Top 5 Reasons to Declutter Your Cell Site with Multi-Band Antennas

dengyoUSA — Sun, 15 Sep 2024 16:02:16 +0000

From the earliest days of the telephone, companies (and the public) have had to deal with cluttered spaces. As the first phone companies competed for customers, they filled the sky above the streets with hundreds and hundreds of phone lines. Needless to say, it wasn’t the best solution, but it was the only solution they had at the time.

Today, those early copper telephone lines have largely been replaced with underground fiber optic cables and wireless technology dominates the communication market. Unfortunately, history tends to repeat itself and instead of cluttered phone lines, we now have to contend with cluttered cell towers filled to capacity with antennas of every make and model.

By utilizing multi-band antennas, you can free yourself from cluttered cell site issues. In fact, here are five reasons why you should declutter your cell site with multi-band antennas.

Cost Effective

Leasing space on a tower can get expensive as the number of antennas you have on site determines your cost. Reduce your monthly costs by replacing multiple single-band antennas with one multi-band antenna that can meet your variable needs and handle multiple spectrums.

Improved Capacity

Space on a cell tower is limited so getting maximum usage is critical for success. With multi-band antennas you can increase your capacity exponentially providing better coverage for your customers.

Reduce Wind Loading

When you have a cell tower in an area known for higher wind speeds, aerodynamics plays a big role in its design and utility. The higher you go, the stronger the wind. Reduce wind loading by reducing the number of panel antenna you have on the tower. With multi-band antennas, you’ll have the same broadcasting capacity with less surface area.

Increased Safety

Tower climbers have a very dangerous job. Suspended high above the ground, they ensure our wireless technology works, keeping us connected no matter where we are. So why make their job more difficult? Fewer antennas mean less equipment for them to deal with when servicing the site decreasing the odds of unfortunate accidents.

Better Aesthetics

A common complaint concerning cluttered cell towers is how unseemly they are. Overflowing with single-band antennas, their patchwork look gives onlookers the impression that planning and aesthetics don’t mean a thing to the cell tower owner. With multi-band antennas, you can reduce the number of antennas and organize them into a much more visually pleasing arrangement that’s still effective for coverage. At DENGYO, we focus on performance quality and clean aesthetics to create wireless technology that performs exceptionally well. By utilizing our variety of multi-band antennas, you can declutter your cell site while still providing the quality coverage your customers expect.

The Paris Olympics is setting a new standard for sustainable events. By using existing venues and focusing on reducing waste, they’re making a big difference. 5G technology is a key part of this effort.

5G is more energy-efficient and requires less physical infrastructure than older networks. This means less power consumption and less environmental impact. Plus, it’s powering amazing new experiences for fans, like live streaming from an athlete’s perspective.

Beyond saving energy, 5G’s flexibility is empowering new and exciting innovations. For example, Equinix is leveraging the heat its data centers generate to warm the Olympic pool. We wonder if anyone’s told the athletes yet that their environment is, in some significant ways, being powered by the data center industry! It’s a beautiful example of how technology can help empower multiple sustainability goals at the same time. Orange and Cisco’s collaboration on a private 5G network will deliver immersive live streaming experiences, while Intel’s advanced CPUs will power AI workloads and virtual reality applications, enhancing spectator engagement without compromising on environmental responsibility.

Design Your Own Custom Antenna

dengyoUSA — Sun, 15 Sep 2024 15:20:21 +0000

Go to Custom Antennas

In the world of RF, there is no such thing as a one-size-fits-all antenna. A stadium antenna is designed for capacity and a restricted coverage area, while a macro base station antenna may be optimized for high gain and requires RET (remote electrical tilt) functionality. Some sites require concealment or must comply with strict building codes or municipal by-laws.

You don’t have to be an RF engineer to design an antenna. At DENGYO, our core competency is in designing and manufacturing quality antennas. We do the heavy lifting so that you can focus on the key performance specifications. Let’s look at some of the key parameters that can be specified when designing a custom antenna.

Base Station Antenna customization options

Frequency Bands
Multi-band antennas serve multiple frequency bands with a single antenna and minimizes footprint. An operator’s spectrum holdings may vary by area and by frequency, so the combination of frequency bands deployed may vary by area/site. We tailor to the customer bands with antennas that have wide frequency performance at all the popular spectrums from 617 MHz to 6 GHz.
Number of ports
The number of ports on an antenna varies greatly to match both frequency bands and radio configurations. From a simple 2 port antenna for limited spectrum like low band 617-894 MHz with 2×2 radio configuration; to 28 ports at low band, mid band, high band with 2×2 radio configuration; to 4×4 radio configuration or 8×8 radio configuration for MIMO applications where necessary. The number of ports at each frequency will vary to match the radios used for any bands or sub bands within the antenna’s frequency range.
Gain
Gain is typically maximized at the different frequencies, while at the same time each frequency band needs to have the gain provide similar coverage to match the radio. The higher the frequency, the higher the attenuation and hence the shorter the range. Higher frequencies usually require higher gain to reach the cell edge. This however can also be managed by using MIMO configurations that will also increase the effective reach of the signal. The lower the frequency the larger the antenna elements and antenna dimensions will vary depending on the gain needed.
Horizontal Beam Width (HBW)
One method to adjust coverage and capacity is to engineer the radio sites with different HBW antenna configurations. The very popular 65 degree HBW is typically used for a 3 sector site. If an engineer wants to add capacity to same site often they will reduce the HBW to 45 degrees or 33 degrees to add sectors from 4 to 6, or even more, with narrower beam antennas. A narrower HBW typically requires a wider antenna with antenna elements side by side. This allows more radios to be connected and therefore increase capacity at the site. Providing antenna designs to suit the customer needs for HBW is yet another customizable option.
Vertical Beam Width (VBW)
The VBW of the antenna is used to also optimize the coverage area of where the radio signals are transmitted to and received from. A very large vertical beam will spread the signal in a larger area and must be managed carefully. For smaller VBW typically more antenna elements are stacked to reduce the beam which also adds gain. Adjusting the VBW for an antenna is therefore a desirable customization option.
Passive Intermodulation (PIM)
These unwanted PIM signals that can cause problems with signal integrity and impact data rates to and from the mobiles need to be managed very carefully. Minimizing any nonlinear interaction of the signal while being conducted and transmitted by the antenna is critical. The current standards are often revised to higher requirements as new standards evolve for higher data rates from analog to GSM, CDMA, WCDMA, LTE, 5G and higher. We have seen requirements evolve from -150 dBc to -153 dBc to even -159 dBc (using two 20 watt signals).
Remote Electrical Tilt (RET)
This requirement is tied very closely to the radio configuration required. The RET mechanically changes the phase of the different antenna elements so that the antenna beam is adjusted vertically. For each radio configuration, the RET device will allow the adjustment of multiple antenna beams for the radio(s) connected to the associated antenna ports. So having one command to the RET device control two beams for a 2×2 radio configuration or 4×4 or 8×8 is desirable. We provide options for any number of radio configurations.
Size and Weight
The final dimensions of an antenna are always a critical requirement for mobile network operators. Minimizing the antenna’s final size and weight is an important design consideration. Tower loading and wind loading must be managed since most towers will have multiple antennas for each sector and will often have antenna at multiple levels. Making sure the site is physically robust is very important. Also, often for leased towers, operators may have leasing costs that will vary by size and weight.nfiguration.

The Design Process

Our design process is a robust process where all the considerations above (as well as many more) are evaluated against our capabilities and existing designs. The number of antenna elements for gain, HBW, VBW are considered and accounted for. Simulation of the design is the first step to ensure the design is capable. Specifications are then provided with antenna radiation patterns to customer for approval. After simulation the initial engineering units are built and evaluated. Materials are carefully selected for PIM performance along with the other requirements. RET configuration and mechanical design is then completed. After initial engineering build and evaluation small adjustments may be made for final mass productions considerations and performance.

Manufacturing and Testing

During the engineering evaluation documentation is completed so that at the end of engineering evaluation the product is ready for mass production. Testing methods and equipment required to measure compliance are determined so that each product is manufactured and tested the same way each time, to ensure dependable and reliable performance. Each antenna is tested to ensure customer never has an issue and there is test data available for each unit.
