The hottest PHS speeds up its withdrawal or makes

PHS' withdrawal has been a long-standing problem, but with the acceleration of PHS' withdrawal work around the world recently, PHS' withdrawal has become a hot topic and has been widely concerned by the industry. According to the rumor, before September 28, the operator PHS all withdrew and closed the core equipment. As early as January 2009, the Ministry of industry and information technology issued a notice requiring the PHS business to be divided in January 2011 from the experimental data: there are those suitable for metal experiments and non-metal experiments; By the end of the year, the frequency clearing and withdrawal work was completed, and the frequency used was unconditionally recovered, but PHS is still alive after so many years. This withdrawal is so urgent or making way for the acceleration of 4G spectrum of operators

Shanghai Telecom announced yesterday that from September 1, it will fully implement the PHS upgrade service to provide more advanced mobile communication services for PHS users. At that time, Chinatelecom will stop charging users for PHS communication fees. At the same time, several provinces have recently issued announcements to speed up the upgrading of PHS services, including Hubei, Guangdong, Shandong, Fujian and other provinces

4G competition among operators is intensifying. With the rapid development of 4G by China Mobile, the recently released data is that China Mobile has 13.943 million 4G users. At the same time, recently, the number of pilot cities of China Unicom and Chinatelecom LTE integration group has increased to 40 cities respectively, and the curtain of 4G competition has opened in an all-round way. As a limited spectrum resource, it is undoubtedly a particularly important factor in 4G competition

as we all know, the higher the carrier, the shorter the transmission distance of the signal, and the smaller the coverage area of the base station, so the low-frequency band is more conducive to the construction of LTE networks. It is reported that in the FDD spectrum, China Unicom obtains MHz and MHz bands, and Chinatelecom obtains MHz and MHz bands. There is no protection band in the middle, so there is a great possibility of interference. It can be seen that although China Unicom waited until FDD was approved and the pilot city expanded, the construction problem is the key at present. At the same time, China Mobile is also facing the demand for low-frequency spectrum

he tingrun, a consultant of the National Radio Spectrum Research Institute, believes that the low-frequency spectrum is extremely important for TD-LTE and subsequent evolution, because the number and quality of frequencies will become an important wind vane affecting the industry's investment in TD-LTE and subsequent evolution

at present, what operators can hope for is that the 700MHz frequency band of radio and television is globally recognized as a digital dividend spectrum, and the second is the 1900mhz-1920mhz 20MHz frequency cleared by PHS. According to the development plan of terrestrial digital television broadcasting coverage, it is expected that the digital conversion task will be completed in 2020. This also means that the release of 700MHz frequency band will not be earlier than this period. Therefore, the spectrum cleared by PHS is the focus of recent competition

it is reported that in 2002, the former Ministry of Information Industry issued the notice on the frequency planning of the third generation public mobile communication system, which planned the frequency of 1880 ~ 1920mhz as T. in the future, there will be great prospects for the use of clothing, shoes and hats, building energy conservation and other fields. The main frequency bands of DD include the frequency of 1900 ~ 1920mhz used by PHS, which is 20MHz

at a time when 4G development is in full swing, we certainly don't want to let the spectrum problem slow down. It can be seen that PHS accelerates its retreat or makes way for the 4G spectrum of operators. If the national radio regulatory authority does not issue new regulations, all operators with TD-LTE licenses have the right to apply for the use of PHS' standard specifications for frequency cancellation testing. In addition, we call on the government to come forward as soon as possible to determine the withdrawal time, otherwise it will take time for PHS to completely dismiss users of the quality management system in ISO9000, but the development of 4G is indeed imminent
