Software Defined Radios (SDRs) allow operators and service providers to provide alternative equipment testing methods to the traditional heavy scanners and tests currently conducted in the field. SDRs open an opportunity to low-cost options of not just scanning predefined networks, but quickly finding competitor networks, bandwidths, and use configurations with open source stacks and crowd funded hardware.
DAS systems are an effective way of adding coverage and capacity and have become an integral part of a wireless network to provide an effective solution in challenging RF environment. DAS solution deployed in various environments requires Optimization of the network in order to meet network performance requirements and excellent customer experience.
To assign PCI correctly and efficiently will increase resource utilization and QoS of the LTE system for subscribers. Poor planning results in PCI conflicts or collisions which impact network performance. TTS Inc developed the PCI/RSI Audit and Adhoc planner functionality within the IMNOS platform providing speedy, accurate, and immediate results. This modules improves performance and adds engineering efficiency.
The recent announcement by Uber to release anonymized data for over 2 billion trips to improve urban planning through the Uber Movement site could also improve what Uber relies on the most, wireless networks. The greatest challenge to mobile wireless network is simply mobility.
When doing any indoor small cell design, it is important to understand that every building is different. These physical difference need to be accounted for in the design. There are many soft RF considerations as well, however we will focus on the physical considerations here.
Low band spectrum (400, 700, 800, 900MHz) provides clear improvement to network coverage over high band spectrum (1800, 1900, 2100, 2600MHz) for wireless networks. Low band spectrum can give twice the coverage radius of a high band site while at the same time providing 6-10dB improved signal strength at the same point.
For a single event like Super Bowl, a stadium may have over a terabyte of data passing through the serving cells. Building and optimization of a DAS is a challenging process which requires equipment validation, DAS configuration adjustments, surrounding network interference mitigation, RAN network parameter optimization, and neighbour and Layer management optimization to support heavily loaded conditions.
With all the talk of 3G/4G/5G wireless networks and the speeds they provide, the question really comes down to how much speed is enough? With mobile network operators (MNOs) data caps limiting overall data utilized, faster speeds really just mean reaching the limit faster
In any industry, there is continual progress made towards employee safety and overall process efficiency. Technological advances often help in achieving this goal. Unmanned small aircraft or drones could be considered one of these new tools for wireless network engineering and operations.
To maximize the use of spectrum, a mix of footprint optimization or RF shaping is required in conjunction with parameter tuning and feature optimization. Cluster/Area optimization of a LTE and 3G network with macro and oDAS layers requires a complete cell footprint view in order to effectively optimize and maintain performance in a mature wireless network.
Indoor small cells are typically installed in venues to fill in small coverage holes to provide better voice quality, data throughput speeds and reduced drop calls at a very low Installation cost compared to a conventional DAS system. As with any other wireless system small cells have to be carefully designed, installed and optimized to provide optimum coverage and quality to end users.
Mobile Network Operators (MNOs) are slated to begin massive 5G upgrades in parallel to existing LTE expansions. These capital expenditures tend to leave large impacts on the existing customer base through network outages, degraded performance, and physical mis-configuration from the work done at each node location. Many times the issue not found and addressed for 72+ hours.
RF Drivetest is the old backbone of wireless networks. As geolocation and other lower cost tools attempt to replace the drivetest, it may need to visit what type of drivetest and costs are being saved. Rather than focusing on the cost of drivetest, lets focus on how to get the most efficiency out of the drive data collected.
