How big is this surge and what can carriers do to handle it? Eye-popping Market Projections By now, most industry professionals should be familiar with the robust projections for wireless data growth. These widely-referenced sources can help level-set everyone's understanding: dicts 25 billion wireless devices will be con- nected worldwide by 2015 and 50 billion con- nected by 2020. Overall mobile data traffic is expected to grow to 16 exabytes per month by 2018, nearly an 11-fold increase over 2013 (an exabyte is 10 18 bytes of data - a billion billion bytes). Global mobile data traffic will grow at a compound annual growth rate of 61 percent from 2013 to 2018. Asia-Pacific will account for 42 percent of that growth, while North America represents 19 percent of the global total. projections with mobile data traffic between 2013 and 2019 predicted to grow tenfold to close to 20 exabytes per month by 2019. indicates a total of 100 billion connections (human and machine) by 2025. That figure includes 8 billion smartphones, but 90 percent of those connections would come from intelligent sensors. What Are The Market Drivers? Three factors are driving these numbers: the mix of mobile data traffic, more devices than people and data usage per device. 1.

For several days a professional cellular crew couldn't identify the problem with conventional methods and tools, costing the WISP more than $1,000 a day. It took only a few minutes with SAF's Spectrum Compact to solve the problem. Arbuckle Communications, based in Ardmore, Oklahoma, was founded in 1931. Today Arbuckle is a WISP with an approximately 50-mile wireless network around the city. The company offers high- speed wireless Internet for businesses and households as well as voice services. Five new microwave links were installed during Arbuckle's network upgrade. The installation crew detected a problem with an 11GHz 17-mile link with four-foot antennas where the radio signal was 30dB off of the target level. Conventional radio alignment tools and methods failed to explain the insufficient signal strength. After several attempts to align the antennas using a voltmeter, the problem still persisted, even after reaching the maximum level on the device. Besides, the voltmeter measurements were influenced by unwanted emissions, distorting the readings. It became apparent that conventional radio alignment tools and methods couldn't identify the cause of the problem, thus threatening to significantly delay the commissioning of the network and increasing the WISP's expenses. After many unsuccessful attempts to identify the problem, Arbuckle was offered to do the link troubleshooting with the Spectrum Compact. The cause of the problem was detected in less than 10 minutes. The engineer on the ground simply attached a waveguide flange to the Spectrum Compact unit and pointed it in the direction (along the path) of the transmitting radio. Spectrum Compact indicated that the transmitting radio " It became apparent that conventional radio alignment tools and methods couldn't identify the cause of the problem, thus threatening to significantly delay the commissioning of the network and increasing the WISP's expenses.''
