Is RFDP8 better than BlueTooth, ZigBee, WLAN and other protocols?
Posted on | September 2, 2010 | No Comments
RF Digitals RFDP8 proprietary patent-pending frequency agility protocol operates in the internationally accepted 2.4 GHz band. The RFDP8s leading-edge advanced algorithm is not burdened by a heavy-weight stack as is BlueTooth, ZigBee, WLAN and other protocols, which are well suited for cross-manufacturer interoperability. The RFDP8 protocol is highly robust and effective where there is a need to penetrate through a high saturation of RF noise which is common in nearly all environments today.
It is especially effective and can easily coexist in heavy WiFi environments, which very few technologies can do successfully without the need of excessive processing power. The protocol strategically changes channels frequently to deliver its payload to the destination device reliably, yet not too excessively as to demand too much internal processing power which allows it to run with a very low current consumption profile and fast start up times allowing substantial flexibility with implementation. The RFDP8 protocol reduces the amount of on-air traffic and unnecessary chatter due to its unique and highly efficient design, which does not require bilateral registration and association as do many other technologies today. The RFDP8 does not require ack-nacks to complete a packet delivery, it’s unique technique of packet delivery, recovery and correction allows it to work as a one-way link, hence drastically simplifying users’ applications which always results in more a robust wireless system. The RFDP8 protocol combined with RF Digital’s leading-edge RF Module hardware delivers a highly robust method of delivering user data from point to point, point to multi-point or multi-point to multi-point, transmitter-receiver, transceiver, serial or switch on/off data modes. The protocol is designed to work seamlessly with RF Digital’s hardware modules, the combination results in ultra long range at ultra low currents without concern for compliance approvals since modules such as the RFD21733 come with FCC approval for USA and have passed CE – ETSI emission testing for European requirements. The RFDP8 protocol adds several dB of range gain passively through it’s advanced data recovery technique which pulls valid data out of a noisy environment adding effective gain which results in more range, delivering the net result, which is a very robust wireless system. All of this is built into the overhead of the RFDP8 protocol and RF Digital modules, so it’s all done behind the scenes, allowing the user to focus on building their application and simply putting data into the radio device as a wireless pipe and easily receiving it on the other end.

CSD call / replacement of an analogue modem
Posted on | September 2, 2010 | No Comments
CSD call / replacement of an analogue modem
For the data call on GSM, UMTS or 3G also called CSD (circuit switched data) and replacement of an analogue modem to a wireless cellular modem please note the hints as below:
- Activate auto answer and fixed baud rate may be. Store your profile with AT&W.
- Use SIM card preferably offered by T-Mobile Germany. Deactivate the PIN query. Please note that Vodaphone Germany does not allow the deactivating of the PIN query as standard. For other countries we can help with recommendations on request by email.
- Standard SIM cards (Pay as you go, prepaid and SIM cards with subscription) support outgoing data calls only. Please make sure to have this service activated on your SIM card by the GSM operator for the first tests. For incoming data calls you will need a special subscription. Pay as you go/ prepaid SIM cards often do not support incoming data calls.
- In the final application we recommend a SIM card that support “Data Only”. Data Only SIM cards of T-Mobile supports incoming and outgoing data calls and GPRS and SMS as well. We also can help with special tariff contracts and European data flat rates.
- Force bearer type with AT+CSNS=4 to data permanently so that by multi numbering and call from an analogue modem a data connection can be set up. Please note that worst case the GSM base station sends no bearer code. The default bearer in most GSM modems is voice. If no bearer code will be forwarded, the modem will connect a voice call and this will then end in a “No carrier” message at the calling modem.
- Please take care that the GSM operator that you will use supports CSD data calls. In USA, Canada and by a few operators in South America CSD is not supported. They offer packet switched data on GPRS (GPRS) only!
- Take care that some GSM networks are supporting V.32 and other the V.110 protocol better. The protocols can be changed by using of AT+CBST. If the changing of the parameters of the selected protocol can optimise the communication. If you are able to change the settings of used protocol by SMS, then you will be able to optiimise the protocol and parameters remotely by SMS.
For further question on CSD, modem call, analogue modem to GSM connection, ISDN, V.32, multi numbering, single numbering just give us a call or better an email. Normally we heard about all issues around GSM to GSM, GSM to PSTN analogue, GSM to ISDN, ISDN to GSM, PSTN analogue to GSM data communication by our last 15 years in consulting and support in GSM and GPS communication before. We will be glad to support you too.
