> Hi Mr. Venn,
>
> 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
>  get a better sense of what costs to consider when scaling out a
> nationwide service over CelTel's network.
>
> The project particulars are as such:
>
> 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.
>
> A few assumptions we will be making in a pilot implementation.
>
> First, we will assume that the software we develop will streamline the
> preparation of the data package.
> 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.
>
> Of concern though is the actual route that the data will take from the
> phone out in say, Choma, back to CIDRZ in Lusaka.
> This is local traffic and therefore it will routed locally on a secure
> pipe.
>
> 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?
> There are two options to this approach,
>
> 1. we plug-in a GPRS router into Server/Lan from GPRS side then you will
> have the ability to plug more servers or
>
>     computers to this router.
>
>  2. Install a GPRS card on your server and then you will not be required
> to use iConnect internet service for this
>
>      purpose.
>
> 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?
> 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.
>
> 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?
>
> Celtel access to GPRS network:
> Pay per use - K1,600 per MB  -  1579
>
> 15MB/month - K19,500          - Correct
> 100MB/month - K85,000        - Correct
>
> Below is a pricelist I saw off the web for GPRS coverage, numbers from
> from July 2007.

> Pay per use - K1,600 per MB  -  1579
>
> 15MB/month - K19,500          - Correct
> 100MB/month - K85,000        - Correct

> 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.
> Marketing to advise as they are still working on the pricing stracture on
> this.

> I would love the chance to speak with you again.  I'm currently in the

> really appreciate it.
