I received two broken Tranzeo WLAN antennas last week. One has water inside; you can hear it slosh around. The other had no noticeable outside damage.
After removing the cover and dissabling the case, I removed the board. You can see the noticeable overload damage to the National Semiconductor LM2599S.
A friend of mine alerted to me to a warning about our local newspaper’s website. McAfee Site Advisor gives the following response: When we tested this site we found links to atomakayan.biz, which we found breaches browser security on our test PC.
When Leader News was emailed with the response, they responsed by saying “… I had no right “bad mouthing” their site.”
Even Google gives the following: This site may harm your computer.
The content in Leader News’ website is bad in the begin with; everything is centered justified. You would think journalists would know better.
There has been a lot of coverage about wirless lan (WLAN) technology. Such as greater speeds, and that the enterprise lans are being switched over.
Hold it.
The reasoning behined WLAN has been forgotten. One reason is mobility. Not the kind in the movies where the hero is driving a car at 80mph while hacking into the police station (National Treasure 2). I’m talking about the kind where the typical user takes their laptop or PDA on trips. Mobility is not mobile. What? Check any coffee shop or airport. The user is not moving; just sitting. And with typical battery life not reaching a full days work. You are going to need to plug into the outlet soon.
Another reason for WLAN is easy connections. Yeah right. I’ve seen two antenna 1 foot apart and still not make a connection. Why is it WLAN is more art than science? As far as easy connections go, you don’t have to run cable. Only on the smallest of WLANs.
Now for the twist. My local ISP is Muhlenberg Online and they use a giant form of WLAN to connect their clients. Here at work we have an antenna pointed at the courthouse. The courthouse then uses a backhaul antenna to transmit to the next city where Muhlenberg Online is located. That’s right, completly stationary buildings using wireless transmission. While inside the building, the users are connected by CAT5e cable.
Now it would have been finacially prohibitive to run cable from one city to the next. So wireless worked out great.
Wireless inside a builing is a big if. If the building as an open layout (large open areas). If you don’t want to connect between floors. Wireless specifications are very overrated. That’s why Earthlink pulled out building a huge city wide WLAN.
