5571.全球3G4G设备市场报告（2016-2020年）
[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2016-08-10]
Advanced mobile phone system (AMPS) network technology was used in 1G. AMPS was a voice-only network, operating on the 800 MHz band that was permanently switched off in 1999. AMPS was an old radio technology, and its operation was similar to regular radio transmission such as ultra-high-frequency (UHF) radio, where the 800 MHz band was split into many channels using frequency division multiple access (FDMA). Each channel was 30KHz wide and, hence, supported only 395 mobile phone users per cell tower. The tower estimated the signal strength of each user and allotted channels to them. The tower ensured that these channels were reused without interference by multiple towers.

5572.全球潜水服市场报告（2016-2020年）
[纺织服装、服饰业] [2016-08-10]
Diving suits are the apparel used by divers to protect them from the underwater environment. They are categorized into wetsuits and drysuits, based on their applications and technology. A wetsuit is manufactured using foamed neoprene, which provides thermal insulation, buoyancy, and abrasion resistance. Bubbles of nitrogen gas trapped in the material of the wetsuit reduce thermal conductivity, decrease the density of the suit, and provide buoyancy in water. Wetsuits are mainly worn by surfers, divers, windsurfers, and triathletes.

5577.全球移动电话保险市场报告（2016－2020年）
[金融业,计算机、通信和其他电子设备制造业] [2016-08-09]
The mobile phone insurance refers to the insurance or coverage taken by the cell phone users looking to insure their cell phones from different kinds of damages or losses. The coverage is provided to the insured in case of losses and damages against riot, strike, malicious damage, terrorist activities, fire, theft, accident, and fortuitous circumstances. Mobile phone insurance helps evade expensive replacement costs in case of mobile phone breakdown. In most cases, liquid damage due to water is a common problem. Due to this, the customer without an insurance coverage has to pay full price for a replacement, which is a loss for the customer. The replacement cost is generally higher in the case of contract phones. Cell phones that are purchased on a contract basis are subsidized across the term of the contract.
