Twin Beam™ Base Station Antennas ─ Offer Offer the same capacity as traditionally crowded towers with twice as many antennas In today’s wireless market, the term “bottlenecking” has come to have meaning. With 3G, 4G, and LTE all being utilized at full speed, operators are having difficulties keeping up with the increased network demand on capacity coming from high-speed applications and devices. An example, like the iPhone, is driving a massive increase in demand for wireless bandwidth. While the average smartphone uses <50 megabytes of data per month, iPhone customers are closer to 500MB, and the problem may grow as new devices like the Palm Pre and Motorola Droid offer iPhone-like multimedia experience. They are calling it the “iHog” problem: problem: iPhone subscribers use as much as seven times the network bandwidth of voice users and about twice that of other 3G customers.

With all these issues coming to a head, what do carriers need now more than ever? Capacity. What has the Andrew Base Station Antenna team designed and engineered to handle these crucial capacity issues? issues? The Twin Beam Beam family of antennas. It is estimated that by 2012 there will be more than 1 billion mobile mobile broadband connections. With the fast growing number of consumers using multiple data devices on a global basis: at home, at work, and on the go, capacity rapidly becomes increasingly important. To help co mbat the capacity issue, our engineers have created the HBXX-3817TB-VTM HBXX-3817TB-VTM Twin Beam antenna that is designed with:
•
Two beams from a single antenna at the same width as a standard 33° antenna — 2 x the width of 65° antenna at 12 inches.
Increased gain of the 33° antenna improves in-building penetration.
•
2 X 2 MIMO Ready.
The Andrew Twin Beam antenna uses cutting edge technology to provide robust network performance, fast deployment, and cost effective capacity solutions to support emerging data services and applications. Twin Beam offers the same capacity as traditionally crowded towers with twice as many antennas. Key Benefits Enhances network capacity—six sectors, just three antenna faces Increases flexibility in network optimization with RET Minimizes CAPEX and OPEX by reducing antenna count Maximizes spectrum use, boosting average revenue per user Cuts leasing costs and eases re-zoning restrictions 2 X 2 MIMO ready Back To Back BCCH re-use • • • • • • • •
Key Applications Improve utilization of existing network infrastructure Address needs of high-density markets with limited site capacity Delay addition of CDMA or W-CDMA carriers Optimize data transfer rates for 3G/4G/LTE markets • • • •
There have been several successful Twin Beam antenna trials in India, Taiwan, Canada and the United States. We know Twin Beam antennas are valuable assets to any network where capacity is top priority, now we are ready for everyone to gain this knowledge as well.
