[Cidrz] Fwd: CIDRZ and GPRS data

Fri Apr 4 11:10:52 EDT 2008

quick email reply i got from the docs in regards to average workload.

# 1 was for a clinic, which wasn't the best of questions to ask.

# 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.

 here are our answers:
1. It depends on how small we make them
2. Average = 20 patients/day x 5 days week x 4 weeks = 400
pictures/month/clinic that need to be archived.

Hi Dr P,

below is a reply I got from the Celtel guys.  Looks promising.

In building a cost estimate for data infrastructure, I was wondering:

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.

Thanks,

Dan

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
states in Boston, if there's a time convenient for you to chat on this, I'd
really appreciate it.

Many thanks,

Dan
