Comparing Wireless G To Wireless N

Of the four basic types of wireless networking standards, three bear similar characteristics. The 802.11b, or B, standard is fast being replaced by wireless G, which is in turn being overtaken by the not-yet-finalized wireless N.  These two facets of the 802.11 set of standards, “G” and “N”, are remarkably similar, with the latter simply being an extension of the implementation.  An evolution in the use of wireless services, if you will.

Wireless G provides an optimum transfer rate of 54Mbps, and allows for numerous users over the area of coverage.  It transfers over radio frequencies in the 2.4Ghz range.  This is the type of equipment current used for local wireless networks as those found in restaurants and other local “Hotspots”.  It was developed from the earlier wireless B, and offered the ability to handle more users coupled with a faster rate of data transfer.  Even though it is more expensive to incorporate than the earlier form, the benefits make it a more cost-effective choice.

Wireless N extends the G implementations in much the same way.  It allows for throughput nearly 50% faster, at 100Mbps, and adds stability to users on the network.  Wireless N incorporates MIMO (Multiple Input / Multiple Output) technology, there are are than one sending and/or receiving unit for the work, operating in tandem.  This allows for greater data speed, while increasing the number of users that are able to connect to the network.

Is the N version better? Certainly, it is.  But a word of caution would be in order, because wireless N has not yet been finalized, and equipment available for it now may become quickly outdated when the standard is complete.  In layman’s terms, this means that the set of rules are still being discussed, and problems and technicalities worked out.  The final standard is expected to be released late this year, at which time most devices made for wireless N will contain the same operating guidelines.  It is here now, but be careful that you buy equipment based on the final set of rules.
