One of the problems I have with many of the wireless specifications is that they are often asked to operate in environments that they don't belong.
One of the problems I have with many of the wireless specifications is that they are often asked to operate in environments that they don't belong. For example, Bluetooth was originally intended to be a simple cable replacement. I can't even begin to name all the places people are trying to shoe-horn in a Bluetooth connection.
Another example is WiMAX in the home. The first question that comes to my lips is, Why? We already have a super-charged flavor of Wi-Fi with 802.11n (or what some people mistakenly refer to as MIMO), while UWB is peering around the corner.
Speaking of UWB, do I really need this protocol embedded in my mobile phone? Nobody has given me a good reason why yet.
The latest interesting move in this area is the push for Wi-Fi in the air, or in the airplane to be precise. This one actually makes sense. It's already in use on some of the international carriers. Let's just hope there aren't any rogue systems trying to communicate with the plane's equipment.
