  • Hello. This is Keith Ross, director for networking products at BBOX. Glad that you could join us for the webinar. Today we will be discussing mobile wireless networks and enterprise applications. As you know cellular wireless networks support both voice and data services. Today we are going to focus on data services.
    Enterprises continue to use mobile telecom to drive business growth, cut costs and support strategic initiatives. A Gartner 2013 CIO Survey found that mobility is the second-highest priority for CIOs.
    In the webinar today I would like to discuss the evolution from 3G to 4G in terms of speeds, coverage, and range. I have some information about M2M data plan rates that I think you will find interesting. Next, I will discuss wireless network use cases for oil and gas, construction sites, building automation, and mobile data networks such as point of sale kiosks. Finally, I have some information about Black Box’s new WRT4000 series industrial wireless routers.
  • Mobile wireless or cellular wireless networks are designed for WAN or Internet connectivity for city-wide/national/global coverage areas and seamless mobility from one base station to another. Cellular network technologies are often split into 2G/3G/4G or second generation thru forth generation networks. The chart gives you some information about the radio technology and typical speeds.
    3G technologies include EVDO and UMTS. Each of these technologies specify peak downlink and uplink speeds. For example, EVDO revA supports 3.1Mbps peak downlink and 1.8Mbps peak uplink. Typical or average throughput is about 500-700 Kbps.
    3.5G UMTS HSDPA offers peak downlink speeds of 14 Mbps with 5 Mbps peak uplink. Typical downlink throughput is about 2Mbps.
    4G networks provide even higher bitrates. The current 4G systems that are deployed widely are HSPA+, LTE and WIMAX.
    4G LTE is quoted in wikipedia to support 326Mbps peak downlink with 86Mbps peak uplink speeds. Verizon states that their LTE network supports downloads speeds of 5-12Mbps and uploads speeds of 2-5Mbps with peak downloads speeds of 50Mbps.
    4G has support for cell sizes from tens of meters radius up to 100 km radius. Lower frequency bands can be used in rural areas where 5 km is the optimal cell size. In city and urban areas, higher frequency bands are used to support smaller cell sizes to increase network capacity. In this case, cell sizes may be 1 km or even less. 4G supports at least 200 active data clients in each cell.
    3G and 4G services are available from a number of service providers in the US. A partial list includes Verizon, ATT, Sprint, T-Mobile. The coverage map shows Verizon’s 4G coverage for the US.
  • Let’s talk about a few applications for wireless networks. Wireless networks can be used for M2M or machine to machine communications. A related term is SCADA or supervisory control and data acquisition.
    The oil and gas industry is moving to wireless for well site and pipeline monitoring and control. Operators are collecting performance information such as flow rates, pressure, temperature and equipment status on a 24/7 basis using the wireless network for WAN connectivity. In many cases customers use secure virtual private network connections or VPNs from the remote site to their data center.
    Client benefits include…
    Minimize Downtime: Diagnose potential problems before they have a negative impact, and respond immediately with real-time notification if a failure occurs.
    Improve Efficiency: Monitor machine performance and make real-time adjustments.
    Improved Resource Utilization: Get more out of skilled resources by having the right personnel with the right parts arrive at the right time.
    Maximize Production: Know and react immediately if there's an issue.
    In some cases customers will do their own integration work at the data center to provide users with a web interface for monitor and control functions. In other cases customers work with cloud service providers for managed services and offer smartphone apps, SMS messages, and email alerts, in addition to a web interface.
  • I would like to talk about 2 use cases for wireless connectivity. The first is shown on this diagram. Here the wireless connection to the WAN is the only WAN connection. In the next use case – the wireless connection is a back up connection to the WAN.
    At the heart of the network is the wireless IP router. The router acts as a gateway device between the service provider owned wireless network and the local area M2M network. Just like other enterprise class routers, wireless routers support routing of IP traffic upstream and downstream from one subnet to another and common services such as network address translation, DHCP, and secure virtual private networks. In addition, wireless routers include embedded wireless modems to connect to your wireless carrier. In the US most carriers have a certification process to qualify the modem for use on the carrier’s network.
    The LAN side of the router can connect to Ethernet attached and serial attached devices – in the case of the oil/gas application - these are the flow meters, temperature and pressure sensors, programmable logic controllers.
    End users may need support for legacy fielded devices with serial interfaces such as HMI panels, RTUs and PLCs. So it may be necessary for the wireless router to act as a gateway device for protocols such as modbus.
    Many customers are concerned about data security and use IPSec VPNs to encrypt data from the wireless router to a router or firewall in the data center.
    In larger networks with tens or hundreds of devices customers demand remote management capabilities and look for SNMP or web based management support on the wireless router. Routers support protocols such as RADIUS so only authorized users can access the device.
    Environmental considerations can be important for oil gas applications. For example, customers may need DIN rail mount packaging, extended operating temperatures or C1/D2 certification.
  • This diagram shows the use case where wireless is a backup WAN connection. In other words, the wireless router has both wireless modem and wired Ethernet connectivity to the WAN or Internet. The router is configured to use the Ethernet connection as primary and automatically fails over to the wireless connection only when needed. This is typical when customers have mission critical networks that demand high availability. Alternatively, it is possible to configure load sharing between the wired and wireless networks.
    Or if you already have a wired WAN router in place you can configure Virtual router redundancy protocol or VRRP so that the wireless router is enabled in the event the wired router is down.
  • Let’s look at access fees. My observation is that if you look at the cost of wireless data plans compared to wireline, generally you find that wireless can be attractive for relatively low volumes of monthly data. The chart on the right shows monthly M2M access fees for several volumes of data from 1 megabyte to 1 gigabyte, from Verizon.com. So for these volumes of data, wireless is competitive with cable and DSL and less than T1 or metro Ethernet. Another feature of M2M plan is the ability to share the data usage among several devices. So that can lower your bill, too.
    In remote locations such as gas pipeline pumping stations it can be a challenge to get wireline connectivity. There just may not be access to DSL, cable or other wireline services quickly. So wireless networks can enable faster time to production, faster return on investment.
  • BBOX has worked with integrators in the building automation space. One example is a boiler upgrade project at a community of a few dozen high rise apartment buildings. The community found that they could reduce the operations and maintenance staffing costs by centrally managing new boilers with Ethernet and IP connectivity. The boiler room of each of the buildings was fitted with a wireless router to backhaul monitoring and control data back to a central operations center.
    Boiler control and monitoring systems are available in IP enabled or serial communications versions. Typically these are configured for low data rates such as 9600 baud and low refresh rates of one sample per 3 minutes. So these systems are a good fit for low cost wireless M2M data plans where you can buy say 5MB of data for less than $17 dollars per month.
  • Security and surveillance is another hot market where cellular wireless is used to backhaul traffic from IP cameras to a remote security operation center. In addition to cellular wireless, these projects often use wireless Ethernet extenders on site for the local area network.
    Construction sites can face a range of security issues, including accidents and the theft of raw materials such as copper wire, copper tubing, lumber, and equipment. CNBC reported that copper theft alone is over $1B annually in the US. Security cameras on your site can help to prevent intruders and potential theft. In addition to boosting security, the presence of a security camera can help settle time consuming disputes with contractors, as well as encouraging productivity during the workday.
    The state of the art in security is IP cameras. An IP network video surveillance system provides a host of benefits and advanced functionalities that cannot be provided by an analog video surveillance system. The advantages include superior image quality, remote accessibility, distributed intelligent video capabilities, easy installation and integration, and better scalability, flexibility and cost-effectiveness.
    IP cameras can have built-in features such as video motion detection, audio detection alarm, active tampering alarm, input/output connections, and alarm and event management functionalities. These features enable the network cameras and video encoders to constantly analyze inputs to detect an event and to automatically respond to an event with actions such as video recording and sending alarm notifications.
  • Let’s look at a few examples of IP camera bandwidth and monthly data usage.
    Video bandwidth and monthly data consumption depend on a number of factors including:
    Number of cameras
    Whether recording will be continuous or event-based
    Number of hours per day the camera will be streaming data
    Frames per second
    Image resolution
    Video compression type: Motion JPEG, MPEG-4, H.264
    This chart gives you the bandwidth and data requirements for 3 examples: 700x480 resolution, 720P and 1080P HD resolution.
    For example the bandwidth of the 700x480 resolution at low quality, 5 frames per second is about 120kbps. Assuming one hour of video is streamed over the wireless network each day, then you will consume about 1.6GB of data monthly.
    The bandwidth of high quality 1080pHD at 15 frames per second is about 6Mbps assuming H.264 compression.
    Here is a tip for minimizing the amount of video that gets passed to the wireless network. You can have cameras record locally like to a NAS or even an SD card at full resolution but use a second stream that's much lower resolution and frame rate for remote streaming. For example, you can have a 3MP cameras recording at 3MP to the local network recorder, but configure the wireless connection to use a low quality VGA resolution substream at 5 fps which is certainly good enough to check on the camera or change a configuration.
  • Mashable.com has a story about how food trucks use tech to drive business. While many food trucks keep it simple and write a chalk menu each day, one food truck has the deep pockets to finance something a bit snazzier. Fast food chain Jack in the Box has a 34'-long Munchie Mobile food truck that boasts a 47-inch digital menu board. Obviously the advantage of a digital menu board one is that the images can change. So what does Jack's digital display show? Typically it lists menu items, pricing and food shots. However, if the Munchie Mobile is at an event or running a promotion then screen can be updated to reflect the offerings.
    There's a lot of potential for digital menu boards, such as Twitter feeds, YouTube footage, truck locations and advertising.
    The digital signage content delivery as well as secure payment card transactions are enabled via the wireless network connectivity. Food truck vendors have found that they can drive more top line revenue with wireless payment card processing capabilities.
  • Black Box’s new WRT4000 series routers have internal 3G/4G wireless modems and 5 Ethernet ports.
    The router has RF connectors for redundant antenna connections to provide spacial diversity – if one antenna is blocked the other antenna may have a better signal. Depending on the physical location of the router it may be necessary to use RF cable to place the antennas near a window for better reception.
    Industrial models feature 2 RS232/485 ports, a rugged metal case and extended operating temps of -40 to 85 degC.
    The WRT4000 series supports static and dynamic routing, switching, and stateful inspection firewall.
    Services include DHCP, NAT and IPSec VPNs with AES 256 encryption.
    Automatic failover is supported among wired and wireless WAN links.
    Remote management via SNMP, SSH, Telnet, and web interfaces are supported.
    The WRT4000 series supports modbus RTU and legacy protocols.
    In the US we support Verizon, ATT, and Sprint networks.
