Millimeter Waves (IEEE Uwave: WiFi/WiGigAccording to IEEE Spectrum, May 2013, By the end of this decade, analysts say,50 billion things such as these will connect to mobile networks.
– consume 1000 times as much data as today’s mobile gadgets,– at rates 10 to 100 times as fast as existing networks can support.– New technology 5G beam-forming Antenna that could send and receive mobile
data faster than 1 gigabit per second over distances as great as 2 kilometers– designed to operate at or near “millimeter-wave” frequencies (3 to 300
gigahertz)– Bands lower on the spectrum very heavily used: 4G networks have just about
reached the theoretical limit on how many bits they can squeeze into a givenamount of spectrum.
IEEE 802.11ad– The IEEE 802.11ad standard is aimed at providing data throughput speeds of
up to 7 Gbps.– To achieve these speeds the technology uses the 60 GHz ISM band to achieve
the levels of bandwidth needed and ensure reduced interference levels.– the aim is that it will be used for very short range (across a room) high volume
data transfers such as HD video transfers.– When longer ranges are needed standards such as 802.11ac can be used

LTE-WiFi Handover: The Challenges Premature Wi-Fi Selection: As devices with Wi-Fi enabled move into Wi-Fi
coverage, they reselect to Wi-Fi without comparative evaluation of existingcellular and incoming Wi-Fi capabilities. This can result in degradation of end userexperience due to premature reselection of the Wi-Fi. Real time throughput basedtraffic steering can be used to mitigate this.
Unhealthy choices: In a mixed wireless network of LTE, HSPA and Wi-Fi,reselection may occur to a strong Wi-Fi network, which is under heavy load. Theresulting ‘unhealthy’ choice results in a degradation of end user experience asperformance on the cell edge of a lightly loaded cellular network may be superiorto performance close to a heavily loaded Wi-Fi AP. Real time load based trafficsteering can be used to mitigate this.
Lower capabilities: In some cases, reselection to a strong Wi-Fi AP may resultin reduced performance (e.g. if the Wi-Fi AP is served by lower bandwidth in thebackhaul than the cellular base station presently serving the device). Evaluationof criteria beyond wireless capabilities prior to access selection can be used tomitigate this.
Ping-Pong: This is an example of reduced end user experience due to ping-ponging between Wi-Fi and cellular accesses. This could be a result of prematureWi-Fi selection and mobility in a cellular environment with signal strengths verysimilar in both access types. Hysteresis concepts used in access selection similarto cellular IRAT, applied between Wi-Fi and cellular accesses can be used tomitigate this.

Example of Dynamic Spectrum AllocationTV white space (TVWS) extends Wi-Fi into new spectrum with better
coverage
• TVWS has superior propagation and extends the reach of wireless networks andit enables:
• Wireless networking with longer range– TVWS Wi-Fi network can be established with fewer APs / Repeaters– TVWS Wi-Fi as a supplement to current Wi-Fi, can fill the coverage holes that are not
covered by current Wi-Fi
