WiMax Vs LTE : future mobile communication trend ?


After a long debut about the next-generation cellular and WiMax deployment in the near future for the new communication module, seems they will show something to us, LTE and WiMax for future communication module. Both are still struggling to prove their capability, performance reliability and signal efficiency towards higher bandwidth requirement from community. Whihc one will win the segment? However, before we further jump into conclusion, some clarification need to be mentioned here. There are still some people really confused about those two; what are they? what they do? how great performance they can produce? how reliable they are?..Well, if we put these two together, they are almost the same. First, both are 4G technologies designed to move data rather than voice. Both are IP networks based on OFDM technology for fixed (802.16) and OFDMA (802.16m & LTE) for mobile — so rather than rivals such as GSM and CDMA, they’re more like siblings. But does the siblings all the same. no right? So, there a plenty of difference among them.

WiMax is based on a IEEE standard (802.16), and like that other popular IEEE effort, Wi-Fi, it’s an open standard that was debated by a large community of engineers before getting ratified. In fact, we’re still waiting on the 802.16m standard for faster mobile WiMax to be ratified. The level of openness means WiMax equipment is standard and therefore cheaper to buy — sometimes half the cost and sometimes even less. Depending on the spectrum alloted for WiMax deployments and how the network is configured, this can mean a WiMax network is cheaper to build. The speed for the WiMax (802.16) is up to 70 Mbps, while the mobile WiMax (802.16m) is up to 100Mbps.

Malaysia is still in progress in deploying WiMax Technology, but the condition is stillon “testing” for so long . Do not know why. Izzi is a new name in Malaysian Broadband challange and the claim to have 4G connection. Check it first before you subscribe (affraid only for the best effort - as another slumpy monopoly carrier advertise their broadband). Sprint Nextel will aslo deploy this WiMax technology to become their 4G carrier.

Whilst, The LTE, (3GPP Long Term Evolution), is the next-generation network that beyond 3G. In addition to enabling fixed to mobile migrations of Internet applications such as Voice over IP (VoIP), video streaming, music downloading, mobile TV and many others, LTE networks will also provide the capacity to support an explosion in demand for connectivity from a new generation of consumer devices tailored to those new mobile applications. Most of the Telcos believes LTE will be the standard chosen by 80 percent of the carriers in the world

LTE is the natural evolution of 3GPP GSM and WCDMA networks. It is also an evolution candidate for 3GPP2 CDMA networks. Efforts are underway to harmonize the standards. LTE itself is a new paradigm in access, with a new modulation technique, OFDM (Orthogonal Frequency Division Multiplex) or some people said it use Orthogonal Frequency Division Multiple Access (OFDMA), and antenna technology, MIMO (Multiple Input Multiple Output).

Nortel, Nokia , LG, and Alcatel-lucent are among the group who perform test on LTE deployment.

To much technical right?

The funny thing about technology businesses is that technology counts for so little in the final result. Politics, human nature, and all of the frailties inherent therein trump the technology issues in virtually every case. So, logically: LTE will win.

The cellular carriers control the market, so they control the decision. Now if the WiMAX camp could come up with something that was phenomenally better, then the cellular carrier would have to look more closely at this, but unfortunately, physics works the same for everyone. With no compelling technical advantage for WiMAX, LTE will win. Agree?

WiMAX Broadband Wireless Technology Access

What is WiMAX
WiMAX (World Interoperability for Microwave Access), based on the IEEE 802.16 standard, is expected to enable true broadband speeds over wireless networks at a cost point to enable mass market adoption. WiMAX is the only wireless standard today that has the ability to deliver true broadband speeds and help make the vision of pervasive connectivity a reality.

There are two main applications of WiMAX today: fixed WiMAX applications are point-to-multipoint enabling broadband access to homes and businesses, whereas mobile WiMAX offers the full mobility of cellular networks at true broadband speeds. Both fixed and mobile applications of WiMAX are engineered to help deliver ubiquitous, high-throughput broadband wireless services at a low cost.

Mobile WiMAX is based on OFDMA (Orthogonal Frequency Division Multiple Access) technology which has inherent advantages in throughput, latency, spectral efficiency, and advanced antennae support; ultimately enabling it to provide higher performance than today's wide area wireless technologies. Furthermore, many next generation 4G wireless technologies may evolve towards OFDMA and all IP-based networks as an ideal for delivering cost-effective wireless data services.

Intel is poised to deliver the key components needed for successful WiMAX networks. It delivered the fixed WiMAX solution, Intel® PRO/Wireless 5116 wireless modem, and is now shipping a fixed/mobile dual-mode solution, Intel® WiMAX Connection 2250. This highly cost-effective solution was designed to support both standards with an easy upgrade path from fixed to mobile and is expected to further accelerate the deployment of WiMAX networks.
