Easy spectrum utilization anywhere in the world, with no interference Millimeter waves operate with highly directional pencil beam antennas, making spectrum utilization simple even when multiple units are deployed in close proximity. Since millimeter waves are a relatively new spectrum, there are significantly lower chances of congestion upon deployment of new links. Where reliable, high-capacity wireless connectivity is needed for multiple Wi-Fi hotspots or multiple streams of HD within security networks; the uncongested interference-free spectrum of millimeter wave technology tops every other. 2. Big connectivity pipes for big cities Big cities utilize a great deal of public Wi-Fi, HD streaming for security networks, business broadband, and crowded mobile networks. These networks are constantly expanding and will most certainly continue to do so. With the constant need for higher throughputs, millimeter wave links, with their multigigabit throughput, offer big connectivity pipes, which meet the needs of these big cities. 3. Speed of deployment matters No construction, no digging, and no stopping of traffic is necessary. To deliver a service, go to the desired location, look for a clear line of sight, and simply set up your wireless link. Site permits will be significantly easier to obtain thanks to the tiny size of Siklu's units. Once these minor preparations have been completed, installation can take as little as 15 minutes. Should you need to connect another customer or cascade devices for network expansion, Siklu's units include a powerful integrated multiple-port Gigabit switch, making them the simplest, most economical, and most reliable approach to service expansions. Millimeter waves are available in two different types of regulation schemes: lightly licensed with low fees and quick registration process and license-free. Either way, spectrum acquisition is simple and fast. Visit www.tessco.com/go/siklu for more information. When considering a new Distributed Antenna System (DAS) or enhancements to an existing ecosystem, what are the critical steps and considerations to ensure your deployment meets current demands and future growth? Building a comprehensive DAS ecosystem requires careful planning and expertise to ensure that cellular, public safety, and wireless signal availability is always on. TESSCO's system architects have outlined the eight critical steps to successfully deploy a new DAS. Step 1: Project Requirements Defining the scope for the project is critical and sticking to it is even more important. Scope creep on either side of the customer/vendor relationship can cripple the outcome. DAS expertise can help carefully define your project requirements. Look for a robust online DAS knowledge center and an experienced technical support staff that can guide every consideration. Step 2: System Design Architecting your DAS requires expert knowledge of technologies and the multitude of manufacturers and solutions on the market. The right partner can guide you through every aspect of system design in order to complete a comprehensive bill of materials (BOM). Hire someone who knows current carrier and public safety requirements, how to manage the contract vehicle, and has the configuration tools to produce system designs that meet your requirements, scope, and budget. Step 3: Project Planning Whether working on fiber or coax or aligning active or passive components, working with a partner with significant deployment experience as well as comprehensive knowledge of system design, architecture, and hardware selection can help reduce risk and ensure a successful outcome. DAS is often used in scenarios where alternate technologies are infeasible due to terrain or zoning challenges. Make sure your partner has the experience necessary to identify unique requirements in each of your facilities. Step 4: Proposal When it's time to bid, your project requirements should be aligned with a comprehensive BOM. It is estimated that 60 percent of costs are dedicated to materials for Multicarrier DAS projects. Along with project documentation, the proposal should meet your project schedule, technical requirements, and budget. Step 5: Carrier Coordination Possibly the most important step in a DAS deployment- coordinating with the carrier-requires two phases. First, find a partner who has worked with all the major wireless carriers and can meet carrier acceptance. Second, work closely with your partner to make sure you are contacting your carrier(s) at the proper time and are providing accurate documentation to support your design. Step 6: Logistics Now that you're ready to implement, having a partner with the supply chain expertise to handle the gathering and delivery of materials is vital. You'll want a partner to provide kitting, pre-assembly of cabling and enclosures, and staging to help meet even the tightest scheduling windows. Gathering, kitting, and integrating efficiently can make or break your deployment schedule. World-class supply chain capabilities keep costs in check and your project on time. Step 7: System Installation & Testing While onsite logistics are part of your installation effort, a high- quality partner will remain connected to the project throughout your testing phase. System monitoring alarms, minimum signal strength, and battery backup are important testing criteria. A partner who works with you at every stage to address scope and scheduling changes, last minute substitutions, and approvals is necessary during this phase. Step 8: Commissioning and Cutover System commissioning is a critical part of the DAS life cycle and is not often given the attention it requires. You know that downtime is not acceptable and your partner should, too. Make sure you have the right test equipment, last-minute site materials, spares and replacements, battery backup for public safety requirements, and other tools and supplies on standby. Now that you know the eight steps to successfully implement a DAS, look for a solutions provider who has the knowledge, re- sources, and scalability to help deliver your deployment on time and on budget.
