Title: Extending an external antenna
Howie said it very well. As someone who
works at a company that engineers coaxial antenna systems, you do NOT want to
run coax 250’. Signal loss and expense are both excellent reasons why
this is not feasible. Also, you will have separate external antenn
Most, if not all, client adaptors are pre-programmed to search for the best
network first by the NIC manufacturer. So when someone turns on their laptop,
the first network a NIC card will scan for is 802.11a, then 802.11g and finally
(sigh) 802.11b.
Good points by all in this topic...
On anoth
People will look back at 802.11b similar as they look back at using a
hub today - yuck. Why buy a hub when a switch offers better performance
at a decent price point?
Same story for 802.11a. It offers better performance simply from the
fact that there is a lot more bandwidth/channels. By the end o

Title: Why 802.11 vs Wi Max or 3G or 4G
A major benefit of 802.11abg is better
interoperability with wireless clients and the wired LAN. I suggest that you
look at mesh networking based on 802.11abg for the outdoor deployment. It
obviously ties back seamlessly into the WLAN and thus the wir

While I stay away from expressing opinions on this forum, I must chime
in with the comment that anyone looking to buy WLSE/WLSM hopefully has a
VERY good reason (I know of none).
Now for the opinion part...The WLSE (management of AP's) and WLSM (layer

Theresa is absolutely correct. Installing wireless only dorms to
students that expect and are used to broadband wired access is not
trivial and requires careful planning and policy setting. A typical

As a side note FYI, you should upgrade your Airespace controllers.
2.2.129 is fairly old (pre Cisco) and you are many bug fixes behind

One suggestion – do you have a
preferred AP vendor? I know in the past I have worked with customers to help
write a RFI or RFP for/with them. The AP vendor of course will want to tailor
the RFI to what they can deliver so you have to be careful, but if you have a
good relationship and they

Yes, you can use directional antennas at
the top of the shaft to blast signal to the elevator, and if needed put a Cisco

other issues to address such as crossing subnets and SSID’s when movin
