October / November 2014 Additional multipliers include the rise of wearable sensors that monitor the human condition in all kinds of ways, connected cars and connected homes, and so-called machine-to-machine (M2M) or Internet of Things (IoT) connectivity. Cisco's VNI report projects that, by 2018, mobile video will account for 69 percent of the total mobile data traffic with mobile web and data accounting for another 12 percent, for a combined 80 percent of the total. Mobile audio, M2M and file sharing comprise the balance. 2. Population projections of 8.1 billion by 2025 are dwarfed by Huawei's CGI estimates of 100 billion connections (both human and machine) in that same year. 3. Huawei also noted that the average Internet user consumes about 16 gigabits or Gb (a billion bytes per person) per month, but by 2015 that number will more than triple to 50 Gb per month. If your eyes have not glazed over at the sheer magnitude of the numbers, consider the infrastructure and spectrum issues that will accompany such growth. The implications for both indoor and outdoor wireless networks are significant. Wireless Carrier Network Upgrades Attend any sporting or entertainment event or any gath- ering to hear or see a popular team, group or individual, and what happens? During the event or the game, audience members hold up their smartphones to re- cord or photograph the event. As soon as it ends, everyone frantically types messages to post the video or pictures on any number of social media to which they subscribe. From the moment those smartphone users hit Send, the carrier network is overloaded with a tidal wave of data. The key question: How do we, as an industry, build a ubiquitous broadband net- work with enough spectrum to handle all of the expected data traffic? RF engineers believe one of the simplest overload relief solutions is to move the an- tennas closer to the devices. While techni- cally correct, actual implementation involves long deployment cycles and big capital expenditures. In fact, work is progressing on ways to enhance data-handling capabilities of the outdoor macrocellular network. New carrier 4G LTE deployments involve remote radio units (RRUs) that are fed by fiber optic cables that significantly reduce RF signal losses compared to coaxial cables used with earlier generation radios. Lower RF signal losses mean stronger signals to mobile devices and faster data speeds. New frequency bands, such as 700 MHz and Advanced Wireless Services (AWS) in 1700/2100 MHz, open up additional spec- trum for 4G LTE applications that support the proliferation of smartphones, tablets and laptops. Future 5G bandwidth needs are being considered with the additions of 600 MHz, AWS-3, 3.5 GHz and 5.9 GHz spectrums. While these bands will provide much needed band- width-handling capac- ity in both licensed and unlicensed frequencies, spectrums take time to develop and are costly for wireless carriers to acquire from the government. Wireless Service Inside Out Moving antennas closer to devices, also referred to as "network densification," is get- ting underway with deployment of cellular small cells and outdoor distributed antenna systems (ODAS). But there is a twist. Studies by major carriers such as AT&T Mobility suggest that nearly 80 percent of all mobile data calls originate or terminate in- side of buildings. Indoor distributed antenna systems (iDAS) in large high-rise buildings or cellular signal boosters for smaller spaces, and even small cells, are now bringing cel- lular signals indoors. For pure mobile data handling, however, Wi-Fi is becoming the wireless technology of choice. Wi-Fi technology available today is a considerable advancement from the first commercially-available version in 1999, and it offers a number of advantages over cellu- lar service in a data-only application. Today's Wi-Fi access points (APs): quency bands that do not require spec- trum or licensing fees. capacity with the latest generation IEEE 802.11ac standard that can support data connections up to 1 Gbps, depending on the number of users. spicuously on walls or ceilings. cable and can be powered via power- over-Ethernet (PoE) feeds.
