radio level; LTE-U, LAA and LWA. I wrote a post on LWA not long back on the 3G4G blog here.



Dave Wright from Ruckus Wireless has kindly shared a recent presentation on different proposals for LTE operation in unlicensed spectrum. The timeline above shows how quickly things are moving. Here is a the presentation

It would be important from Wi-Fi vendors point of view that LTE-WiFI Link Aggregation is standardised as part of Release-13 as there would be an option which would be agreeable to everyone.

Ubiquisys to focus on 'indoor metro' and enterprise at #MWC13

Our intelligent small cell technology has delivered 99.999% availability in some of the world’s most demanding indoor metro deployments. And we’ve doubled the number of tier 1 systems integrator partnerships from 2 to 4, meaning that Ubiquisys intelligent small cell tech is now embedded in the major slice of commercially available solutions.

LTE multi-mode small cells – focus on indoor metro and enterprise
Working with silicon platforms from long-term partners Texas Instruments and Broadcom, Ubiquisys will be demonstrating a range of novel LTE/3G/WiFi products that can handle the immediate need to ramp capacity and provide an adaptive evolution to LTE provision. Ubiquisys has deployed outdoor small cells but our focus is on intelligent cells for indoor public spaces, where the majority of mobile data is consumed. The combination of abundant sites, simple installation and automatic operation means that indoor cells can be economically deployed in much larger numbers for a sustainable ramp in integrated 3G/4G/WiFi capacity (see our infographic on indoor/outdoor small cells).
