WiMax has officially become a 3G standard, which is encouraging for enterprises that have been supporting WiMax. beidian is one of them. After giving up the 4G switch, which is represented by WiMax, beidian truly saw the dawn of the next Industrial cycle from the "Turning Positive" of WiMax.
"
Although the four major carriers are conducting WiMAX tests with no explicit intent, the specific investment and scale are still a sensitive topic.
Yesterday, it was reported that China Unicom had started the WiMAX test very early. In 70 million, China Unicom had a Gbps frequency, so it planned to build a fixed WiMAX in 21 provinces with a Gbps frequency, with a
Maravedis, an authoritative U.S. market research agency, announced the latest survey report that WiMAX users worldwide increased by 50% to 1.369 million in the third quarter of this year compared with the same period last year, in the first three quarters of this year, the service revenue of WiMAX operators reached $0.668 billion.
According to the survey report, the total revenue of global
The transmission of wireless technology is based on radio waves, which occupy a certain frequency band. In the era of resource shortage, frequency band resources are also not rich. This brings competition for our wireless technology. At present, there are a variety of wireless technologies, each of which has different standards. However, WiMAX wireless broadband technology is not optimistic in China.
In recent years, with the continuous development of
In 70 million, the media reported that China Unicom plans to invest yuan to build a WiMax test network in 21 provinces with the right to use the GHz band. In this regard, some insiders told Netease technology that, the feasibility of large-scale network construction with WiMax technology in the 70 million GHz band is very low. The investment of Yuan is also too small for the trial network scale in 21 provin
China Telecom once again showed its strong interest in WiMAX at the global WiMAX summit held yesterday on August 18. Zhao ye, China Telecom's technology department, said WiMAX has independent target networking capabilities and is a good supplement to fixed networks.
At the beginning of this year, China Telecom officially became a member of the
Recently saw a classmate in order to enhance the mobile phone GPS signal, the antenna DIY to the outside, pulled a very long antenna, their own in the suspicion that this is in line with the principle of antenna design, can really make the signal enhancement? So find the following article to learn.1. RFID Fundamentals RFID (radio frequency identification) is a
Both VoIP and WiMAX pose a threat and challenge to traditional technologies in their respective areas. The combination of them will also make new demands and new effects on the development of communication technology.
Priority support for VoIP services
For WiMAX, VoIP voice service as a basic business type must be supported first.
WiMAX network based on IP pro
NXP Semiconductors, formerly known as Philips semiconductor, has announced that the company uses a full range of transceiver products using WiMAX 2x2 MIMO (Multiple Input Multiple Output, Multiple inputs and Multiple outputs) technology, this series of products is specifically designed for mobile and handheld applications. To fully support the adoption of mobile WiMAX technology, the new series of NXP Semic
As a standard for wireless broadband MAN, WiMAX technology has great advantages over the previous 3.5GHzMMDS in terms of non-line-of-sight transmission and spectrum utilization efficiency. As one of the core of the Next Generation Network, the Softswitch Technology Based on the IP network is very mature in terms of comprehensive service access and QoS level assurance, and will replace the existing PSTN devices. This article describes the performance t
Mcwill, as a broadband access product with proprietary intellectual property rights in China, has received close attention in the industry recently. The voice of "WiMAX is likely to be replaced by Chinese standards" is beginning to sound in the industry.Mcwill, as a derivative product of TD-SCDMA, is currently positioned in fixed wireless broadband technology. The new R5 version is similar to Wimax in terms
Entrusted by a world-renowned communication equipment manufacturer, we are looking for the following talents. We recommend the following:I. WiMAX/CDMA OMC product director and Technical ManagerResponsibilities:1. WiMAX/cdma omc product plan or product market guide, including product market positioning, marketing strategy and competitor product analysis;2. The WiMAX
Alcatel-Lucent said on Tuesday that the first regional WiMax network will appear in Russia, and Alcatel-Lucent will provide WiMax equipment for it.Synterra, a Russian telecommunications service provider, chose Alcatel-Lucent to build a WiMax mobile communication infrastructure network covering some towns with an average population of 0.1 million.This elementary
The antenna pattern is also called the Radiation Direction map (radiation pattern), the far-field direction map (Far-field pattern). The antenna gain is not obtained from the pattern above, and the directional coefficients are obtained from the direction graph. Antenna gain = directional coefficient * antenna efficienc
Mobile phone antennas can be divided into PIFA antennas and Single Pole antennas. As debugging becomes more difficult, a new IFA antenna is added.
PIFA AntennaPIFA antenna has the same requirements on antenna height and area. Generally, the dual-band height must be above 5mm. The proposed height of PIFA antenna must b
I. TD-SCDMA and WiMAX Technical Characteristics
In recent years, the most popular topic in the communication industry is the development of 3G and WiMAX technologies. In the 3G standard, the time-division Synchronous Code Division Multiple Access (TD-SCDMA) system, which is developed by China and has proprietary intellectual property rights, is particularly prominent. Compared with the other two 3G standard
1. Is the effect of placing an external antenna in the trunk of the car station worse than that in the middle of the roof?A: There are four main indicators of the vehicle's antenna: maximum withstand power, center frequency, bandwidth, and standing wave ratio.The first indicator is generally not taken into consideration, because generally, the maximum withstand power of the external
When you are using a wireless network, you are sure to experience wireless network signal quality problems. To solve these problems, in addition to reducing the shielding, reduce the interference of the same band equipment, the most effective way is to replace the high gain antenna, with the antenna to enhance the transmission effect of wireless network, coverage. However, the purchase of wireless gain
The Relationship Between WiMax and WiFi is not in the same category. WiFi is a standard IEEE802.11x-related interoperability organization of the wireless LAN, wiMax is a standard IEEE 802.16x-related interoperability organization for wireless MAN. The two are applicable to different application types.
Compared with WiFi, WiMax has better physical layer and MAC l
In general, our common antenna tests in engineering practice are divided into the following types:
Near-Field Test
In the near-field antenna test, the distance from the test probe to the plane of the tested antenna port is about 3 λ 5 λ. In this case, the antenna test is near-field test.The near-field
