<div class="gmail_quote">quick email reply i got from the docs in regards to average workload.<br><br># 1 was for a clinic, which wasn't the best of questions to ask.<br><br># 2 was a camera's average workload...so that's a more measurable chunk. i think, but here is a good number for us to start from.<br>
<br>
<div>
here are our answers:<br>
1. It depends on how small we make them<br>
2. Average = 20 patients/day x 5 days week x 4 weeks = 400 pictures/month/clinic that need to be archived.<br>

Subject: Fwd: FW: CIDRZ and GPRS data<div><div></div><div class="Wj3C7c"><br><br>Hi Dr P,<br><br>below is a reply I got from the Celtel guys. Looks promising. <br><br>In building a cost estimate for data infrastructure, I was wondering:<br>
<br>What is the current workload for a single nurse and/or clinic per month? In other words, what is the monthly workload for a camera in a clinic/exam room? We want to do some number crunching to see what the data requirements are for sending every image to the server for archiving. The 100MB per month seems reasonable, David Venn says there is an unlimited plan as well, which is vital for the cidrz server to have to receive all the images coming in from all the clinics.<br>
<br>Thanks,<br><br>Dan<br><br>

<div><span lang="en-us">Hi Mr. Venn,<br><br>We spoke briefly over the phone a few months back in regards to a software development project with CIDRZ involving sending data over GPRS. CC'd to this message is Dr. Parham, the lead point of contact on this effort. The following message asks a flurry of questions in regards to the state of GPRS and MMS in Zambia. We'd like to<font color="#000080"></font></span></div>
<span lang="en-us">get a better sense of what costs to consider when scaling out a nationwide service over CelTel's network.
<div><br><br>The project particulars are as such:<br><br>In a clinic a nurse will take a picture of a patient for diagnosis and evaluation. The image and corresponding data will be sent via GPRS to a central server in CIDRZ's offices. The CIDRZ office server will then MMS the image to a doctor for his/her review.<br>
<br>A few assumptions we will be making in a pilot implementation. <br><br>First, we will assume that the software we develop will streamline the preparation of the data package. <br>Next, we will assume that the nurse is in a place with reasonable coverage such that GPRS (or even better, EDGE) is available to make the transmission.<br>
<br>Of concern though is the actual route that the data will take from the phone out in say, Choma, back to CIDRZ in Lusaka. <br></div><font color="#ff0000">This is local traffic and therefore it will routed locally on a secure pipe.</font></span>
<p align="left"><span lang="en-us">
<div>If the server has an internet connection (and static IP address) assigned by iConnect, how will GPRS data route through the internet, will it it hit out via satellite and back in?<br></div><font color="#ff0000">There are two options to this approach,</font></span>
<br>
</p><p align="left"><span lang="en-us"><font color="#ff0000">1. we plug-in a GPRS router into Server/Lan from GPRS side then you will have the ability to plug more servers or </font></span></p>
<p align="left"><span lang="en-us"><font color="#ff0000"> computers to this router.</font></span></p>
<p align="left"><span lang="en-us"><font color="#ff0000"> 2. Install a GPRS card on your server and then you will not be required to use iConnect internet service for this </font></span></p>
<p align="left"><span lang="en-us"><font color="#ff0000"> purpose.</font></span></p>
<p align="left"><span lang="en-us">
<div>If the server has a GPRS or EDGE card, will it have a static IP or have a DNS entry understandable such that a CelTel GRPS packet will never leave CelTel's internal routers? <br></div><font color="#ff0000">We shall assign you a separate Access Point Name (APN) and dedicate all CIDRZ traffic to this channel and then you shall have fixed IP addresses.</font></span>
<br>
</p><div>
<p align="left"><span lang="en-us">If we go the route of the CIDRZ server having a GPRS/EDGE card for receiving all inbound data from all over the country, what sort of pricing plans are available?<br></span></p></div>
<p align="left"><span lang="en-us">
<div>Celtel access to GPRS network:<br></div>Pay per use - K1,600 per MB<font color="#000080"> </font></span><span lang="en-us"> <font color="#ff0000">- 1579</font></span>
<br>
</p><p align="left"><span lang="en-us">15MB/month - K19,500<font color="#000080"> -</font></span><span lang="en-us"> <font color="#ff0000">Correct</font></span><span lang="en-us"><br>100MB/month - K85,000<font color="#000080"> -</font></span><span lang="en-us"> <font color="#ff0000">Correct</font></span><span lang="en-us"><br>
</span><span lang="en-us"></span></p>
<div>
<p align="left"><span lang="en-us">Below is a pricelist I saw off the web for GPRS coverage, numbers from from July 2007.<br></span></p></div>
<p align="left"><span lang="en-us">Pay per use - K1,600 per MB<font color="#000080"> </font></span><span lang="en-us"> <font color="#ff0000">- 1579</font></span></p>
<p align="left"><span lang="en-us">15MB/month - K19,500<font color="#000080"> -</font></span><span lang="en-us"> <font color="#ff0000">Correct</font></span><span lang="en-us"><br>100MB/month - K85,000<font color="#000080"> -</font></span><span lang="en-us"> <font color="#ff0000">Correct</font></span><span lang="en-us">
<div><br><br>I guess a concern is a centralized aggregation site with a "pay for bandwidth" doesn't make it easy for CIDRZ to scale this service nationwide. Does CelTel have an unlimited monthly data plan for computers? Also, phone plans with unlimited data are of interest too.<br>
</div><font color="#ff0000">Marketing to advise as they are still working on the pricing stracture on this.</font></span>
