Dual Band Mobile Antennas or Broadband Mobile Antennas…which style do you need for today's wireless networks?
It wasn't so long ago that we were excited at the notion that our wireless devices operated on not just one, but two different frequency bands.
As an Antenna Manufacturer, this meant that we needed to introduce dual band mobile antennas that would allow users to achieve optimal communications on both the US Cellular AMPS band at 850 MHz and the new US Digital PCS band at 1900 MHz. It was no small feat to be able to combine operations on each band in the dual band mobile antenna. Special care had to be taken to make sure that signals on the two bands did not interfere with each other.
The next challenge came when cellular users wanted equipment that operated in both the US and Europe. The demand for dual band mobile antennas became a demand for quad band mobile antennas. It was no longer sufficient to cover just the 850 & 1900 MHz band as would be necessary for a US dual band mobile antennas, it was now desirable to cover the US bands and the European bands… in effect combining a dual band mobile antenna for the US market with a dual band mobile antenna for the European market so that 850 & 1900 MHz were covered for the US and 925 & 1800 MHz were covered for Europe. The unit might be used in only one country but the ability to have a single inventory made quad band models a viable option.
A growing number of handheld phones as well as cellular modems for commercial use were entering the market. Some were entirely self-contained, but others were designed to take advantage of accessories that would enhance the device's performance. For consumer use, hands-free car kits were introduced. These devices consisted of a coupling device in the car into which the phone was attached. The signal from the phone then traveled by cable to an external quad band or dual band mobile antenna. The presence of the external antenna provided a clearer signal which improved the user's experience.
On the commercial side, cellular modems were developed for more strictly data applications. These modems were used to transmit critical data, often from remote locations. Cellular phones were notorious for dropping calls and therefore the cellular modems were designed to minimize this risk since the data they were transmitting was generally time sensitive and critical. These cellular modems were almost always attached to externally quad band or dual band mobile antennas to ensure a stronger signal.
In the last few years the wireless markets have become even more complex. With the growing demand for bandwidth and wireless capacity, additional spectrum has been released for auction. In the US, auctions have been held for three significant swatches of spectrum. Specifically, auctions were held for the AWS 1.7 & 2.1 GHz bands, the 700 MHz band, and the 2.5-2.7 GHz band.
It has been interesting to watch these markets roll out. A number of carriers/operators who have been using the 850 & 1900 MHz bands won spectrum in some of these bands. As a result, different carriers have access to different pieces of the new wireless puzzle.
In the past, all of the Cellular Carriers had access to the same bands of spectrum at 850 & 1900 MHz. Phones, radios and dual band mobile antennas that worked for one Carrier would work for all the Carriers.
But today, different Carriers own or have access to different spectrum. AT&T for example, has access to 700 MHz as well as 850 & 1900 MHz. T-Mobile, the company that AT&T hopes to acquire, has access to the AWS spectrum at 1.7 & 2.1 GHz as well as to the traditional cellular bands at 850 & 1900 MHz. Sprint/Clearwire has access to 2.5-2.7 GHz as well as 850 & 1900 MHz. These are just three operators; there are many others that also have a mix of spectrum in their hip pocket.
There is a lot of buzz in the industry about new systems and new speeds, so we know that these companies are activity rolling out new systems. Which raises the question: is there still a role for the dual band mobile antennas? The answer in a nutshell: maybe.
An increasing large variety of wireless applications are springing up in markets that have traditionally been hard wired. From Smart meters to Vending machines to Video games, creative market leaders are figuring out way to use wireless to gain a market edge.
Taking wireless from concept to practice involves hardware, software and a communication channel; different aspects but all intertwined. There is no one combination that will work for all applications. Some companies will have narrowly defined data transmission demands. For example, remote monitoring stations may only need to transmit a small amount of data at any one time. The network designer for these networks may opt for modems that operate only on the established cellular bands at 850 & 1900 MHz bands. A dual band mobile antenna, such as the Mobile Mark RM-900/1900, can easily be modified to serve as a reliable communication point for this kind of fixed monitoring point.
Other companies will have massive amounts of data to transmit and will need the broadband capacity that is only possible with the newest cellular technologies. These technologies are often identified by the protocol such as 4G, LTE, HSPA+ or WiMAX. These newer technologies may operate on a variety of frequency bands. Further, the specific bands used may very well vary by geography and operator. The cellular modem may transmit on HSPA+ at 850 MHz in one community and then on LTE 700 MHz in another.
For companies who need to transmit large quantities of data, a dual band mobile antennas will not be optimal. These companies may need a broadband antenna that can operate on multiple frequencies, drawing from the established 850 & 1900 MHz cellular bands to the new LTE bands at 700 MHz, the new 4G AWS bands at 1.7 & 2.1 GHz or the new WiMAX bands at 2.5 GHz. These companies will benefit from a broadband antenna, such as the Mobile Mark RM-WLF-1C, that can operate efficiently from 694-894 MHz and from 1.7-2.7 GHz.
It is pretty exciting to see how the wireless networks have evolved over time. There are so many more options today than even a few years ago. But it is important to match the application with the correct level of technology. Even today there are many applications that will be well served with dual band modems rather than broadband modems. From an antenna manufacturer's perspective, we will continue to support customers with both dual band mobile antennas and broadband mobile antennas.

Customer Reviews
I bought this router due to being a tech junkie, and the desire to have a router that can transfer files to my home server via my laptop at lightning speed. Netgear WNDR4000 is a part of the first bunch of WiFi routers to support 3-dimensional (data) streams (max 450 Mbps bandwidth) at 5 GHz band. I would say that the router provides a solid connection (no dropouts .... yet .. my old Linksys WRT610N had this problem), slightly higher throughput for file transfers so my Netgear WNDR3700 at 5 GHz band, easy to setup and great parental control feature.
The negative side of the router is that the 2.4 GHz band has only 2 spatial streams to a maximum data link rate of 300 Mbps. Compare the throughput of the 5 GHz band between WNDR3700 WNDR4000 and showed only a 15% gain instead of the expected 50% gain (300 Mbps vs. 450 Mbps).
I also have Cisco E4200, a second router with 3 spatial streams at 5 GHz, I try and I would say that it has the same throughput performance as WNDR4000, better setup utility, and no so great parental controls.
Setup:
Inside WNDR4000 box, you get the router, Power Adapter, Ethernet cable, resource CD (documents and "Smart Wizard" application.) Configuring the router is easy, just plug in the power adapter, Ethernet cable to your computer and configure the router.
You have two approaches to configure the router, the classic web interface for people with experience or "Smart Wizard" for people who want an easy approach without getting lost in the details. Web interface for the router setup is the same as the previous model WNDR3700, so it was a breeze to do. Just setup the wireless security, the ports for my network devices, and I was ready to go. My PS3, volcanic, and Windows Home Server had no problems working with the router.
Use of "Smart Guide" program only allows you to put your wireless SSID and security password. For child safety, give the Netgear a separate utility operated by a company called OpenDNS. It allows you to block up to 57 different website categories at different times of day.
Setup Utility (Cisco Connect) to Cisco Router E4200 is slightly better than the Netgear utility. Cisco Connect allows you to configure several functions, such as visiting network, upgrading router firmware, configuration, etc. The key is parental control, you must manually input the site you want to block
Performance:
Want to know if I made the right move in buying the router, I measured the throughput of the 5 GHz band WNDR3700, WNDR4000 and E4200 router. I used the tool "LAN Speed Test" to measure the movement of the laptop in one room of the router to my server on the router's gigabit port. My laptop has Intel 6300 wifi card that supports 3 data stream. The WNDR3700 showed 115 Mbps up and 128 Mbps down WNDR4000 is 134 Mbps up to 140 Mbps down and E4200 showed 129 Mbps up and 148 Mbps down. As you can see from the numbers, the WNDR4000 is around 15% faster than the WNDR3700. At 2.4 GHz band, all routers around the same speed, 60 Mbps up to 70 Mbps down.

Summary:
All in all I am happy with the router. But I'm docking one star from the rating for the router only delivers 2 stream (not 3) for 2.4 GHz band (not sure why they did it, I hope it is not some standard) and for only the small 15% speed increase over the WNDR3700. As these routers just came out, I guess we'll have to wait to see how robust they are (hardware life and firmware issues).
Background:
As at 28 March 2011, the last three wireless router from Netgear is:
WNDR3700v2 aka WNDR37AV - Dual Band Gigabit Router with 300 Mbps max of 2.4 GHz and 5 GHz band.
WNDR3800 - Similar to WNDR37AV, but with the following functions: print server status, Clear Channel Selector and Quick Start, Steady Stream HD.
WNDR4000 - Dual Band Gigabit Router with 300 Mbps max of 2.4 GHz and 450 Mbps max of 5 GHz band. It does not have the extra features on the WNDR3800.
All these routers have a 680 MHz MIPS 32-bit processor, 64 MB RAM, and are based on 802.11n final version.
