由于WiMAX的速度比3G快,基站的覆盖范围比3G大,因此就产生了“WiMAX能否取代3G”的问题。但是实际上,WiMAX与3G在本质上是不同的。WiMAX是一种无线城域网(WMAN)技术,而3G是一种广域城域网(WWAN)技术,两者分别立足于MAN与WAN两种不同领域的技术,两者的基础架构截然不同,WiMAX的着眼点是实现宽带无线化,而3G则更多地是实现无线宽带化。因此。WiMAX与3G将不是替代,而是优势互补,既是竞争,又是互相促进。 Because WiMAX is faster than 3G and base station coverage is larger than 3G, there is a problem of whether WiMAX can replace 3G. But in fact, WiMAX and 3G are essentially different. WiMAX is a wireless metropolitan area network (WMAN) technology, and 3G is a wide area metropolitan area network (WWAN) technology, both based on MAN and WAN technology in two different areas, the two infrastructure is very different , WiMAX is the focus of broadband wireless, and 3G is more to achieve wireless broadband. therefore. WiMAX and 3G will not be alternative, but complementary advantages, both competition, but also promote each other.
