1. From technical point of view, it makes perfect sense to put a pico/femto base station in indoors. Indoors is meant to be covered by indoor BS.

2. Only selected (by MAC address) terminal can log on to the BS makes perfect sense too. Imagine competitor loading up the BS with rogue terminals. And to feed you with the truth, competitor go great lengths to sabotage each other.

3. I guess you've misinterpreted what's best effort. If your modem receives strong & good signal and the base station is not loaded. Definitely you'll get your "satisfactory" speed. They are not lying to you, the terminal that you have is able to perform that kind of speed.

I'm not affiliated with P1, I'm just sharing to you the technical side of your experience.

a) 10Mbps could stand for your AAA subscriber profile. AAA is the server that controls how much you can get if everything else is ideal. An example would be 2Mbps by streamyx is controlled by similar server even though it can go more than 20Mbps.

b) Let me explain to you how can you get your perfect speed.
1. You must have a terminal that is capable of going up to 10Mbps as the network is fixed but this is the variable. Checked as tech specs say 30Mbps (with MIMO).
2. You have to have strong signal (RSSI) so that the air interface can use higher modulation such as 64QAM. This can be done by being near to the tower. My personal experience tells me you have to be within 200m with the tower and there's line-of-sight (LOS).
3. You must also have low interference (CINR). This cannot be controlled solely by you. Interference comes from all angles, it would take me too long to explain all of them and how to solve them.
4. The base station that is serving you is not loaded. Typical WiMAX base station can support 45Mbps (even Clearwire, US is giving this figure). This 45Mbps should not be confused with "are you saying that only if 4 person is using the base station then only I can get 10Mbps?". There are calculations to determine how many actual subs can enjoy 10Mbps depending on over-subscription/over-booking/contention ratio. Complex calculation aside, I would say about with 100 subscriber (active+idle) using it the same time, 10Mbps is achievable.
5. The backhaul needs to have sufficient capacity. P1 have to make sure that they have sufficient backhaul to satisfy the data hungry WiMAX access.
6. 10Mbps from where is a big issue. There can be more than 15 hops before you reach your source. Any hops that cannot satisfy your 10Mbps requirement will be a bottleneck. This is not P1's fault.

If your environment can satisfy 1 to 6, then you can enjoy your 10Mbps.

c) "Nature" which you deem is a lame excuse actually plays a big role in wireless network. Many people thinks that modern technology can defy laws of physics. Terrain (hill/valley/etc), foliage (trees/bushes/etc), weather (rain/thunderstorm/etc) and topology (dense urban/rural/etc) greatly affects network planning. An example that is closer to your heart, just take wireless signals as how far can you see.
1. If there's a hill in front of you, you can't see over the hill right?
2. If its raining, can you still see something that is 1km away?
3. If there's a big bush in front of you, can you see over it?
4. If there's a big building in front of you, can you see over it?

ask P1 to install this at your home and 10Mbps is a sure thing.

That's an outdoor base station RRU unit, not suitable to install it indoors.

yes i was in PC Fair KLCC today. Speed in the P1Wimax booth was impressive - 7Mb/s! Later when i went to Acer booth next hall with P1wimax wiggy modem - dropped to 1.5Mb/s only! Con job?? sad.gif

Refer to point B above, many factors affect the DL speed.

No eye sight doesn't work like radio wave. I was giving an example in layman terms. May be I should use sound instead.

I was talking about the hops should be able to handle the requirement smile.gif Backhaul was also mentioned in point 5.

I've seen the RRU for ALU and that's the shape of it but it's 1 year ago, may be they have new models now. Using microBS to cover indoors is not suitable but it's workable. You'll then need attenuator and indoor antenna.

S1: Like what I've mentioned before, throughput calculation is not as simple as total throughput divided by user throughput to get the number of user. The above calculation is flawed because you are assuming dedicated throughput where as P1 is not selling a dedicated throughput.

Over-subscription/over-booking/contention ratio (btw, all means the same thing, just that different branch of network uses different names) should be considered. I do agree that the sales personnel is misinformed, unless he's trying to say 10Mbps/sector which is possible but a bit low when compared to other deployments worldwide. Typical WiMAX BS will have 3 or 4 (not so common) sectors.

All of us wishes to have a non "best effort" connection but that means subscribing to a dedicated line with will cost much more. Many don't realize that it's difficult to add additional capacity to a current network, not to mention costly. Michael Lai has complaint to the media before about the cost and the red tape to built towers is hindering the network rollout.

bottom line: is is reliable on the speed that you got?

Off topic: Here's a radar chart comparing Cellular vs WLAN vs WIMAX (http://www.dailywireless.org/2005/08/25/wimax-vrs-wifi/)

This article is too old and bugged with errors. The chart is not accurate too, WiMAX will have better control on QoS compared to Cellular network.

You are missing the point here. No one is saying what P1 did is right. Most of the people is asking TS to just suck it up on the lousy promotion campaign and think about whether it's a good deal or not.

Is paying RM149 for 2Mbps of wireless broadband a rip off?

Let's compare Korea then. The pioneer of WiMAX - Korea Telecom is offering

1Mbps (Max) with 6GB limit at MYR108.176 (KRW40000)

and P1 is offering

1-2Mbps (Average) with 10GB limit at MYR149.00

I would say P1 have a good deal no? Let have this discussion with more facts rather than to challenging whether a person has been to a country before and argument based on "i think".

I suppose you are not talking about mobile broadband. I'm quite near to R&D data and the best I've seen with my own eyes is about 30Mbps (UDP) per terminal. Let me just say this before everyone's eyes starts to pop out from their socket, it was done in a very controlled environment. Do read up WiMAX 16m or 3GPP R10 standard, that can give you 100Mbps.

BTW, many have problem with setting up an indoor base station for coverage. I guess they don't realize that for tall buildings like KLCC (my office), indoor system is used to provide GSM/UMTS coverage.

Indoor coverage is meant to be covered by indoor BS. If P1 did not place the BS there, the speed test that the user do will be flawed. Please don't tell me your house is as big as KL Convention Center and you have more than 10K people walking around your house.

Side note: I'm not working for any operator. I'm a Solutions Engineer for a MNC vendor.

I'll continue to provide technical information until I give up on forumers who are ignorant (exist in both sides of the argument).

155Mbps can be realized by providing a microwave link (this is a very mature technology). You are guaranteed 155Mbps to the operator's core but I guess there will be bottleneck all the way to the source of your download.

New microwave links can go up to 400Mbps. All of this comes at a condition, your connection is fixed and you will need to install dishes double the size of Astro dish at your roof. This is not mobile BB, this is fixed BB.

I doubt this service can be provided with the price of RM1000.

A typical microwave link (equipment only without installation and such) cost USD15K-25K.

I guess some people is too ignorant about technology limitation. Tell me, do you use the rice pot as your bowl for dinner?

Different things is meant to be used differently. The equipment on wheel are much smaller version of a normal base station.
