  • MemHamWAN Expands to Raleigh with New Site on Methodist North Hospital

    On February 13, 2016, HamWAN Memphis Metro along with partner Delta Amateur Radio Club deployed a new cell site at Methodist North Hospital. This site is the third such site to be deployed in the region, and soon much of the Delta Amateur Radio Club’s infrastructure present at the hospital will be brought on network. “We’re excited to have another regional hospital host our equipment,” says Ryan Turner, President of HamWAN Memphis Metro.

  • A Year of East Memphis Coverage

    This day in 2015, HamWAN deployed cell site equipment to their east Memphis cell site. Since then, we’ve added a 720p IP camera, another point-to-point link, network connectivity for a D-Star repeater, and a server has come and gone (due to climate control and power issues, it wasn’t the best site for a server). We continue to offer thanks to Tri-State Repeater Association for taking the equipment and hosting it for us at one of their existing sites.

  • 2016 Expansion Preview

  • Ground Surveys Show Unexpected 5 Ghz Mid-Range Options

    HamWAN Memphis Metro’s second cell site was installed in East Memphis recently, but little investigation on its coverage had been completed before this weekend. Three new ground-level surveys were completed from the North side of the cell site, all supporting greater than 5 Mbps throughput. The surveys have been added to our coverage map, which is located on our website under the Solutions link. At State Rd and Mullins Station Rd (7 km air distance) using a Sextant at 5′ AGL a -76 dB signal was received, which supported 9 Mbps of TCP traffic. At the East Memphis Bass Pro Shops (8 km air distance) using a 31 dB dish at 7′ AGL, a signal which supported 5.7 Mbps of TCP traffic was received. Finally, at US 70 and Ferrell Drive (10 km air distance) using a 31 dB dish at 7′ AGL, a -77 dB signal was received supporting 10.8 Mbps of TCP traffic.

  • Network Provider Ritter Communications Establishes Local Connectivity with MemHamWAN

    Thursday June 4th 2015, HamWAN Memphis Metro installed their first locally-peering edge router with Ritter Communications. Located in Millington, TN, the edge router will provide lower latency access to the internet, while also reducing the hops between HamWAN’s internal network and network carriers.

    For the uninitiated, Dayton Hamvention is the big event annually in amateur radio. It’s a 3 day event in Dayton, Ohio, USA that for the last few years has had over 24,000 people in attendance; that’s about five times as large as most technology shows.

    On this past Sunday, Ryan, Michael, Sam, and Forrest visited Le Bonheur Children’s Hospital to perform a site survey and begin an installation of HamWAN equipment. This location is nearby our existing Southern College of Optometry (SCO) site, but it is slightly higher, requires no tower climbing, and has emergency power.

  • Midtown Memphis Cell Site Live!

    IMG_20141019_175735~2In cooperation with Tri-State Repeater Association, HamWAN Memphis Metro is pleased to announce the deployment of our first cell site, located in midtown Memphis, TN.

  • Hardware Install on First Cell Site Started

    Earlier last week we began the hardware installation on our first cell site! Saturday we’ll continue installation. We hope to have the site operational by the end of the weekend, with KK4IOH Michael as our first initial user. The sector antennas will be at about 150 ft AGL, 435 ft MSL. We’ll have an entire cabinet to ourselves, so eventually we’d like to install a UPS, server, and rack mount switch. Initially, we’ll just have a switch and the radios. We’ll be going back to install an ADSB/transponder/GPS receiver and decoder appliance provided by FlightRadar24.

  • August Progress: First Network Services

    An example graph of network traffic on the WAN port of our edge router; nearly all of this traffic so far is “white noise” from automated attackers and scanners on the internet.

    In August 2014, HamWAN Memphis Metro, Inc began installing the infrastructure necessary to allow for the impending cell site deployments in the greater Memphis, TN region. The following is a brief overview of those activities:

  • First Board Meeting

    Earlier this month, HamWAN Memphis Metro held its first board meeting! This is a short post notifying of this occurrence — read the meeting minutes here.

  • This week’s progress: BGP announcement, edge-router 1, and NTP!

    This week has been a fun week for the team. We received our letter of authorization from Amateur Radio Digital Communications Inc for our 44.34.128.0/21 address space, and thanks to the folks at Threshold Communications and HamWAN PSDR, it is now being announced! This setup gets us right to the edge of HamWAN PSDR, so it’s convenient for working with them. For getting in/out to the rest of the internet, it’s sub-optimal due to the added latency (Seattle isn’t terribly close to Memphis). We still need to find a local partner to announce the space and bandwidth for edge routing.

  • What is “Memphis Metro”?

    Memphis Metro CountiesIt’s in the name, but different people may have different ideas of what it means. Officially, it’s a Metropolitan Statistical Area defined by the United States Office of Management and Budget known fully as “Memphis, TN-MS-AR Metropolitan Statistical Area”. It is made up of the following counties:

  • User Coverage Map: How is it Made?

    Today I document how I generate my coverage maps, and I want to take my maps a step farther to calculate which amateurs fall in the coverage area. I’ll describe the complete process using a potential cell site “Crosstown”.

  • Status report: sites, organization, and edge

    Our first cell site is about half way purchased, and we’re currently meeting with potential site owners to discuss arrangements. Our site planning checklist is available here. We have a few potential options in the Midtown region, for which our coverage would look similar to this:

  • Presentation at Memphis D-STAR, February 2014

    On February 8 2014, Ryan K0RET presented to Memphis D-STAR about HamWAN Memphis Metro. We originally anticipated having a video of this presentation, but the quality was poor due to no lighting. As a result, instead we’ve attached a PDF of the slides that he presented. After the slides, Ryan demonstrated a miniature network, made up of a partial cell site and two nodes. With this, he demonstrated pinging between the two nodes, RouterOS’s built in bandwidth test between a node and the core router, a 50 MB file transfer via FTP, MJPG streaming of a 1080p webcam, and raw IQ streaming of an SDR. After this, there was a 25 minute Q&A session, in which Bart and Nigel of HamWAN PSDR participated via Google Hangouts. Questions ranged from how the network could potentially be used in amateur contesting to how does NV2 cope with multipath fading.
