The term ultra-wideband ( UWB ) was first proposed by the US Department of Defense in 1989. Because ultra-broadband can coexist with other communication systems, ultra-broadband has developed rapidly, and the market application is broader.
UWB technology is a new type of wireless communication technology. It directly modulates impulse pulses with very steep rise and fall times, so that the signal has a bandwidth on the order of GHz. Ultra-wideband technology solves the major propagation problems that have plagued traditional wireless technology for many years. It has insensitivity to channel fading, low transmit signal power spectral density, low interception capability, low system complexity, and can provide positioning accuracy of several centimeters advantage.
Road to development
At the 2011 China International Information and Communications Exhibition, Guoren Telecom launched the Ultra-Wideband Digital Optical Fiber Distribution System (UW-DDS), which is the latest solution that can achieve multi-standard multi-service common access, collaborative development, and joint construction and sharing. The National Grand Theater and other applications have achieved great success.
Huawei released and highlighted the next-generation bearer network architecture U2Net (Ubiquitous Ultra-broadband Network Architecture) built by Huawei at this year's communications exhibition. U2Net is oriented to IP video and cloud applications, and can achieve 100M bandwidth access capability through an end-to-end ultra-broadband network architecture. At the same time, U2Net will further enhance the flexibility of the network to adapt to new services based on storage and software definition.
Recently, Alcatel-Lucent announced the launch of enhanced broadband products to further promote the development of ultra-high-speed broadband services. Using the first commercialized VDSL2 vectorization technology, Alcatel-Lucent will help operators significantly increase the speed and capacity of existing copper wire access networks, and bring broadband services that exceed 100Mbps to corporate users and ordinary consumers.
trend
Although UWB has been proposed for nearly 30 years, its development speed is obvious to all. With the increase of ultra-wide rate, the future development of the network also has new characteristics. The combination of ultra-broadband and cloud services is the best development path for future operators of intelligent information highway managers.
1. Buy power banks from qualified factory,do not focus on cheap price
only. Batteries, circuit boards have certain fixed costs, higher quality
batteries, the higher purchase cost.
2. Better choose poly-mer
batteries. Polymer batteries output efficiency is relatively stable, but
also has a light weight, safe and efficient.
3. Consider shell beauty at the same time, pay attention to the shell strength and heat resistance.
4. Do not just focus on the conversion rate.
