4G battle, WiMAX and LTE Who?

By the end of September last year, the company begin operating the United States Sprint’s WiMAX brand XoHM to open the world’s first mobile WiMAX services, in January this year, Clearwire has launched commercial WiMAX services, while our country is also Taiwan’s WiMAX service started, which swept away the last market WiMAX technology development uncertainty. However, in the development of WiMAX in advance when a major step forward, WiMAX camp, but suffered a major blow, and LTE are stepping up the cloth to build a complete ecosystem, can be seen at two major 4G technologies will continue to battle time.

WiMAX and LTE for 4G with the mainstream technology

Before the International Telecommunication Union’s radio communications department announced as the next generation IMT-Advanced wireless broadband technology standards, including WiMAX, LTE, as well as Japan to VSF – OFCDM technology as the foundation of the XG-PHS. ITU IMT-Advanced for 4G communications standards on the titles of the technical specifications of the standard in October 2008 has been officially decided, that is, static transfer rate achieved 1Gbit / s, at high-speed mobile users can achieve the status of 100Mbit / s , it can be used as one of 4G technology, but the current action WiMAX (802.16e) and LTE are not ITU-R for IMT-Advanced set of goals, so the United States Association of Electrical and Electronics Engineers (IEEE) and 3GPP project take active steps to amend their standards to meet the ITU requirements.

According to the 2008 IEEE announced the next generation of WiMAX technology 802.16m System Description of the draft document, with a view to meet the IMT-Advanced requirements and compatible with the 802.16e standard, in line with the IEEE 802.16 Working Group requested that the standardization of 802.16m in before the end of 2009 was approved and completed, and the Global System for Mobile Communications GSM Association also announced the adoption of the 2008 End of the year the GSM technology of LTE as 4G technology as a mainstream technology.

The biggest advantage of WiMAX over LTE are the progress of technology development leader for two years, at a range of computing equipment to provide broadband wireless access of the contest, the first phase of WiMAX has been won, and the technology is ready to cover the current wireless local area network (wireless) nodes, WiMAX is ready to be called a technical, and in this battle of 4G gaining momentum. In addition, the technology is best suited to want to consider the deployment of broadband, but without a strong foundation of existing equipment, new markets, even in many developed countries, LTE technology be considered voice and data services from the long-term reunification, but LTE is still a large number of tests required.

Even though WiMAX technology is the expansion of wireless networks, but also may involve the use of telephone network voice protocol (VoIP) mobile phone deal with voice traffic, its cellular coverage in the absence of market attractive; On the other hand, LTE technology in the voice network top-level overlapping IP network, makes use of the existing basic equipment, transmission of voice traffic possible. From the two camps of action, we can see that the future will be time to enter the 4G communication are inevitable, but the LTE technology and WiMAX technology market battle will be more intense.

WiMAX and LTE chip to attack the market opportunities

Currently available commercial WiMAX service, which is a chip maker in terms of good news, Intel’s WiMAX hard laptop computer market, WiMAX deployment in Taiwan will have considerable room for growth, Intel’s WiMAX Program Office WiMAX ad hoc Li Guohui manager said that the Centrino processor technology will be built-in WiMAX laptop good selection, and Intel and Sprint the company’s very successful mode of cooperation, which is due at the cost of WiMAX technology on the edge, so that carriers do not in order to attract users to subsidize the cost of laptop computers, operators only need to focus on providing services related to WiMAX.

Sequans company on, WiMAX market deployment must also have a positive effect on thinking wide communications, vice president of Asia Pacific operations, said Robert Fogliani, new technologies must have its development time, such as the introduction of wireless technology to the market from flourishing spent nearly 7 years time, and the technical difficulty than WiMAX wireless high, industry is also more complex, and therefore the development of WiMAX technology is quite rapid time, and the Founding WiMAX technology shows the future users of WiMAX-related products will also be more demand to the greater, therefore, the chip maker to expand operations is a good opportunity for WiMAX market.

WiMAX technology in the face of gradually warming global service, from the third generation to LTE related manufacturers, is also faster, and actively complete industry as a whole ecosystem, with a view to following the LTE standard Express decided to launch commercial services, the pace to catch up with WiMAX. To observe from the chip maker, Qualcomm 2009GSMA at the General Assembly on global system for mobile communications, that is released a new generation of integrated 3G and LTE technology products MSM8960, shows its deep industry’s determination to LTE, Qualcomm vice president, Communications Products Alex Katouzian said, LTE are recognized by the ITU’s 4G technology standard, LTE technology in intensive urban areas through the use of new spectrum TDM, as well as wider bandwidth, complement the existing 3G and future HSPA + deployment. HSPA + and LTE can be outside the coverage area, to ensure that the entire network in a consistent user experience and to provide similar user data transfer rate and performance, In view of this, high-pass the current products will be introduced to a lock for the 3G based chip multi-mode LTE.

In addition, Infineon is also up at 2009GSMA new LTE RF chips, can provide with the DigRF digital broadband interface 2G/3G/LTE function LTE network at the highest data transfer rate up to 150Mbit / s. Other network equipment manufacturers in the layout of LTE technology is also quite positive, such as Ericsson recently launched 2009GSMA on the evolution of the core (EPC) to support the network carriers portfolio into LTE network. In addition, Ericsson and TeliaSonera have signed a commercial LTE network contract, Ericsson said that the action 4G broadband network will provide higher data transmission speed of action, better interactivity and quality.

WiMAX and LTE dual-mode chip trend of the times

ABI predicts that WiMAX and LTE to integrate a new generation of 4G technology, multi-mode single-chip is expected to be listed in 2009, in other words, when the mobile broadband communications will be based on the existence of dual-band manner. Regardless of the development of WiMAX or LTE chip technology providers, most dual-mode chips will consider the future development trends, is also being associated chip R & D Products.

Focus on mobile WiMAX technology, Altair Corporation, in the last month, held on the first to display 2009GSMA integrated WiMAX, LTE and XG-PHS JAPAN standard tri-mode chip, Altair company said previously the company only focused on the development of WiMAX chips, but because of LTE technology and WiMAX technology uses similar modulation techniques, and the future of the two technologies will coexist, rather than competitive posture, coupled with ITUnes will also be Japan’s XG-PHS as one of the technical standards for 4G, it will upgrade Altair 4G chipset to manufacturers of positioning, developed a tri-mode chip, and this chip with low power consumption can be easy to switch to a variety of band characteristics, including a variety of suitable cell phone, laptop computers and other portable devices products.

The future regardless of how the development of WiMAX and LTE, these two technologies have entered the halls of the fourth generation of communications, the two technology vendors competitors will be at the time 4G continued confrontation, while the direction of development up to 4G technology manufacturers, will be optimistic about the future of the two integrated technologies.
