Should I buy cheap tablets?

Our users often ask us about the minimal specification for the tablets to be used with Survey Solutions. While we understand the desire to cut costs of conducting surveys, we recommend purchasing the most powerful tablets you can afford. With a very few exceptions, the total survey budget is much larger compared to the budget you spend even on the most powerful tablets. Modern tablets provide much better interviewer experience: they are more responsive and have longer battery life.

Why does the time recorded through date/time question is different from the time reported in GPS question?

An Android tablet has its internal clock. That clock is set based on specifications of the tablet manufacturer and on the user settings. For example, the tablet clock can be synchronized to the network time, or can be set by tablet users manually. The time reported in GPS question comes from the GPS signal provider. We recommend acquiring the GPS signal through satellites disabling the wifi coordinate services. However, geographic coordinates might be acquired through wifi.

My Survey Solutions server is not the latest version. Can I still use it with new surveys?

It is recommended that you upgrade your server to the latest version, but as long as you use only features that were available on your version of the server the new survey should work on the older server. Please note that you will not be able to import to the server questionnaires with features introduced in versions that are later than the version of your server.

Does Survey Solutions require constant internet connection to collect data?

No, Survey Solutions does not require constant internet connection. The data collection on tablet can be conducted offline. The internet connectivity, either 3G/4G or WiFi, is required to synchronize tablet with the server to send completed assignments and to receive new assignments. In some cases, i.e., remote Pacific islands, interviewers go without connection for several weeks. While it is possible not to synchronize for an extended period of time, we recommend to synchronise tablets as often as possible, preferably after each interview, if the connectivity allows.

How can I request localization for the Interviewer and Tester in a new language?

Please contact our developer team and request the localization. We will review your request and, if approved, we will send you Excel files with strings to translate. Once we receive the files with translation from you, we will try integrating the new translation into the next release. However, you should realise that the initial translation is just part of the localisation work. The most time consuming task is to support the localization for the new versions.

Is Internet access required during interviews?

No. Internet access is only required to synchronize data and case assignments, and is not needed during interviews. In some cases the interviewers might go without connection for weeks (for example, remote islands in the Pacific). They synchronize with the server when they reach the location with 3G of WiFi internet coverage.

Is there an offline version of the questionnaire designer?

No. The Questionnaire Designer can only be used online. Survey Solutions evolves very rapidly and we are introducing new features with each monthly release. An online designer allows us to maintain the version compatibility. Another argument in favor of online designer is that in order to use any CAPI software a tablet has to communicate to a server. So, the internet connection is necessary for data collection and thus should also be available for Questionnaire Designer.

Does obtaining a GPS signal require an internet connection?

No, GPS receiver in the tablets relies on satellites to obtain coordinates. So, no internet (3G or WiFi connection) is required. However, you can improve accuracy of GPS signal by pairing the satellite signals with the coordinates obtained from mobile networks.

Can data collected with Survey Solutions be saved/backed up on a USB stick or micro-SD card?

No, we do not support such functionality. This feature will unavoidably lead to data losses and increases in survey management costs. Saving data to UBS generates multiple versions of data that is very difficult to maintain without overriding the useful data. To avoid duplication, Survey Solutions imposes a rule where a particular questionnaire can be only with one agent in the system.
