We'll have, VoIP, Video and data.

Do you have any recommendation ?.

Re: Wireless Equipment for 1 or 2 Km.

First question would be if you have line-of-site between the two sites.

Yes, we have, It's clear.

Re: Wireless Equipment for 1 or 2 Km.

First, you can probably use 1242 APs with patch antennas, but if the distance is more than 1km, it will probably not work.

Next is a 1300 series with an integrated antenna. Before selecting this bridge, I would suggest you make sure that there is little or no interference in the 2.4 GHz range at both of your locations (Has only G radio). AIR-BR1310G-A-K9 part number.

Last and best, are the 1400 series with an integrated antenna, we have had no issues with those running at 8 miles. (54mbps 28dBi dish). AIR-BR1410A-A-K9 part number. This is a 5.8 GHz bridge.

For either 1300 or 1400, make sure to order proper length power injector cables and any other accessories:

Also, check out the calculator utility:

Thank you by your support.

I checked with a GPS the distance today, It's 4Km, I can see some anntenas so, on that place, I'll scan the RF with an analizer for knowing what frequency I can use.

If I use 2.4 frecuency I should work with 1300, If I use 5 frecuency I should work with 1400, It's Ok ?.

Correct, 1300 series bridges operate in the 2.4 GHz range (only one radio), 1400 series bridges operate in the 5.8 GHz UNII-3 range, also only one radio.

Hi Vlad,

Do you know the best distance(54Mbps)than I can get with this 1410 equipment ?.

Aironet 1410 Wireless Bridge with 22.5 dBi Antenna, FCC Cnfg

Thank you.

Take a look at the distance calculator tool that I have previously posted.

http://www.cisco.com/en/US/prod/collateral/wireless/ps5679/ps5861/prod_technical_reference0900aecd800f9155.xls

It takes multiple factors in to consideration and spits out an approximation of the best distance you will get.

Hi Vlad,

Do you know how I can check the Power level, what level I can use on theses 1400 bridges ?.

How can i check it in IOS software ?.

Thank you.

Re: Wireless Equipment for 1 or 2 Km.

This article will show you how to adjust power levels for the 1400s

http://www.cisco.com/en/US/docs/wireless/bridge/1400/12.3_8_JA/configuration/guide/p38rf.html#wp1017196

Maximum transmit power for point-to-point setup is 250mW or 24dBm (Cisco equipment) in FCC domain. Just to mention that this is the power at the transmitter, not EIRP at the antenna, which can be up to 51 dBi with parabolic antennas, I think.

Thank you !.

It's Ok. I'll put theses briges on two towers that have 15 meters, so I understand that the bridge will be on the top of these towers, do I need another kind of protection for them or the brige are ready for working under rain, sun ?.

Re: Wireless Equipment for 1 or 2 Km.

The unit consists of 2 parts, the power injector and the radio itself. The power injector needs to be indoors or NEMA enclosure. If it's indoors, you can run a power injector cable to the radio, up to 100'. This link http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008022b11b_ps5279_Products_Data_Sheet.html has the part information you need for the injector cable AIR-CAB100DRG6-F. The radio with the integrated antenna, is capable of withstanding weather extremes, you still need to check out the specs to make sure it works in your area.

Re: Wireless Equipment for 1 or 2 Km.

Ok.

I see that power injector has RJ-45 and F-type

connectors, do you know If i can replace it, for installing another power injector with two RJ-45 connectors ?, Can i do it ?.

Because, the distance and power doesn't allow me to use it.

Thank you !.
