Seven trends in the enterprise Wi-Fi market in 2014
1. With the emergence of more and more 802.11ac-enabled devices, vendors have reduced the cost of 2x2 802.11ac access points (APs), so the adoption rate of 802.11ac APs will continue to climb.
2. Cloud solutions for Wi-Fi management and services will continue to provide small and medium-sized enterprises (SMEs) with more technology to serve enterprises.
3. Wi-Fi-based location analysis will play an increasingly important role for organizations to help them enhance business intelligence analysis, determine security strategies and enhance customer / user Wi-Fi experience.
4. Analysis is particularly important to correlate customer data points (location, application, device type, trends, etc.).
5. The popularity and integration trend of BYOD solutions and equipment management will continue to extend.
6. With Passpoint-certified / ready smartphones entering the market, Hotspot 2.0 will enter the enterprise as another way to provide Wi-Fi access.
7. Social media (Facebook, Google+) as user Wi-Fi login credentials will be distributed across organizations to provide guest access.
Top Ten Trends of Carrier / Service Provider Wi-Fi Market in 2014
1. A large-scale Hotspot 2.0 roaming alliance will be established to automatically and securely connect to a Wi-Fi network composed of thousands of roaming partners and millions of APs. These partners will include a large number of public places with indoor Wi-Fi deployments.
2. Enterprises continue to seek managed Wi-Fi service providers to deal with many issues, such as network complexity, new services, and technical deficiencies in many IT organizations.
3. Positioning services will bring profit opportunities to companies that can provide managed services.
4. As technologies such as 802.11r and 802.11k enter mobile devices and APs, seamless Wi-Fi switching will come true. Even if the user enters another coverage area, the smartphone does not need to be attached to the associated AP. With Wi-Fi to achieve seamless switching, its experience is comparable to cellular services.
5. Global cable MSO will continue to embrace Wi-Fi technology, help it avoid buildings, increase its service package, and obtain the best location. This will set the stage for a roaming relationship with MNO in the future.
6. Continue to work on the integration of Wi-Fi and LTE small cells, but small cells will not emerge in large numbers by 2015.
7. Carrier-grade Wi-Fi management system began to catch up with carrier-grade Wi-Fi network infrastructure.
8. Continue to work on strategic solutions to help smartphones choose between Wi-Fi and cellular connections. This problem is very complicated and it will take several years to solve it.
9. 802.11ac continues to break into the market, and the second phase of multi-user MIMO advancement marks a substantial step forward. This will enable the access point to synchronize with up to 4 independent shunt smartphones.
10. Through the integration of cellular and Wi-Fi, no matter how much network capacity is added, it will always be a big deal. With the increasing density of networks, more spectrum and spectrum sharing technologies will be needed.
Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material
Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
