Pacific Rim - OST (2013) [320 Kbps]

The Secretariat of the Pacific Community (SPC) has made strenuous efforts to address communication imperatives for its programme delivery to its member countries. Initially, it used the Internet to assist in programme delivery. However, the low availability and high costs of telecommunications in Noumea and Suva hampered these efforts. The use of PACNET (the communications service of the Pacific Public Health Surveillance Network) was very successful but restricted by communication capabilities and lack of connectivity. In 1998 the capacity was limited to 28.8 kilobytes per second (kbps) in Noumea and 1.9 kbps in Suva with no possibility of obtaining additional capacity at affordable costs through the commercial telecommunications carriers. The ComET project has now installed 7.2 metre antenna and associated equipment at each of the Secretariat's offices in Noumea and Suva. This allows 24 hour per day access to the PAS2 satellite for high speed transmission of voice, data and video traffic. Connection to the Offratel premises in Nouville via the Celeris high speed backbone operated by OPT has linked this to the internet and thereby to member countries and territories, and the rest of the world. The ComET project began transmission in March 2000 and has addressed communication problems, and thereby improved the SPC's programme delivery (examples given in this paper) to it's members at affordable costs within the Secretariats existing budget.

Pacific CSI said it is offering wireless Internet services ranging from 128 kilobits per second (kbps) to 10 Megabits per second (Mbps) to more than 100 corporate customers in Korea. U.S.-based Solectek manufactures high-speed wireless equipment.
9.2 The US Digital Cellular TDMA system uses a 48.6 kbps data rate to support three users per frame. Each user occupies two of the six time slots per frame. What is the raw data rate provided for each user?
The GSM TDMA system uses a 270.833 kbps data rate to support 8 users per frame.
A. What is the raw data rate provided for each user?
B. If guard time, ramp-up time, and synchronization bits occupy 10.1 kbps, determine the traffic efficiency for each user.
The Pacific Digital Cellular (PDC) TDMA system uses a 42.0 kbps data rate to support 3 users per frame. Each user occupies 2 of the 6 time slots per frame. (a) What is the raw data rate provided for each user? (b) If the frame efficiency is 80% and the frame duration is 6.667 ms, determine the number of information bits sent to each user per frame. (c) If half-rate speech coding is used, 6 users per frame are accommodated. Determine the number of information bits provided for each user per frame. (d) What is the information data rate per user in half-rate PDC?
The Personal Digital Cellular (PDC) Time Division Multiple Access (TDMA) system uses a 42 kbps data rate to support 3 users per frame. Each user occupies 2 of the 6 time slots per frame. The frame efficiency is 80% and the frame duration is 6.667 ms. Determine:
(i) the raw data rate provided for each user,
(ii) the number of information bits sent to each user per frame, assuming no overhead in each slot.
(iii) the number of information bits provided for each user per frame, if the speech coding, which reduces the data rate by half, is used and 6 users per frame can be accommodated, and
(iv) the information rate per user in this half-rate compressed PDC system
The Pacific Digital Cellular (PDC) TDMA system uses a 42 kbps data rate to support 6 users per frame. If the frame efficiency is 80% and the frame duration is 6.667 ms, determine the number of information bits sent to each user per frame.
Question No 3
A TDMA cellular system uses 42 kbps data rate to support 4 users per frame. Each user is uniformly allocated 2 out of 8 slots per frame.
What is the raw data rate provided for each user?

If the frame efficiency is 80% and the frame duration is 6.667 ms, determine the number of information (payload) bits sent to each user per frame. [5]
I am currently using MINI M4 STM32, with an STM32F4RG15 MCU.I am facing issues wherein I can't increase the CAN baud rate beyond 250 kbps. Whenever I try to change the parameters to set the baud rate to 500 kbps or even 1 Mbps, CAN stops working and no messages are sent on the bus from the STM32.
Additionally, please note that for STM32F4, the BS1 = TS1 + 1, BS2 = TS2 + 1. From your config for 250Kbps, if the clock source is 16MHz so you lost 2 tq for calculating the bit timing. So the actual clock is 222kbps (correct me if the clock is not 16MHz). For slow speed, may be it is accepted by the device so you could transmit/receive message.
