THOUGHT: W-LAN vs. GPRS - which one is my personal favorite while traveling?

My job requires lots of traveling, and with W-LAN being omnipresent in the news I also expected to find W-LAN hotspots reflecting the media presence: easily accessible and everywhere available at low cost. Equipped with notebook and W-LAN-PCMCIA card, and more recently with a Pocket PC (XDA II) with W-LAN-SD card, I was ambitious to find high-speed wireless Internet access wherever I went. I further was interested in the question if W-LAN is already becoming a serious threat to GPRS, the current prevailing wireless Internet access technology in Europe. However, after a couple of months, my readiness to use W-LAN while traveling significantly declined.

First reason: the prizing
The major reason for me to put W-LAN behind GPRS while traveling is the current prizing schema. Just in case I found a hotspot: try to find out about the prizing! It is one of the well hidden secrets on the portal sites. I always got the impression the operators are ashamed of their prizes. On average, half an hour of wireless Internet access costs about 5 Euro. In my naivety, I initially thought I could use up the offered time units minute by minute, log in and out when I need it. But in all cases I have seen so far, when buying, e.g., 30 minutes of W-LAN time, once the unit is activated, the time runs out; a rather costly option for short email checks. But don't expect this fact to be pointed out on the websites. It's usually a footnote... if at all.

With GPRS, the five Euro per half an hour W-LAN time means about 3-4 MB of GPRS data traffic in my home country: enough to check the emails for a few days; without attachments of course! Even when roaming, I still get roughly 0,5-1 MB for five Euro and do not need to struggle with any access "barriers" such as prepaid cards or access codes etc. For instance, this article was sent from Prague via GPRS, had 7 KB and did cost about 0,20 Euro to send! 

Second reason: the access management
Even worse is the situation when traveling outside from my home country. Being at home, I easily can get a login password via SMS from my local operator who then charges me via my phone bill. Outside of Germany, I usually need to purchase a prepaid card with time units. But even buying is often extremely difficult. Staff at the selling points rarely knows what I am talking about, not to mention that no technical help is provided anyway. But much worse... the short time unit cards are usually gone: honestly, who wants to buy 24 hours of access time for a 5-minute email check, even if there are some more checks throughout the day? That's a very expensive email check!

I have to admit that there is some improvement in the access management with providers going to offer Europe-wide accounts, but it's still the pricing that matters, as I have to pay for myself. It appears to me that the wireless freedom is only targeting wealthy business traveler! But how many managers are transferring last minute PowerPoint files or are constantly sending bulky email attachments? Can those people really create the expected return of investment?

Third reason: the availability
Availability is another annoying point: when I urgently need wireless Internet access while on the go, I am sure I won't find an access point at all. Of course, there are lots of hot-spot finder in the Internet, but that's exactly the point: how to find the hot spot without Internet access? The often mentioned free access points in the public are rarer than expected; and using a unprotected private access point was never an option for me. Hence, only occasionally I was able to get connected for free sitting in a cafe.

Fourth reason: the battery drain
In case you know when and where you can recharge your device, the power drain through W-LAN usage is not a problem. But when traveling, not knowing how many hours are still ahead before reaching the next socket with time for a recharge, the power drain is still an issue. If you don't watch your battery status, the wireless mobility is very rapidly turning into a powerless mobility. I was very unpleasantly surprised when I noticed how much power W-LAN requires compared to GPRS.

Final conclusion

Maybe, I just had bad luck during the last months, or I am too stupid to find the right spots. But after my first enthusiasm was gone, I decided not to rely on W-LAN anymore as a first option, and not to struggle with all the access troubles as described above. If W-LAN is available and the prizing is right, OK, I give it a try and enjoy the speed, but generally GPRS is my first choice for sending and receiving emails. Wherever I go in Europe in these days, there is GPRS coverage, easily accessible, reliable and with transparent prizing.

When traveling, my requirement is connectivity when I want and not when the access point allows it. That's wireless freedom as I understand it. In my case connectivity comes first, than bandwidth. This of course, is my very personal and subjective conclusion from my recent travels in Europe. The situation may change in the near future and render this observation obsolete, but despite the media presence, my experience is that the W-LAN coverage is still in its very early beginnings. As long as W-LAN operators are not reaching a general roaming agreement with easy access and fair prizing, I cannot see W-LAN in becoming the traveler's first choice.

But back to my initial question: is W-LAN threatening the GPRS-UMTS business? In the current stage I would say not at all. There is one major point that became neglected in all the discussions: wireless access does not automatically mean mobility. But things may change anytime soon. I'll keep watching.

Cheers ~ Wolfgang

Wolfgang, thanks for your thoughts and mostly I have to agree with you!

While I enjoy using W-LAN in Hotel lobbies, bars, convention centers or offices - searching for it is a pain and not useful at all. As you said - you are wasting more time to find a HotSpot, getting a voucher and getting the account activated than just using GPRS.

While it was fun some time before to find a public HotSpot now it becomes more annoying to find one than useful at all.

A personal experience from me: When I flow to my girlfriend on new years eve I had some time I spent in the Lufthansa lounge which is equipped with Wi-Fi, provided by Vodafone, and I had to send some larger E-Mails and had to work on my server, so buying 30 minutes was just fine for me - even if it is also expensive but the speed I got - for Remote Terminal Client was worth to pay for it.

However, when I flow back on 2nd January, again I had to spend some time in the Lufthansa lounge and I just checked my E-Mails and some sites which I did with GPRS for 2 reasons:

1. I had more time to stay there than 30 minutes only and the 1 hour voucher was/is definitely too expensive.

2. I haven't used the access for 60 minutes but half of the time I read my E-Mails and the sites I've visited.

So yes, it's too expensive at all and mostly useless if you don't stay in this area for a common time to buy a day voucher.

In the US, the availability of hotspots is really not a problem, they are pretty available.  You are absolutely right about the battery drain, but the speed differential (and my patience differential) makes me prefer the WiFi alternative if available.

In the Philippines, the pricing is the other way around.

WiFi can cost about USD 6.25 (Pesos 350) for 10 hours a month.

On the other hand, USD 6.25 is only equivalent to a 1.4MB download thru GPRS!!!

Jayson,

You said, 10 hours a month. How do you consume the 10 hours? Are there any time units, how do you authorize yourself? Is WiFi provided by your GSM-GPRS operator? How about the coverage? Sorry about all the questions, but it seems to be an interesting model.

Many thanks in advance ~ W

Hm, Wolfgang, while I agree with almost all you write I still come to a different conclusion. For me it's pretty a question if my house should have a shower or a bathtub - simple answer: both!

I wouldn't wanna miss WiFi while I'm at the Office or at home - and I'd rather use it there since it;s simple and reliable. But I also wouldn't wanna move away from Bluetooth to ActiveSync or for my headset.

So I think the questions is not so much "this" or "that" but to fond what works out best for you and our environment.

Cheers

Frank

Frank,

You are absolutely right. All access technologies should be used if there is a benefit for us.

My observation describes the situation as it is Europe, when you are traveling and you need to check your emails. That's where I find GPRS more convenient, easier to access and cheaper than W-LAN.   

I never wanted to trigger the impression that Wifi is not to be used.

Wifi is great, and I am using it thoroughly at home and at my workplace. It's just the current prizing and access management of public hot-spots that needs some "improvement".

Cheers ~ W

@wolfgang

WiFi services in the Philippines are not operated by the GSM-GPRS networks (although some might be affiliated).  They are operated by Internet Service Providers (ISPs).  This means that their business model is similar.  WiFi service is priced in the same manner as an ISP (they charge per time you log on).  Of course you will be provided a password to keep track.  But since coverage is limited and different hotspots have different providers sponsoring it, sticking to one provider and paying a monthly fee may not be feasible.  Prepaid accounts are also available, which allows you to switch providers depending on the hotspot you are in.  Prepaid accounts have different schemes (some may be limited to 1 session, others carry over, others may expire after a week or a month, etc.).

Jayson,

Many thanks for your interesting description!

By the way, I am just sitting in Prague. Wifi is provided by a local GSM operator. Since not being a regular customer, I would need to purchase prepaid cards which are valid for 10 hours, non-stop. The prize: comparable to an excellent meal in the evening, just to keep the relation. Hence again, I am sticking to GPRS for checking my private emails.

During the day, I have occasional access to "wireline-based" Internet anyway.

Cheers ~ W
