Recently, I mentioned that wireless LAN capabilities are becoming integral to LAN deployments as a whole. I speculated that perhaps wireless LANs would become the preferred method of connecting to a network - at some point superseding cabling options. You had mixed reactions.However, most who responded pointed to persistent obstacles - bandwidth, security and interference.One thing I didn\u2019t mention about the bandwidth available through WLANs is that it\u2019s shared - so many of you pointed that out to me. That 54M bit\/sec available through IEEE 802.11a sounds great until you realize that each workstation has to share that bandwidth.Here\u2019s one reader\u2019s reaction:\u201cWhile you make some interesting points I think you are overstating WLANs role. 56M bit\/sec IS probably fast enough for most people, but remember this is shared medium, NOT per user. Don't get me wrong, WLANs are great, I use them frequently, but it's still quite a ways off to think we won't be tethered to the LAN.\u201dAnd another reader says the size of your bandwidth does matter:\u201cWhile there isn't a big push or need for gigabit to the desktop most users can tell the difference between performance at 10M bit\/sec vs. 100M bit\/sec and will obviously prefer the latter. Desktop and laptop systems come with 100M standard and many will soon have gig. If you are going to get it anyway on your workstation, why settle for 54M bit\/sec?\u201dSome argued that problems could be overcome. As one reader wrote: \u201cThe vendors will solve\/minimize the problems we see currently. Their success and even survival are at stake.\u201dBut in the next breath, a caveat:\u201cThe growth will not be very fast in traditional office environments. Most already have substantial wired infrastructure and will hang onto that for a long time. This has already hurt the vendors like Cisco, Nortel, et al, who are not convincing many people of a need to upgrade existing network hardware. Best chances for growth are probably in newly built offices, niches in offices such as conference\/training rooms, schools, and home.\u201dThis reader saw a specific application for wires:\u201cThe most powerful argument for copper connections in the future will be power over Ethernet, and I believe it will be this combination of wired and wireless that drives our industry very soon.\u201dInterestingly, at least a couple of readers were inspired by my musings to extrapolate further:\u201cWhat if the IEEE folks would pick up the emerging Ultra WideBand (UWB) technology and define yet another physical layer for good old Ethernet? They did it before with 10M, 100M, 1,000M and 10,000M bit\/sec interfaces over coax, copper and fiber-optic media. So why not extend that success story with some wireless chapters?\u201dAnd I\u2019d like to close with this reader\u2019s thoughts on WLANs, the universe, and everything:\u201cThinking about the evolution of wire to wireless I am reminded of the greater communication network of the Universe. All objects (including humans) communicate via wired medium within themselves, and via wireless medium to other objects.\u00a0\u201cFrom speech, body language and impressions, to gravity, strong & weak nuclear forces and electromagnetic force, the infinite capacity of wireless communication medium of our Universe drives the process of Life\u2026\u201cTherefore going wireless is not an option, it is the destiny.\u201dBig thanks to everyone who took the time to write in.
