Wireless network application in hotel, making use of electrical ring main also, need advice please

Posted on 2007-10-02

I am going to install a wireless network in a hotel. It was built in the 1400s so has very thick walls etc.
I have tried a Netgear ANT2409 antenna with a Netgear DG834G wireless router but the wireless network reach is not far enough. My plan is to use a second Netgear ANT2409 antenna and connect it in the following way:
Existing antenna attached to router, router connected to wall-plugged ethernet bridge
Other side of building, wall-plugged ethernet bridge connected to wireless access point with the other antenna attached to it.
Is this a good way to go? Does anyone have any advice? Is it wise to make use of the electrical ring main in this way?
Thanks very much

    I cannot comment on whether using an AC Mains (line power) ethernet transmission device is good practice or not, but one thing I have encountered with AC line transmitters is that if they are on different circuits or diffferent sides of the AC power coming in, the signal dies.

    If you have 240 VAC coming in and have 120 on either side of ground, these transmission devices need to stay on the same side of the AC line. I have read that you can take an industrial rated capacitor (I cannot recall its value) and place it between each side of 120 to bridge them, but that  is not a good practice. (Cap shorts, whewee look out!)

    But if AC mains transmission devices work in your limited environment then by all means, go for it.

    IMHO though, wired is the best way. You cannot run Cat5 to that location? Do you have an unused pair of telephone wires. Patton and BlackBox make copper ethernet extenders, Patton Model 2158/120-2PK, that you can use which would be my second choice. We use them here at my work and they work very well.

    Lastly, another way would be to repeat the wireless signal. The speed decreases on each hop, but usually it is still faster than the Internet speeds we see. I am assuming that this is for wireless guest access to the Internet? I do not know if thos NetGear APs will do a repeater/access point mode usually "WDS with AP" or something similar. We use in our hotel the D-Link DWL-3200. We have placed one about every 75 feet.

    Anyway, I hope I helped.
