Tshwane is South Africa’s top wifi spot

first_img8 September 2015Tshwane’s public wifi build programme is the largest of its kind in South Africa, new research by the firm BMI-T has confirmed.BMI-T undertakes business-to-business commercial and industrial research. It tracks public and private sector wifi hotspots. In its study, BMI-T found that South African government deployments had been on an expansion trend over the last year to 18 months.The city Tshwane’s free wifi build programme was the biggest in terms of users, footprint and access points, the data showed.Christopher Geerdts, the associate telecommunications consultant at BMI-T told, said provincial government deployments in Western Cape were the next biggest after Tshwane.“In terms of government sponsored deployments there are currently around 1 800 active hotspots in South Africa, with the bulk of these being concentrated in Project Isizwe’s Tshwane deployment, and projects in the Western Cape,” Geerdts said.However, BMI-T warned that free wifi risked being unsustainable.“Someone ultimately has to pay for these services,” Geerdts argued. “Public projects can be all or part sponsored by national, provincial or local government and/or the private sector. Project Isizwe received donated bandwidth from Neotel. Other ISPs and telcos (telecommunications companies) could also contribute, especially if there is some CSI (corporate social investment) capital to be gained from this.”In Tshwane, Project Isizwe registered 720 000 unique wifi users, who are given a 250MB cap per day. The non-governmental organisation said that only 7% of users reached their cap. In Western Cape, public wifi is provided in Mitchell’s Plain and Khayelitsha, where users have a 3GB cap.However, Geerdts envisioned a model where wifi internet access was affordable rather than free in the longer term.“Overall we think that the country may be looking for an affordable model more than a free model. Customers are investing in smartphones and there is evidence they will pay for data if the pricing is improved and (for wifi) coverage and payment methods improve,” he said.Source: News24Wirelast_img read more

Business ByDesign: SAP Delivers a Quality SaaS Service

first_imgCognitive Automation is the Immediate Future of… Massive Non-Desk Workforce is an Opportunity fo… alex williams Related Posts 3 Areas of Your Business that Need Tech Nowcenter_img SAP’s Business ByDesign (BYD) will be released at the end of July, marking the company’s next steps into the world of subscription services for enterprise customers.It certainly is a small step into the SaaS world for SAP. And it has been a long time in coming for the company.But it’s a start even though you hear many analysts scoff at the suggestion that SAP is showing any cohesive approach around cloud computing and its product offerings.It’s symbolic of a general sentiment we encountered at SAP Sapphire Now. You sense that the company needs to find its bearings and develop a cohesiveness around its product strategy.Though we know that BYD has its skeptics, we found the presentation of the user interface to be on par with major SaaS services. It also has the underlying infrastructure to make it a viable service for companies to extend the service in the manner they wish. SAP’s Peter Lorenz showed us the service at Sapphire Now and how it performs on the iPad.BYD is elegant on the iPad. It’s a corporate directive to instill beauty into sophisticated, real-time SAP products. BYD uses Silverlight fro its front end display. It is decoupled from the back end system. It means that BYD can have one model rendered to different platforms. It’s pretty cool. API’s and OpenSocialBYD connects to Google’s OpenSocial. It uses API’s that makes BYD a framework that customers can build upon.In that sense, the BYD platform provide the capability to collaborate and perform transactional functions. Data for a customer can be mixed and edited between parties and then generated into a proposal. That kind of combined capability could be powerful for small and medium sized businesses. Most smaller companies would prefer not to have an IT department. With BYD they can do the work to keep the company running without the concern about maintaining the technology on its own hardware.That’s a compelling opportunity for the small and medium sized business. A service like BYD gives these smaller companies real-time capabilities, mobility and the option of paying on a subscription basis, starting at $149 per month, per user.That’s the promise of BYD. Now the only question is how fast the service will be adopted and how this model is realized across the wide breadth of SAP technologies.[Disclosure: SAP paid for a plane ticket and hotel room for Alex Williams to attend the the SAP Sapphire Now conference in Orlando.] Tags:#enterprise#news#Products#saas IT + Project Management: A Love Affairlast_img read more

How to Ensure a Low Pressure Drop Across a High-MERV Filter

first_imgAllison Bailes of Decatur, Georgia, is a speaker, writer, building science consultant, and the author of the Energy Vanguard Blog. You can follow him on Twitter at @EnergyVanguard. A shoutout to our sponsorsAs mentioned at the top of this article, we got a new Mitsubishi ducted minisplit (and two ductless units) installed in our office.  Mitsubishi donated the equipment for this project, and PV Heating and Air, a home performance contractor in Atlanta, donated their labor.  Ultra-Aire donated a ventilating dehumidifier for our office and now that we head into warmer, more humid weather, I’m excited to see the difference it makes in our indoor air quality and comfort.  Finally, Aprilaire donated the filter cabinet and MERV-13 and MERV-11 filters.  We like these companies and recommend their products and services. Last August I began a series of articles on filtration and indoor air quality.  You can find them listed in the related articles section but let’s do a quick review here:  We spend a lot of our time in buildings.  A lot of indoor pollutants are generated in the kitchen and not removed by the range hood.  The consensus among indoor air quality researchers is the particulate matter that’s 2.5 microns or smaller (PM2.5) is one of the worst for health.  And finally, good filters (i.e., MERV-13) can remove a lot of the PM2.5 and other pollutants but experience as well as studies show they often don’t, for a variety of reasons.So how do we fix this situation?  How can we get a high-MERV filter and have it do a good job of filtration without causing problems with the air flow in the heating and cooling system?  The answer is simple:  Make the filter big enough.  John Semmelhack, owner of building science firm Think Little in Virginia, spoke about this topic last year at the North American Passive House Conference in Boston.  Also last year, we got a new Mitsubishi ducted minisplit system here in the Energy Vanguard office in Georgia (meticulously installed by PV Heating and Air).  Let me show you what’s possible.High-MERV filters with low pressure dropSemmelhack spoke about ducted minisplit heat pumps in Boston and towards the end of his talk he got to the topic of filtration.  (Download the presentation and see the filter section starting with Slide 25.)  He used a 2-inch deep MERV-13 filter in a filter grille.  The ducted minisplit they used was a one-ton system moving 400 cubic feet per minute (cfm) of air.  The pressure drop across the MERV-13 filter was 0.0274 inch of water column.  Yes, really!What was their secret?  They used a 20″ x 20″ filter.  That’s all.  Just make the filter bigger and you get a lower pressure drop.  The key is to look at the ratio of the filter area to the air flow rate.  In their case, the filter area was 2.78 square feet (sf) so the ratio comes out to be 2.78 sf ÷ 400 cfm = 0.007 sf/cfm.  Using the nominal air flow rate of 400 cfm/ton of capacity, we can make the number look a little friendlier:  2.78 sf ÷ 1 ton = 2.78 sf/ton.Hang onto that calculation.  I’ll come back to it in a minute.John Semmelhack’s 2-inch filter grille with MERV-13 filter.  [Photo credit: John Semmelhack]In our office, we got a similar result, although our pressure drop is a bit higher.  We have an Aprilaire filter that’s also 20″ x 20″ but it’s a 4-inch-deep filter in a cabinet near the ducted minisplit air handler.  Our pressure drop is 0.0604 i.w.c., as you can see in the photo below.  That’s higher than Semmelhack achieved with his system but still really low compared to what you might expect.The Air Conditioning Contractors of America (ACCA) Manual J load calculation protocol says to allow 0.10 i.w.c for a filter… and that’s generally for a standard 1-inch-deep MERV-2 filter, not a 2-inch or 4-inch MERV-13.  Ask contractors what the pressure drop across a MERV-13 filter is and they’ll probably tell you something like 0.25 i.w.c.The pressure drop across our MERV-13 filter is a very low 0.06 inch of water column.  [Photo credit:  Energy Vanguard]When we measured the air flow in our system, we got 363 cfm, so our ratio of filter area to air flow is 0.008 sf/cfm, or 3.1 sf/ton when converted using 400 cfm/ton of capacity.  We have more filter area per unit of air flow, but we got a higher pressure drop than Semmelhack.  Some of you building science geeks are wondering about that, I’m sure, and so am I.The main difference between the two systems is that our filter cabinet is installed in the middle of the return duct, whereas Semmelhack used a filter grille.  We installed a filter grille, too, and currently it doesn’t have a filter in it.  We’ll be testing that at some point, though.  Another difference between Semmelhack’s pressure drop and ours is that he used a 2-inch-deep filter and ours is 4 inches deep.  We’ll keep measuring our pressure drop, and I hope that with more data, our average pressure drop will be lower.But we’re still happy with 0.06 i.w.c.  The key to whether it’s a good number or not is how well it fits in with the total pressure drop in the system compared to what’s allowed (the total external static pressure, or TESP).  More on that in a future article.A simple rule of thumb for low pressure drop across a high-MERV filterI’ve shown you data from two MERV-13 filters now.  Both are much lower than you’d measure across many of the MERV-13 filters installed in the wild, and I’ve given you the key to achieving similarly low pressure drops.  It’s simply to increase the filter area relative the air flow rate.The two systems described above had ratios of 2.8 sf/ton and 3.1 sf/ton.  You don’t have to go that high, though.  David Butler, an HVAC designer and frequent commenter here, said he uses 2 sf/ton as his guide.Home performance contractor extraordinaire Mike MacFarland of Energy Docs in Redding, California does it a bit differently. He uses 250 feet per minute (fpm) as his absolute maximum face velocity for air moving across the filter but generally sticks to 200 fpm or lower. The conversion from face velocity (ft/min) to filter area per ton of capacity (sf/ton) is straightforward using the equation q = A x v. (You may recognize the product of area and velocity from the continuity equation for air flow.) The answer in this case is that 200 fpm = 2.0 sf/ton in this case, the same number David Butler uses. MacFarland designs for conventional heat pumps rated for 0.5 i.w.c. total external static pressure (TESP) and had never had a system come in at a TESP higher than 0.35 i.w.c., with most of them measuring 0.30 i.w.c. or less.With smaller capacity minisplit heat pumps, getting filter sizes to 2.5 or 3.0 sf/ton isn’t that hard. With conventional systems, it’s not so easy. With a 2.5 ton system at 3.0 sf/ton, for example, you’d need 7.5 square feet of filter area, or a 30″x36″ filter, but you’d have a hard time finding one that size so you’d have to install two 18″x30″ filters. You can do it if you really want to, but if you use MacFarland’s rule of 2.0 sf/ton, the resulting 24″x30″ filter (or equivalent) is much easier to find space for and you can still get a low pressure drop.So here’s your rule of thumb for filter sizing:Filter Area = 2.0 square feet for each 400 cfm of air flowDo that (and size your ducts properly) and you shouldn’t have to worry about high pressure drops across your filters… at least not when the filters are relatively clean.last_img read more

Port of Oakland Terminals Night Gates Here to Stay

first_imgzoom Port of Oakland said that its busiest marine terminal Oakland International Container Terminal will make evening operations permanent following a three-month trial.The port said that night gates will continue to take pressure off busier daytime container pick-up or delivery operations.Oakland International Container Terminal launched night gates in late June when it started offering full night operations from Monday through Thursday for truck drivers to haul cargo.According to data compiled by the terminal and the port, about 1,300 container transactions nightly have migrated from day to evening. The night operations also led to a drop in average transaction time for truck drivers from 96 minutes in August to 79 minutes last week, while thirty percent of trucking companies at the port reduced congestion surcharges assessed to customers for picking up containers.A survey conducted by the port showed that 74 percent of cargo owners use Oakland night gates due to less terminal crowding. Sixty-five percent of owners said that night gates contributed to an improvement in transaction times.Oakland International Container Terminal said it will continue to charge customers a USD 30 fee to finance night gates. About 6,000 trucks pass through the terminal’s gates daily, making it one of the busiest in the US. It handles 70 percent of the containerized cargo in Oakland.A neighboring Oakland marine terminal, TraPac, said it is currently experimenting with night gates.last_img read more
