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.
Engineering discussions tend to focus on how to improve the KPIs in the sense of network quality, reduce drops, improve accessibility, etc. Fixing coverage holes is always noted, but this tends to be fixing coverage the “right” way, which is typically the long term capital improvement. Long term network fixes come through large scale site build, low-band spectrum acquisition, improved hardware deployment, or alternative network types which is typically large capital expenditures
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.
The advent of low cost operators and MVNOs in the past few years has put enormous pressure on Mobile Network Operators (MNOs) to reassess their conventional capital expenditure strategies to provide enhanced network quality and retain constantly eroding margins for the best possible ROI. MNOs have reacted to this trend by adjusting their offer mix to maintain average revenue per user (ARPU) levels and their marketing efforts to optimize their cost basis. It has become all the more important now for MNOs to consider the cost optimization opportunities relating to daily “build and run” activities.
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
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.
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.
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.
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.
The visualization of social media data provides insights into a highly mobile segment of the population. Knowing where people typically post and that the typical geotagged posts with GPS are from mobile devices provides insight into where MNOs need to have the best network to serve them.
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.
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.
