1 Dual-Band Antenna vs. 2 Single-Band Antennas

Hey guys-
I was wondering if I was going to implement a 2504 with a 1550 series AP, would it be better to go with 2 Single-Band Antennas or 1 Dual-Band Antenna (which would mean I'd have to change the AP from an EU to an E).
What is the difference? I am thinking it has something to do with MIMO, correct?
This will basically be used to provided wireless connectivity outdoors to a single user. I am unsure what the NIC specs will be for the client, but I am saying its safe to say 2.4. Although the fact that I do not know, is what is making me purchase support for both bands.

Well it depends on what you are wanting to do. With the EU, you have 6 eternal antennas one for each radio. Now if you have a long backhaul and the omni's will not be adequate for that, then you use the EU with external patch antenna. So that is really the difference, the EU allows you to have a separate antenna type for each band.
Cisco Aironet 1552E/1552EU External Antenna Access Points
The Cisco Aironet 1552E/1552EU Outdoor Access Points are the standard models, dual-radio system with external antenna ports that are compliant with IEEE 802.11b/g/n standards (2.4 GHz) and 802.11a/n (5-GHz). The 1552E has three external antenna connections for dual-band omni or directional antennas. The 1552EU has six external antenna connections, three for 2.4 GHz and three for 5 GHz antennas, that support omni or directional antennas. They have Ethernet and fiber Small Form-Factor Pluggable (SFP) backhaul options, along with the option of a battery backup. These models also have a PoE-out port that can power a video surveillance camera or other devices. Highly flexible models, the Cisco Aironet 1552E/1552EU are well equipped for municipal and campus deployments, video surveillance applications, mining environments, and data offload.

Can you install a single band antenna on dual band ap connectors

Hello,
just a question, what happens if you install single band antennas onto dual band ap connectors, would it work?
greets
J.

It is not only possible its actually one of the ways to use some of the antennas released for 1552-series. There are antennas that are released for the use with only single band while 1552E has a dual-band antenna feeder.

Is the New MacBook Air Wifi N Dual-Band or Single-Band?

Is the New MacBook Air Wifi N Dual-Band or Single-Band? I cannot find any official information regarding this.
I have a Dual-Band router up to 450+450 and I'd like to know if the Mac would make the most of what I have.
Another related question would be… if the MacBook's Wifi could take up to 450mbs or would it only reach up to 300mbs?
Thank you!

Thank you Captfred for the quick clarification. A related question (and this might be obvious, I'm not sure) would be if the MBA uses single or dual antenna? I am not sure if N technologies always use dual antenna by default? The reason why I'd like to understand this is because I do watch quite a bit of streaming video. I supposed streaming through a single antenna could clog the connection quite a bit if at the same time I'm browsing other websites or download something else at the same time? While having two antennas would ease the communication by sending a request through one antenna and receiving the response through the other?
Best,
M

Single 2.4g vs dual band

what are pros and cons of going with a high density 2.4g vs a dual band antenna?

I don't know if you should consider a 2.4 GHz design for any HD deployment. There simply isn't enough spectrum to properly service the depth of clients and there is no 40 Mhz 802.11n or 802.11ac on 2.4 GHz. You really limit yourself with 3 non overlapping channels.
Hope this helps ..

3 x Dual-band antennas vs 6 uni-band antennas

Hello guys,
Could you give me an explanation, what is the main reason? Why it is better to use 3 x 2.4/5GHz dual-band antennas versus 6 uni-band antennas ( I mean 3x 2.4 GHz and 3 x 5GHz) ?
Or maybe I'm wrong?

Ohhhh ... You're talking about the G2 WAPs.
Yes. Dual band antennas is a no-brainer because you don't want to make your WAP look like a porcupine.
Choosing between individual antennas and a multi-band antenna will depend entirely on how you want to use the WAP. For low-gain antenna, you can use rubber ducks/duckies/ducklings but with slightly higher gain antennas, I'd prefer to use a patch antenna.
The diversity of the 802.11ac patch antennas will depend on the growth (in sales) of the WAPs themselves. Most of the antennas come from manufacturers like Terrawave so if you need a patch antenna and Cisco doesn't have them, check out Terrawave and you'll probably find some there.

Dual-band Omni External Antenna

Hello,
Can someone recommend me a dual-band omni antenna for connection to a Cisco 3600? For use indoors.
I have found this:
http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2544v4m-r.html
But it seems a bit overkill for what I need. All I want is a small profile indoor antenna I can connect to the AP.
I require the antenna so that the AP can be mounted vertically with the antenna sticking out the top so as to create the correct coverage pattern
Thanks

Hi Kashif,
This document link you've posted is already OUTDATED. All the antenna's in this PDF are valid up to the AP1250. The antenna required for the 3600, as what is stated by the OP, is totally different.
Antennas for the newer generation of Cisco APs which are dual-band radios, go here.

Replace Spectre 13 x2 13t-h200 single band wireless network adaptor with a dual band adaptor

What is the path taken to upgrade the installed single band wireless network card with a dual band card.

Hi rb1950, and welcome to the HP Forums!
I understand that you would like the 'How to' information on changing your single band wireless card for a dual band wireless card. To better guide you, could you please tell me the model number of your computer and the operating system that is running on it. Here are some guides for How Do I Find My Model Number or Product Number? and for Which Windows operating system am I running?.
Please let me know and I will try my best to find the information you need.
Thank you and have a great day!
I worked on behalf of HP.

1600/2600e AP mesh/bridge with dual band antennas

Has anyone setup a 1600/2600 as a wireless mesh/bridge with the dual band antennas? I'm curious to see how well they work with the dual band antennas and how well the 5Ghz backhaul works in conjunction to the 2.4Ghz client side.

Well for outdoor, you need to have the external antennas since the AP's will need to be in an enclosure. You also have to make sure that the temperature doesn't go beyond the data sheet specs for operating temperature conditions. Outdoor MESH AP's is really the way to go as it can be costly to us an indoor AP and retrofit it to be outdoors.
Thanks,
Scott

Can 2nd Gen Express extend dual band or only a single?

Since the new express is simultaneous dual band capable, I assumed I could extend both the 2.4 & 5 GHz bands at the same time. While setting it up I noticed it only allows one netrwork from the Extend drop down box.
Is the simultaneous dual band only for creating a new network and not an option for extending?

Since my Express (and Apple TV) are located a floor above my Extreme, I'm guessing that they'll automatically connect to the 2.4Ghz band since it'll be stronger/better quality signal...?
Yes, that would be a good assumption.
I'm looking to get the best performance to the ATV (hoping for 5GHz) and don't have the luxury of running CAT cable to bridge the 2 routers.
From personal exprience the ONLY way to get stable streaming performance, especially of HD content, is via a Gigabit Ethernet connection between routers. As you surmised, 5GHz wireless would (or should) perform better than 2.4 GHz. If you are "stuck" with the lower frequency band, be sure to eliminate as many other 2.4 GHz signal sources (portable phones, microwave ovens, baby monitors, etc.) as possible to achieve the best bandwidth for streaming.

Using a dual band router

I have read messages of people saying they have bought a dual band router. They use that instead of the actiontec for their wifi. The secondary router gives them better performance. Is this a good idea or a waste of money?

It would appear you have the dual antenna N band capable Actiontec MI424WR. This router will provide good signal strength in most dwellings and and will be twice as fast as a single antenna Actiontec B/G band router. I wonder if the folks who recommended an upgrade are doing so based on the performance of Actiontec routers of the same part number but with a single antenna and B/G band connectivity.

Simultaneous Dual Band AP?

I'm not terribly familiar with cisco's WAPs outside the small business models and I'm trying to find an "inexpensive" autonomous AP that supports 802.11n, simultaneous dual band, and internal antenna. Are there any comparison charts showing which access points support simultaneous dual band?
Thanks!

I see where it says that it 2.4 and 5.0 radios, but not that they can both be in use at the same time. Are all of the non-small business APs with dual radios capable of working on both frequencies at the same time?
Said who??? Single- or Dual-band radios work simultaneously. It doesn't make any logical sense if they don't.

How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?

How can I get Wireless N 5MHZ Capabilities Dual Band up to 300MHZ on my DV7 Laptop?
Question for 4/18 experts ...
Or specifically, how can I replace my wireless card on a DV7-6B32US and upgrade to Intel Centrino 6230?
I have a relatively new DV7-6B32US puchased on 11/2011. Still under warranty. purchased 2 of the laptops. (also own 3 hp desktops and 1 HP All in One)
Existing card is wireless N but does not support 5GHZ or dual band. It is Broadcom 4313 wifi card and I am just realizing that the Broadcom card does not do the dual band 5GHZ wireless N. I have Linksys e4200 router which supports 5GHZ and dual band speeds up to 300 Mbps.
I called tech support and with their help identified Intel Centrino 6230 as the correct upgrade, and with their help ordered 631956-001. In the Maintenance Manual for DV7 laptop, this part number was listed for Intel Centrino 6230. Turns out HP sends an Intel Wireless N 1030 card, which is no better than my existing card. I called HP and they acknowledged that some manuals use part number 631956-001 for Centrino 6230 and some use 631956-001 for INtel 1030. So HP support said they would give refund but case manager was of no help in solving the upgrade problem. Said it was unavailable but here is your money back.
So after more searching, I see others have used part number 636672-001 to order Intel Centrino 6230, specifically for HP ProBook 4530s, 4230s, 4730s. And if I use part number 636672-001 and go thru parts store at HP, I can purchase it.
But will it work??
First, will the Intel Centrino 6230 with part number 636672-001 from HP parts, work in my HP DV7-6B32US, even though the part number is NOT listed in the Maintenance and Service Guide for my specific laptop. I see postings about whitelists and changing bios, etc, and am hoping someone can provide some guidance. I have been thru 2 tech support calls and one case manager and have gotten 3 different feedback from HP, from yes it will work and ordering the part, to buy it on amazon, to it will not work and here is your money back.
Second, I see some postings about Centrino 6230 and multiple antenna's. When I replaced the Broadcom 4313 with the Intel 1030 card, I simply unattached 2 wires and reattached the wires. And it worked. I am wondering if the reason HP doesn't list the 6230 card for DV7 is that DV7 does not have the antennas required to support 6230. Does the Centrino 6230 require 3 antennas?
Thanks for any suggestions. The existing cards do work but I paid extra for the Linksys e4200 Router and just assumed a winter 2011 $700 laptop from HP would use the latest wireless n technology, otherwise I would just keep existing cards.

I have went thru the exact same problems trying to upgrade the wireless card in my DV7. It is very frustrating that the wireless card can't be upgrade to one that supports 5Ghz. Here is my post from the network forum. http://h30434.www3.hp.com/t5/Wireless-Internet-Home/Unsupported-Wireless-LAN-6230/td-p/1419595 Doesn't sound like it is possible to upgrade to the Centrino 6230 without it being added the the "white list". Sound like HP doesn't update the list after shipping the notebook. I feel your pain. HP needs to help out the consumer in upgrading the wireless cards. I see we are not the only ones that have had this problem.

How to set-up a DUAL BAND wireless network.

Lots of people are reporting problems caused by replacing an existing wireless network with the new Airport Extreme 802.11n base station.
* Xbox360 compatibility.
* Airtunes issues
* 802.11n slowed down by 802.11g devices
One workaround is to set-up a dual-band network. Your old 802.11g base station looks after the older "g" devices. And the new Airport Extreme looks after the 802.11n devices.
There are a number of benefits to this solution.
* Everything that did work, carries on working. No reconfiguring needed.
* Everything works at its fastest possible speed. You can use the full 270Mb 5Ghz band for n devices.
* 802.11g traffic does not interfere with 802.11n traffic at all.
* It's easy to set up.
The downside is
* There are two boxes. I want one.
This is the diagram (again)
Note that in this configuration, the new Airport Extreme base station is set-up in Bridging Mode.

I've done some testing and here are my findings:
- 2 Computers, 1 C2D N enabled and iMac G only in 2 diff rooms
- 2 AX to stream music
- Transfer of a 446 Mb avi file from Airdisk to C2D
- 2 Wifi Networks: 1) G only from a Netopia 2) Depending from settings from AE(n), Both Base Station are placed aside. When G network is available both AX are connected.
- With or No airtunes means a stream to the 2 AX from iMac while transferring the 446 Mb file to the C2D.
446 MB / AE(n) 5 Ghz N / No Airtunes / Netopia Off / 2:47
446 MB / AE(n) 2.4 Ghz N Only / Auto Ch / No Airtunes / Netopia Off / 2:13
446 MB / AE(n) 5 Ghz N / No Airtunes / Netopia On / 3:14
446 MB / AE(n) 5 Ghz N / With Airtunes / Netopia On / 3:20
446 MB / AE(n) 2.4 Ghz N Only / Auto Ch/ No Airtunes / Netopia On / 2:29
446 MB / AE(n) 2.4 Ghz N Only / Auto Ch / With Airt / Netopia On / Unusable
446 MB / AE(n) 2.4 Ghz Mixed / Auto Ch / No Airtunes / Netopia Off / 2:17
446 MB / AE(n) 2.4 Ghz Mixed / Auto Ch / With Airtunes / Netopia Off / 3:03
Here are the findings:
- Without any G network (meaning no Airtunes possible) the 2.4 Ghz N Only performs much better than the 5 Ghz N
- While streaming Music the 2.4 Ghz Mixed performs better then the 5 Ghz N (Dual Band Network)!
These are my findings with my settings, it could be different, but I'm pretty sure you will find the same behavior on your side. And BTW, the theoretical thru-put means nothing, only real life usage testing is worth something. So on my side I'm going for a single mixed network.
Hope this sheds light for some of you.

Can you add new AirPort Express Base Station Simultaneous dual-band 802.11n with a 1st Gen time capsule network

Hi
Has anyone tried using the AirPort Express Base Station with a first generation Time Capsule and used it to extend their network, while still being able to use the Simultaneous dual-band 802.11n on their network?
Thanks in advance

The first generation Time Capsule was not a simultaneous dual band device.
If you add the "new" AirPort Express to the network and configure it to "Extend a wireless network", it will extend the one single band signal that it is receiving from the Time Capsule.
In other words, the AirPort Express will not extend simultaneous dual bands in this type of setup...since it can only "extend" what it receives. You would need a simultaneous dual band Time Capsule if you want that type of functionality.

What dual band wifi adapter for HP ENVY x360 15-u205na

What dual band wifi adapter is compabible with the HP ENVY x360 15-u205na please. It is somewhat disappointing that a current laptop is still only single band 2.4Ghz, if I had known before purchasing the HP it would certainly have changed my purchase decision.

Hi,
This is an Intel based laptop so you can use Intel 6235 or 7260AC I guess. Go for the 6235. It's a decent wireless card..
