After writing up a storm about the next-generation cellular Long-Term Evolution standard a few weeks ago, I noticed that several commenters were confused, critical or just plain wrong about LTE and WiMax, the other 4G network. So I called a few people and tried to figure out the salient differences between the two. First, both are 4G technologies designed to move data rather than voice. Both are IP networks based on OFDM technology — so rather than rivals such as GSM and CDMA, they’re more like siblings. But sibling rivalry does exist, so there’s still plenty of differences to hash out.
Let’s start with the genesis of the two technologies.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.
